How to Change the Battery in the Hyundai Tucson Key Fob

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

Let's see how to change the battery in a smart key for the Hyundai Tucson. Press the small side button located near the base of the key and pull out the emergency metal blade. Insert a flat screwdriver into the gap created after removing the blade and lever it to open the plastic shell. Separate the two halves with a click. Remove the old battery, being careful of the polarity; usually, the positive terminal faces upwards. The battery you need is a common CR2032, which can be easily obtained from a newsagent or an electronics or hardware store. Insert the new battery in the same position, snap the two halves back together until they click, and reinsert the metal blade.
