Is your Volkswagen Passat key fob not working as reliably as it used to? A common culprit is a dead or dying battery. Fortunately, replacing the battery in your Volkswagen Passat key fob is a straightforward process you can easily do at home. This guide will walk you through each step to get your key fob working like new again.
Before you begin, you’ll need a few simple tools: a new battery and a small flathead screwdriver or similar tool to open the key fob casing. The battery type is typically a CR2032 coin cell battery, but it’s always best to double-check your owner’s manual or the old battery itself to ensure you get the correct replacement.
To start, locate the small notch or seam on your Volkswagen Passat key fob. This is usually on the side or bottom of the fob. Using your flathead screwdriver, gently pry open the casing at this point. Be careful not to apply too much force, as you could damage the plastic housing. Once you have a small opening, you should be able to separate the two halves of the key fob.
With the key fob open, you will see the battery. Note the orientation of the old battery before removing it – usually, the positive (+) side faces upwards. Gently remove the old battery. You may need to use the tip of your screwdriver to help nudge it out of its compartment.
Now, take your new CR2032 battery and install it in the same orientation as the old one. Ensure it is securely placed in the battery compartment.
Finally, carefully snap the two halves of the key fob casing back together until they are firmly closed. You should hear a click as they rejoin. Once reassembled, test your Volkswagen Passat key fob to ensure it is working correctly. If it’s still not working, double-check the battery orientation and ensure you have used a fresh battery. In most cases, replacing the battery will solve the issue and have your key fob functioning perfectly again, giving you reliable remote access to your Volkswagen Passat.
