How to Replace the Battery in Your Volkswagen Jetta Key Fob (1999 – 2011)

Introduction to Key Fob Battery Replacement

Replacing the battery in your Volkswagen Jetta key fob is a simple process that can save you time and money. This guide will walk you through the steps needed to replace the battery in your key fob, ensuring that your keyless entry system works perfectly.

Identifying Your Key Fob Model

Before starting, it’s important to identify which version of the key fob you have. There are two devices for the Jetta that look almost identical but have different battery replacement procedures. The key difference is the location of the indicator light.

If your indicator light is in the middle, follow this guide. If it’s in the top corner, refer to a different guide specifically for that model.

Tools and Materials Needed

To replace the battery, you’ll need a few simple tools and materials:

• Flathead screwdriver
• CR2032 battery

If you don’t have the battery, you can purchase it on Amazon.com.

Step-by-Step Battery Replacement

Follow these steps to replace the battery in your Volkswagen Jetta key fob:

Step 1: Flip Out the Internal Key

First, flip out the internal key of your key fob. This will reveal an opening in the middle of the key area.

Step 2: Insert the Screwdriver

Insert your flathead screwdriver into the opening. Push it in and twist to separate the two pieces of the key fob. Set one piece aside for now.

Step 3: Pry Open the Key Fob

Using the same flathead screwdriver, insert it into the space where the key was. Gently pry to push apart the two pieces. Once it starts to open, you can pull it apart with your fingers.

Step 4: Remove the Old Battery

With the key fob open, look for the battery compartment. Insert the flathead screwdriver into the corner of the battery compartment and gently lift the old battery out.

Step 5: Insert the New Battery

Take your new CR2032 battery and ensure the positive side (marked with text and information) is facing down. Click it into place.

You can purchase the battery from Amazon if needed.

Step 6: Reassemble the Key Fob

Line up the pieces of the key fob and squeeze them back together. Ensure everything is securely in place.

Step 7: Test the Key Fob

To make sure you did everything correctly, press one of the buttons on the key fob. The indicator light should turn on, confirming the new battery is working.
