Abstract

A re-keyable lock cylinder includes a plug body and a carrier sub-assembly disposed adjacent the plug body. The plug assembly includes a plurality of planar wafers and the carrier sub assembly includes a plurality of racks for engaging the wafers in a face-to-face teeth arrangement. The racks disengage from the wafers to separate the teeth in response to movement of the carrier such that the lock cylinder is in a re-keyable condition when the racks are disengaged from the wafers.
