What this Message Alert Mean?

its not a battery charger, quite the opposite actually. The only time you use that is when your key battery is dead, to be able to start the car. I hope you havent been using it as a key holder! It will actually drain your keys battery if the battery has juice. And that icon means the key has been removed from the sensors range, so if you were in the car with the key, you battery is low or dead.

Funny u say that... my dealer told me that putting it in the holder recharges the fob. N it only needs 15 minutes of charge in the holder like once a year. That was wat I was told. And the battery itself will sustain 3 to 5 years.
I better look it up in my manual I guess?
I dunno y my dealer would tell me that if he wasn't sure?
But then that was my altima. My its different on a z?
I doubt it... well I'll go check

OK, after digging around the car user manual I found that in my particular situation, the "NO KEY" warning happens as a result of a driver apparently NOT having pushed the power button long enough so that the power button actually causes the car to enter the all power-off "LOCK" mode and instead the car made it only to the power-on "ACC" mode.

The engine was off but the car was still under electrical power. The bell dings and the lit "NO KEY" guage alert is the warning for that condition if you try exiting the car as I did.

So make sure when you intend to exit the car and you push the power button to turn the car off that the light around the power button circumference says "LOCK" and not "ACC" otherwise this audio and visual alert will happen.
