Is your 2015 Hyundai Sonata key fob acting up? Before you schedule a service appointment, it might be a simple battery issue! This guide will walk you through the quick and easy steps to replace the battery in your key fob, saving you time and money.

Replacing the battery in your key fob is a task most car owners can handle themselves. Let’s get started.

What You’ll Need

• A fresh CR2032 battery
• A small flat-head screwdriver

Locating the Battery Compartment

1. Examine your key fob: Look for a small release button or notch on the back or side.
2. Release the mechanical key: Press the release button and gently slide the mechanical key out of the fob.
3. Identify the battery compartment: With the mechanical key removed, you should see the battery compartment cover.

Replacing the Battery

1. Open the compartment: Carefully wedge the flat-head screwdriver into the notch on the battery cover and gently pry it open.
2. Remove the old battery: Take note of the battery’s orientation (+/-). This will help you correctly install the new one.
3. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces up (or matches the orientation of the old battery).
4. Close and secure the cover: Align the cover and press it firmly until it snaps back into place.
5. Reinsert the mechanical key: Slide the mechanical key back into its slot until you hear a click.

Testing Your Key Fob

After replacing the battery, test all key fob functions (lock, unlock, panic) to ensure it’s working properly. If you’re still experiencing issues, it’s best to consult your owner’s manual or reach out to a Hyundai dealership for further assistance.

“It’s always a good idea to have a spare battery on hand,” says John Davis, Senior Automotive Technician at Car Clinic. “You never know when your key fob battery will decide to die, and having a spare ensures you’re never stranded.”
