Why would a key stop working in a lock

Reasons a key might stop working in a lock

Over time, dirt, grime, and other debris can build up inside a lock, causing the key to stick or not work properly. If you’ve recently changed the type of key you’re using, that could also be the cause of the problem. In some cases, the tumblers inside the lock may need to be replaced.

Worn down key

One of the most common reasons a key stops working in a lock is because it has become worn down. Over time, the teeth on the key can become worn down or damaged, making it difficult or impossible to insert into the lock. If you think this might be the case, try using another key for the same lock to see if it works better. If it does, then you will need to have a new key made.

Worn down pins in the lock

The first thing that you should check if your key stops working in a lock is the pins. Over time, the pins in a lock can become worn down, which will cause them to no longer line up correctly with the key. If this is the case, you can either replace the pins in the lock, or have a new key made.

Dirty or misaligned key

If your key is old or worn, it may not make good contact with all the pins in the lock. Try cleaning your key with a wire brush or sandpaper. If that doesn’t work, you may need to have a new key made.

Another possibility is that the pins in the lock are misaligned. This can happen if the lock is damaged or if something has gotten stuck in it and jammed the pins. A locksmith can usually fix this problem.

How to fix a key that stops working in a lock

If your key has started to stick or jam in your lock, there are a few things you can do to try and fix the issue. First, try lubricating the key and the lock with WD-40 or a similar product. If that does not work, you may need to file down the key.

Clean the key

If your key is not working properly, the first thing you should do is clean it. A build-up of dirt and debris can prevent the key from correctly engaging with the pins in the lock, so give it a good wipe-down with a clean cloth. If the key is particularly dirty, you can also try cleaning it with a solvent like WD-40 or vinegar.

Clean the lock

If your key stops working in a lock, the first thing you should do is clean the lock. A dirty lock can cause a key to get stuck or not work at all. To clean a lock, you will need a can of compressed air, a small brush and some WD-40.

Start by spraying the compressed air into the keyhole to remove any dirt or debris. Next, use the small brush to clean the inside of the keyhole. Finally, spray a generous amount of WD-40 into the keyhole and insert your key. Turn it back and forth a few times to make sure it’s lubricated.

Realign the pins in the lock

If your key is not going into the lock or is getting stuck, the first thing you want to try is realigning the pins in the lock. To do this, insert your key into the lock and turn it clockwise. As you turn the key, apply pressure to it with your thumb. This will help to push the pins up and align them correctly. If this does not work, you may need to use a pin straightener tool.
