Hi, I bought a new Nissan Key for this Altima and when I tried to program it it asking me for a pin. Ive erase the original key and  after I erase the key it takes me to a screen and on that screen is shoes two items. one is filled out key id and below that is ask for a pin. how do I get this PIN number?  above these two places it shows a 5523 number but if I use that as a PIN number it tell me its wrong. so how do I get the pin for this car?
