DIY Program 350z HR & DE Immobiliser Keys

[cs2000]

So rather than sell the service, since i no longer own a 350z, i thought it about time to share this info. We all know the pedal dance to pair keys to the BCM which allows the button on the keys to unlock the door, but if you had a brand new key, or had lost them all, you had no way to add new keys to NATS so they would actually start the car, well, with a bit of software and a cable, now you can. Last time i checked, prices from local specialist locksmiths and Nissan main dealers range from £110-£200+ depending on your location and if they have to order you a key. Nissan also have to send off for the codes they require to program to NATS from Nissan HQ which takes a few days.

 

Software Needed

You will need to purchase whichever Nissan Datascan version matches your car, this software is amazing and is similar to what the Nissan Consult II offers, it can read modules normal OBD readers cannot as it was coded to replicate Consult II features.

Nissan Datascan II (For DE Cars) £29.50 - https://nisscan.com/product/nds-ii-windows-pc/?v=7885444af42e

Nissan Datascan III (For HR and Rev-Up Cars) £36.00 - https://nisscan.com/product/nds-iii-windows-pc/?v=7885444af42e

Hardware Needed

You also obviously need a new key blank with an immobiliser chip and a OBD cable, the maker of Nissan Datascan says to use Vag-Com cables. Both of these items can be found in many places online, but here are two examples. You will also need to have the key cut to match your ignition barrel.

Get your NATS PIN Code

1. The pin for many nissans upto 2008 will simply be 5523, if your immobiliser has an A in front of the serial number, try this code first. If it fails, we can generate the key

2. Run the ICU to NATS Pin Calculator software and you will see an example of the sticker we need to find.

3. To access this sticker, you need to remove the 4 screws underneath the lower steering wheel cowling and you should be able to bend it back far enough to see the ignition barrel, if you use your phone camera you should be able to get a picture of the sticker located on the top which should look very similar to the example one shown.

4. I have done a few of these and the positions of the numbers does seem to vary, so try a few numbers that you see and get a few potential codes ready to go. The numbers will always be the same length as shown in the example, even if they're in different places!

5. Simply enter the numbers in the rough locations shown and you will get a NATS PIN.

 

Key Coding Process

1. Connect the OBD cable to your car and open the NDS software

2. Turn the car to ignition on

3. In NDS, select the "ECM" tab and click Connect

4. Once connected, click "Work Support"

5. Enter your NATS code in the "Program Immobiliser Key" section

6. Click "Program"

7. The software will warn you that all keys will be erased. If you have a working key(s), make sure you have this with you as you will be re-adding all keys back into the ECM. Click Yes to continue.

8. The key currently in the ignition will be programmed, you will then see a message. If you have more keys, follow the instructions shown.

• Turn the ignition off
• Remove the key,
• Re-insert the key you just programmed
• Turn the ignition to on for 5 seconds
• Then back to off for 5 seconds,
• Then insert the second key
• Turn the ignition to on for 5 seconds
• Then back to off for 5 seconds,
• Repeat for as many keys as you have

9. If you have no further keys, or have registered all the keys you have, simply follow the message and do the following

• Turn the ignition off
• Remove the key,
• Re-insert the key you just programmed
• Start the car

 

SImple as that! New keys added to NATS for under £50 all-in!

Thanks for sharing this I've already got data scan but was very unsure of how to do this.
