To change the battery in a Chevy Avalanche key fob, start by using a small flathead screwdriver to gently pry open the fob along the seam. Once opened, remove the old battery, typically a CR2032, and replace it with a new one, ensuring the positive side is facing up. Snap the fob back together and test the buttons to ensure it's working properly.
