Apparatus and method for preventing un-authorized starting of a vehicle

摘要

A theft prevention device, having a first switch capable of movement between a first position and a second position, the first position electrically connecting an electrical system to a power supply of a vehicle and the device includes a switch bypass circuit being electrically connected to said power supply when the switch is in the second position, the switch bypass circuit allows a current from the power supply to reach the electrical system, this current is less than the current traveling through the switch when the switch is in the first position, the current is sufficiently large enough to maintain volatile memories of electrical components in a vehicle.
