Abstract
An anti-theft device for an automobile with high reliability is proposed. The device detects an intrusion and a battery disconnection and disables the engine. The device is powered by a battery prepared exclusively for the device besides the main battery of the automobile. The battery is mounted on the same board as the device, therefore increasing the reliability of that device. The device is simple to operate. When the driver leaves the car and the doors are locked, the anti-theft device is activated. No additional operation is required from the driver. The anti-theft device is even more reliable with the use of a key which has a bar-code printed on its surface.
