Certain vehicles come with electronic immobilizers that protect against theft by stopping the engine from starting without the correct key or fob. The system checks to determine if the key or fob is digitally signed. The system will shut off when it isn't. This kind of system has been proven to be effective in reducing automobile theft and is now required for many models of cars by the manufacturer.

In some instances the modules require specific keys that are designed by an expert to work with the anti-theft system. This is usually performed by a dealership or locksmith via computers.
