<p>System for blocking/opening a lock, this keyhole or double sided safe key lock being of the variety housing the corresponding locking device, operable by means of an opening and closing key, which comprises a locking device (4) blocking means (5) and a printed circuit board (7) with a storage and remote data recovery means, linked to the locking device (4) blocking means (5) with an assigned identification code, as well as an energy source (6), such as a battery and, a chip (10) built into the opening key (9) in which the identification code is stored and stored in the memory of the printed circuit board (7), in such a way that when the lock (4) is in "closed" position, it is secured by the blocking means (5), this blocking means (5) becoming unblocked when the key (9) is introduced into the "eye" (16) of the lock (1) the chip (10) transmitting its identification code to the printed circuit board (7) by means of radiofrequency, to be compared with the code stored in the circuit board memory.</p> |
