I have a 2008 QX56 with intelligent key. This morning I can not start the vehicle. Has anybody had this problem? The remote will lock and unlock the doors, but the ignition switch will not rotate from the "lock" position and the dash light flashes the car and key symbol. It is Sunday and Infiniti roadside assistance says they will tow it tomorrow to my dealership because they need a dealership signature to drop off the car and nobody is there on Sunday.
