I didn't run codes. I'm thinking of calling a company to try to reprogram my key. When I lock the car, it doesn't make the alarm beep. Do you know anything about the sound inside the car that Nissans make? In my case after I shut off the ignition switch? I never heard this sound in any car before. I also realize a red light that flashes under the steering wheel when this happens.

I think it's actually the immobilizer that we are talking about here, not the alarm.

(Don't forget that you can toggle between having the beep or lights flash when locking the car. If neither are happening, then yes, that should help narrow things down.)

Relays and servo motors behind the dashboard can make a noise when powering down, but obviously the noise is something new.

No smell of gas after repeated unsuccessful start attempts?
That can compound the problem and still prevent a start if the initial problem was just a temporary glitch.

I'd have been inclined to remove the negative cable for a few minutes in the hope that would reset things.

But it will probably need a code reader cable of checking the immobilizer system (not a basic OBD-II scan tool).

Not sure about the flashing red light under the dash.

Let us know how things work out.
