Abstract
Locks for luggage, travelcases, briefcases and the like that can be operated by setting a combination or by using a key include an indicator to provide a signal in response to use of the key. The locks retain relatively movable components in latched engagement when locked, and permit relative movement of the components when unlocked. In some embodiments, the indicator provides a visual signal if an associated travelcase has been opened for inspection by unlocking the associated lock using a key; and, in some embodiments, the indicator can be reset upon entry of a proper combination.
