Changing Volkswagen Key Fob Battery – 2023


In this article, we will guide you through the process of changing the key fob battery for your Volkswagen vehicle. The key fob is an essential component that allows you to lock, unlock, and start your car with ease. Over time, the battery in your key fob may require replacement, and we will show you how to do it yourself.

Step 1: Gather the necessary tools

Before getting started, make sure you have the following tools ready: a small flathead screwdriver, a new CR2032 battery, and a clean cloth. These tools will help you safely open the key fob and replace the battery.

Step 2: Open the key fob

Locate the small notch on the side of the key fob. Insert the flathead screwdriver into the notch and gently twist it to pry open the key fob. Be careful not to apply too much force to avoid damaging the key fob or causing any scratches.

Step 3: Remove the old battery

Once the key fob is open, you will see the old battery inside. Use the screwdriver or your fingers to carefully remove the old battery from its slot. Take note of the battery’s orientation, as you will need to insert the new battery in the same way.

Step 4: Clean the key fob

While the key fob is open, take a clean cloth and gently wipe the inside to remove any dust or debris. This will ensure that the new battery makes proper contact and functions correctly.

Step 5: Insert the new battery

Take the new CR2032 battery and insert it into the empty slot, making sure it is oriented correctly. Press it down gently until it is securely in place.

Step 6: Close the key fob

Align the two halves of the key fob and press them together firmly until they snap into place. Ensure that all the edges are aligned correctly, and the key fob is securely closed.

Step 7: Test the key fob

Now that the battery has been replaced and the key fob is closed, it’s time to test it. Stand near your car and press the lock or unlock button. If the car responds accordingly, congratulations, you have successfully changed the key fob battery!
