Last resort- - - -carefully drill the pin out. It's a simple common hardware item that can be replaced, so don't waste a lot of time struggling with it. Start with a small drill bit, maybe 1/8", and drill the hole out in steps until it's close to the full diameter. Then use penetrating oil and/or heat to remove the remaining shell. Use a drill press if possible, instead of a hand drill motor.
