Abstract

See full text

A vehicle antitheft device includes a first electric device signal detection circuit for detecting a first signal generated by the operational state of a first electric device and a second electric device signal detection circuit for detecting a second signal generated by the operational state of a second electric device. The first and second signals are combined to provide an input code. When the input code matches with a predetermined first ID authentication code, start-up of an engine of the vehicle is permitted. Accordingly, the vehicle antitheft device provides an increased number of codes for enabling or disabling an immobilizer function of the vehicle antitheft device, thereby effectively preventing theft of the vehicle.
