The chip responds by sending a unique code your car's immobiliser. The car's computer checks the code in its memory with that from the transponder chip, and if they match, the engine will start.
If the immobiliser is able to detect an unauthorized transponder or key is being used it will shut down the engine and prevent any of its vital components from functioning.
