Viper
Had mine installed about 2 months ago. Also came with remote starter. I love it. They will work with factory keyless. I can start my truck as im brushing my teeth, get my boots on, and she's had the minute or two to wake up before i get in it. It can also be programmed to operate many other functions in a vehicle, such as heated seats, rear defogger, and so on. I'm pretty sure there won't be any factory options that it will operate on our trucks though, but i'm pretty sure aftermarket stuff can also be made to work, depending on what it is and how it works. Another awesome feature, is the automatic turbo cooldown. I pull in the driveway, press 2 buttons, take my key out, and hit the arm button. Truck shuts itself off after 1 minute... but can be changed to different intervals.
