The only one I can think of that you haven't tried is sea foam deep creep. Have heard it's really good stuff but never used it myself.

Did you try heat ?
Maybe a heatgun in an attempt to expand the internal parts and melt the salt deposits inside , may take a few attempts . Once cool enough to touch then try water & vinegar.

Might try graphite.
It's as if the tumblers are welded to one another. If I could just get the key in, maybe I'd keep going with liquids and heat. I can only put so much pressure on the key before it is worthless. I did try a few heating cycles; first with heat gun, then with a propane torch. No change, other than the liquid (probably PB) inside started on fire. The salt is definitely all gone now. Unfortunately, I think the damage is done. I'll mess with it again in the morning. If no change, I'm done playing around; it's getting cut off one way or another. Thanks again for the suggestions.
