<p>A lock control system of the type comprising lock operating means governed by an electrical actuator (6) controlled by an electronic circuit incorporating a receiver (HF2) for encoded radio-frequency signals emitted by a portable transmitter (HF1) comprises a first microprocessor (IC6) activated by a second microprocessor (IC9) programmed to decode and compare the encoded radio-frequency signal and to activate said first microprocessor on recognizing said encoded signal, said first microprocessor, once activated, being arranged to process data received from magnetic sensors (7,8) sensing when the lock is completely unlocked and completely locked and to cause the electrical actuator to operate in one direction or the other. <IMAGE> <IMAGE></p> |
