Dead battery in the Key fob. Or the car battery is dead. There should be a slot on the lower left side of the dash. You slide the fob in buttons up key chain out. They had allot of problems with that system in 2008-2009.

Your key has a code on it or number.Your ignition is not reading your code.Go to dealer and try to get a new key.

You should first fill the transmission fluid to the correct with genuine Nissan Matic J Transmission fluid and replacing the transmission input shaft speed sensor. Its costs approximately $113 at the dealer for the sensor.

make sure your backup lights are coming on. if the backup lights are working when in reverse then most likely you have a bad camera or loose connection. also may want to check for power to the camera ( fuses/circut).

"If you have the airbag light, it will show steady for a few seconds (the manual says 7 secs) after you turn the key from off to on (but not start) and then start to flash. Here is how to reset it:

1. Turn the key from off to on.

2. Watch the airbag light closely. It will stay on for a few secs. and then as soon as it blinks off (the start of the flashing), turn the key off instantly.

3. Count to 5 (1 Mississippi, 2 Mississippi . . . .)

4. Repeat steps 1-3 two more times until you have done the cycle three times.

5. Now turn the key on and watch the light. It will start blinking in a different, slower manner. This is diagnostic mode. You can watch this for a little while, no hurry.

6. Now turn the key off again, Count to 5 like in step 3 again, and turn back on. If the procedure worked, the airbag light will not be flashing.

If it does not work the first time, just repeat the steps again."

That light is the security light. If it stays solid red it goes into anti theft mode and likley won't start.

my airbag light is blinking . can i reset anything its a04 nissaun armada

when the airbag light is on it means a fault has occurred in the system and the airbag diagnostic monitor has disabled the system, the most common problem that turns the light on is a break in the connection to the steering wheel mounted airbag, this is due to a rotating ribbon contact that breaks under the steering wheel that connects the airbag to the wiring harness and the diagnostic monitor, the part is called th clock spring contact, a coiled up ribbon electrical contact that turns with the wheel.

Here are the instructions to reset flashing airbag light, the instructions are for an Armada but I believe it will work on all Nissan models of this period. It wont hurt to give it a try. If that doesn't work you may have a problem that should be looked at by your local Dealer.
