That's old stuff. My 64 Dodge wouldn't lock the driver's door with anything but a key. Of course, people tried pushing the button in, then locking the door, but when you shut it- the lock popped up. The only way to lock the keys in that car was to unlock the rear door, lock the driver's door from inside with the door shut, then lock the back door and shut it.

Why Ford, or any other manufacturer strayed from thinking like this is beyond me. Fords are certainly not the only vehicle on the market that can lock the keys in the car. It makes me wonder if the older engineers were smarter than the new ones because they could design a lock system like this- mechanically.
