How to Change the Remote Key Battery in a Hyundai Tucson

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

Replacing the battery (model CR 2032) in the remote key for this car model is very simple and there are no specific elements of the remote that need disassembly. Start by sliding out the so-called blade, which is the metal key stored inside the remote. At this point, use a small flat tool (a kitchen knife will do) to pry along the edge of the rear shell, which bears the manufacturer's logo, to unclip it and access the battery compartment, ensuring the battery is positioned with the correct polarity.
