Abstract

A lock cylinder of a plate or wafer tumbler type. The cylinder (10) has a plurality of locking wafers (19) and a key slot (14). The locking wafer (19) includes a pair of legs (21) which define therebetween an open ended key receiving slot in the wafer. This open-ended key receiving slot aligns with a key receiving channel (15), being an extension of the key slot (14), which extends into or through the wall of the body (11) of the cylinder. As a result a key of greater depth than normally required to operate the wafer lock can be accommodated in the aligned key slots and key receiving channel. This permits common keying between wafer and pin tumbler locks to be achieved.
