Proper crank case pulley install

I was getting read to reinstall the crank case pulley and see that there are two flats on each side of the insert for the pulley but it looks like there is a slot for the keyway on the sprocket. Do I need to ensure the keyway engages the pulley or just align the flats? Thank you.

The keyway needs to align correctly to get the pulley fully engaged. The two flats are for the oil pump gear. Have look at this youtube videos, it shows the pump internals and the two flats on the gear are evident. Hope this helps.
