What You’ll Need to Change Your 2017 Hyundai Sonata Key Fob Battery

Before you begin, gather these few simple tools:

Step-by-Step Guide: How to Change the Battery in Your 2017 Hyundai Sonata Key Fob

2. Release the metal key: Press the release button and slide the metal key out of the fob.
3. Separate the key fob halves: Use your flathead screwdriver (or similar tool) to gently pry open the key fob casing. Start by inserting the screwdriver into the slot where the metal key was released. There’s usually a small notch specifically designed for this purpose. Work your way around the perimeter of the key fob, gently applying pressure until the two halves separate. Be careful not to damage the plastic.
4. Remove the old battery: Once the key fob is open, you should see the CR2032 battery. Carefully pry it out using your flathead screwdriver. Avoid puncturing the battery.
5. Insert the new battery: Place the new CR2032 battery into the key fob, ensuring the positive (+) side faces upwards. Press down gently until it clicks into place.
6. Reassemble the key fob: Align the two halves of the key fob and press them together firmly until they snap shut.
7. Reinsert the metal key: Slide the metal key back into its slot until it clicks into place.
8. Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.
