My daughter called tonight with this question-her Dad called a mechanic friend-he checked around for an answer--this is the battery in your remote keyless entry--the thing on your keyring.
To change the RFA (Remote Keyless Entry) battery in a 2003 Yukon Denali, first, locate the key fob and use a small flathead screwdriver to gently pry open the fob. Remove the old battery, noting the orientation, and replace it with a new CR2032 battery, ensuring the positive side is facing up. Snap the fob back together and test the remote to ensure it’s working properly.
