If Last Order tried to track the signal from the TV broadcast what would she sense? Same question about tracking where the electricity for the door locks is coming from.

Annnd also can she alter the electronic locking mechanism to lock the doors/keep them open permanently?

EDIT: The window with the view; is it electricity powered or does it just seem like a window? Just incase Last Order would be able to tell if it was fake or not in a heartbeat.
