Immobilizer

If the codes do not match, the ECU will not activate your fuel supply system or spark plugs, preventing your engine from starting.

You can then utilize the information you've obtained to gain access to CAN bus which is the vehicle's internal communication system. Once you have access to the CAN bus, you are able to look up the messages that the components of the immobilizer exchange, and deactivate the engine control module (BCM) or the body control module.
