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.
1. Thank you for responding.
2. The SKREEM is not recognizing the key, I suppose. Josh Chase is the one who did the SKREEM/ECU/key back in May. . I believe he reprogrammed the key to the new SKREEM, but I can't say for sure that it was replaced. I was under the impression that it all just needed reprogrammed, but he does these fixes every day, so I'm assuming he knows what he's doing. I tried starting the car last night, but I'm pretty sure the battery is dead now, because neither the interior lights nor the radio would come on, where they used to work fine, even when the car wouldn't start. The engine fan never ran fast/loud during any point of trying to start the car. I'm at work at the moment, so I can't try to start it again until I get home, but I'll do the 45 second thing....I seriously doubt anything will work though.
Also, I should mention, the keyfob has never locked/unlocked the doors, ever....I always had to do it manually with the key...not sure if that makes a difference or not.
