Door locks get old and wear out, just like many other items in a home. They are used by every member of the family, day in and day out, for years on end. Locks handle that use and abuse very well, but eventually they will need to be replaced. Fortunately, they are easy to remove beforehand. Schlage door locks are designed for a very simple installation, and this simplicity carries over to their removal as well.
Unscrew the mounting bolts located on the interior side of the door lock. Remove them from the door lock when they have been completely loosened.
Pull the interior handle away from the exterior handle, and set the two handles aside.
Insert a screwdriver into one of the holes in the latch mechanism. Use the screwdriver to force the latch mechanism out the side of the door.
Remove the screws from the strike plate in the door jamb, and pull the strike plate away.
