How to Repair a Stuck Storm Door Lock

A storm door lock that is stuck will reduce the door’s ability to keep your home safe and can result in damage during inclement weather. By knowing the steps to take to fix it, you can keep your storm door locks working effectively.

Step 1 – Examine Lock

The first step is to examine the storm door lock to determine the reason why it is sticking. The most common reasons are due to it becoming frozen in cold weather or because of a built up of dirt and grime.  

Step 2 – Heat Lock

To rectify the problem of a storm door lock that has become stuck because it is frozen, you will need to gently heat the area. Keep the key to hand and train the nozzle on one side of the lock for several minutes. Try the key to see if it turns. If it remains stuck, apply some heat to the other side of the lock and try again.

Step 3 – Clean Lock

A storm door lock that has become stuck due to dirt within it can be cleaned with graphite powder, which is available from hardware stores. Apply some of the powder to the lock or coat the key with it before inserting it, and turn the key.
