The right key blade or fob must be matched to the vehicle's VIN. Even within the exact same model year, Audi might have utilized various frequencies (315MHz vs. 433MHz). Using the incorrect frequency will result in a key that may begin the car but will not operate the remote locks.

The Programming/Coding Phase

This is the most critical action. A professional connects a diagnostic computer to the Audi's OBD-II port. The automobile is taken into "find out mode." The computer then synchronizes the distinct ID of the new transponder chip with the car's Engine Control Unit (ECU) and Immobilizer module.

The Risks of DIY and "Cheap" Online Keys

While it is appealing to purchase a ₤ 30 key fob from a generic online marketplace, Audi A4 owners need to work out caution for the following reasons:
