yesterday it was my birthday and as a gift my parents agreed to get me a remote start. i have an 06 Sport and i have the factory alarm with a remote start. its the Viper 160xv system. it comes with two new key fobs that you use. open and locks doors, turns on the car and an aux button. works great and im in love
Edit: yyou only use one fob, the other is just a backup. the factory fobs are useless at this point.
