Woodruff key is probably good since it does not drive the pulley only the timing belt sprocket fits over the key(unlike 12V 3.0). You'll need a new sprocket because the weak roll pin that locates the pully will be sheared off. The only thing that keeps the pully from spining on the end of the crank is the pressure from the bolt and washer. Recommend a new pulley too so you have fresh mating surfaces.When it spins like that it mars the surface.
