Good basic advice, better than from the "kid at the hardware store"

How to Choose a Deadbolt Lock

Hi! I'm Daniel on behalf of Expert Village and this section we are going to be talking about the differences between deadbolts and choosing a deadbolt for your installation. There are two kinds of deadbolts that you want to look at. There is a single cylinder and a double cylinder. Most of your regulations in this country are going to require a single cylinder which has a key on the outside and a thumb turn on the inside. This is strictly for fire safety. You wouldn't want to get locked in your home and not be able to get out if there is a fire or another emergency. However if you do have a window or glass right next to where someone could break it and simply reach in, then you can put in a double cylinder deadbolt which is key bolt on the inside and out. You want to check regulations in your area to make sure that you are not violating fire code. If you do choose to use a double cylinder deadbolt, we recommend that you leave a key in it whenever someone is home and only take it out if you are going to go on a long or extended vacation. The other thing that you want to look at when choosing your deadbolt is the type of latch that you are going to be putting in. If there is already a deadbolt or if you are replacing a old one or you want to make a quicker one, then the new one you want to go in with a drive in latch. This latch here is a one inch throw but its just a punch in. All you have to do is drill a one inch hole and just push it right in and that is what secures it. If it has already been mortised out, then you want to get one that has a standard mortise that is already build on to it. Some of the deadbolts that you find out there could be converted one way or the other but that is one of the things that you would want to check once you are using a deadbolt.
