Maintaining Multipoint Locking Doors

Maintaining Multipoint Locking Doors

Multipoint mechanism

Ensure the Longevity and Security of Your Doors

Multipoint locking doors are increasingly popular in homes and commercial properties due to their superior security features. With locks engaging at multiple points along the frame, these doors offer enhanced protection from break-ins and better sealing against external elements. However, like any mechanical system, they require regular maintenance to ensure optimal performance and longevity. Below is a thorough guide on how to maintain these complex yet valuable systems.

Understanding Multipoint Locking Systems

Before delving into maintenance tips, it’s essential to understand what a multipoint locking system entails. These systems typically feature three or more locking points, which simultaneously engage when the door handle is lifted or turned. The locking points often include the main latch, deadbolt, and additional hooks or bolts along the edge of the door.

Why Maintenance Matters

Multipoint locking systems are key to your door’s security and efficiency. Proper maintenance ensures:

  • Consistent functionality: Prevent stiff mechanisms or misaligned locks that compromise security.
  • Prolonged lifespan: Reduce wear and tear by addressing minor issues before they escalate.
  • Enhanced energy efficiency: Maintain proper sealing to prevent drafts and energy loss.

Routine Maintenance Tips

1. Regular Cleaning

Dust and debris can accumulate inside the locking system, hindering smooth operation. To clean:

  • Use a soft cloth to wipe down the exterior parts of the lock.
  • For internal components, employ a dry brush or compressed air to remove dust.
  • Avoid using water or harsh cleaning agents that could corrode metal components.

2. Lubrication

Proper lubrication is vital for keeping the locking mechanism smooth and functional.

  • Apply a silicone-based lubricant or specialist lock lubricant to all moving parts, such as latches, hooks, and bolts.
  • Avoid oil-based lubricants, as they can attract dirt and create a sticky residue.
  • Conduct lubrication every six months or as needed, depending on use.

3. Inspect Alignment

Misalignment can cause difficulty in locking or closing the door. Check for:

  • Uneven gaps between the door and frame when closed.
  • Strain or resistance when engaging the locks.

If misalignment occurs:

  • Adjust the strike plates on the frame using a screwdriver.
  • Ensure the door hinges are tightened and properly aligned.

4. Check for Wear and Tear

Over time, components of the locking system may wear out. Inspect for:

  • Cracks, rust, or deformities in the locking points.
  • Loose screws or bolts in the assembly.
  • Handle mechanisms that jiggle or feel unstable.

Replace damaged parts promptly to avoid compromising the entire system.

Advanced Maintenance Practices

1. Professional Inspection

While routine checks are beneficial, a professional locksmith or technician can perform a detailed inspection of your multipoint locking system. Annual inspections can:

  • Identify hidden issues, such as internal wear or corrosion.
  • Provide adjustments that require specialised tools or expertise.

2. Replacing Components

If your locking system shows signs of significant damage or is consistently malfunctioning, it may be time to replace individual components. This may include:

  • Worn-out handles or levers.
  • Damaged locks or strike plates.
  • Hooks or bolts that no longer engage correctly.

Ensure replacements are compatible with your existing system to maintain effectiveness.

Best Practices for Long-Term Care

1. Avoid Excessive Force

Never force the door handle or locks if they resist movement. Doing so can cause damage to the internal components. Instead, investigate and resolve the issue.

2. Protect Against Moisture

Multipoint locking systems are susceptible to rust caused by moisture. Protect your locks by:

  • Installing weatherstripping to minimise exposure to rain or humidity.
  • Avoiding water-based cleaning methods.
  • Applying anti-corrosion spray to exposed metal parts.

3. Use the Locks Regularly

Engage the locks frequently to ensure all components remain active and functional. Prolonged inactivity can lead to stiffness or mechanical failure.

Common Mistakes to Avoid

1. Neglecting Routine Checks

Skipping inspections can allow minor issues to worsen over time, leading to expensive repairs.

2. Using Incorrect Lubricants

Oil-based products can cause dirt buildup, reducing the efficiency of the locking mechanism.

3. Ignoring Signs of Damage

Failing to address visible wear or malfunction may compromise security and lead to system failure.

