<p>The door locking system (1) includes an electronic key (2) and a lock (3) with a rotary element (30, 9) that can be disengaged by an opening relay (4) to actuate a latch (31) in the lock; the rotary element (30, 9) is provided to drive a dynamo (5) that transforms its rotating movement into electricity to charge a related battery (50) that supplies a working voltage to the relay (4) and enables the actuation of the latch (31). A CPU (6) with a related memory (60) is provided to store opening codes intended to control operation of the relay (4); and the escutcheon of the lock (32) has a USB port (7) connected to the CPU. The electronic key (2) has a part (20) with USB mass storage means to store codes for opening the lock and when inserted in the USB port (7), read and compared with the authorized codes stored in the memory (60) of the CPU (6), if there is a match with an authorized opening code, said CPU operates the relay (4) to disengage the rotary element (30, 9), which can rotate generating the electricity for said opening relay and release the latch (31), which can then be actuated to open the door.</p> |
