How do you get the door lock to unlock?
 

I am the new owner of a 1930 closed cab pick up. It was restored in 2010, and sat for awhile after that. In my attempt to make the passenger side door lock work, I got the key to lock and now can't get it to unlock! Put lock-eze in there and am fiddling with the key any suggestions?

Work the key back and forth in the lock to get the tumblers loosened up. May roll down the window to access the back of the door latch. get some penetrant on the back of the latch, and the back of the handle.
