I installed a Viper Smart Start system into a 2011 Subaru Impreza. Now my customer is able to Remote Start his car as well as lock/unlock his car right from his Iphone 5S. The smart start system will allow you to remote start your vehicle from virtually anywhere in the World. This system works with most smart phones and can be added on to even your factory remote start system. Take a peak at this video. It will give you an idea of what you can do right from your phone!
