As we enter the year 2023, it’s important to stay updated on how to maintain and replace the battery in your 2020 VW key fob. A key fob is an essential component of modern vehicles, allowing you to lock, unlock, and even start your car remotely. However, like any battery-powered device, the key fob’s battery will eventually run out, requiring replacement. In this article, we will provide you with a comprehensive guide on how to replace the battery in your 2020 VW key fob.

Identifying a Low Battery

Before we dive into the battery replacement process, it’s crucial to recognize the signs of a low battery in your key fob. Some common indicators include a decreased range of operation, unresponsive buttons, or a red warning light on the key fob itself. If you notice any of these symptoms, it’s time to replace the battery.

Gather the Necessary Tools

Replacing the battery in your 2020 VW key fob is a simple task that can be done at home. To get started, you will need a small flathead screwdriver and a replacement CR2032 battery, which can be easily found at most electronic or automotive stores.

Opening the Key Fob

First, locate the small indentation on the side of your key fob. Insert the flathead screwdriver into the groove and gently twist it to pry open the key fob. Be careful not to apply too much force, as you don’t want to damage the casing.

Replacing the Battery

Once the key fob is opened, you will see the battery compartment. Carefully remove the old battery, taking note of its orientation. Insert the new CR2032 battery into the compartment, ensuring that the positive (+) side is facing up. Press down to secure the battery in place.

Closing the Key Fob

After replacing the battery, align the two halves of the key fob and press them together firmly until you hear a click. This indicates that the key fob is securely closed.

Testing the Key Fob

Now that you’ve replaced the battery and closed the key fob, it’s time to test its functionality. Stand near your vehicle and press the lock and unlock buttons to ensure that the key fob is working properly. If the buttons respond and the car locks or unlocks, you’ve successfully replaced the battery.

Additional Tips

Here are a few additional tips to keep in mind:

  • Always keep a spare battery on hand to avoid any inconvenience if the key fob battery dies unexpectedly.
  • Dispose of the old battery properly by recycling it at a designated drop-off point.
  • If you’re unsure about replacing the battery yourself, consult your vehicle’s manual or reach out to a professional for assistance.


By following this guide, you can easily replace the battery in your 2020 VW key fob and ensure that it remains functional. Regularly checking and replacing the battery when necessary will prevent any inconvenience or unexpected issues while using your key fob. Remember to exercise caution during the replacement process and consult a professional if needed. With a well-maintained key fob, you can enjoy the convenience and security it provides for your vehicle.
