Help! I lost the one and only key to my vintage Ramcharger. The ignition and door lock is the same key. Locksmith said if I took the door lock out of the door he can fashion me another key replacement. However, after removing the interior door panel, I was faced with a piece of sheet metal preventing me access to the window actuator and the door lock. The only access I have is through cut-out holes here in there, barely enough room for my hand let alone tools. Can anyone tell me how to remove the door lock from the door?
