Angelina if i don't have anything else with me, why shouldn't i try?
Because you can break the engine! ๐
Personally,I don't tend to try something(like putting water in a fuel tank),if I know or I'm pretty sure it wouldn't work.
Raziel The best way I could think of to have control of the key is to have a glass/ceramic piggy bank with a lock on it, so it can be opened safely with the lock that only Katie knows the combination to. In emergencies, the piggy bank would be thrown to the ground and smashed opened, never to be used again, and that'll be proof enough if the key was taken by force.
Not a bad idea.

Good question.
