Is there a app that will let me unlock my car doors.
I remember reading on this a long time ago and I think it requires infrared which I know the droid one doesn't have, im sure the other android phones don't have it either. Due to that its impossible.
Yes, there is on-star and there is a new Viper alarm that was just released that will allow this (android and iphone apps). You will be paying a monthly service though....but you can unlock/lock arm/disarm start your car from pretty much anywhere.
