Gathering Your Tools and Identifying the Battery Type

Before you begin, gather the necessary tools: a small flat-head screwdriver, a new CR2032 battery (easily found at most stores), and optionally, a small plastic pry tool. Using the correct battery type is crucial for the proper functioning of your key fob. A CR2032 battery is the specified type for the 2015 Hyundai Sonata key fob.

Step-by-Step Guide to Replacing the Battery

1. Locate the release button: On the side of your key fob, you’ll find a small release button.
2. Release the valet key: Press the release button and slide the valet key out.
3. Open the key fob: Use the valet key or a flat-head screwdriver to carefully pry open the key fob casing. Start at the notch where the valet key was located. Be gentle to avoid damaging the plastic.
4. Remove the old battery: Once the key fob is open, you’ll see the CR2032 battery. Carefully pry it out using your flat-head screwdriver or plastic pry tool.
5. Install the new battery: Insert the new CR2032 battery, making sure the positive (+) side faces upwards.
6. Close the key fob: Align the two halves of the key fob casing and press them together until they snap shut.
7. Test the key fob: Check all the functions of your key fob, including locking/unlocking the doors and remote start (if equipped).

Troubleshooting and Common Issues

Sometimes, even after replacing the battery, the key fob might not work. Here are a few troubleshooting tips:

• Check the battery orientation: Ensure the new battery is installed correctly with the positive (+) side facing up.
• Clean the battery contacts: Use a cotton swab and rubbing alcohol to clean the battery contacts inside the key fob. Corrosion can interfere with the connection.
• Try reprogramming the key fob: In some cases, you may need to reprogram the key fob to your car. Consult your owner’s manual or a professional for instructions. If you’re curious about remote start capabilities, check out our information on the Hyundai remote start key fob.
