Abstract
A rekeyable lock cylinder with a cylinder body, an inner sleeve, and a plug assembly is provided. The plug assembly includes a plurality of key followers and a corresponding plurality of first racks and second racks disposed in carriers. The first racks correspond to operation of a user key and the second racks correspond to operation of a master key. As such, the lock cylinder is usable in a user/master key system. Disengaging either of the first or second racks from the key followers allows rekeying of the lock cylinder for the user key or the master key.
