What You’ll Need for a B8.5 Key Fob Battery Replacement
Before you begin, gather these simple tools:

- A small flathead screwdriver or a similar thin, flat tool – for gently prying open the key fob casing.
Step-by-Step B8.5 Fob Battery Replacement Guide
Replacing the battery is a quick procedure. Follow these steps:
-
Locate the Notch: On the back of your B8.5 key fob, you’ll find a small notch or seam. This is where you’ll insert your flathead screwdriver to open the casing.
-
Carefully Pry Open the Fob: Gently insert the flathead screwdriver into the notch and twist lightly. The key fob casing is designed to snap open, so apply steady, but gentle pressure. Avoid forcing it, as you could damage the plastic.
-
Remove the Old Battery: Once the fob is open, you’ll see the old CR2032 battery. It might be held in place by small clips. Carefully remove the old battery, noting the orientation (+ side up).
-
Insert the New Battery: Take your new CR2032 battery and insert it into the battery compartment. Ensure the “+” side of the battery is facing upwards, matching the orientation of the battery you just removed.
-
Reassemble the Fob: Carefully snap the two halves of the key fob casing back together. You should hear a click, indicating it’s securely closed.
You’re All Set!
That’s all there is to it! You’ve successfully replaced the battery in your B8.5 key fob. Test your key fob to ensure it’s working correctly – you should now be able to lock, unlock, and start your Audi without any issues. Regularly replacing your key fob battery can prevent unexpected lockouts and ensure your key fob remains reliable.
