Things You'll Need
Small flat-head screwdriver
Deadbolt locks come in a variety of styles and finishes. Some deadbolts include a rose plate that adds a decorative touch to your hardware. This rose plate also serves to cover the mounting screws so that they aren't visible. If you have a need to remove a deadbolt from your door and can't seem to locate the mounting screws, chances are that you need to remove the decorative rose plate. Fortunately, rose plate removal is fairly easy and will only add a few moments to your deadbolt removal time.
Video of the Day
Position yourself in front of the deadbolt chassis on the inside part of your door. You will see the thumb-turn latch on the inside and a key cylinder on the outside.
Remove the thumb-turn latch in order to facilitate rose plate removal. Look on the shaft that connects the thumb-turn latch to the inside chassis. Locate the small pin-hole on the shaft. Use a paperclip or an awl with a fine point to press the pin-hole to release the lever. Remove the thumb-turn lever and set it aside.
Examine the rose plate that covers the inside chassis and locate a small notch along the rim. Use a small flat-blade screwdriver to gently pry the rose plate off of the chassis. Remove the rose plate and set it aside. The mounting screws should be visible.
Unscrew the two mounting screws with your Phillips-head screwdriver. Remove both screws and set them aside. Grasp the inside chassis with one hand and the outside chassis with your other hand. Pull the two halves of the deadbolt apart and set them aside.
Open the door so that you can view the edge of the door. Locate the two screws that secure the latch mechanism in place. Remove the two screws with your screwdriver and slide the latch out of the edge of the door. Set all pieces aside and keep all components together to make reinstallation easier.
Take the deadbolt to your local home-improvement center and have it re-keyed, or replace it with new hardware.
If you decide to replace the deadbolt, consider donating the old deadbolt to Habitat for Humanity's Restore program. Door hardware can be reused by those in need.
