This is the most technical phase. A diagnostic tool is connected to the car's OBD-II port. For newer Audi A4s, the locksmith or dealer should link to Audi's "FAZIT" database in Germany to license the brand-new key and "present" it to the car's immobilizer system.

4. Setting Up Remote Functions

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