How to Install a Door Deadbolt
Installation of a Deadbolt
What we have here is an entry-level set and a deadbolt. We have the lever set with a thumb turn and lock. This will obviously go on the outside, this will go on the inside, and locking deadbolt inside and outside. Single-sided so it only takes a key on one side. And we're going to install it in this practice door. OK, so now we're going to install the deadbolt. Most of them are indicated with a stamp on it telling it which side goes up so that the actuator aligns with where the tail piece is from the deadbolt. This one tells us this side is up. So we'll insert that into the opening. We can see that centered. Depending upon how deep the hole is in the door a lot of these are adjustable. So if that's an adjustable one and you see this is crowded over a little bit you'll want to expand it. If it hits the wood here then it probably needs to be shortened. This one's already preset for the right size. And of course the locking part goes on the outside. What we're going to do is we know that when the key is turned we want the deadbolt to come this direction. Typically the top of the key way moves in the direction that you want the bolt to go, so in this is instance we want to turn this tail piece as far toward the unlocked position as we can. This is wider than it is tall or taller than it is wide in either case we know it has to go into the actuator with this orientation. So we'll turn it all the way this way and then just back far enough to come through that slot. And we'll take our thumb turn and we'll align it with that actuator. And install the screws.
