Steps to Change the 2019 Kia Optima Key Fob Battery

Once you have your new CR2032 battery, follow these simple steps to replace the old one:

Locate the release button: On the side of your key fob, you’ll find a small release button. Press this button to release the valet key.
Use the valet key: Insert the tip of the valet key into the small slot on the key fob casing. Gently pry open the casing. Be careful not to break the casing.
Remove the old battery: Once the casing is open, you’ll see the old CR2032 battery. Carefully remove it using your fingernail or a small flathead screwdriver.
Insert the new battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side is facing up.
Close the key fob: Snap the two halves of the key fob casing back together. Make sure it closes securely.
Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.

Common Issues and Troubleshooting

Sometimes, even after replacing the battery, your key fob might not work. Here are a few common issues and how to troubleshoot them:

Key fob still not working: Double-check that you installed the battery correctly, with the positive (+) side facing up. If it’s installed correctly, try reprogramming your key fob. Refer to your owner’s manual for instructions on how to do this.
Key fob casing broken: If you accidentally break the casing while trying to open it, you might need to replace the entire key fob. Contact your Kia dealership for assistance.
