Well, the dealer got the PCM in around 1pm today. Spoke with service, who called me asking if I was "Close-by" to drop off my other key so they could program the new PCM. I asked why they didn't ask me for this when they ORDERED the PCM, as I could have dropped it off last night. They claimed they didn't know they woul need both keys. So I told them to cut a new key!!! To which they said, "Oh, I wonder if we could do that?"
OF COURSE YOU CAN MORON!!!!! I didn't say that, I just wanted to. I kept calm, and polite, and asked if I could bring my other key in when I pick up the truck to have them add it to the new PCM, since the key they are cutting for me does not have the remote buttons on it, and my existing one does. AND we still don't know why the 4x4 doesn't work. Yippee!!!!!!!
