What I'd say instead of "keyhole, please"

Saying a style name at a consult feels efficient, but keyhole means different things to different people. For most, it's the little opening at the centre of the mouth when the face is relaxed.

Whether that opening shows up has a lot to do with how your lips rest today. Worth asking about before you talk volume.

I read this description of the keyhole lip look first, so I could say what I liked in plain words.
