Default Immobilizer light flashing...starts for 1 second then dies

My light on the dash that shows the car and the key (not sure what its called) is flashing. The car was running fine yesterday and now this morning for me it will start for 1 second and then die.

Does anyone know what the cause and fix of this is?

Greatly appreciated.

Immobilizer (anti theft) system is not recognizing your key and thinks the car is being stolen. Two things to try:

1. Do you have another key to try?

2. Put key in ign, turn to run but do not start. Leave it that way for 15min.

Maybe also disconnect battery and leave off for 15min, hook back up and try.

Crazy idea that's also worked a time or two: flip the key over and try the 'other side'. It may position the RFID chip in the key in better range of the immobilizer antenna to be successfully read.
If you post a question, post your solution!

There is a pick-up coil that encircles the ignition switch to be the antena loop to communicate with the chip in the key housing. If the loop is shorted or open, the imobilizer will activate. You may want to check the wiring. Its pretty fragile and the first place I'd look.
