Step-by-Step Guide

Now, let’s get into the step-by-step process of replacing the battery in your Audi S8 key fob.

Step 1: Open the Key Fob

First, flip your key fob over to the back. Look at the bottom where you’ll find an opening in the plastic under a metal piece. Insert your flathead screwdriver into this opening and pry up to remove the back piece of the key fob.

Step 2: Remove the Old Battery

Once the back piece is off, you’ll see the battery inside. Use a tool like a small flathead screwdriver or a precision screwdriver to pry the battery out. If you don’t have a small screwdriver, you can use a paper clip or any small tool that fits into the opening to lift the battery out.

Step 3: Insert the New Battery

Take your new CR2032 battery and ensure the positive side is facing up. Click the battery into place, making sure it sits flat inside the key fob.

Step 4: Reassemble the Key Fob

Line up the plastic back piece with the key fob and snap it back into place. To ensure everything is working correctly, press the button on your key fob and check if the light activates.
