The correct key blade or fob should be matched to the vehicle's VIN. Even within the exact same model year, Audi might have used different frequencies (315MHz vs. 433MHz). Using the wrong frequency will result in a key that may start the car but won't operate the remote locks.

The Programming/Coding Phase

This is the most critical action. A specialist links a diagnostic computer to the Audi's OBD-II port. The automobile is put into "learn 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
