2. Integrated Fob Keys (B7 and B8 Platforms)
Starting around 2005, the Audi A4 approached a more integrated style. These secrets typically include a "dash-insertion" method where the whole fob is pushed into a slot to begin the engine. These make use of more complicated rolling code encryption.
3. Audi Advanced Key (Smart Keys)

This is the most technical phase. A diagnostic tool is linked to the car's OBD-II port. For newer Audi A4s, the locksmith or dealership must link to Audi's "FAZIT" database in Germany to license the brand-new key and "introduce" it to the car's immobilizer system.
4. Establishing Remote Functions
