Replacing Remote Key Battery for Hyundai Tucson

Model: Hyundai Tucson JM, MK 1 - Years 2004-2009
Part: Key

Is the battery in your Tucson key dead? Want to replace it? Here's how to disassemble the key. Take the remote key and separate the piece: remove the rear shell of the key by prying it off. Using a screwdriver, extract the dead battery. Take a new battery and insert it into the key (of the same size and voltage). Fit the new battery, reassemble the cover, and screw in the screws. Join the plastic of the rear cover to the key. Check the operation of the Tucson remote key with its functional buttons.
