Abstract: A core assembly for use with a core housing of a lock assembly is defined by a bifurcated core body including interconnected first and second cylindrical members disposed in an abutting relationship. The bifurcated core body defines a first end received by an opening disposed in the core housing and a second end defining a substantially continuous surface. A slot is defined crosswise of the interconnected cylindrical members disposed between the first end and the second end of the interconnected cylindrical members. A catch is received in the slot defined by the bifurcated core body. The catch is biased outwardly from the slot for interlocking with the core housing irremovably securing the core body to the core housing.

Abstract: The present invention provides for a lock assembly for selectively locking and unlocking a door using a key. The lock assembly includes a housing with a core removably disposed in the housing. A first actuator is coupled to the housing for defining a first lock configuration with a second actuator coupled to the housing independently from the first actuator for defining a second lock configuration. The core includes a keyway for receiving the key and is rotatable within the core between a locked position and an unlocked position. A universal drive member is coupled to the keyway and movable with the keyway between the locked and unlocked positions with the universal drive member interchangeably receiving the first actuator and the second actuator while the keyway remains in the core for interchanging the lock assembly between the first lock configuration and the second lock configuration.
