Have you noticed that your VW key fob isn’t working like it used to, or worse yet, not at all? VW key fobs are battery-powered, so it’s more than likely that the battery is running out of juice or has stopped working entirely.

Is VW key fob battery replacement difficult? Not at all! It’s actually a quick and simple process, but you’ll need to determine which battery you’ll need for the job. In this quick VW key fob battery replacement guide, you’ll learn which battery your VW key fob uses, when to determine it’s time to change it, and how to change your VW key fob battery. Read on to learn more.

When to Change Your VW Key Fob

The easiest hint to know it's time to change the battery in your VW key fob is when it doesn’t work at all anymore. However, there are earlier warning signs you should take note of. If you notice that some of the buttons don’t work, but others still do, it’s probable that your VW key fob battery is running low on power. The other warning sign is when you need to be closer to the vehicle for the key fob to work, which means the effective range of the key fob decreasing.

Which VW Key Fob Battery Do You Need?

Depending on the age of your key fob, you’ll need one of two batteries.

  • Models pre-1999 (that look like a typical car key but are bulkier) will probably need a CR1632 battery.
  • Models made after 1999 use a key fob that is a pod with a key that is retractable for emergency use. If you own this version, you’ll probably need a CR2032 battery.

What You’ll Need to Replace a VW Key Fob

Fortunately, there aren’t a lot of specialty tools necessary to replace a VW key fob battery, nor do you need expert know-how. Simply grab a small flathead screwdriver (think one you might use for eyeglass or sunglass replacement) and your new battery. After that, it’s a quick procedure, though depending on the age of your key fob determines which route to take.

Replacing Older VW Key Fob Batteries

  • Open the emergency key from the fob.
  • Find the seam of the key fob around the edges. Gently pry it open using the flathead screwdriver.
  • Note how the old battery is placed in the fob. Pop it out from the fob and place the new battery in the same way.
  • Press the key fob back together.
  • Try using the fob to ensure it’s working properly.

Replacing Newer VW Key Fob Batteries

  • Remove the emergency key.
  • Press your thumb at the seam on the top of the fob; no need for a screwdriver.
  • Use your screwdriver to pop out the old battery and install the new one.
  • Push the fob back together and test the key fob.
