Do not apply localised heat to your crankshaft.
The technique I generally employ is to slowly 'worry' it out with taps from different directions. Once you get a little movement going more will slowly follow. Apply leverage or a drift under any overhang if there still is one. Try striking from above (with a drift) to rock it in its groove. Persevere. If truly stuck you may have to resort to machine tools e.g. drill it through, and it still might put up a fight. But it's one of those cases where you should exhaust the least aggressive methods before you up the ante.
