A vehicle immobilization system has an electronically controlled locking mechanism which requires interconnection with an electrical supply for it to be switched between a locked state and an unlocked state. The locking mechanism remains in the state to which it is switched when disconnected from the electrical supply. The immobilization system includes control means which operates to connect the locking mechanism to the electrical supply to switch it from one state to the other, and to disconnect the locking mechanism from the electrical supply when the vehicle engine is running or the vehicle is moving. The immobilization system also includes means to prevent cranking of the engine when the locking mechanism is in it'"'"'s locked state.
