- The "Key Not Recognized" alerting appears on the control panel (Virtual Cockpit).
- The LED indicator on the fob no longer flashes when buttons are pressed.
- Central locking ends up being periodic.
Battery Reference Table
Different Audi designs and years need particular battery types. Below is a basic guide to the most typical battery requirements:
| Audi Fob Type | Typical Models | Battery Type |
|---|---|---|
| Older Flip Key | A4 (B6/B7), A6 (C5) | CR2032 or CR1620 |
| Circular/Rounded Smart Key | A4/A5 (B8), Q5 (8R) | CR2032 |
| Modern Rectangular Fob | A3, A4 (B9), Q7, Q8 | CR2032 |
| Newest Slim/Glossy Fob | e-tron, A6 (C8), A8 (D5) | CR2032 |
Steps to Replace the Battery
- Launch the Emergency Key: Press the silver release button (or side buttons) to take out the mechanical key blade.
- Access the Battery Tray: On numerous modern fobs, the inner plastic tray holding the battery can be eliminated by squeezing the latches where the emergency situation key was placed.

- A licensed Audi Dealership.
- A qualified vehicle locksmith professional with specialized VAG (Volkswagen Auto Group) diagnostic tools.
The Cost of Replacement

|---|---|---|
| Key Fob Hardware | ₤ 150 - ₤ 350 | ₤ 100 - ₤ 250 |
| Laser Cutting (Blade) | ₤ 50 - ₤ 100 | Included/Variable |
| Programming Fee | ₤ 100 - ₤ 200 | ₤ 75 - ₤ 150 |
| Total Estimated Range | ₤ 300 - ₤ 650 | ₤ 175 - ₤ 400 |
