How to Change the Battery in a VW Key Fob

Couple Walking Toward their Volkswagen

Do you need to know how to change the battery in a VW key fob? You can visit our service center near East St. Louis when you need a VW key fob battery, but most drivers can handle a VW key fob battery replacement on their own. All you need to do is follow the instructions below.

Which VW Key Battery Do I Need?

Learning how to change the battery in a VW key fob isn’t difficult, but it is important to know the right type of battery for your particular model. So, what key fob battery do you need? Auffenberg Volkswagen is happy to help you find what your vehicle requires:

  • For older VW vehicles with a fob that resembles a simple Volkswagen car key, it is most likely that your key fob requires a CR1632 battery.
  • For a majority of new models manufactured after 1999, the key fob will resemble a small pod with buttons on one side, and it will have a retractable emergency key. For this type of key fob, you will probably have to purchase a CR2032 battery.

VW Key Battery Replacement: Your Step-by-Step Guide

Now that you have the right key fob battery, what are the next steps? Regardless of what VW vehicle you drive, replacing the battery in your VW key fob should be a hassle-free project. After you have found a small screwdriver and the right battery, you can begin the key fob battery replacement process. To avoid scratching and damaging your fob, wrap the flat-head screwdriver with a small piece of tape.

  1. Hold the button on your Volkswagen key fob until the emergency key pops out.
  2. Grasp the fob firmly in your hand, or attach it to a small metal key ring that you can hold on your index finger.
  3. Find the seam where the lid and base of your key fob connects. Use your fingers to create a small distance between the two, and then use the flat-head screwdriver to finish prying them apart. Be careful during this step so that you don’t scratch or cause damage to the key fob.
  4. Remove the dead car key battery and swap it for the fresh one. The positive side of the car key battery should be placed downward.
  5. Close the remote case tightly to hold everything in place. Once this step is complete, you are ready to hit the Caseyville streets!

How to Start the Car without Your Smart Key

It’s every driver’s nightmare. You just leave the house for that important job interview or a long-awaited family gathering. You press the button on your key fob over and over again, but it doesn’t work. It’s likely that the key fob battery needs to be replaced.

Do not worry! Even older VW key fobs come with an emergency key or a bayonet key. With this key, no power is needed. It will still work on vehicles with keyless entry or a push button start feature even if the car key battery needs to be replaced. All you have to do is hold the emergency key below the ignition and the engine should start.

Volkswagen Key Replacement

If a key fob battery replacement is not the culprit, or you have misplaced your key, you do not have to panic. Car key replacement can be expensive, and Volkswagen is no different. If possible, try to keep a spare key. If you don’t have a spare key and need a VW key replacement, visit Auffenberg Volkswagen today. When you stop by the dealership, you will need to have your driver’s license and your proof of ownership.

If you’ve just picked up a new VW key fob, you may need to spend some time programming the key before it will work as it should. We can help you with this at our VW service center near Madison and Caseyville.
