The SKREEM is not telling the ECM to start the car. THe three starts and nothing is a diagnostic put in the software so you can tell what is going on.

SO, either the SKREEM is bad OR the SKREEM is good but it can't read the RFID chip in the key, because the RFID chip is bad or missing.
The chips do not likely go bad, so unless you tampered with your key FOB or changed the FOB, I'd say you need a SKREEM.

There SHOULD be a message in the odometer window, "Start Error" (or something like that) when this occurs but most never mention it.
In any event, this is not an easy one to prove without ordering a SKREEM and putting it in - to see if that fixes it. Problem is, the SKREEM is now a $700 part.

If you have the car towed to a dealer, the cost of this will rise to at least $1000, perhaps way more, as they blunder and stumble and try to diagnose what they do not understand.
