PURPOSE:To prevent the theft for a car in the case when a driver gets off the car, setting an engine key on the car, by constituting the title device so that an engine starting circuit is turned OFF, when a door is opened once, and by prohibiting the start of the vehicle so far as a control circuit is not restored by inputting the registration No. afterwards. CONSTITUTION:When a driver opens a door for getting off a car, a door opening detection switch 1 is turned ON, and an FF1 is reversed through an INV1 in the first control circuit 3, and the output of an INV2 becomes L, and a relay RY1 is energized, and a contact point ry1 is turned OFF. In other words, an engine starting circuit is turned OFF. When an engine is restarted from this state, a password No. is inputted from a password No. Input means 4, and collated with the password No. in a password No. memory 5 by a collating means 6. When the both No.s accord, an accordance output is generated, and the FF2 is reversed, and the FF1 is reversed by the reset signal, and restoration is performed. Therefore, the engine starting circuit is closed, and an operation- enabled state is generated. |
