I use all three, the fob, the keypad and the app on my phone. I only use the keypad if I need to run out to the car to get something, and when I drive the car the fob stays in my pocket, I don't like leaving it in the car. I use the ford pass app to remote start the car when I'm about to leave work because my key fob is in my pocket in the locker room and the locker room is out of range of the car. Remote start from the fob only works in about 250' max and has to be line of sight so I have to use the app to cool off the interior in the summer or warm it up in the winter.
