Unlocking the Code: How to Hack a 3 Digit Combination Lock

Are you tired of fumbling around with your combination lock, trying every possible combination in hopes of finding the right one? Well, fear not! With these tips and tricks, you’ll be able to crack that pesky three-digit code in no time.

Unlocking the Code: How to Hack a 3 Digit Combination Lock


Combination locks are commonly used for securing our valuable belongings. Whether it’s on a locker at school or gym, or on a safe at home, knowing how to crack one can come in handy. In this article, we’ll show you how to hack into a 3 digit combination lock using different methods suitable for beginners and advanced users alike.

Method 1: Brute Force Attack

The most straightforward method is brute force attack – trying all possible combinations until you get it right. This requires patience as there are 1000 different combinations (000-999) but requires no special tools or knowledge other than single-minded determination.

  1. Begin by turning the dial clockwise two full turns.
  2. Then turn the dial counterclockwise directly past your first number and stop precisely on your second number.
  3. Finally turn the dial clockwise again until it stops – this should make an audible “click” sound if done properly which means that now correct number is set.
  4. Repeat these steps again using each possible third digit until successfully opening the lock!

While tedious, brute force attack is still an effective way to open a combination lock without any specialized tools.

Method 2: Using Shim Technique

For those who want something faster than brute force yet don’t mind purchasing some additional supplies (or have them already), using shim technique may be ideal:

  1. Insert a thin piece of metal called “shim” between shackle mechanism and locking mechanism from outside through left side.
    • You can create your own shim by cutting up aluminum soda cans or use readily available shims online.
  2. Push the shim towards the other side of locking mechanism (right side).
  3. While holding it in place, turn the dial with your other hand and eventually the lock should open allowing shackle to be removed.

This method is faster than brute force attack and does not require any skill but may damage your lock making it unusable afterwards.

Method 3: Using Locksmith’s Tools

For high-security locks or those that aren’t responding to shim technique, you might need specialized tools such as a bypass tool or a jiggle key from a locksmith. Although these tools are generally expensive compared to others, they can be effective for opening many types of combination locks.

If you decide on this method:

  1. Insert tool into lock while gently jiggling it until all possible pins/movements have been tried.
  2. Apply some torque with turner tool and carefully wiggle/pull/turn until well-positioned pin(s) fall into place.
  3. Turn key/shackle at once when resistance decreases indicating proper alignment which should allow for easily removing shackle from lock.


In conclusion, cracking open a 3 digit combination lock can seem daunting initially but armed with knowledge about different ways to approach them plus some patience there’s nothing stopping us from opening our secured valuables! Even though these methods may work against most common combination locks without issue special care should always be taken during use so no one gets hurt nor damages property unnecessarily!

By following these tips and tricks, you’ll be able to hack into any three-digit combination lock with ease – whether it’s yours or someone else’s!
