DIY: Replace dreaded steering-lock on 2009s and early 2010s.

That was a lot of good advice, thank-you ... but i'd still like an old lock to play with.
What do racers do about this "lock" nonsense ?

Maybe Chrisslicks had the answer within the push button switch:

Sooo, I can turn off accessories myself so do not even need the "lock" mode on the ign/start button. "Accessories" will do fine.

Can that "lock" mode be deleted easily?

(It's then easy to fit an ignition or fuel pump delete switch..hidden)

To remove the stock starter button would be a bit of work, the button in the stock setup is just a contact closure which sends the press signal to the BCM, the BCM decides what "state" the car should be in, e.g. ACC, ON or START and sends a start request to the IPDM via the CAN bus. The IPDM turns the ignition relay on, and turns the starter relay on. When the BCM feedback determines that the engine is running it sends a stop signal to the IPDM for the starter relay. It seems like it should be possible to just re-wire the relay's to manual toggle switches/buttons instead of the IPDM, same for the fuel pump relay. I think you would also have to deactivate the vehicle security system using UpRev. If you did that then the steering lock could be removed as the BCM would be out of the loop for startingthe car. The BCM might be unhappy, but to what degree I'm not sure. I guess it depends to what degree you need auxiliary systems like windows etc.

UpRev has a specific setting called "NATS off" you can set in their custom ROMs, which completely disables the Nissan Anti-Theft System code. Apparently only Pro-Tuners get this feature, not regular Tuner-licenses. Other than that little bit, the primary different between Tuner and Pro-Tuner is that Tuner is limited to one VIN, whereas Pro-Tuners can work on multiple cars. Most likely if you have a regular Tuner license, you can just go to a Pro-Tuner w/ the datafile and have them toggle this one option for you if you want, and then still edit the rest via Tuner and upload.

With NATS off, I would expect nothing about steering lock (or anything related) matters anymore and the equipment can be removed. The car also doesn't care about key-marriage at that point, although I'm not sure whether that means "any Nissan key in range will do", or if you don't have to have a key at all to start the car.
