Equinox EV would not detect key fob, had to disconnect and reconnect 12V battery
Car would not detect key fob and would not drive. Key fob definitely had battery. Door handles would not automatically swing open when approaching. Pressing the lock/unlock buttons on the key fob worked (door handles would swing out) but dashboard still said key fob not detected and car would not drive. Placing key fob directing on the RFID reader in the cup holder did not work either.
Disconnecting the 12V battery in the hood, waiting 1 minute, and reconnecting the 12V battery fixed things. Probably a software bug that got reset after restarting the car when the 12V battery was disconnected and reconnected. Hope this helps someone else with the same problem!
