2 Answers
First, use a screwdriver to remove the key fob cover and gently take off the key blade. Insert the screwdriver into the hole and turn it clockwise to completely separate the two parts of the key fob. After separating the two parts of the key fob, remove the old battery, take out the circuit board, and then replace it with a new battery. There is a button on the key fob with a horn symbol. Pressing it will trigger the car alarm, which has an effective range of over 40 meters. Use it cautiously during quiet nights.
I've always enjoyed handling minor issues myself, and replacing the key battery for the 2018 Kia Sportage is actually quite simple, requiring no professional tools. First, prepare a CR2032 button battery, which can be purchased at supermarkets or electronics stores. Locate the small groove at the top of the key's front side, and gently pry open the cover using a small flat-head screwdriver—be careful not to apply too much force to avoid breaking it. Once opened, you'll see the old battery secured by a metal clip; slowly push it out with your fingers to remove it. Remember to place the new battery with the positive side (+) facing upward into the slot, ensuring proper alignment before pressing the cover back into place. Finally, test the buttons to ensure they respond promptly, just in case the battery isn't seated correctly. The whole process takes about five minutes, saving you unnecessary expenses at the repair shop while also allowing you to clean dust from the key's crevices. For routine maintenance, it's recommended to check the key battery life every two years to reduce the risk of unexpected power loss and maintain a comfortable driving experience.
