Next time, You could have just walked your parents (assuming you could call them) through downloading the app, signing them in, and remote open/start your car and drive home.
Well, as I’m thinking this over, this is all unless you had multi factor enabled.
Didn't know you could remote start the car, meaning like someone can remote start it and not be at the car, and the car can drive? I always assumed the phone must be on the driver at all times for it to work, due to bluetooth.
