I have been looking for a 2-Way Remote Start System for some time for a couple of reasons. 1.) Convenience during winter, and 2.) We lost a spare car key and they cost $450+ each so this seemed like a perfect solution. I've had this product now for about 5 months and it's fine except that I'd have to question its maximum transmitter range of 3000 feet. I work on a college campus so I'd suspect that the frequency rate is weakened when your vehicle is in the middle of 500 other cars because I've never been able to get it to start unless I'm more or less 200 feet away. Again, this 3000 feet transmitter range is likely accurate in the event that you're in an open space. A little disappointed about this.
