How to Change Battery in 2012 Hyundai Sonata Key Fob

Is your 2012 Hyundai Sonata key fob acting up? Before you schedule a trip to the dealership, there’s a good chance you can fix the problem yourself with a quick battery swap. Key fobs are powered by small batteries that, like all batteries, eventually die. The good news is that replacing the battery in your 2012 Hyundai Sonata key fob is a simple process that can be done in minutes.

What You’ll Need to Change Your 2012 Hyundai Sonata Key Fob Battery

You only need a few things to change your key fob battery:

• A fresh CR2032 battery: These are commonly found at grocery stores, pharmacies, and online retailers.
• A small flat-head screwdriver: This will be used to pry open the key fob.

How to Change the Battery: A Step-by-Step Guide

1. Locate the release button: On the back of your Hyundai Sonata key fob, you’ll see a small, round button. This is the release button for the physical key.
2. Release the physical key: Press the release button and gently slide the physical key out of the fob.
3. Separate the key fob halves: Use your fingernail or the edge of the flat-head screwdriver to gently pry open the key fob at the seam. You should feel the two halves separate.
4. Remove the old battery: Carefully remove the old CR2032 battery. Note which side faces up so you can install the new one correctly.
5. Install the new battery: Place the new CR2032 battery in the fob, making sure it’s in the same orientation as the old one.
6. Reassemble the key fob: Align the two halves of the key fob and press them together until you hear a click.
7. Test the key fob: Try locking and unlocking your car doors using the key fob. If it doesn’t work immediately, try pressing the buttons a few times or replacing the battery again, ensuring it’s properly installed.

“A common mistake people make is not aligning the battery correctly,” says automotive electronics specialist John Miller. “Make sure it sits flush in the compartment.”

Still Having Trouble?

If you’ve replaced the battery and your key fob is still not working, you may need to reprogram it to your car. You can consult your owner’s manual for instructions or visit a Hyundai dealership for assistance.
