# Crack the Code: How to Open a 4-Digit Combination Lock

## Introduction

Combination locks are commonly used in various settings, from school lockers to gym lockers, bike locks, and even luggage. They provide a convenient and secure way to safeguard your belongings without the need for keys. However, when you forget or misplace the combination, opening a 4-digit combination lock can be frustrating and time-consuming. In this article, we will go over how to open a 4-digit combination lock using simple techniques.

## Understanding Combination Locks

Before diving into the methods of opening a 4-digit combination lock without knowing the code, it’s important first to understand how these types of locks work.

• Combination locks have an internal mechanism that aligns with specific numbers on each dial.
• The sequence is usually three or four digits long.
• Each wheel has ten notches that correspond with each number on its outer ring.

Additionally, most common models contain at least one weakness or vulnerability that makes it possible for people skilled in decoding them able to bypass them.

## Method 1: Trial-and-Error Technique

The trial-and-error technique involves testing all possible combinations until you find the correct one.

1. Start by turning the dial clockwise two times until you reach zero.
2. Then continue turning clockwise while stopping at each number within your sequence once before reaching it again.
3. When you feel resistance while pushing down on any particular digit (i.e., when one of those numbers clicks), note which one it was and move onto next digit after resetting back to zero (clockwise twice).
4.Now take note of what order they were clicked as well as their position relative
4. For example if Clicked Position #1 was “5” , Position #2 was “14” ,Position #3 was “23”,Position #4“34”
5. You will now have 4 numbers which you can plug into many different permutation machines on the web to brute force any possible combinations – this will take less than a few minutes
6. Continue with every remaining digit and record those that cause resistance until all four digits have been found.

## Method 2: Shim Technique

The shim technique is an alternative method to opening a 4-digit combination lock, but it requires more skill and finesse.

1. Purchase or create a thin piece of metal (make it similar in size to the width of a guitar pick) A soda tab works fine as well.
2. Insert the shim between the lock’s shackle and body while turning the dial clockwise as far as you possibly can.
3. Once you feel significant resistance, apply pressure upward or downward on both sides of this exposed gap, allowing your homemade tool enough space inside for rotation
4. Slowly progress through each number within your sequence once again making note of what order they were clicked in

Note: This method only works if there are no security pins installed.

## Method 3: Decoding Technique

There are decoding machines available that can quickly decode most combination locks regardless of make or model.

1.Local locksmiths may also offer this service – even some “key copy” shops like Home Depot do
2.Professional Locksmith equipment such Sledge Hammers larger code-breaking tools can break these locks

This method might be expensive if you don’t perform often so we recommend using options mentioned above first!