Conclusion

Multipoint locking doors provide unmatched security and efficiency, making them a valuable asset to your property. By implementing regular maintenance practices, such as cleaning, lubrication, alignment checks, and professional inspections, you can ensure the system operates smoothly for years to come. Avoid common mistakes and stay vigilant for signs of wear and tear—your diligence will pay off in improved safety, energy efficiency, and the longevity of your door system. Proper care is not just an investment in your security but also a guarantee of peace of mind.

Locksmiths most commonly asked questions

Locksmiths most commonly asked questions:

The questions that, as a locksmith, I am most commonly asked are here with my answers

Do Skeleton Keys open all locks?

A key to open all locks is only found in magical fantasy. Even us locksmiths need many different lock picks for the different types of locks we come across, so that hero you see on the TV who carries a few needle like implements in a little pouch, is only making a small representation of what is really needed, and even then, the speed shown would be for very easy, smooth running locks. That being said, each lock type and brand have a finite number of combinations and if you were to try your house key in enough other houses using the same brands and lock type, you will find houses that you can enter with ease. This is an important point when moving into a newly built home on a large estate. The average new house comes with front, back and patio doors. A 500 house estate means around 1500 locks and the developer will use the same brand and lock type on every one of them. Locking doors to garages and sheds could easily make that 2,500. With that many locks, the statistics say there is an extremely good chance someone else’s key on that estate will fit your lock. So, it is very good advice to change your locks, even on a new home, preferably to a different brand to all the rest.

How will the locksmith gain entry?

There are many ways to bypass a lock. You might even want to see for yourself how it is done. Please do not be offended if the locksmith asks you to step away while he works. Some techniques require a learned feel or special technique. Watching the locksmith work can show people how to get into other people’s homes which is not really a morally good thing. Also, watching the locksmith and trying to replicate what they do next time, might lead to bigger complications and an even bigger bill. Besides, if they are given room to concentrate, they can work faster, getting you in quicker.

Why do locksmiths charge so much?

Hopefully, you only see the locksmith for a very short time. What you don’t see are the endless hours driving between jobs. It is very that two people have an emergency next door to each other and usually the case that a locksmith will criss-cross his patch several times in the same day. In cities the patch may be small but the traffic will be horrendous and rurally, the patch is much bigger due to lack of population density. On top of that, locksmiths need to keep up with the latest changes in law and products, keep on top of their own accounts, maintain their vehicles, replace tools and nowadays, write blogs! There might be additional training programs. This doesn’t just mean the cost of the course itself, but losing however many days work the course entails. Then there is the time spent ordering parts online or time spent in shops purchasing tools, etc. As a cost example, I have to do two jobs a month just to pay for the chisels and drill bits I will need to replace each and every month. So you can see, there is a lot more cost involved than just the time the locksmith spends with you.

If I have my locks changed, how many keys do I get and where do I get more cut?

Most locks come with two or three keys. If you are booking a lock change for a future date, it is wise to get the number of keys you require ordered with the lock. This way, you can guarantee the keys will have been tested in that lock before they get to you. Some locksmiths can cut keys on site which again is a sure way to see they are tested. The alternative is to go to your local engraver/cobbler who will usually provide key cutting services. But here you are chancing your luck, because you will have to wait until you get home to try the keys and if they don’t work, you have to go all the way back to the shop again, still with no guarantee it won’t happen again. Chances are, key cutting outlets will not use genuine branded blanks either. You might think chain key cutters would be the best option but these have high staff turnover and very basic training. Every time I have been recalled to a faulty lock that I have installed, the problem has been poorly cut keys from chain stores. If getting keys cut, always ask for genuine branded blanks that should show the same brand name on the head of the key as the one you getting copied. Many will tell you the non-brands are just as good, but this just isn’t so. Demand genuine. Leave a deposit and pick up the keys a couple of days later if needed. This could save you a much more pricey second visit from the locksmith. Never use an already copied key to cut another. If you have lost your original keys, get a new lock an order the appropriate number of keys with it.

What is British Standard and why do I need it?

British Standard or BS3621 is a rating for the effectiveness of locks against certain attacks that includes, picking, drilling, slipping, bumping and a whole host of other terms you might not be familiar with. Your home insurance will demand your locks on wooden doors be up to this standard. While it is not an insurance requirement for doors where you have to lift the handles before locking, every locksmith will correctly tell you that you should a BS3621 lock on these doors as well because without them, the intruder can enter your home in under 60 seconds with no power tools. Even if the intruder does get in through a BS3621 rated lock, your insurance might not pay out if another door on your house is not up to standard, so check now that all your final exit doors have a BS3621 kite mark.

