Insert the lock box key into the key hole (if there is one). Some Grecian lock boxes 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.
Turn the combination dial two full rotations counterclockwise and bring it to a stop on the first number of the combination.
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.
Turn the dial counterclockwise to the final number in the combination.
Turn the key (or dial, depending on the lock box) slightly to the right to open the lock box.
