Have you done a relearn on the pass-key?
GM PASS LOCK RELEARN- Ignition to "run" position, try to start and let key return to "run" position
Approx ten minutes security light will go off
Turn key "off" and wait 5 seconds
Repeat 2 more times for a total of 3 relearns.
Turn key off, then start it

You are at the point of needing to read any stored codes, even if you have to buy a scanner to do it. Post all codes that come up, and if you can all freeze frame data.
