An electronic antitheft device comprises a keyboard for producing coded signals which are sent to a memory where they are compared with stored signals, a successful comparison causing the generation of signals which permit the application of the supply to one or more circuits, e.g. for enabling electric, electromechanic or electropneumatic members and mechanisms such as motors, doors, and vehicle doors, bonnets and trunk racks, provided with suitable servocontrols. <IMAGE> |
