Dunno if the SPD one is actually same fit.
But you need the Look tool for KeO Classics and Sprints, Carbons you simply need a ring spanner for.
Remove pedal from bike and put into vice/workmate, then turn tool appropriate way - for no reason I can imagine, the Look tool has direction arrows saying which way is tighten and loosen on the left and right pedals, but it's on the the face-down side when you're using it...
I've not actually had the bearings out of the pedal but have removed the axle, regreased and put it back in - major improvement !
