Fahrzeugdiebstahlsicherung

摘要

A key for storing a predetermined electronic code is provided independently from a vehicle, and a mechanism is provided for comparing the electronic code in the key with a built-in stored electronic code after an ignition switch is switched from an OFF position to an ON position. 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.
