I've seen some of this liquide ice defroster stuff will that keep the ice out of the button and locks on the doors?

You can use spray silicone to keep the seals from freezing. I treat all of my seals at the beginning of every winter and my doors and hatch don't stick at all regardless of how much ice there is around them. On the switch, you might be able to get some WD40 inside there to keep the water out, thereby keeping it from freezing.
