A previously used lock assembly constructed for operation using a given key may be operated by a different key after rebroaching. Instead of requiring an expensive, complete replacement of a lock assembly and its operable keys, the present invention allows a lock assembly to be refitted for a different key by a relatively inexpensive replacement of its plug and at least one of the tumbler components, preferably the bottom pin only, of one or more preexisting sets of tumbler components, as needed to modify the lock to receive the different key.
