ABSTRACT:
The invention contemplates a cylinder lock and associated flat-key configuration, the lock being virtually pick-proof and the key being virtually imitation-proof. These features arise from a particular employment of supplementary lateral ribs or cams on the key, of predetermined height and longitudinal location, coacting with a system of supplementary pins guided by transverse bores in the cylinder core, and one or more case pins of the conventional pin-tumbler components of the lock will dog the cylinder against key-operation beyond a limiting angle, should the supplementary rib or cam profile of the inserted key be incorrect.
