First of all.. isn't the correct order of his name "Keegan Michael Key"?
Second... there's really
not a lot of material out there.. and he has changed appearance so much over the years (not to mention all the costumes and disguises he dons for his characters) that I wasn't even sure that all the images I found were really of him... So with that caveat, I'm fairly hopeful that the first one is an old professional shot of him, but
I'm not absolutely certain:
