How do I replace the battery in the 2013 Malibu RKE transmitter?

Press the button on the transmitter to extend the key blade, then remove the battery cover by prying it with a finger. Remove the old battery by pushing on it and sliding it toward the key blade, then insert the new battery with the positive side facing up and push it down until held in place. Replace with a CR2032 or equivalent battery and snap the battery cover back on. (Page 40)
