What happens if the iPhone runs out of battery? The site says it still works if you have "lost power", but I assume this means in the household?

I assume you could still use a key. Nothing seems to be covering the deadbolt lock on the outside of the door. I have the same problem with two-factor authentication though, I guess you'll just always need a backup.
