Yes when i called to ordered the pcm they asked for the vin then ran it and told me it was a valid vin ! The predetor is reading the vin it shows up on the screen and it is the right vin!

most likely locked pcm... invalid key means it's an invalid seed key... the key to unlock the pcm... it's not a standard gm key....
looks like you're SOL....

When I got my Predator and was fixing to start bothering
the PCM, first thing I did was get a spare PCM. I has the
dealership do an in-car reflash to stock / match VIN. It
cost me half an hour of shop rates. I had mated the
Predator to the original PCM and the replacement worked
fine. Maybe you need to do this, maybe the place that
sent the PCM just missed something that happens
"naturally" when you use the TechII at the dealership.
Of course if you wanted some non-stock-ness that is
in the new PCM that'd be flushed. But id it's stock for
stock then give this a try (if the vehicle can make it
to the dealer with the PCM in it, and this is only an
access problem).

I had to have a service department friend help me out on that one.
I think it's because when you get a stock PCM, at least from the dealership, it's a blanked one cued for a base tune to that particular VIN. For instance, I have a generic manual transmission silverado pcm (stock generic PCM), but it was loaded with a base c5z tune because of VIN via their fancy equipment. PITA to tune? You betcha... and I'm still dealing with computer issues.
I hope your troubles aren't like mine.
