1. A lock core, comprising:
a shell;
a plug positioned within and rotatable relative to the shell between a first position and a second position about a longitudinal axis of the plug;
a lock, the lock having a first locked position preventing rotation of the plug relative to the shell, an unlocked position allowing rotation of the plug relative to the shell and a second locked position different from the first locked position preventing rotation of the plug relative to the shell, the lock moveable from the first locked position preventing rotation of the plug relative to the shell to the unlocked position with a first movement of the lock, the first movement having a vector component along the longitudinal axis of the plug and a vector component along an axis transverse to the longitudinal axis of the plug; and
an actuator configured to engage the lock, wherein engagement of the actuator to the lock causes progressive motion of the lock from the first locked position, then to the unlocked position, and then to the second locked position;
wherein the shell comprises a lock receiver, in the first locked position a first end of the lock extends into the lock receiver, in the unlocked position the lock does not extend into the lock receiver, and in the second locked position a second end of the lock extends into the lock receiver.
