My daughters 05 would not start - several forum members were certain it was a bad SKREM module. One member suggested I contact SOS Diagnostics for help. I did just that and SOS said send them the SKREM, PCM and keys, they would check them out. I did just that, SOS provided me with a new SKREM, programmed for the car and ready for installation. Car starts and runs great - thank you all for participating in this forum.
