A fixture and method allows a mechanic to add a key to a crankshaft without removal of the crankshaft from the engine. The keying fixture has a main body having an axial internal bore for mounting over a crankshaft. The main body includes a sealing portion for forming a seal between the engine and the keying fixture to prevent debris from the keying operation from entering the engine. The main body also includes a bushing mounting portion for mounting drilling/reaming bushings of a desired size in the keying fixture to provide for precise radial alignment of a correspondingly sized drill bit or reamer used for creating a radial key bore.
