Identify the Battery Type
The Audi A8 key fob can use either a CR2032 or a CR1632 battery. To identify which battery your key fob uses, you’ll need to open it first. Both battery types are coin-shaped, but the CR2032 is slightly larger than the CR1632.

Opening the Key Fob
To open the key fob, follow these steps:

- Wiggle the halves apart using your fingers.
If the key fob is difficult to open, you can use a flathead screwdriver:
- Insert the screwdriver into the indentation on the back of the key fob.
- Twist the screwdriver to separate the halves.
Once the key fob is open, you will see the battery inside.
Removing the Old Battery
To remove the old battery, you can either:
- Gently lift it out with your fingers
- Use a flathead screwdriver to pry it out
Be careful not to damage the circuit board inside the key fob while removing the battery. If the battery is stuck, use the screwdriver to get better leverage.

- Ensure the positive side of the battery (marked with a plus sign) is facing down.
- Place the new battery into the battery compartment.
Make sure the battery is seated correctly and securely in place.
Reassembling the Key Fob
Once the new battery is installed, you can reassemble the key fob:
- Place the half with the circuit board on top of the other half.
- Squeeze the two halves together until they snap into place.
Ensure the key fob is securely closed and the key flips out properly.
Testing the Key Fob
After reassembling the key fob, test it to make sure it works correctly. Try locking and unlocking your car to ensure the new battery is functioning properly.
If the key fob does not work, double-check that the battery is installed correctly and the key fob is properly closed.
