And there's the weakness. An emergency key that you can use means there's an emergency keyway that can be picked.
And thank goodness, too. I spoke to a locksmith a while back and he told me about some fancy import sports car with no emergency keyway and there was a child locked in, and of course the key was in the vehicle.
He did get the door open, IIRC there was a button to press to unlock, but not where his long-reach tool could easily get to. He said a cop had to watch from the other side and guide him to the button. He said it took around an hour to open.
Moving towards? I don’t think you can buy a car that has a physical key anymore can you (except for the emergency key you can pry out.)
