You can't open the door if you don't have the key

You can't open the door if the battery is dead (or, presumably, the battery has removed by a would-be car thief).

I'm not sure why one of these is a "failure of the car" but not the other.

If the Tesla cars defaulted to "doors open" when the battery was dead/removed, people would be complaining about that.

In both cases, the end outcome is exactly the same: the window gets bashed out by the fire department.
