How do you change the battery in a Chrysler 300 key fob?

To change the battery in a Chrysler 300 key fob, start by using a small flathead screwdriver to gently pry open the fob along the seam. Once opened, remove the old battery, noting its orientation, and replace it with a new CR2032 battery, ensuring the positive side is facing up. Snap the fob back together securely, and test the key fob to ensure it works properly.
