- Central locking becomes intermittent.
Battery Reference Table
Various Audi designs and years require specific battery types. Below is a general guide to the most common battery requirements:

|---|---|---|
| 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
- Release the Emergency Key: Press the silver release button (or side buttons) to pull out the mechanical key blade.
- Access the Battery Tray: On many modern fobs, the inner plastic tray holding the battery can be removed by squeezing the latches where the emergency key was placed.

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

Troubleshooting Common Issues
Despite their reliability, Audi key fobs can experience technical glitches.
1. Key Not Recognized
If the car stops working to begin and displays a "Key Not Recognized" message, try holding the fob against the designated "key sign" on the guiding column or center console. This enables the car to read the transponder chip via induction, even if the fob battery is dead.

3. Interference
High-power radio towers, cell phone battery chargers, or perhaps remaining in close proximity to a smartphone in a pocket can sometimes hinder the fob's signal. If the fob isn't working, attempt moving it far from other electronic devices.
