4. Pin Code Retrieval: Many producers (such as Volkswagen, Audi, and Ford) need a specific “Passphrase” or PIN to access the security module.
5. New Key Sync: The brand-new transponder chip is positioned near the ignition or a designated “sweet area,” and the software application composes the vehicle’s distinct ID to the chip.
