I currently have a 2014 Santa Fe sport and am really thinking about upgrading to the 2016 Sorento SXL V6 with the tech pack. I like the remote start with the smartphone app (Hyundai Bluelink). If I understand the website for Kia, the remote start for the Sorento is a dealer add on and requires a second key fob. Can anyone confirm if a second/aux key fob is needed? Thanks
