Never locked myself inside (and would never admit it if I did) but the second night after I brought my ’50 P/U home I did not want to have it towed away in the night again (long story involving the California DMV) so I made sure it was secure by locking both doors before closing them (see where this is going?) by pulling down the inside handles and closing the doors. Quite shocked the next morning when my key had no effect towards entry into my new prize. I never knew you should not lock them that way. We had a ’54 Chevy one-ton farm truck for years, but never locked the doors. I ended up pulling the back window (and broke it!) to get in. Lesson learned.
