How do I install a deadbolt lock on an exterior door?
Lay OutPlace the lock template on the door to create reference points for the cylinder and the deadbolt latch. Mark the centers of the holes needed for these components with an awl.Drill HolesDrill the large diameter hole necessary to accommodate the cylinder by using the proper size hole saw equipped with a pilot drill bit. Drill through the face of the door until the pilot drill bit emerges on the opposite door face. Finish drilling the hole from the opposite side. Drill a hole for the deadbolt on the edge of the door using a spade bit.Install HardwareSlide the deadbolt into place, and use a utility knife to mark the outline of the dead bolt plate. Chisel out the material inside the marks so the plate sits flush with the edge of the door. Install the two mating cylinder sections, one outside and one inside. Mark the edge of the bolt with a felt tip marker or lipstick, and throw the bolt with some pressure to mark a reference point in the door frame.
