A firearm enabling and disabling electronic system comprising a base unit (1) and a safety device (4) adapted to be incorporated into a firearm (7). Each of the base unit (1) and the safety device (4) has a transmitter and/or receiver (2, 5) adapted to exchange and process wireless command signals with each other. The safety device (4) has an actuating circuit (6) which is controlled by the transmitter and/or receiver (5) of the safety device (4) and is adapted to actuate a locking mechanism (8), wherein in the locking mechanism is operable to prevent a firearm from firing. The wireless command signal (9) is operable within a predetermined distance between the base unit (1) and the safety device (4) so that when the safety device (4) is located within the predetermined distance from the base unit (1), transmitters and/or receivers (2, 5) exchange the wireless command signal which causes the transmitter and/or receiver (5) of the safety device (4) to prompt the actuating circuit (6) to actuate the locking mechanism (8) thereby causing the locking mechanism (8) to assume a locking mode in which a firearm (7) is prevented from firing.
