That’s not what I read. Starting the car with the key fob or previously known as “remote start” which you had to pay like 800$ for, is what the subscription is about.
You can still open the car with key fob in hand. And sit in and start the car with key fob in pocket.
Sometimes this can be done via cell phone app. And there is always a monthly subscription for this option.
But no it is not a monthly subscription for starting your car with your key fob in the pocket.
