2. Physical Button Failure

In time, the rubber membranes inside the fob can wear down. If a specific button (like the trunk release) stops working while others operate, the internal micro-switch may be damaged. In this case, the shell can sometimes be replaced, however frequently a new fob is required.

3. Interference

High-power radio towers, cell phone chargers, or even being in close distance to a smartphone in a pocket can sometimes hinder the fob's signal. If the fob isn't working, attempt moving it away from other electronic devices.

The Future: Smartphone Integration

Audi is slowly approaching the "Digital Key" period through the myAudi app. On more recent designs geared up with Audi link, owners can use their mobile phones as a key via Near Field Communication (NFC). This allows the motorist to lock, unlock, and begin the lorry without a physical fob.
