Abstract

Changing the locking mechanism in a U-lock, cable lock or other tie lock as often as desired is achieved without compromising the lock's resistance to physical damage. This function is achieved by an auxiliary sleeve that removably fits over the U-lock's crossbar or the cable lock's end bar. Either bar provides an aperture, which is too small to permit the locking mechanism to be picked or pried, but which is operatively positioned and sufficiently large to provide access for a key to the keyway of the locking mechanism.
