I have a Code, my mother has a code, my step father has a 791xv on its fourth month, and I have two clients who have the 791xv I've installed and yes I make service calls to change the battery and chat it up. Super service comes with the install.

I replaced one at the six month mark. But in your defense the 2way was installed because it wasnt a dd and he wanted to remote start to maintain the battery without sitting with it for 30 minutes so the remote probably had light use. My other client probably changed it himself.
