How to Replace the Key Fob Battery in a 2019 VW Jetta

If you’re here, you’re probably in need of replacing the battery in your 2019 Volkswagen Jetta key fob. No worries! This guide will walk you through the process step by step.

What You’ll Need:

  • A small flathead screwdriver (or a similar tool)
  • A replacement battery (typically a CR2032 or CR2025, but check your fob to confirm)
  • Clean workspace

Step-by-Step Instructions:

  1. Open the Key Fob
    Look for a small notch or slot on the side of the key fob where you can insert the screwdriver. Carefully pry it open to avoid damaging the casing.

  2. Remove the Old Battery
    Once opened, you’ll see the battery inside. Note its orientation (which side is positive and negative) before removing it.

    • Gently lift it out using your fingers or the screwdriver.
  3. Insert the New Battery
    Place the new battery in the same orientation as the old one. Make sure it fits snugly.

  4. Reassemble the Key Fob
    Line up the halves of the fob and press them back together. You should hear a click when they snap into place.

  5. Test the Key Fob
    Stand near your car and press any button on the fob to make sure it’s working properly.

Tips:

  • If the fob still doesn’t work, double-check the battery orientation or try replacing the battery again with a new one in case it was defective.
  • Consider keeping an extra battery in your glove compartment for future use!

Where to Buy:

You can purchase the replacement battery at most auto parts stores, electronic shops, or even online. Be sure to choose the correct type for your fob.

Hope this helps you get back in your car smoothly! If you have any other questions or tips, feel free to share!

Great tip! I usually just end up searching for things forever. Any safety precautions to keep in mind while doing this?

Yes, it’s best to avoid using metal tools directly on the battery to prevent any short circuits. Also, always ensure the fob is off while replacing the battery.

Good point! I didn’t think about the short circuit risk. How do you actually get into the fob to replace the battery?

To access the battery compartment, use the flathead screwdriver to carefully pry open the fob. There’s a small notch on the side that makes this easier. Just go slow to avoid breaking it!

Thanks for that! I was worried I’d break my fob trying to get it open. What about putting in the new battery? Any specific orientation?

Absolutely! The positive side of the CR2032 battery should face upwards when you insert it. You can check the diagram inside the compartment for orientation details.

Thanks for clarifying! I always get confused about that. Once it’s all back together, is there anything else I need to do?

Once you’ve reassembled the fob, just test it to make sure everything is working as it should. If it doesn’t respond, you might want to check if the battery is seated correctly.

Testing is key! What if it still doesn’t work? Is there a chance the fob itself is broken?

If it still doesn’t work after the battery replacement, it could be an issue with the fob itself. You might need to get it reprogrammed or consider a replacement from a dealer.

What a hassle! I really hope it doesn’t come to that. But hey, at least DIY-ing the battery is a good skill to have!

You’re right! And if you screw it up, just think of it as an opportunity for learning. Plus, it’s a great conversation starter at parties! “You won’t believe what I did with my key fob!”

To replace the key fob battery in a 2019 VW Jetta, you’ll need a CR2032 battery. It’s a common type, so you can find it at most electronics or auto parts stores.

I just replaced mine last week! Picked up my CR2032 battery at Walmart for about $3. Very affordable!

That’s correct! I recommend brands like Energizer or Duracell. They seem to last the longest.

I usually buy Panasonic batteries; they work just as well for me!

You can also find CR2032 batteries online on sites like Amazon or eBay if you prefer shopping from home!

Good idea! Sometimes stores run out of stock, especially for specific brands.
