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.
