A padlock having both a combination mechanism and a key mechanism that can be opened by either mechanism, having an indicator that moves to change the appearance of the padlock from a first state to a second state if the padlock is opened by the key mechanism, wherein the indicator can move to restore said appearance from the second state to the first state only after the padlock is opened by the combination mechanism. 11. A padlock having both a combination mechanism and a key mechanism that can be unlocked by either mechanism, having a color indicator that moves to alter a color displayed by a region of the padlock from a first color state to a second color state in response to the padlock being unlocked by the key mechanism. 12. The padlock of claim 11 wherein the color indicator can be moved to alter the color displayed by the region of the padlock from the second color state to the first color state only after the padlock has been unlocked by the combination mechanism. 13. A padlock having a combination mechanism and a key mechanism that each can be used independently of the other to open the padlock, and having an indicator that moves, in response to the padlock being opened by the key mechanism, from a first position causing the padlock to display a first appearance state to a second position causing the padlock to display a second appearance state which differs from the first appearance state, wherein the indicator can be moved from the second position to the first position to enabling the padlock to display the first appearance state only after the padlock has been opened by using the combination mechanism. 14. A padlock comprising: a) a combination mechanism that can be used to unlock the padlock by setting a combination; b) a key mechanism that can be used to unlock the padlock with a key; c) an indicator movable from a first position enabling the padlock to exhibit a first appearance state to a second position enabling the padlock to exhibit a second appearance state in response to the padlock being unlocked with the key; and, d) a reset mechanism configured to move the indicator from the second position to the first position at a time after the padlock has been unlocked as the result of setting the combination to thereby restore the padlock to exhibiting the first appearance state. 15. A padlock having a combination mechanism and a key mechanism that are usable independently to open the padlock, and having an indicator which moves from a normal position in response to opening of the padlock by use of the key mechanism to provide the padlock with a change of appearance indicating that the padlock has been opened by use of the key mechanism, wherein the indicator can only be reset to the normal position when the padlock is opened by use of the combination mechanism. 16. A combination operated lock that also can be opened by a key wherein the lock includes an indicator element that moves from a first position to a second position in response to opening of the lock by said key to alter the appearance of the lock to indicate that the lock has been opened by said key, and wherein the indicator element can only be reset to the first position at a time after the lock has been opened by use of a predetermined combination. 17.
