What Battery Does a VW Key Fob Take?

Knowing what battery your VW key fob takes is essential for keeping your car on the road. A dead key fob battery can leave you stranded, so understanding how to identify and replace it is crucial. This article will guide you through everything you need to know about VW key fob batteries, from identifying the correct type to replacing it yourself.

VW Key Fob Batteries: More Than Meets the Eye

While it might seem simple, choosing the right battery for your VW key fob requires a little understanding of the different types available. Here’s a breakdown:

CR2032: This is the most common type of battery found in VW key fobs. It’s a small, coin-shaped battery that provides reliable power for keyless entry and ignition systems.
CR2025: While less common than the CR2032, some VW key fob models might use this battery type. Always double-check your owner’s manual or look for markings on the existing battery to be sure.

Finding the Right Battery for Your VW

Identifying the correct battery for your VW key fob is straightforward. Here’s how:

Consult Your Owner’s Manual: Your VW owner’s manual will specify the correct battery type for your specific make and model.
Examine the Existing Battery: Open your key fob (more on that later!) and look at the existing battery. The battery type (e.g., CR2032) is usually printed on the battery itself.
Online Resources: Websites like KEYFOBPROG offer information on various car key fob batteries, including those for Volkswagen models.

How to Change a VW Key Fob Battery

Don’t worry; changing your VW key fob battery is typically a quick and easy DIY task. Here’s a general guide:

Locate the Release Button or Slot: Most VW key fobs have a small release button or slot. Press or slide it to release the physical key.
Open the Key Fob: Use the physical key or a small flat-head screwdriver to pry open the key fob casing. Be gentle to avoid damaging the internal components.
Remove the Old Battery: Carefully remove the old battery. Note its position and polarity (+/-) for installing the new battery.
Insert the New Battery: Place the new battery in the same position as the old one, ensuring the polarity is correct.
Reassemble the Key Fob: Align the two halves of the key fob and press them together until they snap securely back into place.
Test the Key Fob: Check if the key fob functions correctly by locking and unlocking your car doors and trying the ignition.

Common Issues & Troubleshooting

Key Fob Still Not Working? If replacing the battery doesn’t solve the problem, there might be other issues with your key fob, such as programming or antenna problems. It’s best to consult a qualified automotive locksmith or dealership for assistance.
Key Fob Range Issues: If you find yourself standing closer to your car to lock or unlock it, your key fob battery might be low, or there might be interference from other electronic devices. Try replacing the battery first.
