Claim 0:
1. An interchangeable lock core for use with a lock device having a locked state and an unlocked state, the interchangeable lock core removable from an opening of the lock device with the aid of a tool, the interchangeable lock core comprising:
a lock core body having an exterior lock core body envelope, the lock core body including an upper lock core body section having a first cylindrical portion with a first maximum lateral extent, a lower lock core body section having a second cylindrical portion with a second maximum lateral extent, and a waist having a third maximum lateral extent, the third maximum lateral extent being less than the first maximum lateral extent and being less than the second maximum lateral extent;
a moveable plug positioned within the lower core body section, the moveable plug having a first position relative to the lock core body which corresponds to the lock device being in the locked state, and a second position relative to the lock core body, which corresponds to the lock device being in the unlocked state, the moveable plug being rotatable between the first position and the second position about a moveable plug axis;
an operator actuation assembly operable to selectively actuate the moveable plug, the operator actuation assembly moveably supported by the lock core body;
a core keeper moveably coupled to the lock core body, the core keeper positionable in a retain position, in which the core keeper extends beyond the exterior lock core body envelope to hold the lock core body in the opening of the lock device, and a remove position, in which the core keeper is retracted relative to the exterior lock core body envelope to permit removal of the lock core body from the opening of the lock device; and
an actuator adjustably supported relative to the lock core body, a position of the actuator relative to the lock core body being adjustable, the actuator having an allow position, allowing the core keeper to be actuated by the moveable plug from the retain position to the remove position and, a disallow position, in which the actuator does not allow the core keeper to be actuated by the moveable plug between the retain position and the remove position, the actuator having a tool receiver adapted to be engaged with the tool such that the tool adjusts the actuator between the allow position and the disallow position, the tool receiver positioned within an exterior operator actuation assembly envelope when viewed from a direction along the moveable plug axis;
wherein the operator actuation assembly includes a cover removeable from a remainder of the operator actuation assembly to provide access to the tool receiver of the actuator.
