Now, let’s dive into the process of replacing your Audi A6 key fob battery.

Locate the release button: On the back of your key fob, find the small, silver button. This releases the physical key.
Release the physical key: Press the release button and gently slide the physical key out of the fob.
Identify the seam: With the physical key removed, examine the key fob for a small seam running along its edge.
Gently pry open the casing: Carefully insert the flathead screwdriver into the seam and gently pry the two halves of the key fob apart. Be careful not to use excessive force, which could damage the casing.
Remove the old battery: Once open, you’ll see the old CR2032 battery. Carefully remove it, noting the position of the positive (+) side, which should be facing up.
Insert the new battery: Place the new CR2032 battery into the fob, ensuring the positive (+) side is facing up, just like the old battery.
Reassemble the key fob: Align the two halves of the casing and press them together firmly until you hear a click, indicating they are securely closed.
Reinsert the physical key: Slide the physical key back into its slot on the key fob.
Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.

And that’s it! You’ve successfully replaced the battery in your Audi A6 key fob.

Common Issues When Changing Your Key Fob Battery

While replacing your key fob battery is generally straightforward, here are a few common issues and their solutions:

Key fob still not working?: Double-check that you’ve inserted the new battery correctly, with the positive (+) side facing up. If it’s still not working, you may have a faulty battery or another issue requiring professional attention.
Difficulty opening the casing?: If you’re struggling to open the key fob, try using a thinner flathead screwdriver or gently warming the seam with a hairdryer to soften the plastic slightly. Avoid excessive heat, as this can damage the fob.
