Ready to get started? Here’s a simple guide that applies to most Hyundai Sonata models:

Locate the key release button: On the back of your key fob, you’ll find a small button. Press this button to release the metal key.
Open the key fob: With the metal key removed, you’ll see a small slot. Carefully insert the flathead screwdriver into the slot and gently pry open the casing. You might hear a slight click when it separates.
Remove the old battery: The CR2032 battery will be easily visible. Gently pry it out using your screwdriver or fingernail.
Install the new battery: Make sure the positive (+) side of the new battery is facing up, just like the old one.
Reassemble the key fob: Align the two halves of the casing and press them together firmly until you hear a click.
Test the key fob: Try locking and unlocking your Sonata to make sure the new battery is working properly.

Troubleshooting Tips

If your key fob still isn’t working after replacing the battery, try these quick fixes:

Check the battery orientation: Ensure the new battery is installed with the positive (+) side facing up.
Clean the battery contacts: Over time, a small amount of corrosion can build up on the battery contacts inside the key fob. Use a cotton swab and a bit of rubbing alcohol to gently clean the contacts.
Reprogram the key fob: In some cases, you might need to reprogram your key fob after replacing the battery. Consult your Sonata’s owner’s manual for instructions on how to do this.

Pro Tip from John Smith, Senior Automotive Technician: “Always make sure to purchase high-quality CR2032 batteries from a reputable brand. Cheap batteries may leak or die quickly, leading to more headaches down the road.”
