"the extra distance just means your heat is on that much longer before you get in ;)"

But, how do you know how far you are from your car (i.e. how do you know if you hit the button inside of the mall that the car actually was reached?)

I'll ask them all that later - this is why I'm going to Rich's. They aren't the cheapest around but they sell all quality stuff and will do a good job with the car (heck, maybe Joe Perry will be there and I'll get to chat with him too!). I can kill 2 birds with one stone that way :)
