Remove Storm Door Lock

Steps for replacing the lock and hardware on a storm door step 1.
Remove storm door lock. Slip a straightened safety pin into small holes or use a flat screwdriver to press against a slot or depression. If any screws are exposed during this process remove them to release the lock and remove it from the door. Straighten a paper clip and insert it into the hole. Removal of the two types of locks is similar in many ways so here is a convenient step by step guide to show you how to remove the door lock from a storm door.
Loosen the set screw. Once the door is open operate the handle and turn the deadbolt. Remove the old handle and screen door latch unscrew both interior latch mounting screws pull the interior and exterior handles apart and remove the center spindle. Check for any pinholes or depressions in the handle or around the trim.
Regardless if the storm door lock is the type that uses a deadbolt or a keyed handle you will need to remove a pair of set screws that are located on the interior portion of the lock or the part of the lock that faces the interior of your home. To unjam the deadbolt remove the installation screws on the latch rail from the outside. Using an allen key loosen the set screw and remove the interior door handle. Once triggered the lever or lock trim can be removed from the door.
Assemble the new exterior handle according to the instructions on the packaging and slide the spindle. If either does not operate when the door is open the hardware needs to be replaced. Remove the closer of the storm door by carefully tapping with the hammer the pin closest to the door jamb. At this point the square tab on the spindle is aligned with the square.
Discard the old handle. Tapping out or pulling out the pin is best done with the door closed because when the pin is released the closer will spring back an action that is minimized when the door is closed. Step 1 remove the cylinders or handle assembly. Apply a bit of pressure to the paper clip to trigger a release button inside the hardware.
Some locks designed for interior use may have these holes on the exterior side for homeowners who have lost the key. Then use a phillips screwdriver or power screwdriver to take out the screws. Use the flat head screwdriver to turn the spindle in the center of the door lock cylinder counterclockwise until it stops.
