There are multiple threads, or at least hijacks of threads, on this topic.
You are trying to take it a step further, rather than complain, you are trying to hack the ignition switch, for want of a better description.
The key switch is required to unlock the transmission shifter and the steering wheel, so ignoring the Body Control Module that will not like what you are trying to do, that is the first "mechanical" obstacle that comes to mind.
Additionally, there are none of the safety/theft features built into the Twins to prevent anyone from jumping in your truck and driving off if you solve the mechanical problems.
This may sound like I am being a jerk, but the fact that you thought you could just use the remote start to enable a keyless operation of the Twins tells me you don't have a good enough understanding of the differences between the two systems to undertake this hack.
(FYI, I don't have the understanding of the keyless system to undertake the hack, but I know enough about the basic key-required system to recognize the significant hardware/software hurdles that will need to be overcome.)
Perhaps a Ridgeline is in your future.
Just looked at the Ridgeline Owners manual. It takes 9 pages to explain how to use the remote on the Ridgeline. Not sure how long it would take my feeble mind to figure all 9 pages out. I figured out my truck key without ever opening my owner's manual. Guess I ain't smart enough to drive a Ridgeline. The Twins are in my future.
