A lot of people commonly think that installing a new deadbolt is a tough job. It generally isn’t nearly as hard as people think. Typically when you replace a lock the existing holes in the door match up with what you need for you new deadbolt.
Before we get started and you buy a new lock make sure that you check to see that it will cover the entire hole in the door left by the old lock. You don’t want it to be a bit smaller and show some of the old hole that was drilled there. This is not very likely as most doors have a standard size hole drilled but better safe then sorry.
Now on the back of the lock on the inside of your door you will see two screws just like in the photo to the right. These screws anchor the front and back together pinching the lock on the door. Take out these two screws and and you can pull the front and back of the lock off of the door. Make sure that you hold the front of the lock or it might fall to the floor damaging something.
The next step is to take the bolt out of the door. The picture to the left is what the bolt looks like so just pop that out of the hole that its in.
So far so good and you basically just repeat the steps backwards and the new deadbolt will go right in. So take the new bolt and insert it right side up into the hole that you just took the last one out of. Once this is in place take the front and back of the lock and place them together on the door. There will be a flat plate the goes through the bolt from the front face of the lock. That is what turns the bolt in or out when you insert a key or turn the thumb turn. The thumb turn, like you see in the first picture, is on the inside obviously with the key hole or keypad facing the outside. Now insert the two screws and tighten the lock to the door.
The last thing you have to do is replace the strike plate to match the one from your new lock. It will either have 2 or 4 screws with it. The two longer ones, if you have them, are to anchor the plate. They reach deap into the door so if it gets kicked it will be much harder to knock the door open. The other two are on all plates. they just hold the strike plate in place. Once you have screwed these in you should be ready to go!
