Device and method for locking and controlling a weapon

A locking device for a firearm, the locking device comprising:

• a locking cartridge adapted to be inserted into a firing chamber of the firearm, the locking cartridge comprising a cartridge shaped housing and a locking mechanism located in the cartridge shaped housing and configurable between an unlocked state in which the locking mechanism is extractable from the firing chamber, and a locked state in which the locking mechanism is configured to be fastened within the firing chamber;
• an actuator configured for changing a state of the locking mechanism between the locked state and the unlocked state;
• and
• a controller in communication with the actuator, and configured to control the actuator according to a signal received from an input device;
• wherein at the unlocked state of the locking mechanism, the locking device is extractable from the firing chamber as one unit by using a cocking mechanism of the firearm;
• and
• wherein at the locked state of the locking mechanism, the locking device is configured to be fastened in the firing chamber also by using the cocking mechanism of the firearm.

A method for locking a firearm by a locking device including a locking cartridge comprising a cartridge shaped housing and a locking mechanism located in the cartridge shaped housing and configured for assuming an unlocked state and a locked state;

• an actuator adapted to change a state of the locking mechanism between the locked state and the unlocked state;
• and a controller in active communication with the actuator;
• said method comprising:
• inserting the locking cartridge into a firing chamber of the firearm;
• receiving a first signal from an input device at the controller to unlock the locking device;
• instructing the actuator by said controller to cause the locking mechanism to assume the unlocked state inside the firing chamber of the firearm, so that by using a cocking mechanism of the firearm, the locking device is extractable from the firing chamber as one unit;
• receiving a second signal from the input device at the controller to lock the locking device;
• and
• instructing the actuator by said controller to cause the locking mechanism to assume the locked state inside the firing chamber, so that by using the cocking mechanism of the firearm, the locking device is fastened in the firing chamber.
