the passenger door does not unlock completely with the key
the door lock seems to pop up only halfway, so we have to open door from inside. these
are not power locks.
Try spraying some WD-40 into the cylinder. If no luck, you will have to tear the door panel off and lube the internal parts.
Move over to the passenger side and use the key. Note the travel of the turn, probably a quarter to a third of a revolution before it unlocks. Is the travel the same on the drivers side? If not, try Reelin68 suggestion. If the travel is the same you will have to remove the inside panel and check for problems.
