So my 2015 Mazda 3 has done this thing 4 times in 2 Days. First was Friday morning and Saturday morning. Twice since this morning. Go to unlock the car and nothing happens. Have to use the physical key. Both morning times the car started just fine but this afternoon and evening it wouldn’t start. I exited the car. Shut the door. And the lock beep did it’s thing. Got in the car and everything worked fine. Got a new car battery. Possibly the fob
