I had best buy install this in my 2003 Acura Tl and it works fantastic. I start my car from the 3rd floor of my work across the parking lot, I've started my car from inside Sam's Club, I've even started my car from a block away on a run and it works flawlessly EVERYTIME. Amazing. It has a pit stop mode so I can run in and get a coffee from the donut shop without worrying if my car gets stolen. Two way communications ends me having to go out of my house to make sure if I really turned on the alarm. My favorite part is that it replaced my old remote, no need to carry the original remote as well.
