An interchangeable core assembly for a lock core assembly capable of being flush mounted in a door including a housing, a lock insert mounted in the housing, a lock core mounted in the housing adjacent to and cooperative with the lock insert, a thumb-turn assembly mounted in the non-cylindrical housing coaxial with the lock core, a first offset cam mounted on the thumb-turn assembly for rotation therewith, and a second offset cam mounted on the lock core for rotation therewith. The barrel of the lock core assembly is unobstructed by locking train components such that the lock core assembly extends completely through the latch assembly when installed therein. The lock core assembly is secured to the latch assembly without threads and a means to remove/replace the thumb-turn component is provided.

A door assembly is disclosed that includes a door and a cylinder dry lock assembly mounted to the door and including a cylinder lock, a thumb-turn lock, and an actuation mechanism interposing the cylinder lock and the thumb-turn lock. The actuation mechanism includes a first adapter matable with the cylinder lock and a second adapter matable with the thumb-turn lock and the first adapter. Actuation of the cylinder lock actuates the thumb-turn lock via the actuation mechanism.

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to retain position to permit removal.

An interchangeable lock core for use with a key and having a locked state and an unlocked state is disclosed. The lock core may include a shell, a plug, and a lock. The plug may be positioned within and rotatable relative to the shell between a first plug position and a second plug position about a longitudinal axis of the plug. The plug may include a keyway adapted to receive the key. The lock may be rotatable about a lock axis between a first wherein a rotation of the plug is restricted and a second position wherein the plug is rotatable from the first plug position to the second plug position. The lock axis may be positioned outside of an envelope of the plug.
