As early as 1875, American post offices started using Grecian front combination lockboxes. As modern banks do not use these types of lockboxes, nearly all of them have been removed and sold to private owners to be used as decorative safes. The locking mechanism is combination in form, so to unlock one of these lockboxes you need only know how to unlock a standard combination lock.

Skill level:


  1. 1

    Insert the lockbox key into the key hole (if there is one). Some Grecian lockboxes have a key that is used as a knob to open the box after it is unlocked whereas others use the combination dial itself as the knob. If there is no key hole, ignore this step and move on to Step 2.

  2. 2

    Turn the combination dial two full rotations counterclockwise and bring it to a stop on the first number of the combination.

  3. 3

    Turn the dial clockwise one full rotation past the first number in the combination and bring it to a stop on the second number in the combination.

  4. 4

    Turn the dial counterclockwise to the final number in the combination.

  5. 5

    Turn the key (or dial, depending on the lockbox) slightly to the right to open the lockbox.
