Dude. I had a Chevy Equinox that I brought to a guy to install remote start on my car. It was a few hundred bucks and I got a new key that if I was within range I could use to start the car. No internet involved. I got rid of that car and now have a Mercedes S class and I have to use a phone app to remote start the car. The only improvement from using the app is I can start the car from much farther distances than before (anywhere technically). However the app sucks, has a monthly subscription fee, and likely is not secure. Everything about the experience is worse than what I had in a car that cost a third of the price. It's very annoying.
