To uninstall your existing lock please refer to your lock brand's user manual.
Here is the general information on how to uninstall common deadbolt door locks:
- Remove the screws of the deadbolt. The face of your deadlock on the inside of your home should have screws on it. Remove these screws with a screwdriver.
- Pull out the interior faceplate. Once the screws have been removed, the faceplate can be pulled out. Generally, you can pull it straight out, though in some cases you might need to twist the faceplate counter clockwise before pulling it out.
- Remove the exterior faceplate. Once the interior faceplate has been removed, the faceplate on the outside of your door can also be pulled out. You will probably need to twist it counter-clockwise before pulling it out.
- Sometimes there will be screws in the exterior faceplate as well. If so, unscrew these as well, before attempting to pull it out.
4.Unscrew the set plate. The set plate is the piece of metal that faces the doorframe and connects the bolt to the door frame. It is the part of the lock visible on the side of the door. There should be a screw on the top and the bottom of the set plate. Remove both screws.
5.Pull out the set plate and bolt. The bolt is the piece of metal in the center of the deadbolt that, when locked, fits into the jamb hole in the doorframe to hold your door closed. It is usually attached to the set plate so that once the set plate is unscrewed, both can simply be pulled out.
- In some cases, the set plate and bolt are not one piece. If so, once the set plate is removed you can pull out the bolt separately.
- If you did not unlock your deadbolt prior to removal, you can still remove the bolt. Just look for where the bolt connects to the locking mechanism and use a screwdriver to twist it open.
