If you’re experiencing problems with your multipoint lock or want to learn more about how these systems work, this guide will give you everything you need to know about multipoint locking system troubleshooting and repair.

Why does the multipoint door lock stop working?

There can be many reasons why your multipoint door lock is not working properly.

  • The most common reason is that it was not securely installed. If you recently installed the multipoint door lock and it stopped working, it probably needs adjustments or repair work.
  • Wiring issues are another reason a multipoint door lock may not work properly. For example, if you have a multipoint door lock connected to an old-fashioned switch, it might not work as well as one connected directly to an electrical outlet because there are no wires between them.
  • A third possible cause of malfunctioning your multipoint door lock system could be mechanical problems with the locking mechanism. This could be due to a broken part or plain wear and tear on the multipoint door lock.

Multipoint door lock Misalignment

Multipoint door lock Misalignment

Multipoint door locks are not always easy to install and can lead to misalignment. When a multipoint lock is misaligned, it will not function properly. This means the deadbolt cannot be inserted into the strike without force.

This problem is usually caused by a broken gearbox or a misaligned locking bar. If your door lock is misaligned, you’ll see an uneven gap between the edge of your door frame and where it meets the strike plate.

If this happens, remove and reattach the multipoint lock until it aligns perfectly with its frame. If this does not work, you must replace your multipoint lock with one installed correctly.

You can adjust this by removing and reinstalling screws inside the doorframe to get everything lined up again. This can happen if you’ve used a screwdriver instead of an Allen key when working with your lockset or if someone has taken it apart before and put it back together incorrectly.

The gearbox allows your deadbolt to move freely within your multipoint lock system and connect with a strike when unlocked.

If your multipoint door lock has become jammed, manually remove it from its casing and ensure it’s not clogged with dirt or debris (like leaves!).

You can also try flushing out keyways with solvent if there is no obstruction on the inside of them; this will help ensure that all moving parts are working properly so they don’t get stuck again later on down the line!

If that doesn’t work, try using a wire brush on both sides of each part involved—this should help clear out any debris causing friction between moving parts.

Drooping handles or levers

Another issue causing trouble with your multipoint locking system is drooping handles or levers on either side of the door.

When this happens, it is difficult for you to unlock or engage your multipoint locking system. You may also have trouble turning your key to unlock your door because these handles/levers have become stuck due to rust or dirt buildup.

If you’re having difficulty turning your key to unlock or engage your multipoint unlocking system, but everything else seems okay with how things look inside (i.e., no loose screws), try lubricating each component inside with WD40 spray before trying again next time around.

If you’re still having trouble turning your key to unlock or engaging your multipoint locking system after lubricating everything, you may have a problem with the lock cylinder. This is often due to wear and tear over time, which causes your lock cylinder to become worn out.

Multipoint locks become stuck or find it difficult to turn.

One of the biggest issues with multipoint locks is that they can become stuck or difficult to turn. If this happens, there could be an issue with the alignment of components within your locking mechanism, which needs to be reset by a professional locksmith so that all points are operating correctly again.

The Multipoint door lock is slightly loose.

Suppose your multipoint locking system occasionally feels slightly loose when turning it. In that case, dirt or other debris may be stuck between two pieces of metal inside the mechanism.

To fix this problem, please use a cotton swab dipped in rubbing alcohol (rather than vinegar) to clean those two pieces of metal as best as possible—you should be able to remove any leftover dirt particles this way before reassembling everything back together again!

If you’re still having trouble with your multipoint door lock, try cleaning all the parts again and checking to ensure they’re all firmly connected. If this doesn’t work, there’s possibly something wrong with the mechanism itself, and you’ll need to replace it.

The multipoint locks handle won’t return.

The handle won't return

The handle should return automatically when you release the button or turn the key. If it doesn’t, there may be an issue with the lock itself or one of its parts (e.g., a broken spring).

  • Check that all cables are connected securely and test whether they work properly by pressing in on them with force (but don’t pull too hard!) If this doesn’t help, try twisting all screws again and replacing cables if necessary.
  • Check the lock cylinder. If the handle doesn’t return after being depressed, the problem is most likely with your lock cylinder rather than anything else in your system. This can happen when debris inside the lock cylinder blocks it from working properly.
  • They have broken return springs. To repair this problem, remove the lock and replace the damaged parts.

The key turns, but the latch won’t retract

The key turns, but the latch won't retract

The key turns, but the latch won’t retract. This can be caused by a dirty or worn tumbler assembly or misaligned cylinder pins that prevent it from being retracted properly.

You’ll need to remove the door from its hinges, disassemble the lock’s interior components (including screws), clean everything thoroughly with solvent and lubricant, reassemble everything correctly using grease on all moving parts (the most important part), then test out its functionality before reinstalling it back onto your door frame!

Also, This may be a problem with either your key cylinder or latch assembly; try removing these parts from each other and reassembling them until they work together again.

You may need to replace the lock if they still don’t work.

Keeping the locks well-maintained is important if you have a multipoint door lock. That’s because they’re more complicated than the average lock. This means that they’ll need more maintenance than an ordinary lock.

To maintain the multipoint door locks:

  • Please keep it clean. Regularly clean your multipoint door lock and surrounding areas to prevent dirt, dust, and grime buildup.
  • Keep it lubricated. The multipoint door lock requires regular lubrication to ensure its smooth operation, so you might want to invest in some quality multipoint door lock oil for this purpose.
  • Maintain the correct tension spring tension on your multipoint door lockset before installing or repairing parts of the multipoint locking system.
  • Check whether all components needed for properly functioning your multipoint locking system are present (for example, keyed cylinder boxes, keysets, etc.)
  • Clean the multipoint door lock regularly, especially around the hinges, if you can see any dirt buildup there. Just use a damp cloth with a little soap to scrub away any grime or debris that’s built up.
  • Consider replacing worn-out parts such as cables and springs with new ones if your multipoint door lock isn’t functioning properly anymore—it may just help get things working again more smoothly!


As you can see from the above information, multipoint door locks are a great way to secure your home. They offer excellent security and are much more convenient than traditional locks. However, they do have some disadvantages as well. For more help with multipoint door locks, please contact ShineACS Locks at any time.