What is a fair price for my locksmith?

This is a bit of a minefield. The nationals will charge more because they have to make their profits, pay office staff and pay the locksmith they sub-contract to do the work, but they will do the work that saves you ringing several people in an emergency, and many local locksmiths rely on the work that comes in from the nationals while they get themselves established. That aside, locksmiths seem to have a standard rate, evening rate and through the night rate, plus weekend rates and bank holiday rates. If possible, you should check the locksmith’s website to see if they have any indication of what you might expect to pay. Personally, I have one rate no matter what time of day of what day of the week it might happen to be. But if you have the time, you should ring two or three locksmiths. The cheapest one will probably be the least experienced or hiding costs until he gets there. The most expensive one will be over pricing and you should usually go with the one in the middle, especially if these prices are wildly different. Be sure to get quote on the phone, a revised quote once the locksmith has visually assessed the job, and find out if the price includes VAT. You also want the locksmith to inform you if anything happens that will cause a price increase. The locksmith should tell you about any potential price increase reasons before continuation.

How long does it take the locksmith to open my locked door?

This can be seconds to a very long time. Locks are often worn, rusty or might have something causing a jamb. The locksmith is wary of damaging your door so will take time and care to make sure the job is done quickly with the least amount of damage. A simple latch lock might be opened in seconds, but a seized multi-point locking system can be very difficult to open without causing damage to the door. Rest assured, the locksmith wants to get you in just as quickly as you want to be in yourself. With car locks, the picks require feel of springs inside the lock itself. If the lock is old, this feel can be difficult, or if the internal workings are too loose, the individual parts can keep passing beyond their opening point, making a three minute job last an age. Patience is your only requirement.

Why do I need to pay on the day?

You are paying for a service and often new products. Most locksmiths are sole traders and unable to run back accounts like big companies. The costs of materials and van/tool maintenance keeps thing tight all the time. We just cannot add tracking who owes what where and when all the time in addition to everything else. Now that doesn’t mean we are heartless and unsympathetic to those who just don’t have the means to pay in an emergency situation. If you genuinely cannot pay on the day, make the locksmith aware before work commences and something can usually be worked out, but be aware, should you not pay the locksmith within an agreed time, he may well charge late payment fees or you might just find yourself paying more should you need that locksmith in another emergency.

So, there you go, the locksmiths most commonly asked questions !

 


Fire Regulation Locks

Thumb turn exit lock - Fire Regulation Locks

Thumb turn exit – Fire Regulation Locks

Fire Regulation Locks

Last week I quoted a customer for multiple locks within a building of flats in Cromer. I was expecting to wait a while for the confirmation of the job as three of the flats are holiday lets and all four have different owners. In fact, my point of contact phoned to give the job the go ahead very quickly as the neighbouring building had a fire and everyone had to be evacuated for safety. Thankfully, no one was hurt, but guests in the holiday lets did have issues trying to find keys they had placed away from the doors in properties they were not used to.

A thumb turn, keyless escape can be a reduction in security and goes against every bit of best security advice. However, in the event of a fire, your guests are probably going to be sleepy and panicked, the seconds it takes to find the place they have put the keys could be the difference between life and death.

The fire regulations have been in place for a year at time of writing. While a grey area on time was given to get the various jobs done, I doubt any insurance company will pay out after so long should the worst happen. That means those involved in any incidents can chase you, the owner for negligence and your letting agent as well. You could even face criminal charges.

Link to Gov guidance here: https://assets.publishing.service.gov.uk/media/64257cff2fa8480013ec0fec/A_guide_to_making_your_small_paying-guest-accommodation_safe_from_fire.pdf

If you have multiple doors, you might think just the front door and back door are adequate to change, but you must look at every room and think to your self if there were a fire the other side of that room’s inner door, how will someone in a panic get out? If there is a big room with two or more outer doors, will changing one be enough? Is it possible a fire in the middle of that room could cut off access to escape? I know it can be expensive, but nowhere near as expensive as a court battle, even if you win.

If you own a holiday let property or run a property let business, it is now past time for you to have your exit doors converted to fire regulation keyless escape.

