The Key Selection

The appropriate key blade or fob must be matched to the automobile's VIN. Even within the exact same model year, Audi may have utilized different frequencies (315MHz vs. 433MHz). Utilizing the incorrect frequency will result in a key that might begin the car but won't run the remote locks.

The Programming/Coding Phase

This is the most vital step. A technician links a diagnostic computer to the Audi's OBD-II port. The vehicle is taken into "discover 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 tempting to purchase a ₤ 30 key fob from a generic online marketplace, Audi A4 owners need to exercise caution for the following factors:
