After choosing a deadbolt that complements your design style and provides the level of safety needed, it's time to put in the new hardware. Installing deadbolts is very similar to installing door handlesets or handle locks, except that a dead bolt is installed higher up on the door. One crucial thing to take your time doing is the marking your drill holes, as you don't want to mess up your door.
Step 1: Mark up a dead bolt template using the one included by the manufacturer with your dead bolt or make your own. The important thing is that your hole in the door face and the hole on the door edge match up correctly. It's always a good idea to double-check your measurements.
Step 2: Drill holes in the door, following any instructions provided by the dead bolt manufacturer. Usually, you want to drill the door face holes first, and then drill the latch hole. You may need a spade drill bit and a hole saw to cut a clean, smooth hole.
Step 3: It is now time to installing your dead bolt lock and the latch plate. If done correctly, the dead bolt will slide easily into the latch plate providing more security for your home.
