How to Open a 4-Digit Master Lock: Step-by-Step Guide

Understanding Your Lock

Before attempting to open your lock, there are some things that you should understand about how it works:

  1. Your lock has four dials with ten numbers on each dial (from 0 to 9), totaling up to more than one million possible combinations.
  2. Only one specific combination unlocks your lock.
  3. Each time the correct combination is entered, the shackle will release and allow the padlock to be opened.

Steps for Opening a 4-Digit Master Lock

Follow these steps carefully, and remember that safety comes first – use protective gloves or glasses if necessary:

Step #1: Find an Appropriate Place

Choose an area with good lighting and minimal distractions so that you can focus on unlocking your padlock easily without any interruptions.

Step #2: Turn the Dials Randomly

Turn all four dials randomly until they no longer turn; this helps ensure that none of them are caught in between two numbers which could result in an incorrect combination.

Step #3: Starting from Zero

Begin by aligning the first dial (left-most) with zero (0).

Step #4: Test Each Number Combination

Starting from left-to-right test each potential number for each dial – start testing at “0000” then attempt “0001”, next try “0002,” continuing till reaching “9999” while leaving plenty of pauses between each adjustment made during testing.

Keep turning each dial incrementally clockwise after each attempt. Listen for the clicking sound when you hit the correct number, which is an indication that your dial is correctly set.

Step #5: Repeat Step #4

Repeat step 4 until all of the dials are in their correct and corresponding positions.

Check to make sure each dial has been dialed-in with its proper respective position; if any one or more are out-of-order, start over from step three again to ensure success as usually when one dial is off by a single number it means all four will also be incorrect.

Once every dial is properly aligned at its specific combination’s numbers sequence, turn clockwise and then pull down on your lock’s shackle. If successful, your padlock should come undone!


Opening a 4-digit Master Lock can be easy if you follow these steps carefully. It’s important to take safety precautions and not rush through this process just because you’re feeling impatient. In case of failed attempts, repeated them again from scratch,and always keep it mind that practice makes perfect.
