I left it this morning for 1.5 hours after Power Off from touchscreen and without phone access, and still NFC reader is not getting reset.
I wish there was a way to do a deep reset similar to a software update, because that fixed the issue last time.
Changing wheels (and changing them back) in the service menu is supposed to do a deeper reset. Like change to 20” and back, depending on what you have currently of course.

I also do not believe the power off does anything. The screen pops back on way to fast in my car to be coming back from a full power off state

I tried changing the wheels, and the MCU was rebooted, but still NFC reader is still not connecting to my phone. The reboot from changing the wheel configuration seems similar reboot as when pushing the two scroll buttons on the wheel.

Tesla FAQ says you can power off the car in two ways, either by exiting and closing the door, or through touchscreen. The car goes to sleep after a few minutes to conserve power, and then there would be a delay to wake up once it does.

How do I turn my car on and off?

You can start your Tesla by pressing on the brake pedal and putting into gear. In Model 3, if you are not using your phone key, place your key card on the console and put the car into gear.

You can turn off your Tesla by putting the car in park, exiting the car and closing the door behind you, or on your touchscreen through Controls > Safety & Security > Power Off.

Interesting. Implies that leaving the car and power off are the same. None of which would ever turn off the rfid or could never get back in.

You can always disconnect the battery and the connector under the rear seat.
