The long range version also works with your OEM keyfobs same as the non-long range version (3 lock key presses to start).
It just comes with 1 extra keyfob for the long range, which you can choose whether to use or not.
I think this is pretty cool... most of the time I won't need the long range remote so will leave it at home, and use the factory keyfob to remote start it.
When I'm going somewhere where I will need to remote start it from a distance (parked up at the ski hill, at a mall surface lot, from the office etc) I can take the long range fob, start it from a distance, and have it warm when I get to it. In fact, for the office, I could even just leave the long range fob in my desk and start it before I leave at the end of the day.
My only wish would be that it could start the heated seats, heated steering wheel, and window defroster. Some OEM solutions do this when it detects the temperature is low enough.
