Identifying Your VW Golf Mk5 Key Fob

Before we dive into the battery replacement, let’s make sure we’re talking about the right key fob. The Mk5 Golf typically has a two or three-button remote with a flip-out key.

What You’ll Need to Change the Battery in your VW Golf MK5 Key Fob

You only need a couple of things:

A new CR2032 battery. These are widely available at most stores that sell batteries. Pro tip: buy a multi-pack, you’ll need to replace it again eventually!
A small flathead screwdriver or a plastic pry tool. Something thin enough to fit into the seam of the key fob. Avoid using anything too sharp that could damage the plastic.

Step-by-Step Guide: How to Change the Battery in a VW Golf Mk5 Key Fob

Locate the release button: On the side of your key fob, there’s a small button. This is the key release. Press it to release the metal key from the fob.
Use the key to pry open the fob: With the metal key released, gently insert it into the slot on the side of the key fob. You’ll feel a slight resistance. Gently twist the key to separate the two halves of the fob. Be careful not to force it.
Locate the old battery: Inside the fob, you’ll see the CR2032 battery. It’s usually held in place by a small clip.
Remove the old battery: Use your flathead screwdriver or plastic pry tool to carefully lift the old battery out of its housing. Avoid puncturing the battery.
Install the new battery: Insert the new CR2032 battery, making sure the positive (+) side is facing upwards, just like the old battery.
Close the key fob: Align the two halves of the key fob and press them together until they snap shut.
Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.

Common Issues and Troubleshooting

Sometimes, even after replacing the battery, your key fob might not work. Here are a few things to check:

Battery orientation: Make sure the new battery is installed correctly with the positive (+) side facing up.
Key fob reprogramming: In rare cases, you might need to reprogram your key fob after replacing the battery. Your owner’s manual should have instructions on how to do this.

“Often, people overlook the simple things,” says John Smith, Senior Automotive Technician at Smith’s Auto Repair, “Double-checking the battery orientation can save a lot of headaches.”
