Before resetting the lock, you need to know how to open it using the current code.

  1. Clear the Dials: Rotate the dials slightly past your numbers to ensure they are aligned. The SD 103 has a "false gate" feature; if the dials are not perfectly centered, the lock will not open.
  2. Dial the Combination: Turn each dial to the correct number. Align the number precisely with the indicator line (usually a small arrow or line etched into the metal body).
  3. Apply Tension: Pull firmly on the shackle (the U-shaped metal loop). If the combination is correct, the shackle will release.

Tip: If the lock does not open, do not force the shackle. Return all dials to zero and try again slowly.
