For transponder keys and remote head secrets, the authentication process happens when the key is inserted into the ignition cylinder or, in push-to-start systems, when the key is brought within variety of the dashboard-mounted antenna. The car's ECU sends a signal to the transponder chip, which responds with its unique identification code. Just after the ECU confirms this code does the lorry'simmobilizer system enable fuel delivery and engine ignition.
Keyless entry systems rely on comparable principles, utilizing rolling codes that alter with each use to prevent signal copying and unapproved duplication.
