How to Change Battery in ID4 Key Fob

The Volkswagen ID4 key fob is a sleek and modern piece of technology that allows you to access and start your car with ease. Like all key fobs, it relies on a small battery to power its functions. Over time, this battery will inevitably drain, requiring you to replace it to keep your key fob working. Changing the battery in your ID4 key fob is a straightforward process that you can do yourself with just a few simple tools. This guide will walk you through the steps to get your key fob back in action.

What You’ll Need to Change Your ID4 Key Fob Battery

Before you begin, gather the following items:

A new CR2032 battery (This is the most common type for key fobs)
A small flat-head screwdriver
Optional: A small container to hold the screws

Step-by-Step Guide to Replacing the Battery

Follow these steps to replace the battery in your VW ID4 key fob:

Locate the release button. On the back of your key fob, you’ll find a small, rectangular button. This is the release button for the physical key.
Remove the physical key. Press and hold the release button while gently sliding the physical key out. Keep the key and the fob together.
Identify the battery cover. With the physical key removed, you’ll notice a small indentation on the edge of the fob. This indentation marks the location of the battery cover.
Pry open the battery cover. Carefully insert the flat-head screwdriver into the indentation. Gently apply pressure to pry open the battery cover. Be careful not to damage the cover or the fob itself.

Opening the ID4 Key Fob Battery Cover

Remove the old battery. Once the cover is open, the old CR2032 battery will be visible. Gently remove the battery, noting the orientation of the positive (+) and negative (-) sides.

Reinsert the physical key. Slide the physical key back into the fob until it locks securely.
Test the key fob. Press the buttons on the key fob to ensure that it is functioning properly.

Troubleshooting Tips

If your key fob is still not working after replacing the battery, here are a few things you can try:

Check the battery orientation: Ensure that the new battery is installed correctly with the positive (+) and negative (-) sides matching the markings in the fob.
Clean the battery contacts: Use a cotton swab and a bit of rubbing alcohol to clean the battery contacts inside the fob. This can remove any corrosion that might be interfering with the connection.
Resynchronize the key fob: Your owner’s manual should have instructions for resynchronizing your key fob with your vehicle.
