Abstract

The present invention is directed at an electronic lock assembly which uses a simplified locking mechanism, which is operable by a suitably programmed electronic key. The invention is directed to a cylinder type locking mechanism wherein a solenoid and plunger is provided to electronically lock and unlock a key cylinder, thereby allowing rotation of the key cylinder for unlocking of a locking mechanism when a suitably programmed electronic key is used in connection with the mechanism. A side bar and retaining spring engage the cylinder plug to prevent rotation thereof in the locked position with the side bar contacted by the plunger of the solenoid to prevent the side bar from moving until an authorized key is used to unlock the mechanism.
