I have the exact same problem, did you manage to find the root cause/solution ? Thank you

Attention to detail

I wanted to share my self-inflicted experience on this issue in case it's helpful to anyone.

I removed, disassembled, cleaned, dielectric lubed, and reinstalled the clutch switches due to an intermittent starting issue where the car would cycle through acc, on, off as if you're not pushing the clutch in.

Maybe a month later, I notice the cruise light will come on but it will never engage and drive the car (rarely use cruise). I believe the intelligent key light became illuminated around this time.

I can't remember the sequence of events, but over the next few weeks, the fob functionality seemed to deteriorate. At some point the door locks didn't operate remotely. I swapped the fob battery and I recall that helping. Disconnected the car battery to reset the key light and that worked for a short while. At some point I got my back up fob involved which had been sitting for 4 years. Over this past weekend I started having to insert the fob into it's fobhole to get the car to start.

Started poking around here and recalled the switch work I did. I either left the upper switch off or didn't fully engage it's retainer clip. Track day may have encouraged it out. Plugging the switch back in resolved the cruise and key fob issue. The unused fob doesn't work remotely, but the main one does.

To add a little information. The only things that have changed in the past day were my windshield was tinted, and I removed the “console” around the shift knob only. I unplugged the main cable and double checked that I plugged it back in. This appears to be just for the hazards and sport mode.

Just seems odd both keys quit working the same day.

I had front Windshield tinted on my 2009 370Z today and this happened to me as well. When I parked the car, to told me no key detected when it was in my lap and still doesn’t work on the doors. On top on that my S-Mode error popped up and after replacing the key fob battery and taking off the + battery terminal and putting back on.. nothing. I am thinking there was water damage done.
