Any auto computer gurus?

Just talked to a friend of mine.
He has a 2004 Avalanche. very low miles around 10,000. believe it has passlock 2.
he thought the battery was dead and disconnected it and tried a fresh battery. guess the truck sits for extended periods with out use.
it won't start, starter won't even kick out the bendix or try to spin. The pass lock light is on steady on the dash. He tried to do the re-learn, and the light won't go out. the dash lights stay on constant even with the key out of the vehicle. the power windows will not work with the doors closed, but open the doors and the windows and locks work. he tried reading the pcm codes and the pcm will not communicate with the scanner. everything I see online says the passlock disables the fuel system, can't find anything saying it disrupts the start circuit. there is lots of people out there with passlock problems. Anyone have info or have had similar issues TIA
He is thinking he will have to get it towed to the dealer, and just bend over and take it like a man.
don't ya just love technology?
