Is your 2019 Volkswagen Passat key fob starting to feel a little unresponsive? Perhaps you need to be closer and closer to your car for it to unlock, or maybe it’s stopped working altogether. One of the most common culprits for a failing key fob is a dead battery. Fortunately, replacing the battery in your VW Passat key fob is a simple task you can easily do yourself at home in just a few minutes. No need to schedule a service appointment or pay dealership prices!
This guide will walk you through the step-by-step process of changing the battery in your 2019 VW Passat key fob. By following these instructions, you’ll have your key fob working like new again in no time.
What You’ll Need
Before you begin, gather these simple items:
- A new CR2032 battery: This is the standard button cell battery size for most VW Passat key fobs. You can find these at most drugstores, supermarkets, and online retailers.
- A small flathead screwdriver or similar tool: A small eyeglass screwdriver or even the tip of a key will work to help you open the key fob casing.
- A soft cloth (optional): This can be used to protect the key fob from scratches while you’re working on it.
Step-by-Step Guide to Changing Your VW Passat Key Fob Battery
Now that you have everything you need, let’s get started with replacing your key fob battery.
Step 1: Locate the Release Button or Latch
Examine your VW Passat key fob closely. You’ll need to find the small release button or latch that allows you to separate the key portion from the fob casing. On most 2019 VW Passat key fobs, this is usually a small black button located on the side or bottom edge of the key fob, often near the metal key ring.
Step 2: Remove the Emergency Key
Press and hold the release button or slide the latch you located in Step 1. While holding the button or latch, gently pull the metal emergency key away from the plastic fob casing. The key should slide out relatively easily. Set the metal key aside in a safe place.
Step 3: Open the Key Fob Casing
With the emergency key removed, you will now see a small slot or seam where the two halves of the key fob casing join together. This is where you’ll use your flathead screwdriver or prying tool.
Carefully insert the tip of your flathead screwdriver into the slot or seam. Gently twist the screwdriver to separate the two halves of the key fob casing. Be patient and avoid using excessive force, as you don’t want to damage the plastic casing. You may hear a small click as the casing begins to separate.
Once you have created a small opening, you can usually use your fingers to gently pull the two halves of the key fob casing completely apart.
Step 4: Remove the Old Battery
With the key fob casing open, you will see the old CR2032 battery. It’s usually held in place by small clips or a retaining bracket.
Take note of the orientation of the battery – specifically, which side is facing up (+ or -). This is important so you insert the new battery correctly.
Gently pry the old battery out of its housing. You can use your fingertip or the edge of your small screwdriver to carefully lift it out.
Step 5: Insert the New Battery
Now, take your new CR2032 battery. Make sure the polarity is correct, matching the orientation of the old battery you just removed. Typically, the positive (+) side of the battery should be facing upwards.
Slide the new battery into the battery compartment, ensuring it’s securely seated under the retaining clips or bracket. You should feel it snap into place.
Step 6: Reassemble the Key Fob
Carefully align the two halves of the key fob casing back together. Press them firmly until they snap back into place, ensuring there are no gaps.
Finally, slide the metal emergency key back into the key fob until it clicks securely.
Step 7: Test the Key Fob
Now it’s time to test your newly battery-powered key fob! Go to your 2019 VW Passat and try unlocking and locking the doors using the key fob buttons. The range should be restored, and your key fob should be working perfectly again.
Conclusion
Congratulations! You have successfully changed the battery in your 2019 VW Passat key fob. This simple DIY task can save you time and money compared to going to a dealership. By following these easy steps, you can keep your key fob functioning properly and avoid the inconvenience of a dead battery. Remember to replace your key fob battery periodically to ensure optimal performance and avoid being caught out with a non-functional remote.