Price increases 2022

Price Increases 2022

Here at AC Locksmiths Norfolk, I have always been proud to offer my customers first rate work at competitive prices. Unlike most locksmiths, I display my prices on my website, I do not raise my prices if you call me out at 3am, at the weekend or on a bank holiday.  On top of this, I have also kept under the VAT threshold to ensure the price I quote, is the price you get. Despite Brexit and Covid, I have not changed my labour rates in over four years.

Unfortunately, this now must change. I have looked at adjusting the prices of my products. I have looked at smaller changes to products and labour. But in the end, I think it fairer to all my customers to put the change on labour rates only.

If I need to make a second visit though, I will not charge labour when I come back to you. I will still offer free security checks with no obligation quotes, and if I do a door adjustment on UPVC doors, I will still give you a free recall if your door needs it within the next 6 months. No other locksmith I know of will do that for you.

So as of today 07/03/2022, my labour rates will be going up to £75 for all new business.

Please see my prices page for more information

This announcement supersedes all previous blog references to pricing.

UPVC window valeting service

New Service!

Window recesses before cleaning & servicing

Clean window frame

Hope you are all safe and well in these strange times.

Most of my customers know that I am far from an average locksmith. In addition to emergency call outs for domestic and commercial properties, I offer security upgrades, Smart alarm and CCTV sysytems, video doorbells, car key production, locked car entry, and free security checks. In some cases, I even do light house clearance jobs
And now, I am offering something more. As soon as this lockdown is over, I will be offering a UPVC window valeting service. This is not intended to compete with or be anything like your normal window cleaner who might turn up and give your glass a quick shine. No, this is making the whole window look great again.

There will be three levels of service:

Bronze level;

This will clean the outside of your windows, including frames. It will start with getting rid of all those old cobwebs that gather dust where the frame meets the brickwork. The window frame is then thoroughly cleaned. You will need to leave the window open as this service will include cleaning out the inner recess of all opening windows, getting rid of more webs and any other creepy crawly evidence. Everything will be done to clean all accessible areas from outside the property.

Before

 

After

 

Mildew removed – before

Mildew removed – after

Silver level;

This picks up where Bronze left off. I now come inside your property and clean the insides of your windows, double checking any parts of the inner recess and window itself that I might not have been able to see from the outside. Your windows will be a sparkling frame you want to look out of again.

Before

After


Gold level;

Here you get everything in Bronze and Silver, but now we remove the opening window so that we can see and get to every nook and cranny that might have been missed before. We will then service the window mechanism, checking for signs damage. Where possible, we will re-align problem windows so that they work more easily and if new mechanisms are needed, these can be ordered and fitted with no labour fee on the date of fitting (ie just the cost of the materials). Finally, where needed, anti-mildew spray will be applied to sills and areas that are prone.

Window shuts, mechanism cleaned & serviced

As with all my work, I want to make pricing fair and even for all my customers. This is not a quick splash the window with soapy water and wipe it away type service. And while I do not waste time while working and will certainly not charge time spent chatting if you happen to make me a cup of tea, the most transparent way to price this work, is to charge my standard labour rate of £65 per hour. Obviously this will mean you get more windows completed in an hour of Bronze level than you would at Silver or Gold. This will also give you, the customer, flexibility. You might tell me to only do certain windows to certain levels, mixing what you need to suite you. Alternatively, you might tell me to work for three hours this week and then come back and do another three hours next week or even next month, depending on budget capabilities.

In the first instance, this work will only be available for easily accessible ground floor windows. All inner window sills should be cleared of any decoration and any hanging window decorations should also be taken down to avoid accidental damage or possible dirt spatter.

If you have an interest in this service once the current lockdown has been lifted, please let me know via any of the methods on my contact page. In the meantime, my standard services are still available whilst observing social distancing, using anti-bacterial cleaners and wearing PPE where possible.

Car Key Replacement FAQs

AC locksmiths Auto

  1. What is the difference between getting my replacement key from the manufacturer and an auto locksmith?

The manufacturer will usually be able to have your key replaced just from knowing your vehicle ID. You usually get your replacement key within the week. You know your manufacturer will have the key type you require.

The auto locksmith will have the ability to generate a new key on the spot. While it might not be a genuine brand replacement, your new key will be just as good (if not better) than the manufacturer key. The auto locksmith can reprogram your vehicle on the spot, so that any lost/stolen keys are unable to start the vehicle. The auto locksmith comes to you, meaning you can still go to work on time. Most of the time, you will pay a lot less for the convenience of an auto locksmith.

