remote start keyless entry help

I have posted this before but it didn't make sense to the reader. Hopefully I cleaned it up a bit. I installed a remote starter with keyless entry. My truck had a factory keyless entry system that would arm the alarm when you hit the lock button twice on the key fob, also the horn would beep to let you know it's armed/locked. My question is how do I get the remote start/keyless entry to do that, so I do not have to use the stock key fob to arm the alarm? I have the lock/unlock pulse hooked up inside the door just after the switch. Do I need to move this to the BCM to solve my problem? Also, does the factory double pulse unlock (key fob) work off of the one wire at the BCM? Please help, this has been driving me nuts for days.     2002 GMC Seirra 1500.

What make and modle of your keyless entry/RS

it's an ultra start 4500, I don't want to use any of the alarm features.
