Before you can start, you need to release and remove the physical key from the electronic key of your Hyundai Tucson by simply pressing the relevant release button. Next, pry off and remove the rear cover of the key using a thin but sturdy tool.

Once you have freed the rear cover, you will access the exhausted battery, which you need to remove, completing the disassembly. To fit the new battery, simply follow this procedure in reverse, and the replacement will be correctly completed.
