    2006 300c ngec no crank

    So I was working on a 2006 300c with ngec3 the car drove fine. I dataloged the initial drive and once I flashed the ecm and tcm I also did a tire size change the car wouldn't crank. I did a write entire back to stock and still no crank. unplugged the battery and everything and still nothing. my last attempt was to disable the skim and that didnt do anything. has any one had this issue before?
    Update: Its now throwing a p0513 incorrect immobilizer key.
