What's going to happen when someone discovers on a flight that a box of in-flight meals, napkins, or something wasn't sliced open before takeoff?

I have no problem opening boxes with my car keys.

Depends on the box and the keys. On the other hand, you'd better keep your mouth shut or you'll be required to put your keys in your checked baggage.

nb: Keys make much better weapons than a lot of the things which were banned. Go figure.
