This would be cool
I could register my cell phone as a fob and carry no key at all

Not sure if they could get it to detect where the bluetooth device is like they do with the fob ( if inside the car don't allow touch unlock from outside ...... )

I love it that I can't lock my fob in the car
dont need $200 a year onstar for that
