    The car is not recognizing your key.  Car thinks it is getting stolen.  Lock the car and open it manually with your key.  Put key in ignition, turn key to ON (do not start) and wait until the anti theft light goes off.  Turn key off, wait one minute and try to start.  No luck, get it towed to a competent garage or a dealer.
