08 G37 no power/ no start
Hello in some need of advice.
I have a 2008 G37s 6MT twin turbo AAM.
I took my care in June of 2022 in for repairs due to leaking coolant lines to the driver side turbo. While at the shop mechanic stated he was having a difficult time getting the vehicle to start after fixing the original issues it had went in for. I have never had any issues with the vehicle starting before. it took this mechanic weeks to figure out what he thought was causing the issue. I had them check all the fuses/ relays as well as the steering column lock. They bypassed the clutch safety switch to determine if that was an issue causing the vehicle not to start, and it did not work. they stated it was a bad steering Colum look and replaced it (so they say) after replacing the steering column lock they attempted to re program the vehicle and were still not able to get it to start. They found out there was a BCM error code after changing the steering column lock and cleared the code. after the code was cleared the vehicle would start but, once you shut it off the code would come back the next time you attempted to start the vehicle. you have to clear the code from the BCM every time for the vehicle to start. at this point they began to think it was a faulty BCM, so they replaced the BCM with a new one and attempted to reprogram and start the vehicle only this time there was a communication code Between the BCM and the ECM. They were still unable to figure out what was going on. so, with no solution to the problem I decided to have my car moved to another mechanic shop for a second opinion the following day after they were unable to figure out a solution to get the vehicle started. While trying to move the car the next day the car had absolutely no power and the key fob stopped working. Once at the new shop we replaced the battery that was under warranty. when hooking the new battery up both driver and passenger windows automatically rolled down. we attempted to start the car and it would do nothing at all. the push to start button showed no lights dash showed no lights. even inserting the key into the key box did nothing. the interior lights and automatic seats still function but nothing else inside the vehicle will work. The car was also beeping when you attempted to roll the windows up. the only light that would come on the dash was the red key light. it would flash three times then turn off.
anyone have any theories or suggestions on what I should check or ask the new shop to take a look at.
also, this is my first time owning a G37 so I'm still learning all the ins and outs of the vehicle.
any advice would be greatly appreciated.

You do not mention what the codes are/ were, so...
I will keep this short...
If the RED KEY icon on the cluster is ON then IVIS (Infiniti Vehicle Immobilization System) has kicked in and the car is bricked. More than likely when whoever swapped the BCM they did not sync it correctly. For these cars, not only do the key fobs have to be synced to the "new" BCM, but the key slot ALSO must be synced. There is a transponder chip in the slot and that code has to be set in the BCM as well as the iKey ID's. Once everything is properly synced the car should start.
Download section SEC (SEcurity Control System) of the factory manual from here. Page 17 explains it all.
In a nutshell, find someone who can fully and properly register all the ID codes- preferably one who has Nissan's CONSULT3 tool.

Thanks for the input. The shope didnt give me the actual codes so im unsure exactly what codes came up. Going off of word of mouth. I had alot of struggles with communication with this shop. I will be sure to pass the information to the new shop. Thank you!

Update
New mechanic found clutch had been by passed leading to a blown fuse replaced fuse and got power again. Checked BCM and found ground wire was disconnected. Replaced the ground wire. Car now goes into ACC mode and keys are working. Re flashed vehicle with UPREV to disable IVIS (NATS) and car will still not start. any ideas on next steps?
