Storm door handles provide ease when opening storm doors, but they should also be reinforced with deadbolt locks to ensure maximum security for the home. A deadbolt lock is a safety device that keeps intruders at bay. Installing a deadbolt lock in addition to storm door handles is quite easy, but it does require proper hand-and-eye coordination and proper tools. Here’s how.


If there is a pre-bored hole for the deadbolt lock, simply uninstall the old lock if any, and proceed with the installation properly. If not, proceed with these steps. Deadbolt locks should be installed at least 6 inches above storm door handles.

Cut the Necessary Holes

On the lockset template, set the backset for the deadbolt lock. The backset is the distance from the center of the hole to the edge of the door. This distance is typically 2 ¾-inches or 2 3/8-inches. Align the template to a line 6 inches above the storm door handles. Drill two holes for the screws and screw the template to the edge of the door before working with the deadbolt lock main hole. Use a 2 1/8-inch hole saw to drill the hole for the body of the lock. Make sure to drill only halfway through one side of the door to avoid splintering and finish the hole through the other side of the door. Use a 1-inch hole saw to drill a hole at the door edge for the deadbolt. Remove the template from the door. Proceed with the door jamb and drill a hole deep enough for the deadbolt to fit into.

Create Mortises for the Strike and the Faceplate

Slide the deadbolt into the hole drilled at the edge of the door. Trace around the edge of the deadbolt’s faceplate. Remove the deadbolt and chisel out the marked area about 1/8 of an inch deep to allow the faceplate to fit into it. Proceed with the hole on the doorjamb. Trace the strike on the door jamb, drill holes for the screws, and chisel out the marked area.

Installation Proper

Slide the deadbolt back into the deadbolt hole and screw the faceplate tightly. Retract the deadbolt first before inserting the keypad or key cylinder into the deadbolt body hole. This part of the deadbolt lock should be installed on the external side of the door. Insert the mounting plate on the inside part of the door. Install the screws and connect the cable and battery if the deadbolt lock is electrical. Attach the thumb and turn to finish the installation on the door. Move on to install the dust box into the door jamb. Install the screws before screwing the strike in place. Test the lock.
