The system is designed to make it extremely difficult to steal a vehicle since the vehicle will only begin to start when it receives the proper signal from the right key. Key cloning devices can be used to duplicate keys, without having to re-programme the computer of the car to recognize the new key. Cloning keys to cars requires two things: A method of extracting the information from the original key, and a machine capable of writing the data onto an entirely new chip.

Advanced systems will have an identification feature that allows them to identify the different types of chips. automotive key programming prevents a key being programmed for a vehicle that is not the correct one and also protects against someone stealing a key and attempting to use it in another car.
