Explanation: An attempt to render the meaning of the term into a few words which tie it to your context, and focus attention on the fact that it is an actual physical key which is being spoken about. "Key statement" would usually be taken to mean simply a crucial statement or a statement of principle, and not something which relates to a physical key with which one opens a physical door. I am hoping that this suggestion will do the trick for you.
