Even for keyless start models, a physical "emergency blade" should be cut. This is done utilizing a high-precision laser cutter. For Audi, this is typically a "sidewinder" or "laser-cut" key, which includes a serpentine groove cut into the center of the blade instead of notches on the edges.

3. Setting the Transponder

This is the most technical stage. A diagnostic tool is linked to the car's OBD-II port. For more recent Audi A4s, the locksmith professional or dealership must connect to Audi's "FAZIT" database in Germany to authorize the new key and "introduce" it to the car's immobilizer system.

4. Setting Up Remote Functions

Once the engine is successfully starting with the new key, the specialist will configure the remote buttons for the locks, alarm, and trunk.
