Hey all, I recently got a G35x and I'm having an issue regarding the proximity key.

The proximity buttons (doors, trunk) do not work. If I press them, nothing happens. I can only lock/unlock/open the trunk via the key fob.

When I try to start the car, it does not start unless I have the key inserted in the slot on the bottom left slot on the dashboard, near the VSC controls and buttons.

I do not get any key battery warnings on the dashboard, but I have replaced the key battery and nothing changed.

Has anyone encountered/fixed this? Which fuses would be responsible for handling this?

Thanks all

 

You need to run NATS diagnostics using a 'reputable' scan tool or Consult 3+. Most likely you have to reprogram the key fob(s) so the BCM could 'refresh' its worthless security system.
Do you have 1 or 2 key fobs? If one, then you can't test if the key fob itself has a bad transmitter or the BCM has a security fault.
Here, get your Factory Service Manual as online speculations won't fix your issue.
