An Oily, Dirty Little Lock

This LaGard (model 2270) key operated safe lock was removed from a fast food restaurant safe after it failed to allow the key to enter the keyway. There were a few surprises left behind by the store manager that might have made this safe opening worse than it actually was. Oil, dirt, cooking flour, improper maintenance, and an overzealous restaurant manager did not make for a good combination (pun intended) for this safe lock.
