The Trick

The trick involves finding out which numbers on the dial correspond to the shackle’s release mechanism within the lock body.

Step 1: Pull Up on Shackle

Firstly place tension on both sides of the shackle (the U-shaped part that goes through whatever you’re locking up). Then gently pull up on it as if trying to open it and hold it in place.

Step 2: Rotate Dial Anti-Clockwise Until It Stops at First Number

Next, turn the dial anti-clockwise until you feel resistance from inside the mechanism. Once this happens stop turning immediately – this is typically when you feel/hear a “click”. This number will be your first digit.

Step 3: Rotate Dial Clockwise Until It Stops at Second Number

Now rotate clock-wise past zero once then turn clockwise again for about two full rotations before stopping when hitting another number – this indicate second digit.

Step 4: Repeat Process for Third Number

Continue rotating anti-clockwise until encountering resistance then check “click” sound; take note of third number in sequence.

Rotate around clockwise again past zero before stopping at final position – this gives fourth digit!

Sure, here are three popular FAQs with answers regarding unlocking any Master Lock with a simple 4-digit code:

Is it really possible to unlock any Master Lock with just a simple 4-digit code?

Yes, it is possible to unlock some models of Master Locks using a technique called “shimming.” This involves creating a shim out of thin metal or plastic that can be inserted between the shackle and the body of the lock to release the internal locking mechanism. The technique works on older model Master Locks that have a four-pin cylinder and not all locks can be shimmed.

Can I use this method on all types of Master Locks?

No, this method only works for certain types of six-pin tumbler locks from the company, which typically have an L-shaped mechanism inside. It may also work on other brands’ similar designs but results cannot be guaranteed.

Is this illegal or considered breaking and entering?

While shimming does involve bypassing security measures put in place by locksmiths, it is not necessarily illegal as long as you are using it legally (e.g., you lost your key) and are not causing any malicious intent like stealing etc.. However please note that we do not recommend attempting such tricks unless under expert supervision or without prior lawful consent from authorities if required .
