I'm look'n for one as well. I hate that it shuts off the vehicle whenever you open the door. That sucks.
I went on YouTube to see what they had for 2016-17s and watched a install video of a shop in Georgia. They use the OEM Key Fob.
You press the lock button three times and it starts the truck. But it still shuts off when you unlock and open the door.
I'm going to check with my local shop this week and see what they have/use. Won't do it if another key fob is needed. I'll wait until somebody figures it out, especially don't want the engine shut down whenever the door is opened.
