What You'll Need
Replacement Parts

A deadbolt lock is a common sight in many homes, and they can provide proper security for a house. Nonetheless, if you find that your deadbolt lock is broken or malfunctioning, you may need to get a better lock, or you may be interested in repairing the original one to make sure that it doesn't end up broken again. If you want to repair the lock yourself, here are some hints and tips that you should try to make your repair project go well. This is not a complicated project, and should only take you a short amount of time.

Step 1 - Clean and Oil the Lock

Most problems with a modern lock can be attributed to a lack of care and maintenance, so the first thing that you need to do when trying to repair a deadbolt is to ensure that it is properly cleaned and greased. You should wipe the whole lock over with brass polish and an old rag, and remove any corrosion or rust that has occurred. If this does not help the situation, try applying a bit of oil to the lock itself. Drip some into the key hole and around the spring. This will solve the problem in many cases.

Step 2 -Unscrew the Lock

If you find that you still have problems you may need to start unscrewing the lock to get at the parts inside. Unscrew the nails that hold the lock frame together. The lock should fall apart fairly easily, although if your lock is corroded you may need to pry it open with the tip of your screwdriver. When this is done, look inside and make sure that all of the parts are in the correct positions.

Step 3 - Checking the Parts

Once you have ensured that all the parts are there, take an old sewing pin or similar similar and run it around the edge of each part. Sometimes corrosive slivers fall into the parts and prevent them from turning properly. Examine the whole lock this way, and scrape out any dirt that you find.

Step 4 - Replace the Spring

If the lock is broken, the most common culprit is a snapped spring. Lock springs can be bought at any local home improvements store, and you can replace one with another very easily. Remove the screws that hold the lock in place, pressing down on the lock with one hand to ensure that it does not spring up and hit you in the face. Remove the old spring and press the new one tightly together. Keep it pressed down until the spring is in position, and then release it gently. You can now tighten the screws that hold the spring in place.
