I had an expert named Brian that lives in Florida, and owns many crossfires come and look at it, but he did not bring his specialized diagnostic tool, so we were unable to check for any codes. He’s thinking it might be the central locking pump, because the key is not being recognized by the car, even though everything was reprogrammed. Is this a possibility? Also, the RCM was working fine. I’m at a loss. I want to get her back on the road but I have no idea where to go from here. The battery has been checked. The starter has been checked. Everything normal has been checked. The fuses have been checked . Please please help me.
The key is recognized by the SKREEM and only the SKREEM. The ECU takes instruction from the SKREEM as to start or not start. The central locking pump won't prevent the starter from engaging OR the 'car not recognizing the key'.
Who did the 'reprogram" on hte SKREEM and ECU? What did they say they found? I ask, because the SKREEM fix is NOT to reprogram it but replace it with new SKREEM or do the 'delete' to where the SKREEM no longer reads the key.
NOW DO THIS: Get in car, turn key to start - does the starter engage or not?
IF NOT: Release key and let it go back to ON, wait 45 seconds. Does engine fan start running very fast and loud?
If fan runs fast, it aint your SKREEM.

I have asked several questions, if you respond to ME, please answer every question, failure to do so wastes my time and yours, we cant diagnose a car from a distance without detailed information.
