Abstract
A shell and core interchangeable lock assembly for use in a shell housing. The core includes a rotatable pin plug and the shell includes a substantially cylindrical body with a pin chest therein. A mechanism which captures the shell and core within the shell housing includes an integral retainer ring and lug which is attached to the core. The mechanism allows rapid insertion and removal of the shell and core by the use of a correctly bitted control key. The mechanism additionally has a sub-mechanism for preventing its operation by accident or by tampering without the appropriate control key.
