Shows and Synchronization

A common point of confusion for Audi owners is the difference between "integrating" a key and "shows" a key.

2. Physical Button Failure

With time, the rubber membranes inside the fob can use down. If a specific button (like the trunk release) quits working while others work, the internal micro-switch might be damaged. In this case, the shell can sometimes be changed, however frequently a brand-new fob is needed.

3. Interference

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