If you’re experiencing issues with your 2017 Hyundai Sonata key fob, like decreased range or unresponsive buttons, it might be time for a battery change. Luckily, this is a simple task you can do yourself in minutes. This guide will walk you through the process step-by-step.
What you’ll need:
- A new CR2032 battery (you can find these at most supermarkets, electronics stores, and auto parts stores)
- A small flat-head screwdriver
How to change the battery in your 2017 Hyundai Sonata Key Fob:
- Locate the release button. On the back of your key fob, you’ll see a small, round button.
- Release the mechanical key. Press the release button and gently slide the mechanical key out of the fob.
- Separate the fob halves. Use your fingernail or the flat-head screwdriver to carefully pry open the key fob at the seam where the mechanical key was inserted. You should hear a slight click when it separates.
- Identify the battery. Inside the fob, you’ll see the CR2032 battery.
- Remove the old battery. Gently pry out the old battery using the flat-head screwdriver. Be careful not to damage the fob or the battery contacts.
- Insert the new battery. Make sure the positive (+) side of the new battery faces up, matching the orientation of the old battery.
- Reassemble the fob. Align the two halves of the fob and press them firmly together until you hear a click.
- Reinsert the mechanical key. Slide the mechanical key back into its slot on the fob.
- Test the key fob. Make sure all the buttons are functioning correctly.
Troubleshooting:
- If your key fob still isn’t working after replacing the battery:
- Double-check that the new battery is properly installed and the positive (+) side is facing up.
- Clean the battery contacts inside the fob with a cotton swab and rubbing alcohol.
- Consult your owner’s manual or contact a Hyundai dealership for further assistance.
