2014 QX60 Hybrid - Wouldn't start with push start. Wouldn't start with with key on Start button. Pushing nothing, pushing lock button, or unlock button. Waited for chime and that would re-pair and allow to unlock and lock when right near car and I could lock and unlock car with physical key. if fob was not paired, it would allow lock with physical key but not unlock with physical key. Fresh 2032 batteries with full 3.3V in 2 fobs. When I attempted to start car after re-pairing it would get to 2nd full lights on instrument panel but then nothing else. Would get "brake and start" indicator and then Key ID Incorrect. Replaced car battery, everything worked like a champ. As I read somewhere, low car battery will cause all kinds of crazy shizz. I put this here for the other folks that can't make any sense of seemingly keyfob issues.
