I’ve got a 2009 g37x I’m having a problem of my amber fob light and security light being on but outside of the car if I hold the lock button it doesn’t lock or unlock the doors but my green turn signal lights pop up on the dash, but when I put the key in the slot it beeps but press acc or even on none of the computers come on except the amber light and security light?

 

It's possible you've triggered the Vehicle Immobilizer System. From the Owner's manual:

The security indicator light is located on the meter panel. It indicates the status of the INFINITI Vehicle Immobilizer System.
The light blinks after the ignition switch was in the LOCK position. This function indicates the security systems equipped on the vehicle are operational.
If the INFINITI Vehicle Immobilizer System is malfunctioning, this light will remain on while the ignition switch is in the ON position.
If the light still remains on and/or the engine will not start, see an INFINITI retailer for INFINITI Vehicle Immobilizer System service as soon as possible. Please bring all Intelligent Keys that you have when visiting an INFINITI retailer for service.

I am not sure how to reset that system but maybe you can search for some advice on the subject? Hope that helps.
