Abstract
A special type of key is made use of to actuate an electronically triggered release mechanism to unlock a door. To enable the electronic means to function, insertion of the key in the keyway initially closes a switch to energize the electronic circuit. Also when the key reaches the switch closing position, a read head for the electronic circuit, located adjacent the keyway, interprets magnetic coding carried by the key. The electronic circuit is programmed to motivate a motor driven mechanism to move a locking pin out of engagement with a latch bolt where the latch bolt has been acting to hold a door locked. Once the locking pin has been removed, the latch bolt is in fact withdrawn from its locked position by rotation of the key in a substantially normal fashion.
