How to Change Your VW Key Fob Battery

Part of driving a Volkswagen is getting to enjoy the many amenities that come with your specific model. One of the major conveniences is the key fob – but when your VW key fob battery goes out, don’t be one of the Arlington owners who just cease using it altogether. It’s not difficult to replace the battery in a VW key fob – a few steps, and you’re done. Use this simple step-by-step guide to learn about the VW key battery change. Keep in mind our parts department has the battery for a VW key fob available for order.

Which Battery for VW Key Fob?

  • If you drive an older vehicle (most made before 1999) that looks like a simple VW car key, you’ll likely have to use a CR1632 battery.
  • New models made after 1999 have a fob that looks like a pod with buttons on one side and a retractable emergency key. For this, you’ll probably need a CR2032 battery.
  • Both of these batteries are easily found at hardware, auto parts, and big box stores.

Replace Battery In VW Key Fob: Step-by-Step

Make sure you have the following items to start the process:

  • New CR2032 or CR1632 Battery
  • Small Screwdriver
  • Tape

What’s the tape for? Wrapping the head of the screwdriver in tape helps to avoid cosmetic damage, scratches, and stripping to the VW key fob. After preparing your key fob, follow these steps:

  • Press the button on your VW key fob to eject the emergency key.
  • Locate the seam between the base and the lid.
  • Using your fingers, create a gap between these two components, then slip your screwdriver in between them to pry them apart.
  • Remove the old battery, and reinsert the new one in its place. Before replacing the parts and screws, make sure the positive side of the battery is facing downward. 
  • Reverse engineer the steps above and put the key back together.

Replacing the VW key fob isn’t nearly as difficult as most people think. However, if you’d rather have a professional take care of the job for you, schedule service with one of your maintenance experts at Alexandria Volkswagen.

Starting Your VW With a Dead Key Fob

Many people who neglect to replace the battery just use their keys manually to start their vehicles indefinitely. However, if you’ve found yourself in this situation and panic – don’t worry, you can start your VW manually without having to go directly to a Volkswagen dealer like Alexandria Volkswagen. If you have any difficulties, refer to the owner’s manual.

Tab Covers

Certain Volkswagen models have a cap that seals and protects the cylinder lock on the door. Underneath this cap is a notch you can pop off to expose the lock cylinder. If your model has this setup, insert the key into the cutout below the cap on the driver’s side, and pull the cap tab off with your other hand. You should be able to insert the key to open your door.

VW CCs & VW Touareg Models

Certain rare models like the VW CC and the Touraeg don’t use a bayonet key to open the door. Instead, there’s an emergency key hidden inside the fob itself in case the battery dies. Press the button on the side of the fob and tug on the keyring loop. The hidden key should slide right out! It’s worth noting, however, this key will ONLY ALLOW YOU TO OPEN THE DOOR – NOT START THE ENGINE. Use the key fob to start your car once you gain entry.

If you have keyless access and the battery is low or dead, hold the fob against your steering column and press the start button. This always allows you to start your Volkswagen!
