But how do you actually go about doing it? Don’t worry, this guide will walk you through the process step-by-step, making it a breeze even for the most tech-averse drivers.
Gather Your Supplies
Before you dive into the task, make sure you have everything you need:
- New battery: The most important component! You’ll need a CR2032 battery, which is commonly available at most electronics stores and online retailers.
- Small flathead screwdriver: This will be used to pry open the key fob.
- Optional: Tweezers or a small pair of pliers: These can be helpful for removing the old battery if it’s stubborn.
Locate the Battery Compartment
The first step is to locate the battery compartment. On most Volkswagen Jetta key fobs, it’s usually located on the back of the fob, either behind a small cover or a seam. Look for a small latch, button, or groove that can be used to open the compartment.
Open the Key Fob
Once you’ve found the battery compartment, gently pry it open using your flathead screwdriver. Be careful not to apply too much force, as you don’t want to damage the key fob. Start by inserting the screwdriver into the seam or latch and carefully pry the cover open.
Remove the Old Battery
With the compartment open, you’ll see the old battery inside. It’s usually held in place by a small spring or a clip. Gently remove the battery by lifting it out with your fingers or using tweezers if needed.
Insert the New Battery
Now it’s time to insert the new battery. Make sure you’re inserting it with the positive (+) side facing up. This is usually indicated by a “+” sign etched on the battery itself. Once the battery is in place, gently press it down until it clicks into position.
Close the Key Fob
After inserting the new battery, close the battery compartment. Make sure it snaps shut securely. If you’re unsure if it’s closed properly, try gently pushing on the cover to ensure it’s fully latched.
Test the Key Fob
Now, it’s time to test your new battery. Press the buttons on your key fob to see if they’re working. If the buttons respond and the lights illuminate, you’ve successfully replaced the battery!
Troubleshooting Tips
If your key fob still isn’t working after replacing the battery, there could be a few other issues:
- Battery Installation: Double-check that the new battery is properly installed and making good contact.
- Battery Type: Ensure you’ve used the correct type of battery (CR2032).
- Key Fob Damage: If the key fob has been dropped or damaged, the internal components might be faulty.
- Key Fob Programming: In some cases, the key fob might need to be reprogrammed after replacing the battery. This usually requires a visit to a Volkswagen dealership or a qualified mechanic.

While replacing the battery in your Volkswagen Jetta key fob is a simple task, it’s important to remember that batteries have a limited lifespan.
