As yet, neither Belarc Adviser nor the Magical Jelly Bean Keyfinder appear to be able to retrieve Office 2013 keys, so you may be out of luck there.
However, you could contact the Microsoft Customer Service for help finding your product key. To contact the Microsoft Customer Service Center in the US or UK, call one of the following numbers:
North America: 1-800-MICROSOFT (1-800-642-7676)
UK: 0844 800 2400
Even without doing that, I doubt it really matters which product key you use on a given PC, provided you have licenses covering all installations. The only time it might be an issue is if you use up all the licensed installations a particular key allows, in which case switch to one of the others.
