How to Fix a Door Lock That Won't Turn - 7 Common Lock Problems and How to Fix Them

Do you have a door lock that just won't turn? If so, you're not alone. Many people experience this problem every day. In this blog post, we will discuss the seven most common lock problems and how to fix them.

We will also provide tips on how to prevent these problems from occurring in the first place. So, if you're having trouble with your door lock, don't worry - we've got you covered!

Problem #01 - The Lock Is Stuck Or Jammed

Having a door lock that is stuck or jammed can be extremely frustrating, especially when you're in a hurry to get somewhere. This problem is usually caused by dirt and grime build-up within the locking mechanism.

A door lock mechanism is very delicate, so even a small amount of dirt can cause it to become stuck. The good news is that this problem is relatively easy to fix. You only need a can of compressed air and a few minutes to clean out the mechanism.

Here's how to do it:

  • Take off the door knob - Start by taking off the door knob or handle. This will give you access to the inner workings of the lock.

  • Use compressed air - Use compressed air to blow out dirt and debris inside the mechanism.

  • Reassemble - Once the mechanism is clean, reassemble the door knob or handle and use the lock again.

You may need to lubricate the lock if this doesn't fix the problem. You can use various lubricants, but we recommend using WD-40. Your jammed lock should now be working correctly!

Problem #02 - Misaligned Door Latch

When the door latch is out of alignment, it can also cause the door lock to become misaligned. This usually happens when the door is forced open or closed too hard, causing the latch to become skewed.

To fix this problem, you will need to remove the screws that hold the latch in place and realign it with the strike plate. Once you have done this, you can screw the latch back into place. Dont forget to test the lock before you put everything away.

Problem #03 - Stuck or Broken Key

A broken key is one of the most common problems people have with door locks. If your key is stuck in the lock or has broken off inside, you'll need to remove it before you can continue using the lock.

There are several ways to remove a broken key from a door lock. One way is to use a pair of needle-nose pliers to grab the end of the key and pull it out. Another way is to use a broken key extractor, a tool specifically designed for this purpose.

Problem #04 - Loose or Worn-Out Lock Parts

If your door lock is starting to feel loose or the parts are starting to show signs of wear and tear, it's time to replace them. Luckily, this is a relatively easy fix. Simply remove the door hinge screws and the door knob, then replace them with new ones.

Door knob locks are usually pretty cheap, so you shouldn't have to spend more than a few dollars on this fix. A loose door lock is a security hazard, so fixing it as soon as possible is essential.

Problem #05 - Improperly Installed Lock

We've all been there - you go to lock your door, and the key won't go in. If this happens, it's likely because the lock is installed incorrectly. This is a pretty common problem, especially with new construction.

The good news is it's an easy fix. All you need is a screwdriver. Just remove the screws that are holding the lock in place, and then re-insert them. Make sure they're tight, but don't over-tighten them. Dont use a power drill, as this can strip the screws. This should fix the problem and allow you to lock your door.

Problem #06 - Damaged or Worn-Out Lock Cylinder

The lock cylinder is the part of the lock that the key goes into. Over time, this part can become damaged or worn out, making it difficult to insert or remove the key. If this happens, you'll need to replace the entire lock. To do this, you'll need to:

  • Remove the old lock cylinder from the door - To remove the old lock cylinder, you'll first need to remove the screws that hold it in place. Once the screws are removed, you should be able to pull out the old lock cylinder simply.

  • Install the new lock cylinder - To install the new lock cylinder, insert it into the hole where the old one was located. Make sure it's turned to the correct position so the key will go in easily.

  • Test the new lock cylinder - Once it is in place, test it out by inserting and removing the key a few times. If it seems to be working properly, then you're all done!

A damaged or worn-out lock cylinder is a common problem that can be easily fixed with a little time and effort. With these steps, you'll have your door working like new in no time.

Problem #07 - Door Distortion

Door distortion is another common issue that can cause your door lock to become misaligned. This can be caused by several things, such as weather changes or even the house settling over time.

If you notice that your door is starting to warp or become misshapen, it's essential to take action immediately. Otherwise, you may find that your door won't close properly or that the lock won't engage correctly.

To fix this problem, you'll need to remove the door from its hinges and then use a straight edge to realign it. Once you've done that, you can reattach the door, and hopefully, your lock will now work as intended. However, if the door is severely damaged, you may need to replace it entirely.

These are just a few of the most common issues that can cause your door lock to fail. If you're having trouble with your lock, don't hesitate to contact a professional locksmith for assistance.

Step By Step On How To Fix A Door Lock That Won't Turn

If your door lock is giving you trouble, don't worry - you're not alone. Door locks are notoriously finicky and can often start acting up for no apparent reason. But before you call a locksmith, there are a few things you can try to fix the problem yourself.

