After tearing the lock apart and depressing the buttons, mine would cycle to on but it wouldn't start. I think the only option at this point is to replace the lock.

If it's not, good luck bartering with Nissan. The dealer is going to want you to pay for the entire repair upfront and then you have to call Nissan NA and open up a case.
From what I've read, sometimes after several weeks of b!tching they reimburse you for about half of the repair. Or you can get a new steering lock and replace it yourself.
I drove down to Courtesy Nissan and paid right at $700 for the ESCL. I called 2 dealers and both estimated about $1,500 if they fixed it.
