I have found a third key now, so I take it the point is now moot. This is a rhetorical question only if the answer is yes. That's because, if there are 6 keys rather than just 3, I don't want you to tell me, as I'll certainly find that out if/when I gather yet another key.
So what I'm sayin' is, don't tell me if there _are_ more than three keys. Boy, now I'm confusing myself. hahahahaha.
