Before You Begin

  • Step 1 : Remove existing lock and prepare door jamb

    Remove the existing hardware from the door and door jamb. The keyless lock has an oversized strike plate so enlarge the hole in the jamb. In most cases the manufacturer of the lock provides a drill guide designed to fit over your drill bit. Place the guide on the drill and use it to enlarge the standard 1-in. hole to 1-3/8-inches. Drill about halfway into the existing 1-in. hole in the door jamb, remove the drill guide bit and finish drilling the 1-3/8-in. diameter hole 1-in deep.

  • Step 2 : Install strike box on door jamb

    If the new strike plate is larger than the one removed, you must enlarge the mortise in the door jamb. Chisel out any excess wood so the strike box and strike plate can be mounted flush on the jamb. Install the oversized strike box and strike plate with the 3-in. wood screws provided. Drill a 9/64-in. diameter pilot hole at least of 2-1/2-in. deep for each screw.

  • Step 3 : Install deadbolt

    Most units have adjustable deadbolts to fit a 2 3/8 or 2 3/4- in. backset, the distance from the edge of the door to the center of the lock hole. Determine the backset of the door by measuring from the edge of the door to the center of the large hole. Adjust the deadbolt latch for a 2-3/4-in. backset position if required, by rotating 1/2 turn. Insert the deadbolt latch through the hole in edge of the door. Secure the latch with the wood screws provided.
