How to Install a Deadbolt

Installing a deadbolt can upgrade the security of your home significantly. Deadbolts are much harder to break or pick and they give you an extra locking point when it comes to the safety of your door. You can hire a professional to do this project or you can take it on yourself.


There are a number of things you should do to properly install a deadbolt. You want to make sure you follow the steps in order to get the deadbolt placed securely.

    You should also consider the strength of your door as your deadbolt is only as good as the material it is attached to.
  1. 1.Choose the Placement on the Door

    First you want to choose where exactly on the door you want the lock to be. It needs to be at a comfortable height, but you may want to put it high on the door to keep it away from children.

  2. 2.Use the Template to Cut the Holes

    Your deadbolt will come with a template that marks exactly how big you need to cut the hole. Place the template center on the edge of the door at the height where you want to put the lock. Make your marks and then drill the holes, both the front hole and the side hole for the locking mechanism.

  3. 3.Place the Latchbolt Faceplate Flush with the Door

    The latchbolt faceplate is the next important step because if it is not flush the door will not open and close properly. You can always sand down a bit of the wood to make it move in and out more easily.

  5. 4.Lubricate the Moving Parts

    Before you install the lock you should lubricate all the moving parts. This ensures that the lock will smoothly move with the key and should keep it from jamming or breaking the key in the future.

  6. 5.Fasten the Key Portion of the Lock

    When you are fastening the actual key part of the lock, ensure that you place the screws on the inside of the door. If the screws are on the outside, someone could disassemble the lock in order to gain entrance into your home or the building.


    These steps walk you through the basic process of installing a deadbolt. You can always consult a locksmith who can guarantee his work. You should also consider the strength of your door as your deadbolt is only as good as the material it is attached to.
