Thanks to the input I got on my other thread, I was able to make some progress on my '08 Infiniti EX35. I have a friend with a professional shop who recently acquired a Foxwell NT919BT that allowed me to reauthorize the keys and write the updated VIN to the replacement ECU.

While the car is now allowing me to start the engine (which it would not do at all before), but it dies a split second after it catches. I've done some reading and it seems like there may still be an issue with the security, but I'm not entirely sure.

I guess at this point the longer version of the story is necessary, but I'll try to keep it as brief as possible.

• The car has not been running for at least 2 years at this point.
• It started with a failed window regulator, parts were unobtainable for ~8 months.
• After replacing the regulator, I started getting electrical issues
  • Car went into limp mode because the temp sensor was reading over 400 degrees F.
  • Replacing the temp sensor fixed that issue, but I started getting rough running and a cam sensor code
  • Replaced sensor, issues persisted, ran a full trouble code clear on all systems including BCM
  • Car would no longer start and run, would just crank
  • Took the car to the dealer and they diagnosed a failed ECU, according to the tech this is common with these cars if they sit for over a few months.
  • Replaced the ECU with one that was supposed to be pre-encoded with my VIN, which is were I started my other thread at.

I'm not sure if I got a defective refurb ECU or if something is still wrong with the encoding between the ECU and BCM. I've read some conflicting information on whether or not coding the keys and setting the VIN in the ECU using 3rd party scanners like the Foxwell is sufficient or if I definitely need to use the Consult R2R platform. As mentioned before, I do have a J2534 passthrough. I just don't want to spend the $55 on Consult if that's definitely not going to work.

I posted this in the Infiniti sub but didn't get any responses, so I wanted to try my luck here

I have an '08 Infiniti EX35 with ECU issues. Long story short, I was supposed to be getting a used ECU pre-coded with my VIN but it wasn't coded properly and now my immobilizer is pissed off. My local dealership is useless. I told the service tech about my issue and he said "hold please" and transferred me to a car sales person. I guess they're notorious for this because the techs don't like working on anything out of warranty.

I already have a J2534 programmer that I use for tuning my Volvo and it should be compatible with Nissan as well. and I've read up on the process and it seems fairly simple. The only thing I see when looking into the Consult III software is that it does not support immobilizer unlocks. Is there a way to get an immobilizer unlock from anyone except the dealer?
