The lyrics to the title track are commonly accepted[by whom?] as sexual innuendo. However, Hagar has presented a story with a much more philosophical bent: "It's got to do with deep sea diving, when you look for a buried treasure. The ultimate treasure would be a sunken treasure with three locks on it, because that means it was the most valuable stuff that the queen had on that ship. And you need three different guys with keys to open it, that way no one could steal it. So a 'Three Lock Box' to me is within yourself. If you unlock the treasure of your physical, and your mental and your spiritual potential - those three in balance - you are a real human being and almost godly."
