Electronic security system |
| abstract |
An electronic security system includes an electronic lock mechanism (201) and an electronic key (101 and 104), each of which is provided with a microprocessor controller (501) and a memory (502) storing data including an ID code. The lock microprocessor (601) changes the ID code stored in its memory (602) upon the operation of the lock by a correct key. The key (101) can only be used to operate the lock once, and thereafter must be reprogrammed by a host computer with the updated ID code for the lock. The electronic lock operates a solenoid (209) which retracts a bolt blocking mechanism (210) which prevents the unlocking of the bolt (202) even when a key having the correct mechanical key cuts (102) inserted into the lock. Power for operating the electronic lock as well as the solenoid is provided by a power supply within the key (504). |
