    Once into the NATS/IMMU, and after entering the 5523 code, it wont let me in any further. Any suggestions?

     That pin code 5523 may be wrong for that year model car. If not you may have a bad immobilizer unit. I have not had any trouble doing Nissan.

     For this model, you'll have to obtain  the 5-digit number code from the BCM to convert to the 4-digit pin. Can your tool obtain the 5-digit number code?

     Yes I believe so. When I go into PIN read: I get   23070   Can you explain to me how to convert to a working 4 digit? Thanks!

        Thanks Costee for some good info. I think I'm heading in the right direction, but just not there yet.I found the code converter in a different thread, One of the 4 digit codes it gave me,works, but after IMMU initialization, I leave 1st key off for 5 seconds, then to on(not running) for 5 seconds, then off & remove key for 5 seconds, then insert 2nd key(original) and turn on for 5 seconds, then off & remove for 5 seconds. I can then insert new key,& it will start the car, but the red security light is on, I can shut off & start the car several times, but if I switch out keys, or don't start for a couple of minutes, then the new key will not start the car. The original key still works, but cannot get a 2nd key reliably learned to the car. Any help would be great, Thanks in advance!!!

    I believe the pin used is 6656. You may start the process with the original key. After initialization by the pin proceed in the following manner:

    Turn ignition key (1) to the "OFF/LOCK" position and pull it out. WAIT AT LEAST 5 SECONDS.

    Insert key (2) into the ignition and turn it to the "ON" position. Do not start the engine.

    Wait at least 5 seconds (the Security Lamp will flash 5 times, then it will stop).

    Turn the key to "OFF/LOCK" and remove it. Key (2) is now registered.

    Insert key (1) into the ignition and turn it to the "ON" position. Do not start the engine.

    Wait at least 5 seconds (the Security Lamp will flash 5 times, then it will stop).

    Turn the key to "OFF/LOCK" and remove it. Key (1) is now registered.

    Re-insert key (2) and turn to the “ON” position for 5 seconds.

    Wait at least 5 seconds (The Security Lamp will not flash during this 5-second period.)


    Turn the key to the "OFF" position. [This will take the system out of the key registration mode.]


    Wait for the Security Lamp to start blinking (approximately 5 seconds).


    Hope this helps.

    It could be the transponder in the new key is bad or not present check the transponder,
    and possibly change to a new one I hope it will work
