1. An interchangeable lock core for use with a lock device having a locked state and an unlocked state, the lock device including an opening sized to receive the interchangeable lock core, the interchangeable lock core comprising:
a lock core body having an interior, the lock core body including an upper portion having a first maximum lateral extent, a lower portion having a second maximum lateral extent, and a waist portion 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, the lower portion, the upper portion, and the waist portion forming an envelope of the lock core body, the lock core body having a front end and a rear end opposite the front end, the front end including a front face;
a moveable plug positioned within the interior of the lock core body proximate the rear end of the lock core body, 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;
a core keeper moveably coupled to the lock core body, the core keeper being positionable in a retain position wherein the core keeper extends beyond the envelope of the lock core body to hold the lock core body in the opening of the lock device and a remove position wherein the core keeper is retracted towards the lock core body relative to the retain position;
an operator actuatable assembly supported by the lock core body, the operator actuatable assembly including a base extending into the interior of the lock core body and an operator actuatable input device positioned forward of the front end of the lock core body and supported by the base;
an electro-mechanical control system which in a first configuration operatively couples the operator actuatable input device of the operator actuatable assembly to the moveable plug and in a second configuration uncouples the operator actuatable input device of the operator actuatable assembly from the moveable plug; and
a retainer which couples the operator actuatable assembly to the lock core body at a position between the front face of the lock core body and the rear end of the lock core body.
