Cylinder lock and key assembly

Abstract

A cylinder lock and key assembly for effecting a mechanical and/or electromechanical locking with recodable tumbler devices and devices which influence or generate electrical currents is provided. The assembly includes a key, a cylinder housing, a lock cylinder and a keyway disposed in the flat rib of the lock cylinder housing which receives the rotatable cylinder. The key and the keyway are provided with cooperating, exchangeable and codeable mechanical devices, e.g., pins, for a mechanical locking and devices which generate or influence electrical currents, e.g., resistors, inductors, capacities or semiconductors, for effecting an electromechanical arresting or other signal triggering.
