I bought my truck used this passed week and wanted to say thanks, because when I bought it, the used dealer didn't have the code for the door. I was a bit bummed out. He told me that the dealer could do it, but there was no way I was going to pay $80. I following the instructions in this thread and it worked like a charm. Thanks a bunch guys!!! Oh, and getting the rear seat back off wasn't that bad at all.
