A combination and padlock includes a housing including a front window, a dial assembly, a cylinder having a keyhole, a rotatable member secured to cylinder and having a spiral groove, a sleeve including fingers moveably retained in the groove, an indicator slidably mounted on the sleeve and including a first state surface having a color aligned with the window in a locked position, and a second state surface having a different color, and a shackle. Inserting a key into the keyhole to clockwise turn the cylinder and the rotatable member will move the sleeve downward by moving the fingers along the groove in one direction, and unlock the lock with the second state surface moved to align with the window for visually informing that the lock has been opened by the key. Alternatively, counterclockwise turning the inserted key will lock the lock and reset the indicator.
