Abstract: A lock assembly includes a lock housing with an annular wall separating an end wall and a face. A core is received in an opening disposed in the face. The core defines a keyway disposed in rotational engagement with an end portion for actuating the lock assembly between locked and unlocked positions. A drive member is rotationally interconnected with the end wall of the housing. The drive member is disposed in driven engagement with the end portion of the core. An adapter defines a generally X-shaped slot and is fixedly attached to the end portion. A tail piece is received by the slot. The tail piece defines an elongated substantially flat appendage including a proximal end retained in the adapter and a distal end extending outwardly from the adapter. The proximal end is twisted relative to the distal end between generally 40 and 50 degrees.

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.
