A friend of mine is having some 4wheel drive issues and has to take his 05 in to the dealer. He's running smarty also. He's concernd about his key count. Is there any way to up a key count. He says he thought he read once where there was a way to up a key count. I've never heard anything like that,but I told him I would try to find out something. I heard the noise his truck is making, there's some serious clunking going on and it's only in 4wheel drive.
