How to Open a Master Lock Without the Combination

The only way to open a Master Lock without knowing the combination is to use some form of lock picking tool, such as a set of lock pick tools, or a tension wrench. You will need to insert the tension wrench into one side of the keyhole and apply light pressure while simultaneously manipulating each pin with your picks. Once all pins are in place, you can then rotate the plug until it unlocks.

Keep in mind that this process may take several tries before successfully unlocking your lock. Additionally, if you do not have any experience using these tools it can be difficult and time-consuming so professional locksmiths are recommended if possible.

  • Locate a master lock that is open or has been opened previously
  • This can help you to get an idea of how the combination works and what it looks like when it’s open
  • Examine the lock carefully, noting any numbers or symbols on the outside of the shackle (or arm)
  • A Master Lock will typically have three digits printed at one end of the shackle and four symbols at the other end which represent each number in its combination code
  • Keeping these numbers/symbols in mind, locate a pick set or paperclip-like object that can be used to manipulate tension against the pins inside of the lock cylinder while turning the dials with your fingers until all pins are released and you hear a clicking sound indicating that it is unlocked successfully without using its original combination code! 4
  • Turn all three dials on your Master Lock back to their default position (usually all zeros) before trying this again so as not to damage any internal parts by over-adjusting them too much during unlocking attempts!

How Do I Open My Master Lock If I Forgot the Combination?

Opening a Master Lock if you’ve forgotten the combination can be tricky, but it is possible. The first step is to identify what type of lock you have; Master Lock offers several different types of locks which require various methods for resetting. If your lock has a serial number on it, three letters followed by seven digits, then there are two options available to you – contact the customer service team at Master Lock and provide them with the serial number so they can tell you the existing combination or cut off the shackle and purchase replacement parts from them directly.

If however your lock does not have a serial number then unfortunately this means that it cannot be opened without cutting into it as no records exist of its original combination.

How to Crack a Master Lock Combination Lock?

Cracking a Master Lock combination lock is not as difficult as you may think. With the right knowledge and some patience, anyone can learn how to do it. The first step in cracking a master lock is to determine the size of the padlock you are trying to open.

Once you have determined this, insert the shackle into its notch and turn it so that it rests in its unlocked position. Now use your tools (such as a flathead screwdriver) to release each wheel from its catch one at a time until all of them move freely around their dials.

Then rotate each wheel clockwise or counterclockwise until they align with what appears on the back side of the padlock body – usually five digits such as 0-0-0-1-2 or 7-4-1-3-8 depending on how many wheels there are and how large their numerical range is.
