How to Change VW Key Fob Battery

Table of Contents

Having a functioning key fob is essential for the convenience and security of your Volkswagen vehicle. However, over time, the battery in your key fob may start to lose its charge, resulting in a weakened signal or even complete failure. In this article, we will guide you through the process of changing the battery in your VW key fob, ensuring that you can continue to enjoy the benefits of keyless entry and other key fob features.

Why Change the VW Key Fob Battery?

Before we dive into the step-by-step process of changing the battery in your VW key fob, let’s first understand why it is necessary to do so. The key fob battery powers the transmitter that sends signals to your vehicle, allowing you to lock and unlock the doors, open the trunk, and even start the engine without inserting the key into the ignition. Over time, the battery’s charge depletes, resulting in a weaker signal and reduced functionality. Changing the battery will restore the key fob’s performance and ensure that you can continue to use it effortlessly.

Identifying the Correct Battery

Before you begin the battery replacement process, it is crucial to identify the correct battery for your VW key fob. Different models and years of Volkswagen vehicles may require different types of batteries. To determine the correct battery for your key fob, follow these steps:

Locate the model number of your key fob. This information can usually be found on the back of the key fob or in the owner’s manual.
Refer to the owner’s manual or contact your local Volkswagen dealership to find the specific battery type required for your key fob model.

Once you have identified the correct battery, you can proceed with the battery replacement process.
