I'm having some trouble with this as well.............
I am trying to program it so the doors unlock when I shift into park and am having no luck at all.........
My question is this......It says to hold the bottom of the lock/unlock button down........I'm assuming they are talking about the button that is on the door panel and that the "bottom" is actually the "UNLOCK" side of the button..........
That's what I am doing and it's not working for me.......
It's programmed to lock all the doors when shifting from P to D from the factory, but I want all the doors to UNLOCK when shifting from D to P......
