I'd tend to agree it is the ignition key assembly.
Had a dealer argue with me for 3 months, "oh those never ever fail" until I just bought the thing and installed it myself. Prior to swap, it might have started if you wiggled it and held your nose just right. Afterwards, fixed.
If you have a wiring diagram and a cheap meter, you can check to see if it is getting the signal... dunno on yours how the transmission interlock inhibits key signal though.
