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
Check fuses both in the car and under the hood, Have PCM scanned for codes, if the ABS light is on you have stored codes, scannibg will pinpoint these, and scanning will find out if the light control, or body control modules are OK.
