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

Step-by-Step Guide: Changing Battery Hyundai Sonata Key Fob

Here’s a simple guide to follow, regardless of your Hyundai Sonata model year:

Locate the release button: On the back of your key fob, you’ll find a small, round release button.
Release the metal key: Press the release button and gently pull out the metal key from the fob.
Separate the key fob halves: With the metal key removed, you’ll notice a small seam or groove along the edge of the fob. Carefully insert the flat-head screwdriver into this seam and gently pry the two halves apart. Be careful not to damage the plastic.
Identify and remove the old battery: Inside the fob, you’ll see the CR2032 battery. Gently pry it out using your screwdriver or fingernail. Take note of the battery’s orientation (+ side up) for installing the new one.
Install the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side is facing up, just like the old battery.
Reassemble the key fob: Align the two halves of the key fob and press them firmly together until you hear a click, indicating they’re securely closed.
Reinsert the metal key: Slide the metal key back into its slot on the fob until it locks into place.

Testing Your New Hyundai Sonata Key Fob Battery

Once you’ve replaced the battery, it’s crucial to test if it’s working correctly:

Lock and unlock your car: Try locking and unlocking your Hyundai Sonata using the key fob buttons.
Start the engine: If your key fob has a push-button start, try starting your car to ensure the signal is strong.

“A common mistake people make is inserting the battery incorrectly. Always double-check the orientation to avoid any issues,” advises John Miller, Senior Automotive Technician at CarDiag Tech Workshop.
