Abstract:
A cylindrical lock and key set with an electronic interlock circuit includes a self-destruct circuit portion which is intercepted, engaged and destructed by an intercept member when the cylinder is forcibly, axially removed from the lock sleeve. A second intercept member may engage the circuit and destruct it when the cylinder is forcibly rotated. Either or both of the intercept members may be located on the cylinder.
