How do you change battery in Cadillac key fob?

To change the battery in a Cadillac key fob, first, locate the small notch on the side of the fob and use a flathead screwdriver or a coin to gently pry it open. Once the fob is split, remove the old battery, usually a CR2032, and replace it with a new one, making sure the positive side faces up. Reassemble the fob by snapping the two halves back together securely. Test the key fob to ensure it’s functioning properly after the battery replacement.
