A self-scrambling combination includes a frame that supports at least two tumbler rings and an activating slide. The tumbler rings are marked with characters used for a combination for the lock. The lock is openable only when the tumbler rings are located in an open position related to the combination. The activating slide moves a locking bar between a locked position and an unlocked position. A scrambling mechanism is attached to the activating slide and rotates the tumbler rings from the open position to another position upon movement of the activating slide to move the locking bar from the unlocked position to the locked position. The frame can be used as the door of a lockbox and an attached key lock controls the setting of the combination for the lock. The self-scrambling combination lock can be used for a briefcase or valise lock with an additional spring closing the lock.
