Troubleshoot and fixing a sticky deadbolt

Locks are tricky sometimes. People who understand locks will try to resolve the problem themselves and then head to a locksmith, if not resolved. People with less knowledge are likely to consult with a professional. Although this is good, it can cost much more than the actual problem to be.

Usually a deadbolt that is sticky or not working, i.e., not turning properly can be fixed easily and you will learn to troubleshoot and fix it in this presentation.

Why we are here?

•When a deadlock is sticky or not working properly, then the first problem could be inside the cylinder, the area in which the key goes, and it can be stiff and difficult to turn while it gets worn. The other area can be the bolt or the door-jam, in which the bolt fits when closed.

• So, how to determine whether the problem is with the cylinder or with the door-jam?

So, lets say that you have determined that the problem is in the cylinder, where the key goes, that is the key does not work or does not operate the lock, then you have two things to consider. First of, try that the key might be really worn, so go find other keys to see if any of them works. If that does not work, it may be that the cylinder needs lubrication, and that too, dry lubrication like graphite. Do not use any oil for lubrication, it will make it worse.

Keep in mind that the graphete can be hard stained, so keep away from carpets and keep a towel handy. Put the graphete lubricant inside the cylinder, one or more times, to make sure that the lubricant does the job. Try the key and if it still doesn’t turn, then the cylinder is probably worn out and you need a new cylinder or deadbolt. The easiest way is to contact a local locksmith nearby to get this done while you wait. A new deadbolt may cost up to $15 to $25.

The First Possible Issue:

To get the deadbolt out, remove the screws in the back and take out the knob and cylinder from either side of the door. Install a new deadbolt or get in done by the local locksmith. Follow the process in reverse for installation

The Process:

Another thing that can cause the lock to go stiff and difficult to operate is the wear or damage in lock mechanism or the alignment of the deadbolt and the back plate. To determine this, loosen the screws in the back and try the lock, if it works then tighten the screws and you are good to go.

Just Another Turn:

The second problem can be the alignment of the bolt with the door jam in the frame. If that is the problem, then the bolt will probably rub with the frame and create difficulties in proper operation. To fix that, filing can be done, to make it basically a bigger hole. The plate is usually of soft metal so it can be filed easily.

The Second Possible Issue:

Another thing that could be interfering with the bolt, could be uneven pieces of wood behind the frame plate, sticking out and not trimmed properly. If this could be the problem, this could be fixed with a chisel or a razor knife.
