Abstract

An electronic lock assembly is actuated by a key including a transponder. The key is received within a coil assembly of the lock assembly. The key engages a switch that powers the coil assembly. The coil assembly generates a magnetic field that energizes the transponder. The transponder transmits a signal received by a controller. The controller actuates the lock assembly responsive to the received signal to move a locking member to an unlocked position. The key may then move to unlatch a latch associated with the lock assembly. As the key provides the energy required for unlatching the latch further energization of the motor is not required. The lock assembly provides for the actuation and energization of the transponder with small amounts electrical energy such that the lock assembly may be powered by commercially available batteries for a practical operational life.
