A note of Caution.

Once unlocked, most combination locks can easily be reset if we are not careful.

Please be aware that when in the unlocked position, the bottom metal loop on the lock can be pushed in.  If this happens and the dials are then turned inadvertently, the lock will be reset to a new Combination.

In this event, we can probably find the new combination by trial and a little patience. Start with combinations nearest to the original.
