Here’s a detailed, step-by-step guide to replace the battery in your 2020 Hyundai Sonata key fob:

Locate the release button: On the side of your key fob, you’ll find a small release button. This button allows you to separate the physical key from the key fob body.
Release the physical key: Press the release button and gently slide the physical key out of the fob.
Open the key fob: Using your flathead screwdriver or prying tool, carefully insert it into the slot where the physical key was located. Gently pry open the key fob casing. Be careful not to apply excessive force, which could damage the casing.
Remove the old battery: Once the key fob is open, you’ll see the CR2032 battery. Carefully pry out the old battery using your flathead screwdriver or prying tool. Avoid puncturing the battery.
Install the new battery: Insert the new CR2032 battery, making sure the positive (+) side is facing upwards, just like the old battery.
Close the key fob: Align the two halves of the key fob casing and press them together until they snap shut.
Reinsert the physical key: Slide the physical key back into its slot until it clicks into place.

Testing Your Key Fob
