All of a sudden today, the lock, unlock and trunk release buttons stopped working on the remote CA key fob. I did not get a low battery warning from the dash board.
However comfort access door lock and unlock as well as trunk unlock with keyless touch still works okay. Starting car with comfort access all okay too.
So what gives ? Not possible that all three buttons are simultaneously broken at the same time. I didn't drop this key or throw it on the washer.
