How to Change Battery in Volkswagen Key Fob

However, like any other battery-operated device, the key fob will eventually run out of power and need to be replaced.

In this article, we will show you how to change the battery in your Volkswagen key fob and what to do if you encounter any problems.

What Type of Battery Does a Volkswagen Key Fob Use?

The type of battery that your Volkswagen key fob uses depends on the model and year of your vehicle.

Generally, there are two types of key fobs:

  • First, one looks like a simple car key with a metal blade and a separate lock/unlock button.
  • Second, one looks like a small pod with buttons on one side and a retractable emergency key.

The former usually uses a CR1632 battery, while the latter usually uses a CR2032 battery

These are coin-shaped lithium batteries that can be found in most hardware stores, auto parts shops, or online.

How to Replace the Battery in a Volkswagen Key Fob

Replacing the battery in your Volkswagen key fob is a simple process that only requires a few tools and steps. 

Here is how to do it:

Hold the button on your key fob until the emergency key pops out

You can use this key to unlock the door if the battery is dead.

Locate the seam between the lid and the base of the key fob

You can use your fingers or a small flat-head screwdriver to pry them apart. 

Remove the old battery from the key fob

You may need to use a screwdriver to lift it out of its slot. Make sure to note the orientation of the battery and how it fits into the case.

Insert the new battery into the key fob

Make sure that the positive side (+) faces downward and aligns with the markings on the case.

Snap the lid and the base of the key fob back together

Make sure that they are securely attached and no gaps are visible.

Test your key fob by pressing the buttons and checking if they work properly

If not, you may need to reprogram your key fob or check for other issues.

How to Reprogram a Volkswagen Key Fob

If you have replaced the battery in your Volkswagen key fob but it still does not work, you may need to reprogram it to sync with your vehicle’s computer.

This can be done by following these steps:

  • Insert your emergency key into the driver’s door lock and turn it to unlock the door.
  • Get inside your vehicle and close all doors.
  • Insert your emergency key into the ignition switch and turn it to ON position (do not start the engine).
  • Press and hold the LOCK button on your key fob for about 10 seconds until you hear a beep or see a light flash on your dashboard.
  • Release the LOCK button and remove your emergency key from the ignition switch.
  • Test your key fob by pressing the buttons and checking if they work properly.

If these steps do not work, you may need to visit a Volkswagen dealer or an automotive locksmith to have your key fob reprogrammed professionally.
