I've only noticed this feature on Fords. My SAAB requires the occupant to pull up on the lock knob on the windowsill, and my Saturn requires one to turn the lock knob on the inside door handle to the unlocked position. While both require additional action besides just pulling the handle, neither relies on the car's electrical system to open or unlock the doors (and indeed, neither car has any electrical locking component in any of the doors).
