I own a 2002 Pathfinder SE that I bought used. There was never any mention of keyless ever on it. Is aw all the posts for programming fobs to the car but I can't tell if I have anything in the car to make it this simple? I looked in the fusebox where it said keyless and there wasn't anything...so is it possible for me to do this or do i have to buy a whole thing? Also how much would it cost to do it through a dealer?
