Just throwing this out there for anyone who doesn't know:

Every 01-03 Maxima uses the same PIN for the NATS. The pin is "5523". This is the default "master" PIN.

This means that you can use a BlaZt cable to re-initialize the NATS on any Maxima of those years. This is particularly useful for those who have to replace their ECU and don't feel like going to the dealership and dropping $100 to get the ECU programmed to their key/immo (or those who simply want to add more keys to their car).

Normally, the PIN is provided to you when you buy the car but most people lose it. Well, now you can finally add your own keys to the car and/or re-program a used ECU's to the car.

For those who don't know the PIN, the PIN can be decoded using a software called "Nissan SuperCode". The software requires the serial number from the BCM that the ECU came from. It will then provide the PIN. The only problem is that when you buy an ECU from a junkyard, they usually don't provide/know the BCM serial number from the car that the ECU came from. Normally, you'd have to go to the dealer so they can decode it, but now that I discovered this "master" PIN, you can do it yourself!

The following cars all use the same "5523" default PIN:

Nissan Altima 2001-2004;
Nissan Maxima 2001-2003;
Nissan Pathfinder 2001-2004;
Nissan Sentra 2000-2005;
Nissan 350Z < 2002;
Nissan X-Terra 2003-2004;
Infinity QX4 2001-2004;
Infinity QX45 2002;
Infinity Q45 2001-2005;
Infinity G20 2000-2002;
Infinity I30 / I35 2001-2005



I figured it is OK to post this here considering this info is readily available on the internet. If someone is going to steal a Maxima, I'm sure they can figure it out on their own.

 

Super!!Thanks for providing this information UnkleJoe. When I swapped my engine recently I had a no start and realized it was a NATS issue. For whatever reason my main key was no longer accepted by the system, but luckily my spare still is. I've been dreading having my wallet raped by the local stealership to program a new spare key, and you've provided a solution. I'm not very comfortable with electronics- the BlaZt cable attaches to the underdash diagnostic port and then to a computer, correct? How do you then program the new key?
Thanks!

 

No problem!

And yeah, the Blazt goes right to the OBD port and your laptop.

You then go into the NDSII software (comes with the cable or u can download it) and click "Work Support" and then click key program and enter the pin then follow the instructions.

Its pretty simple

 

does this work for 2k as well? cant get mine to start, mechanic says its the immobilizer...

 

Unklejoe, any suggestions on how this works on the 2000 Maxima?

 

Thanks a bunch UnkleJoe, I have been searching that info for quite sometime.

Now I can swap the ECU, reprogram the key and fire that biatch !

Wooooooohooooooo !

 

Today i tried for the X time to hook up the NDS II software on my maxima after swapping the ECU, but I got the same result, it doesn't work and the support on the NDS forum suck.

Today I've check on the NDSII page for the supported vehicle and find out the Frontier was supported, so I hook up the laptop and got the same result. Since the very beginning I probably have a faulty USB cable, anyway I ordered a generic supported/tested cable from e-bay hoping that it's going to make the NDS II software to work once and for all.

 

Bump.
Did anybody find out how this works on the 2000 Max? What's the "master" PIN, if any?
Unclejoe, any ideas?

 

I'm gonna get NDSII and try this out

Makin keys AWL DAE now.

 

Did it work for you when you swap the ecu? I read that if you replace a ecu or immobilizer module it needs to be initialized to be sync with each other and the NDSII software cannot do that. Thanks.

 

did it work for you? thanks.

 

NDS II works great, i program keys on 2000-2003 maximas very easy and i have a program to calculate the pin for the newer cars 2004+

It also works great for diagnostic work

 

Thanks for the quick response. Did you replace your ECU or immobilizer module when you programmed the key?

 

I'm not one to grave dig but I just want to know if anybody else has used this on their 02-03 maxima. All of the descriptions I see for the Consult-II scanners only support up to 2000. Hopefully someone can chime in on this. Thanks.

 

could this work on a 2003 350z??

 

If anyone still needs to do this in the future on a 2000 5th gen, I did it today using a PIN of 0000. Locksmith couldn't get me going last week and the 5523 PIN did not work as other's have reported. While I can't verify that PIN 0000 is a universal thing at this point, that's vague enough that I suspect it might be. I was at my wits end and just tried it for the hell of it like working on a computer and once that security light went out, I nearly crapped my pants. Took less than a minute with the correct PIN. Hope this helps someone!
