How to Fix a Door Lock

Problems with the Key

Before you panic about the lock, make sure that the issue is not with your key. If you have a duplicate or spare key, then try locking or unlocking your door with that. If the spare works, then go ahead and get rid of your old key which might be chipped, bent, or otherwise broken. Always go to a reputable locksmith when you need a key cut. A poorly cut key is going to give you trouble like this.

Another problem associated with the key is a broken key stuck in the lock. Grab some pliers, some needle-nose pliers if you have it, and try to grip and pull the key straight out. If you can't grip, then try sticking a stiff wire into the cam slot at the back of the cylinder to push the key out.

Jammed Lock

If the key is only going in part-way or if the key does go in but will not turn, then you may have a jammed or blocked lock. There may be dust or dirt in the cylinder. You can either spray dry lubricant into the keyway and insert the key to get the lubricant working. You can also try WD-40.

Locks can also jam or freeze shut if you live in a freezing cold area. If your door lock is frozen shut, then warm the key by placing it in a bowl of hot water and try inserting the key and turning it that way. You can also try dethawing the lock with a hairdryer if possible.

Door Knob Issues

If the alignment of the door latch is off or if the door knob is loose, then grab your screwdriver. If the latch is not catching, then close the door slowly and watch the latch and strike plate. Figure out the misalignment and realign the strike plate accordingly. For a loose door knob, hold the knob on the other side of the door and tighten the screws until snug.

If none of these is the issue then there might be problems with the lock itself. For sophisticated problems, you might want to call a professional locksmith lest the lock completely unravel.
