What does the Nissan Intelligent Key™ buzzer mean?
If your Altima is equipped with the Nissan Intelligent Key™, you’ll find that the car warns you if you’re about to lock the key in the car. If the key is left behind when you exit the vehicle, you’ll hear a buzzing noise when attempting to lock the door. That’s your signal to retrieve the Intelligent Key™. Make sure you get both the car key and the Intelligent Key™.
