2. Integrated Fob Keys (B7 and B8 Platforms)
Starting around 2005, the Audi A4 approached a more integrated design. These secrets typically involve a "dash-insertion" approach where the entire fob is pushed into a slot to begin the engine. These use more complex rolling code file encryption.
3. Audi Advanced Key (Smart Keys)
Most modern-day Audi A4 models (B9 platform and late B8) make use of the "Advanced Key" system. This allows for keyless entry and push-button start. The car discovers the presence of the key through distance sensors. These secrets are the most highly dense and, subsequently, the most expensive to change.
Common Features of Audi A4 Keys:
- Transponder Chips: Small electronic chips that communicate with the ignition to disable the immobilizer.
