The chip responds by sending a unique code your car's immobiliser. The car's computer compared the code in its memory with that from the transponder chip and when they match the engine will be able to start.

If the immobiliser is able to detect an unauthorised transponder, key or other device is in use, it will disable the engine and block any of its vital components from working.
