A cam assembly may be constructed with lock cylinder perforated by a centrally positioned keyway, and having an exposed circumferential surface surrounding the keyway rotatably fitted within a centrally positioned keyhole of a housing, and rotated within the centrally positioned keyhole in response to rotational force applied by a key conformingly corresponding to the lock cylinder through an arc. An electronic circuit containing a memory and a microprocessor, is mounted upon and supported by the cam to rotate with the cam through the arc, operationally responds to digital data carried by the key that is in electronic conformance to data stored within the memory, by electrically energizing a release mechanism that is spaced-apart from the axis of rotation of the cylinder plug, to move from a deployed position preventing rotation of the cam relative to the housing.
