How to Change Your Hyundai Sonata Key Fob Battery

A dead key fob battery can be incredibly frustrating. Luckily, replacing it is usually a quick and easy DIY job. Whether you own a 2015, 2017, or a newer model, the process is similar. You’ll need a small flathead screwdriver or a similar tool and, of course, a fresh CR2032 battery. Let’s dive into the step-by-step instructions.

Locate the release button: On the side of your Hyundai Sonata key fob, you’ll find a small release button. This button is often marked with a key symbol or a small indentation.
Release the valet key: Press the release button and gently slide the valet key out of the fob.
Separate the key fob halves: Using the valet key or a small flathead screwdriver, carefully pry open the key fob casing. Start by inserting the tool into the slot where the valet key was located. Gently twist or lever the tool to separate the two halves of the key fob. Be careful not to damage the plastic.
Remove the old battery: Once the key fob is open, you should see the old CR2032 battery. Use your screwdriver or fingernail to gently pry it out of its compartment.
Install the new battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side is facing upwards.
Reassemble the key fob: Align the two halves of the key fob and press them together until they snap securely shut.
Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.

Common Issues and Troubleshooting

Sometimes, you might encounter a few hiccups when changing your key fob battery. Here are some common issues and how to resolve them:

Key fob won’t open: If you’re struggling to separate the key fob halves, try using a slightly different tool or applying a bit more pressure. Be gentle to avoid breaking the plastic.
Key fob still doesn’t work after battery replacement: Double-check that you’ve inserted the new battery correctly with the positive side facing up. If it’s still not working, it’s possible the key fob itself is faulty and needs to be replaced.
Difficulty locating the release button: Refer to your owner’s manual for the exact location of the release button on your specific Hyundai Sonata model.
