Hello, i had a promised remote start installed on my 2016 Fiesta SE. when i took it home and put it in remote start , it timed out and stopped but the sync 3 stayed on. I took it back the next day and the checked it out and told me that Ford said that it was correct and that you have to go out to the car and open the door to turn off sync 3. My question is is that how it is supposed to work? I am skeptical.
