What You’ll Need to Replace the Battery

Replacing your Hyundai key fob battery requires minimal tools and materials. Here’s what you’ll need:

• A new CR2032 battery: This is the most common type of battery used in Hyundai key fobs.
• A small flat-head screwdriver: This will be used to pry open the key fob casing.
• Optional: A plastic prying tool: This can help prevent scratching the key fob casing.

Steps to Replace the Battery in a Hyundai Key Fob

Now, let’s get to the heart of the matter – replacing the battery. Follow these straightforward steps:

1. Locate the release button: Most Hyundai key fobs have a small release button on the back. This button releases the metal key from the fob.
2. Release the metal key: Press the release button and gently slide the metal key out of the fob.
3. Identify the seam: With the metal key removed, examine the key fob for a thin seam running around the edge. This seam indicates where the two halves of the casing are joined.
4. Gently pry open the casing: Insert the flat-head screwdriver (or plastic prying tool) into the seam and gently pry the two halves of the casing apart. Be careful not to damage the internal components.
5. Remove the old battery: Once the casing is open, you’ll see the CR2032 battery. Carefully remove the old battery, noting its orientation.
6. Insert the new battery: Place the new CR2032 battery into the fob, ensuring it matches the same orientation as the old battery.
7. Reassemble the key fob: Align the two halves of the casing and press them firmly together until you hear a click, indicating the fob is securely closed.
8. Test the key fob: Try locking and unlocking your Hyundai to confirm the new battery is working correctly.

Tips for a Successful Battery Replacement

Keep these helpful tips in mind for a seamless battery replacement:

• Refer to your owner’s manual: Your Hyundai owner’s manual will provide model-specific instructions and diagrams for replacing the key fob battery.
• Avoid touching the battery terminals: Handle the new battery by its edges to prevent transferring oils from your skin, which can shorten its lifespan.
• Dispose of the old battery properly: Take your old battery to a designated battery recycling center.

By following these steps and tips, you can easily replace the battery in your Hyundai key fob and get back on the road in no time.
