Identify the Battery Orientation: Once the key fob is open, you’ll see the CR2032 battery. Before removing the old battery, take a moment to observe how it’s positioned in the compartment. Note whether the positive (+) side is facing up or down. This is important for correct installation of the new battery. Typically, the positive side faces outwards towards the back cover of the fob.

Remove the Old Battery and Insert the New One: Carefully remove the dead CR2032 battery. You may be able to gently pry it out with your fingernail or the tip of the screwdriver if needed.
