ABSTRACT:
An interchangeable lock core cylinder for use with a lock housing has a cylindrical body with a pin chest attached and parallel thereto, a rotatable key plug inserted within the cylindrical body, provision for capturing the core in the housing, and a mechanism within the key plug for selectively operating the capturing provision. This mechanism allows rapid insertion, removal, and replacement of lock core cylinders using an appropriate control key. When installed, the core cylinder is locked into engagement with the housing and has a positive latching provision so that it cannot be removed without use of the control key.
