The procedure for replacing the key fob battery in a Jeep Gladiator is very simple. Before proceeding, ensure you have the necessary materials: a flat CR 2450 3V battery and a small flathead screwdriver.

Take the key fob from your vehicle and use the screwdriver to pry open all the side parts of the shell to access the inside. Once the shell is open, you will have access to the battery; to remove it, use the screwdriver again, prying at the edges.

Proceed to extract the old battery and replace it with the new one. Close the shell by simply snapping it back together with your fingers.
