The antitheft device includes a power supply, an ignition device for starting the vehicle\s engine, an ignition switch having a switch mechanism for opening and closing a power circuit between the power supply and ignition device and an antitheft unit. The ignition switch includes a mechanical locking mechanism for selectively preventing the normal steering operation of the vehicle as well as sensors for detecting the removal or destruction of the switch mechanism or the mechanical locking mechanism. The antitheft unit causes a first disablement condition in response to an input signal where at least a part of the ignition device is disabled and causes a second disablement condition in response to the detection of an abnormality by the sensors where at least a part of the ignition device is disabled. The ignition device being incorporated into the antitheft unit.
