  • Vehicle anti-theft device
    Patent number: 5861816

When the electronic codes do not correspond, the vehicle is prevented from starting, and it is prevented from starting even when the electronic codes do correspond if the number of non-correspondences reaches a predetermined value. In this way, the vehicle is prevented from starting when the electronic codes match by chance when unauthorized start-ups are attempted.
