Keyway kicking my butt

I recently purchased a bunch of locks with similar keyways to this, to practice on, and they are absolutely kicking my butt. For reference, I've picked up to orange belt, but only a couple of them so im still pretty new.

The angle keeps muddying my feedback and I can't figure out how to maneuver around it. I'm using the CI Reaper set right now. Do I need thinner profile picks?
