Abstract: Systems and methods for theft deterrence of a vehicle are provided. Each of two or more immobilization point devices generate a random number and broadcasts it to all of the other immobilization points devices. Each of the immobilization point devices retains a local copy of its own random number and concatenates the local copy of its own random number with the random numbers of the other of the two or more immobilization point devices from the bus. From the random numbers broadcast on the bus, all of the random numbers are concatenated in a predetermined sequence to form a single challenge, which is transmitted to a remote transponder. Each of the immobilization point devices then compares a single response from the transponder to their local concatenation. When a specific portion of the response from the transponder matches a local concatenation, then enabling the function of the immobilization point device.