  1. What is cut to copy?

This is where the key is cut using the existing key as a template.

  1. What is cut to code?

Some vehicle keys can be cut using codes taken from the vehicle VIN number or from other sources.

  1. What is key cloning?

This is where the key is completely copied including the data on the transponder that talks to the car. While there may be two keys, the car will believe there is only one. This is important to know because some vehicles must have two separate keys programmed.

  1. What is a vehicle PIN?

This is a code that works like the pin number on your cash card. Without your pin, you can’t draw out cash. Without a vehicle PIN, you can’t extract the information needed to program new keys.

  1. Can I buy replacement keys on line?

Yes, and they can be quite cheap. But often, there are hidden extras, like programming the remotes to your car.

  1. Can I call my breakdown service company if I lock my keys in my car?

Yes you can, but they often call an auto locksmith and you then have to pay. As an example, I was called by a breakdown service provider recently. The breakdown engineer took an hour to get to them, spent two hours trying to fish the keys out of the vehicle with the top of the door wedged slightly open and failed. He called me. Within 45 minutes, I had arrived, opened the vehicle and was on my way home.

  1. What are the most common mistakes people make?

In no particular order; shutting keys in the boot without having the main doors unlocked, leaving the spare key 200 miles away at home when going on holiday, letting children play with the car keys, letting the remotes go way past their best condition, treating remotes poorly, letting batteries die, losing keys on the beach, not getting a replacement when the first key is lost, buying a vehicle with only one key (who has the other, and do they know your address?

  1. Why should I get new keys when buying a second hand car?

How well do you know the seller? Most of us buy cars from someone we don’t know. We often give over our address if the vehicle is being delivered, or if we are taking finance, etc. But we don’t know if the seller has already had extra keys made. If you are paying out thousands of pounds to have a car, is it not wise to pay a little more and make sure the vehicle will only drive away from your driveway with keys you possess?

  1. How do I know I am paying the right price?

Get quotes. Two or three at least. A good auto locksmith will advertise prices on their website, but these will be guidance only as the cost of parts and software packages vary a lot between manufacturers. Some work is simple, other work might involve having to get behind your dashboard and removal of computer chips. A difference of just one year can make a particular vehicle much harder to deal with. In rare cases, the auto locksmith might have to walk away unable to do anything. If he is any good, he will not charge you when this happens, unless you have made some prior agreement. If you get three quotes, and one is much less than the other two, investigate further before accepting the cheapest quote. Has he quoted the full job, or been a bit vague? People who quote too little are often not properly trained and are more likely to do something that harms the computer in your vehicle. If that problem takes a while to arise, they will not be around when you go after them for damages.

If you have any questions you would like answered, please contact through any method on the contacts page.

Scandinavian Locks

All about Scandinavian locks

All abount Scandanavian locks

While Scandinavian multi-point locking mechanisms are not very common in Norfolk, there are enough of them to warrant a mention.

The locks look something like this :

Scandanavian locks
These locks operate with a mechanism that typically employs two hooks that come out from the door and fit into specially cut spaces within the door frame, just like many upvc doors. They are always fitted to wooden doors, which is where the problems start.

In Scandinavian countries they are geared up for cold, damp weather and treat woods accordingly. Here in the UK, we seem to use any wood going and think a coat of paint or varnish will be adequate. That works okay for standard locks where all the working parts are protected within a lock case, but locking mechanisms have exposed moving parts which get pinched and moved by doors that expand and contract in wet weather. The untreated inside of UK doors holds water like a sponge, right next to the metal of these mechanisms which quickly become prone to rust. The problem is compounded by the fact that there used to be several variants of these mechanisms available, but now all but one design have been discontinued, meaning that if your mechanism does go wrong, the replacement is likely to be different. An example being a job I have recently done where everything looked identical, but the door needed much chisel work to accept the replacement.

Scandanavian locks 2

The next problem is cost. These units are extremely expensive.  A complete set up can cost between £250 and £400 depending on who you use to fit the device with labour and VAT to be added to that figure.

Finally, these locks are not particularly secure. While many insurance companies will accept them as adequate, they do not get the British Standard 3621 rating I would recommend to feel properly protected.

