This code is in line with the unique digital serial numbers of the computer of the car. This stops unauthorised attempts to start the car as only the proper keys will be able to do so.

This technology is believed to be more secure than conventional car keys because it makes it harder for a thief to "hot wire" an automobile and get it started.
