Replace Remote Control Batteries on a Hyundai Tucson

Model: Hyundai Tucson TL, MK 3 - Years 2015-2021
Part: Key

If your Hyundai's remote control has reduced range or works intermittently, we have the solution for you: replace the batteries inside. This is a very simple task that anyone can do; just follow the few steps we will show you in this video. Press the button that releases the key from the remote and pull it out while holding it down. Use a flathead screwdriver or the key itself to open the two plastic halves; there are no hidden screws, just apply a bit of force. Once open, you can remove the small circuit board inside and replace the battery.
