ABSTRACT:
An electronic interlock system for a tumblerless lock which utilizes radio frequency identification to enable system operation. The interlock system includes a reader which powers an antenna to generate an electromagnetic field which in turn energizes a small transponder mounted in the key. The transponder transmits a unique identification code back to the reader via the antenna where it is decoded, and if valid enables system operation, but if invalid prevents operation. The antenna is mounted at the forward end of the lock assembly. A unique key retention system and cylinder anti-rotation lock system is also disclosed.
