Tips on How to Fix a Sticking Door Lock

By Mark J. Donovan

In this video, Mark Donovan of shows how to repair a door lock with a sticky twist lock button and a key that won’t turn well in the keyhole.

Overtime and use a door lock can become difficult to turn a key in or the locking button hard to twist. Usually you can repair a door lock with an inexpensive tube of graphite lubricant, a screw driver and about 10 minutes of effort.

If the key does not turn well in the keyhole, simply shoot a few puffs of graphite lubricant into the keyhole and then insert the key and give it a couple of twists.

If the locking button or knob is difficult to turn then you will need to remove the back of the door knob from the door. Usually all you need is a screw driver to remove the screws that hold the door lock knob to the back of the door.

Once you have removed the door knob, apply graphite lubricant to all of the moving parts inside the door lock.

Then reattach the door handle to the door and try turning the door lock button. With any luck it will turn smoothly and easily. That’s all there is to it to repairing a door lock.
