So the driver door lock on my Sedona is jammed. The van still locks/unlocks perfect from the fob and from inside the vehicle. But the actual lock from the outside will not turn. the key slides in nicely, and I puffed some graphite powder inside, but to no avail. Ive also tried tapping on the face of the lock with a tack hammer. any suggestions? Maybe blast some brake parts cleaner in there? The van still has the bumper to bumper warranty, but I'd assume that the lock is a wear item and not covered.
