Heat normally, I guess you could try the oven or maybe a soldering gun for more direct heat (not sure what that will do to the finish, nothing good I'd guess) . Loctite do make a solvent I think.
I broke the lock on my speedplays by putting a bit in the screw and applying a blow torch to that. Maybe you could scale it up, but you'd loose heat transference with the increased scale
