Bill and other interested parties, If I'm reading what you wrote correctly, you should say either "Through the 1970 model year..." or "Up until 1971..." since my 70 LeBaron has the anti-lockout feature. I find having to lock the door with the key from outside every time quite annoying and would like to undo this little feature. Pete in PA Bill Watsonsrote: ...Up until 1970, Chrysler Corporation cars could not be locked from the outside by engaging the lock and then closing the door. The lock had to be engaged from the inside when the front door was closed or from the outside with the key when the front door was closed. Rear doors could be locked by pressing the button or flicking the lever and closing the door.
