Deadbolts are a simple way to add extra home security to your entry doors. Occasionally, you may want to re-key the deadbolt or change out the deadbolts for matching units. Replacing a deadbolt requires removing the existing deadbolt from the door. All deadbolts secure to the door with two screws from the inside. However, some deadbolts hide the screws behind covers. Removing a deadbolt with no visible screws requires removing the cover that is hiding them.
Unlock the deadbolt using the key or thumb lever. Look for a small hole on the neck of the thumb lever between the back of the lever and the face of the deadbolt, if a thumb lever exists on the inside.
Straighten a large paper clip, and stick the end of the paper clip into the hole. Pull the thumb lever away from the lock as you depress the small spring inside the hole with the paper clip.
Look for a notch on the cover plate between the plate and the door. If you have a key cylinder on the inside, look for a small notch between the top edge of the deadbolt. Insert a small flathead screwdriver or the corner of a rigid putty knife into the notch to pry the cover off. Removing the cover reveals the attaching screws.
Remove the two screws that secure both halves of the deadbolt lock to the door with a Phillips-head screwdriver. Pull the two halves off of the door.
Turn the screws securing the latch bolt plate to the edge of the door counter-clockwise with a Phillips-head screwdriver. Pry the latch plate from the door edge with the flathead screwdriver, and pull the entire latch bolt assembly out of the door.
Some screws are covered by small hole covers that resemble pin heads rather than a complete cover plate. Remove the covers with a putty knife and access the screws.