If you think you might have Scandinavian locks and they have not been serviced recently, it might well be worth contacting your local locksmith to have a look at them, especially if they are hard to lock, or the handles have gone floppy. A little maintenance now, might save a lot of cost later, or at least alert you to the likely cost of replacement, rather than have it all come as a shock when you can least afford it.

Multi-point lock problems

Lock maintenance




In previous blogs I have mentioned the importance of regular lock maintenance. This has been highlighted recently, as I seem to be going through a series of cases where doors with multi-point locking systems seem to be causing problems. This is especially true when the doors have shoot bolts at the top and bottom of the doors.

The bolts themselves are never particularly strong, so if the system is engaged without the door being properly closed first, it is very easy to push these bolts out of shape, which then causes them to wear as they do not fit properly into the holes in the frame. I do see this happening a lot with French doors. UPVC doors are usually easier to correct as there are often adjustments that can be made, but wooden doors that warp, expand and contract with the weather, can be very tricky.

If your door handles are hard to raise, or you need to hold them up to turn the key, then there is likely to be a problem. Stand back and look to see if the doors are straight and even. Check they fit into the frame properly. Look for signs of wear caused by bolts scraping woodwork. If there are signs of damage, call your local locksmith while there is a chance the problem can be rectified.

Should you have any questions regarding this or any other issues mentioned in my blogs, please get in touch via any of the methods on my contacts page.

Post Winter Lock Maintenance

Damaged doors & lock maintenance

Spring is finally upon us and now is the time when we need to think about all the damage the wet weather has been doing to our doors and locks.
Spring house

Wooden doors will start contracting, as the moisture dries out of them and they may start to bang around in the breeze. Taking note of the problems of a recent customer, please be aware of the potential pitfalls of buying a draft excluding weather strip. If the weather strip is too thick, it can put strain on a mortice (chubb) lock and if you are having to push or pull the door when you turn the key, this will put undue pressure on the levers inside, which will inevitably break, locking you out at the worst possible time. A simple re-positioning of the lock keep in the door frame can alleviate the problem.

Wooden doors with multi-point locking mechanisms need extra attention. Over the winter, the swollen door will have been squeezing all the working parts and holding moisture around the metal, leading to rust. At the very minimum, these mechanisms should be oiled, however, calling your local locksmith to take the whole thing out of the door for a thorough examination might cost his call out fee, but could save you a lot more if the need for a complete new mechanism can be averted.

And with multi-point mechanisms in mind, many of us will be starting to use our patio doors now that things are warming up. These too, should be oiled now and at the end of summer. As a rule of thumb, double glazed doors where you have to lift the handles before turning key, should be as easy to operate with the door closed as they are when the door is open. So open the door and lock it, then close the door and lock it. If it is significantly more difficult to lock when the door is closed, you need to call your local locksmith to make the necessary adjustments. Again, a labour cost now is far better than the cost of a new mechanism.

If you own a holiday let property, now is the best time to have your locks looked at as the last thing you want is to have your locks fail when paying customers are using it. At best, you have to compensate the customer. At worst, you lose the business of that customer and all the potential recommendations they provide. What’s more, this is a business cost, so can be offset against your tax bill at the end of the financial year. What’s best – paying the tax man or having something to show for your money?

Experience has taught me that another time locks seem destined to fail is when pet owners go on holiday, leaving a friend or family member to come in daily to feed Tiddles, or water the plants. Most of us already feel we are burdening our neighbours when we ask them to do this, so how much worse will you feel if your lock breaks while they are in charge. Can they afford to pay for a locksmith in your absence? Will they have to take time off work waiting for a locksmith to come? While maintenance is not a guarantee that this will not happen, it certainly reduces the risk. Age of the lock and badly cut spare keys are the biggest contributors here, but poor maintenance is very high on the list of problems.

Should you have any questions regarding the above, please feel free to get in touch via any of the methods on my contacts page.

Different locks explained Part 4

Having looked at the locking barrels for double glazed doors in my previous blog, this blog is dedicated to the actual locking mechanisms themselves. There are several different ways in which they work.

