2014 Lexus RX 350 - Dead something

My car would not lock with key fob and wouldn’t start, seemed like no electric power at all. After 10 minutes it came alive and started. I turned it off and locked it and then couldn’t unlock it. Had to have AAA pop the lock then it worked again. Dealer found nothing on scan, battery good 10 months old, key fob battery is 3 months old too

If the vehicle won’t respond to the Smart Key, remove the key blade from the remote and use it to unlock the vehicle.
