In this video, I will demonstrate the process of changing the internal battery in a Hyundai Ioniq key fob used between 2017 and 2020. The key fob uses a CR2032 battery, and you can easily replace it at home with just a flathead screwdriver and a CR2032 battery.
To get the required battery, you can purchase it online for a few dollars. Once you have the battery, simply push the button to remove the internal key. Next, you can see the keyhole and a slot next to it. Use a flathead screwdriver to insert it into the slot and twist to separate the two halves of the key fob.
Once the fob is open, you will find the battery housed in a plastic area. Use a precision tool or a small flathead screwdriver to carefully remove the old battery and replace it with a new CR2032 battery. Make sure to position the new battery correctly with the positive side facing down, and then click the top back into place. The battery should sit flush in the compartment.
After replacing the battery, reassemble the key fob by clicking the two halves together and inserting the key. Upon successful replacement, the light will come on, indicating that the battery is functional. That’s all it takes to change the internal battery of your Hyundai Ioniq key fob!
