Abstract

The invention is directed at an electronic lock assembly which is operable by a suitably programmed electronic key. The electronic lock assembly includes a cylinder type locking mechanism, where a solenoid and plunger is provided to electronically lock and unlock a key cylinder, thereby selectively allowing rotation of the key cylinder for operation of the locking mechanism. To prevent rotation of the key cylinder and loading of the solenoid plunger prior to the solenoid receiving an authorized signal to retract the plunger, a stop mechanism is provided which only allows rotation of the key cylinder in predetermined coordination with operation of the solenoid.
