"My, and it locks and unlocks." Heh, of course it's a key (one with a rather terrible, gaudy design, Sebastian privately thinks, being the nice, non-judgemental person he is). Apparently the fact that it is indeed a key is a funny enough observation that he needs to chuckle softly, a hand politely over his mouth.
(You know how everything is hilarious when you haven't slept for thirty hours and it's 4 AM? Yeah, that.)
