The Kia Sorento cars have been in the market for a few years now. And it is no surprise that the key fob for these cars may show signs of battery life degradation. Fortunately, changing the battery in a Kia key fob is very easy to do, and there are a few easy steps you need to follow in order to replace the battery.

Step one: Remove the mechanical key from the key fob by pressing the small button at the back of the device.

Step two: Use a screwdriver to pop off the cover by inserting the tip of the screwdriver in the slot next to where the mechanical key was. Twist it gently to pry off the cover.
