I suspect if you can find a scan tool that can access the anti-theft system (most commercial scan tools cannot) you'll find a code indicating that two keys are being seen by the PATS/SecuriLock system at the same time. The system will lock out an engine start if it is getting more than one signal. Sounds like the temporary fix would be to remove the PATS/Securilock bypass kit for the remote start.
