To install a deadbolt lock:
The deadbolt lock should be about 44 inches from the bottom of the door. Make adjustments if a storm door is used in conjunction so that the two locks do not interfere with each other. Use the template to properly position the lock
Mark the holes for the latchbolt and lock cylinder. This ensures that the two will line up.
Using a standard drill, bore a hole into the door for the lock cylinder. Using a spade bit, cut a round hold for the latch. Use a chisel and hammer to hollow out a 1/8 inch ridge on the edge of the door latch.
Screw the latchbolt faceplate flush with the edge of the door and insert the latchbolt and keyed portion into the hole. Line up the holes from the lock to the exterior and screw the interior and exterior portions securely together.
Close the door and mark where the latch meets the door jamb. Use a chisel to create a space for the strikeplate. Use the spade drill to bore a hole for the latchbolt to enter. Install the strikeplate.
Close the door and test the lock. Loosen screws and adjust as necessary until the lock fits snugly and easily passes to the hole.
