-
Remove the Old Battery: Take note of the orientation of the old battery (positive side up or down). You may be able to gently pry the old battery out with your fingertip or use the tip of your screwdriver to carefully lift it out of the compartment. Dispose of the old battery responsibly according to local regulations.
-
Insert the New CR2032 Battery: Take your new CR2032 battery and insert it into the battery compartment, ensuring that the polarity (+ and – sides) matches the orientation you noted when removing the old battery. The positive side of the battery is usually marked with a “+” symbol.
-
Reassemble the Key Fob Casing: Carefully align the two halves of the key fob casing and press them firmly together until they snap back into place. Ensure that the casing is securely closed and there are no gaps.
