Mine was working but I tried doing it twice since I got home from my drive.
I went for another drive, came home. When I turned my car off it has a screen on to start engine and pre condition car. I believe aslong as that screen shows then you are good to go. It stays active after the car is turned off.
I then went in my house and tried first with my phone and it worked flawlessly. Then again with the remote and also worked. =)
Couldnt start it before work the next day though.
