    • A lock mechanism is mounted in a housing in which a latch bolt is guidingly retained and having an engageable end spring biased outwardly of a side wall of the housing. A bolt retracting mechanism is secured to a spindle adapted to retract the free end of the bolt within the housing. A driver hub is connected to the spindle and a motor driven clutch mechanism is provided for interconnecting the driver hub to a driven hub adapted to retract the bolt when the clutch mechanism is actuated to a bolt retracting position. When the clutch mechanism is actuated to a bolt engaged position it disconnects the driven hub from the driver hub. The clutch mechanism has an articulated spring biased linkage to permit the clutch to move to the bolt retracting position regardless of the position of the driver hub which is connected to the spindle which is rotatable by the lock handle, or to move to the bolt engaged position regardless of the position of the driver hub.

    • -11- An electronic door lock is programmable to accept new valid data key devices using a special data key device from with a set of special data key devices used for programming and control purposes. The lock has a learn mode controller responsive to a learn data key device to enter into a new valid access data key learn mode. A valid access code recorder is responsive to a first previously unknown code contained in a first new data key device while in the learn mode to record the first unknown code as a valid access code for operating said lock. A cancel code recorder is responsive to a second previously unknown code contained in a second new data key device while in the learn mode to record the second unknown code as a cancel code paired with the valid access code of the first new data key device. In use, the loc k is activated to open in response to the valid access code of the first new data key device, and is activated to cancel the recorded valid access code in response to the cancel code of said second data key device. The lock is able to operate with any data key device without requiring preprogramming specifi c to the lock. Programming and control is made easier by hierarchical distinct ly labeled special data key devices used for specific corresponding programming and control purposes.
