If you are having problems with your screen door lock, then you will need to know how to fix it. The lock on your screen door can develop a lot of problems, from simply sticking when you wish to release the lock to not securing the door properly, and even to not working. A broken screen door lock can be very annoying, and you may not be able to afford to repair it quickly without assistance. If you are sure that you can fix the lock yourself, without calling in a locksmith, then there are some basic steps which you can take to ensure that the lock is back to working order in a short while.

Step 1 - Check the Lock

The first thing that you should do is work out exactly what is wrong with the lock. You should look at the key hole in particular, and try and work out if there is anything preventing the lock from turning properly. Look for signs that there are insects in the hole, or that there has been damage caused by dirt, weather, or other problems. You may be able to see a thick layer of dirt or grease around the key hole, and this is a sign that the lock is simply dirty. As a first step, you should use a pin to poke through the key hole,  and try and clean out any debris. Test the lock again once you have done this.

Step 2 - Clean the Lock

If this still does not work, then another effort should be made to try and clean the lock of debris. Buy some graphite powder from your local hardware or home improvement store, and add some to the lock, either by inserting some on the handle of a spoon, or by wetting the key and then adding some powder. Insert the coated key into the lock and turn it in order to remove dirt from the lock.

Step 3 - Defrost the Lock

If the problems that you are having with the lock are occurring in winter, then the problem may be that it has become frosted over. You can easily release the locking mechanism using a hairdryer, simply warming the lock from the outside. This should allow the lock to return to normal in a few minutes. Keep the lock at normal temperatures to keep it working well. You should also try cooling down the lock in summer, as metal can move as it warms up.

Step 4 - Replace the Lock

If you are still having no joy with your lock, then you may be forced to replace it completely. Unscrew the lock from the door, and remove the locking mechanism. Clean the rest of the lock, and lubricate it with grease. Add the new locking mechanism, and then re-attach to the door. Once this is done, you should be able to work the lock as usual.
