How to Replace the Battery in Your Audi A8 Key Fob (2006-2010)

Introduction

Replacing the battery in your Audi A8 key fob is a quick and easy process. Whether your key fob has stopped working or you just want to be prepared, this guide will walk you through each step. You only need a few tools and a few minutes of your time.

Tools and Materials Needed

Before you start, gather the necessary tools and materials. Here’s what you’ll need:

• Flathead screwdriver
• CR2032 battery
• Optional: smaller size screwdriver or paper clip

If you need to purchase a CR2032 battery, you can find one on Amazon at a great price.

Step 1: Remove the Back Cover

First, flip your key fob over and look at the metal part where the key ring attaches. You’ll see an indentation there. Take your flathead screwdriver and insert it under the plastic. Pry gently, and the back piece will come right off.

Step 2: Remove the Old Battery

Now that you have the back cover off, you’ll need a smaller screwdriver or a similar tool to remove the old battery. Insert the tool into the space under the battery and gently pry it out. If you don’t have a smaller screwdriver, a paper clip can also work.

If you need a set of small screwdrivers, you can find a cheap set on Amazon. This set can be very handy for various small tasks.

Step 3: Insert the New Battery

Once the old battery is out, take your new CR2032 battery. Make sure the positive side, marked with a plus sign, is facing up. Insert the battery into the slot and press it down until it sits flat.

It’s important to ensure the battery is properly seated to avoid any issues with functionality.

Step 4: Reassemble the Key Fob

With the new battery in place, it’s time to reassemble your key fob. Take the back piece of plastic and snap it back onto the key fob. Give it a squeeze to make sure it’s securely in place.

Check to see if the light on the key fob turns on. If it does, you’ve successfully replaced the battery.

Testing Your Key Fob

After reassembling your key fob, test it to make sure it’s working correctly. Try locking and unlocking your car to ensure the key fob is functioning as expected.

If the key fob doesn’t work, double-check that the battery is properly seated and the back cover is securely in place.
