I know people that has rewired some fundamental part of the car like the fuel pump or something like that. There is a combination of the car buttons that must be pressed to start the car, if not you may start it but the engine will stop after some minutes. It must be done by someone that knows electronics, but doesn't seem that dificult to implement(although probably expensive), and it's very hard to detect and avoid by thieves if done properly.
