Understanding Your Hyundai Key Fob

Gathering Your Tools

You’ll need only a few tools for this task:

• A small flathead screwdriver or a similar tool for prying. A key or a thin butter knife can sometimes work in a pinch.
• A new CR2032 battery. These are readily available at most stores. Don’t be tempted to use a different battery type, as it may not work correctly.
• Optionally, a small flashlight can help you see the internal components of the key fob.

Step-by-Step Guide: Replace Battery in Hyundai Key Fob

1. Locate the release button or notch: Most Hyundai key fobs have a small button or notch on the side or back. This releases the mechanical key.
2. Release the mechanical key: Press the release button and slide the key out.
3. Pry open the key fob: Use your flathead screwdriver to gently pry open the key fob casing along the seam where the two halves meet. Be careful not to damage the plastic. You might hear a slight click as the casing separates.
4. Identify the battery: The CR2032 battery is usually located in a small compartment within the fob.
5. Remove the old battery: Carefully pry the old battery out of its compartment. Avoid puncturing the battery.
6. Insert the new battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side is facing upwards, just like the old battery.
7. Reassemble the key fob: Align the two halves of the key fob casing and press them together until they snap shut.
8. Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.

What if my key fob still doesn’t work after replacing the battery?

Sometimes, the issue isn’t the battery itself. There could be a problem with the key fob’s programming or the car’s receiver. In such cases, it’s best to consult a professional locksmith or your Hyundai dealership.
