When you say "key" do you mean a swipe card? Or a key? And if you say swipe card, did you get a whole one or a ripped one?
If you got a ripped card, there were some instructions there giving you a hint about what you might need to do with it. If you get another one, you'll see the instructions again.
It's not a bug. It may be written badly, though. I'll look into it.
As for the pop-ups, I don't think so. They'd get annoying. My goal is that the text should give this stuff away. If it trips a lot of people up, I'll try to improve it.
