Unlocking Master Lock: How to Crack a 4-Digit Combination

Tools Needed:

  • A tension wrench
  • A picking tool (a paperclip or bobby pin will suffice)

Step-by-Step Instructions:

  1. Apply slight tension: Insert the wrench into the bottom of the lock’s keyway (the small opening where you usually insert the key). Turn it slightly in one direction.

    • Note: The purpose of applying tension is to create binding between the pins inside. You don’t need too much pressure – just enough so that you can feel resistance.
  2. Find first binding digit: Insert your picking tool into the top of keyway.

    • Note: The idea here is to find out which number has more resistance than others.
  3. Test digits for Binding Order:

    • Starting with “0”, gently press each dial inward towards shackle until one clicks.

    • Repeat step above for all potential numbers

    • Note: If several numbers click incrementally between them, they are probably correct order.

  4. Cracking sequence: Once correct order determined Pull shackle up while turning back-and-forth applying pressure toward each individual dial’s next possible number untill last dial clicks

Pro tip: It might take some time and practice before successfully cracking open a lock using this method!
