Claims
- 1. A lock and key assembly comprising a front body, a rear body and a key,
the front body containing a printed circuit board, a battery electrically connected to the printed circuit board, a lock radio frequency antenna operatively connected to the printed circuit board, and a window in front of the lock radio frequency antenna, the rear body having a first cavity which rotatably receives a plug such that the plug is operatively connected to a cam, and the cam interacts with hardware in a door for locking and unlocking the door, the key comprising a passive radio frequency identification device, a key radio frequency antenna, and a key blade, the plug having a key slot for receipt of the key blade such that when the key blade is inserted into the key slot the distance between the lock radio frequency antenna and the key radio frequency antenna is sufficiently small to permit communication, the rear body having a second cavity housing a motor and a blocker, the motor being electrically connected to the printed circuit board such that when power is provided to the motor, the motor rotates the blocker from a locked position to an unlocked position, and wherein when the blocker is in the locked position the blocker prevents displacement of a sidelock pin from a depression in the plug, and when the blocker is in the unlocked position the blocker does not prevent displacement of the sidelock pin from the depression.
- 2. The lock and key assembly of claim 1 further comprising an external jumper contact for providing electrical power to components in the assembly which use electrical power.
- 3. The lock and key assembly of claim 2 further comprising an LED electrically connected to the printed circuit board, the LED operating to communicate to the keybearer whether access is granted or denied by the lock assembly.
