Intelligent key port aka fobgina question

So obviously the fob does not need power in order to start the car. So what's left that does require power? Well, you mentioned pretty much all of them above. But here's the rub. You can send power to a fob with a dead battery by sticking it into the fobgina, right? Well, you're not going to remotely lock/unlock the doors or activate the emergency alarm while the fob is stuck inside the fobgina. Or to put it another way, by sticking your fob into the key hole, it'll power up the buttons on your fob, but your access to those buttons will be obstructed by the very fact that you have inserted the fob into the key holder. So what's the point of even having a fobgina to stick it into? As I said, you don't need it to start the car up.
