How to Change the Battery in a VW Key Fob

A dead key fob battery can be a real pain, leaving you stranded and unable to unlock your car. But don’t worry! Changing the battery in your VW key fob is a simple task that you can do yourself in minutes. This guide will walk you through the process step-by-step so you’ll be back on the road in no time.

What You’ll Need

Before you get started, gather the following:

A new CR2032 battery (This is the most common type for VW key fobs, but double-check your owner’s manual to be sure.)
A small flathead screwdriver or a plastic pry tool

Step-by-Step Guide

Once you have your tools and new battery, follow these easy steps:

Locate the release button: Look for a small button or switch on the back of your key fob. This button releases the physical key blade.
Release the key blade: Press the release button and gently slide the key blade out of the fob.
Open the key fob: Use the flathead screwdriver or pry tool to carefully pry open the key fob casing. Start at the notch where the key blade was inserted. There’s usually a small indentation to help you get leverage.
Remove the old battery: The battery will be sitting in a slot, usually secured with a small clip. Gently pry up the battery from the slot, being careful not to damage the clip or any surrounding components.
Replacing a VW Key Fob Battery
Insert the new battery: Place the new CR2032 battery into the slot, making sure the positive (+) side is facing up. Press down gently until you hear the clip snap into place.
Reassemble the key fob: Align the two halves of the key fob casing and press them firmly together until they snap back into place.
Reinsert the key blade: Slide the key blade back into the slot on the key fob until it clicks.

Testing Your Key Fob

Once you’ve replaced the battery, test the key fob by pressing the lock and unlock buttons on the remote. If the car responds, you’re good to go! If not, double-check that the battery is installed correctly and that the contacts are clean.
