I got a remote start/ keyless entry installed on my 2004 FX4 Supercrew, and I'm having a problem with it. When I put it in grear, all 4 doors lock. But if I am alone and just open the drivers door, and its the only one unlocked, the new system makes me unlock all the doors before I can lock the drivers door.

So what I want to do is make it to where all 4 doors unlock when I put the truck in park. Does anybody know a way to make this happen?
