Question about 2004 Nissan Maxima
Yes this could be caused by the Nissan NATS system. Your keys may need to be initilized for the car. Is the SECURITY light on steady, or is it flashing?? Check it. If its steady, than the NATS locked you out and you will not start the car. If its flashing, than NATS should be all set and the car should start. MAke sure, that you are using initilized keys.

Tips for a great answer:
A faulty engine coolant temperature (ECT) sensor. Compare the ECT with intake air temperature (IAT) on a completely cool engine with a scan tool. The ECT should be within 3?°C (5?°F) of the IAT. If not, refer to DTC P0128 .
You need a scan tool to check this stuff !