What you need:
  • A screwdriver

  • A hammer

  • WD-40 or another lubricant

Now that you have your tools, follow these steps to fix a door lock that won't turn:

Step #01 - Examine the lock

The first step is to take a close look at the lock. Is it lost? Are there any visible signs of damage? If so, then that may be why the lock won't turn. Try tightening the screws with a screwdriver. If that doesn't work, you may need to replace the entire lock.

Step #02 - Lubricate the lock

If the lock is not damaged and it's still not turning, the problem may be that it is simply too dry. WD-40 or another lubricant can help with this. Spray lubricant into the keyhole and then try turning the lock again. The entire lock system may need to be lubricated if this doesn't work.

Step #03 - Check the weather stripping

If your door lock is still giving you trouble, the next step is to check the weather stripping. If the weather stripping is old or damaged, it can prevent the door from sealing properly, which can cause the lock to malfunction. Replacing the weather stripping is a relatively easy DIY project.

Step #04 - Check the strike plate

The strike plate is the metal piece the bolt connects to when the door is locked. If the strike plate is loose, it can prevent the bolt from connecting properly, which will make it difficult to turn the lock. Tighten the screws on the strike plate with a screwdriver. If that doesn't work, you may need to replace the strike plate.

Step #05 - Check the key

If the lock is still not turning, examine the key. Is it bent or damaged in any way? If so, that may be why the lock won't turn. Try using a different key. If that doesn't work, you may need to have the key replaced.

Step #06 - Check the deadbolt

If your door has a deadbolt, it may be the problem. Deadbolts can often become jammed, making it difficult to turn the lock. To fix a jammed deadbolt, use a hammer to tap on the side of the bolt. This will usually dislodge the jam.

Step #07 - Call a locksmith

If you've tried all of these steps and the lock still won't turn, then it's time to call a locksmith. They will be able to diagnose the problem and fix it quickly.

Fixing a door lock that won't turn can be a frustrating experience, but it's usually not a difficult problem to fix. With a little patience and the right tools, you can usually get the lock working again in no time.

How to Prevent a Door Lock from Becoming Stuck in the Future?

If you want to prevent your door lock from becoming stuck in the future, you can do a few things. First, make sure the locking mechanism is well-oiled. This will help to keep it moving smoothly. You can also try using a silicone spray lubricant on the outside of the keyhole.

This will create a barrier that will keep dirt and debris from getting inside, causing the lock to stick. Finally, make sure you regularly clean the keyhole with a soft cloth to remove any build-up of dirt and grime.

If you follow these steps, you should be able to keep your door lock from becoming stuck in the future. So, don't wait until it's too late - take action now to prevent this problem from happening.

7 Different Types of Door Locks

There are a variety of different types of door locks that you can choose from, depending on your needs. Here is a brief overview of seven different types of door locks:

  1. Deadbolt locks - Deadbolt locks are one of the most common types of door locks. They are usually used in combination with a doorknob lock. Deadbolts have a bolt that goes into the door frame, making it very difficult to force open. Deadbolt locks come in two main types: single-cylinder and double-cylinder.

  2. Mortise locks - It is a powerful locking system that is common in exterior doors. A mortise lock has a rectangular box cut into the door, and this box houses the locking mechanisms. Mortise locks are very strong and secure, but they can be challenging to install and repair.

  3. Smart locks - Smart locks are versatile and can be controlled via an app, allowing you to remotely lock and unlock your door as well as set up access schedules for other people. However, they are also more expensive than traditional locks and require a power source (usually batteries).

  4. Padlocks - Padlocks are freestanding locks that are not permanently attached to anything. They are the simplest type of lock and usually have a basic keyed or combination locking mechanism. Padlocks are often used to secure gates, fences, sheds, and other outdoor structures.

  5. Knob Locks - A knob lock is a type of door lock that is typically used on interior doors. It consists of a knob that is turned to open or close the door. Knob locks are often used in conjunction with deadbolts to provide additional security.

  6. Cam locks - It consists of a cylinder that fits into a hole in the door and is held in place by a cam. The cam is usually attached to the cylinder by a set screw. Cam locks are used on various doors, including office doors, filing cabinets, and lockers. They are cylindrical locks that are operated by a key, and they have a cam that fits into a hole in the door.

  7. Keypad locks - Keypad locks are electronic locks that use a keypad to enter a code, which is then used to open the lock. Keypad locks are becoming increasingly popular as they offer a higher level of security than traditional locks. These locks are often used on doors that lead to sensitive areas, such as offices or homes.
