  1. Use the Blacklight to see the fingerprints on the right numbers. These are the only ones you’ll need to unlock the door with.
  2. Even if a number has a fingerprint on it, it might be unused and marked with a red X. Remember to not use that number again in your unlocking attempts.
  3. If a number is marked green, never ever change it in your current attempt. If it’s yellow, however, just change its position the next time you dial.
  4. Some numbers might be used twice. You may find a clue for it with overlapped fingerprints on a certain number key.