The first and most basic is called a roller;

A C Locksmiths










When the door closes and you lift the handles, it simply rolls into position behind a keep that sits on your door frame and looks like this.
Roller














Very few doors only have rollers on their own nowadays as they are incredibly easy to bypass. Their main purpose is to hold the door a bit tighter when closed to stop draughts and they might be the only option on small doors. They are harder to bypass on smaller doors. Without giving the reader tips on how to break into a home, I can only suggest that if you have a double glazed door and it only has these rollers holding it in place, you might want to seek advice from your local locksmith to see if alternatives are available.

Over time, these rollers can shift a little in position, making the door difficult to lock and unlock. You can see from this next image that the correct sized allen key (hex key) can be inserted to rotate the roller. A quarter turn should be tried before attempting to lock the door again and if that does not work, then a further quarter turn and so on until you have established the problem is not with the roller or the problem is fixed.
Different locks explained
If this does not rectify the problem, it might mean the door has dropped a little and simply moving the keep up or down a few millimetres might do the job, but at this point, I would suggest calling your local locksmith as there could be more serious problems to contend with.
……………………………………………………………………………………………………

A step up from the roller is the mushroom;
Mushroom mechanism

It is more secure than the roller because it slides into a slotted keep where it holds tight. There is nothing to adjust on these mushrooms, so if it causes trouble, and the door cannot be adjusted, the only option is to move the keep accordingly.
……………………………………………………………………………………………………
Next we have hooks and bolts that come out of the mechanism like this:
Door mechanisms














The hooks and bolts themselves do not adjust, but again if the door is out of position, there are adjustments that can be made, this time to the keeps, that look something like this.
Double glazed door lock mechanisms
You can see from the picture that an allen key will allow you to adjust this keep. Some only allow backwards and forwards movement, so again, if you are unsure, please call your local locksmith.






Hopefully, you will never have to see behind the scenes of one of these mechanisms, so here is what goes on in the hook case itself.
Door mechanisms
You can see this one has a hook and bolt. These parts do not often go wrong by themselves, but when they do, the door is extremely difficult to open without damage to either the door itself or the door frame. Therefore basic maintenance is vital and any signs of stiffness when lifting the handles should be dealt with by a professional.




We can now take a look at the gearbox, or centre case, where all main action takes place. There are many brands of these each with differing sizes and shapes within the brand, so this picture is just one example;
Different locks














This example is called a double spindle and can be set up in two ways. The standard way is to have both handles operating through this hole.
Door mechanisms














In this case, the door will only be secure when the handles are lifted and the key is turned. However you can have handles where the inside handle operates through the top hole, but the outer handle is slightly lower and goes through this hole

In this case, everything operates exactly the same, but the lower hole does not allow the latch to pull back, meaning that you need the key to get back in. of course, if you are going further than the end of the garden, you should engage the locking mechanism completely as normal, but with this configuration, the door is at least technically secure.


These next two pictures show the hole that the locking barrel slides through and the barrel in place.

This is the simplest part of the lock. Everything inside above that, however is a minefield of cogs, levers and other moving parts. Please don’t expect your locksmith to be able to open these up and replace inner parts as with so many products around, knowledge of every one would be amazing and the locksmith would need an extra trailer to carry the spares, which would only be second hand as our suppliers do not provide anything other than complete products.

The centre keep for this part, looks something like this.
Locking mechanisms
And again, we can adjust certain parts like the latch keep on this one. Loosening these screws, allows the keep to move forwards and backwards.

I have come across many problems where simply adjusting this part, which may have moved when someone slammed the door, has rectified the situation. Quite often, the locking mechanism will not operate if the latch is still being pushed in, which it can if this part is in the wrong position.

Now, in this blog, I have mentioned doors dropping, which they often do. A sudden gust of wind, stroppy teens slamming, or even direct sunlight warping can all affect how the door sits in the frame.
Most modern upvc doors have hinges that are adjustable. If you have a door with hinges like this;

Then there is a good chance the door can be adjusted. The picture shows the one type of hinge that can be a little awkward because you have to prize it apart gently but firmly to get at the adjuster inside. Most actually have a plastic plug easily visible, which when removed, allow access to another allen key adjuster inside. If you are in any doubt, call your local locksmith. But if you feel like taking the job on yourself, half a turn of the adjuster should be all you move before trying to lock the door again. That should be enough to tell you if the door is easier or harder to lock. If harder, then you need to turn the opposite way. Remember, there are anything from two to four hinges that may be adjusted, so this is not an easy job.
