What have we here?
“We know that the Moon is “tidally locked” to Earth, always showing the same face since its rotation matches our own. But it’s not perfect. Thanks to a something called lunar libration, the Moon sort of oscillates in its elliptical orbit, and we are able to see slightly more than half its face throughout the year.” via Joe Hanson and Philip Plait .

If an Asteroid of sufficient mass became trapped at say L2 or L1, would the “tidal lock” be broken and the Moon begin to spin again? It seems its a matter of the CoG or some part of the system.
