Audi S4 Key Fob Battery Replacement (2000 – 2006)

Introduction

Replacing the battery in your Audi S4 key fob is a simple task that can save you time and money. Whether you have a CR2032 or CR1632 battery, this step-by-step guide will help you through the process.

Tools You’ll Need

Before you begin, make sure you have the following tools:

• Replacement battery (CR2032 or CR1632)
• Flathead screwdriver

Both of these batteries can be easily purchased online. I recommend checking out the links provided for a good deal.

Step 1: Open the Key Fob

The first step in replacing the battery is to open the key fob. To do this, flip out the key and locate the two halves of the device. Grab on either end and pull to separate them.

If you find this difficult, use your flathead screwdriver. On the back of the fob, there is an opening. Insert the screwdriver and twist to open the fob more easily.

Step 2: Remove the Battery

Once the key fob is open, you’ll see the battery inside. There are two types of batteries that might be in your key fob: the smaller CR1632 or the larger CR2032.

If the battery doesn’t come out easily, gently pry it up with your screwdriver. Identify which type of battery you have so you can purchase the correct replacement.

Step 3: Insert the New Battery

Take your replacement battery and make sure the positive side is facing down. Set it into place inside the key fob.

This process is the same whether you have a CR2032 or CR1632 battery.

Step 4: Reassemble the Key Fob

After the new battery is in place, reassemble the key fob by aligning the two halves and pressing them together until they click.

Ensure everything is securely in place before testing the key fob.

Conclusion

That’s all it takes to replace the battery in your Audi S4 key fob. This simple task can be done in just a few minutes and will save you from the inconvenience of a dead key fob battery.
