Abstract
A recodeable lock includes a housing, a cylinder plug, a plurality of wafer tumblers, and a sidebar coupled with the cylinder plug. The sidebar is assembled with a plurality of code blocks and a codebar releasably securing the code blocks to the sidebar. A liftbar is disposed in the housing radially outward of the cylinder plug and is configured to selectively engage a radially outward extending appendage of the codebar when the cylinder plug and sidebar are rotated to a recoding orientation, to release the code blocks from the sidebar. The housing includes a circumferential track axially positioned to receive the appendage of the codebar to permit greater than 180 degree rotation of the cylinder plug and sidebar with respect to the housing.
