Audi S5 Key Fob Battery Replacement Guide (2008-2010)

Introduction

Replacing the battery in your Audi S5 key fob is a simple task that you can do at home. This guide will walk you through the steps needed to replace the battery in your key fob. All you need is a flathead screwdriver and a CR2032 battery. Follow these instructions, and you’ll have your key fob working again in no time.

Tools You Will Need

Before you start, make sure you have the necessary tools. You’ll need the following:

• Flathead screwdriver
• CR2032 battery

If you don’t have a CR2032 battery, you can buy one on Amazon. They are affordable and come in packs, so you’ll have spares for future use.

Step 1: Open the Key Fob

First, flip the key fob over to the back. Locate the opening in the plastic under the metal part at the bottom. Insert your flathead screwdriver into this opening and pry it open. The back of the key fob will come off easily.

Step 2: Remove the Old Battery

With the back off, you’ll see the battery. To remove it, you’ll need to insert something into the small opening next to the battery. A precision screwdriver works well for this, but you can also use a paper clip or similar tool. Pry the battery up gently to remove it.

Make sure to dispose of the old battery properly. Lithium coin batteries can be harmful to the environment, so consider recycling them.

Step 3: Insert the New Battery

Take your new CR2032 battery and make sure the positive side is facing up. The positive side usually has a plus sign on it. Place the battery into the compartment and press it down until it clicks into place.

Step 4: Reassemble the Key Fob

Once the new battery is in place, put the back cover of the key fob back on. Press down until it snaps securely into place. To ensure you’ve done everything correctly, press a button on the key fob to see if the light turns on. If it does, you’ve successfully replaced the battery.

Tips and Tricks

Here are some additional tips to make the process easier:

• Use a precision screwdriver set for better control.
• Consider buying a multi-pack of CR2032 batteries for future use.
• Check that the battery is properly seated before closing the key fob.

If you need a precision screwdriver set, you can find one on Amazon.com.
