Decoding Master Combination Padlock (Model 1178)

Master Lock’s Model 1178 Pro Series combination padlock is a popular choice for many, but it may not be as secure as you think. In this article, we’ll explore two easy methods to open this lock – one using a tool and one involving touch and manipulation.

First, let’s discuss the touch and manipulation method. To start, pull on the shackle, which pushes an internal fork against the back of the wheels. Once they’re binding, test each wheel to see how much movement it has. When you find a digit with more movement than the others, you’ve identified a digit of the combination. Repeat this process until you’ve determined the full combination and the lock opens.

The second method involves using a notch decoder tool. Insert the decoder along the right side of the code wheel and turn the wheel until the decoder falls into a deep notch. Once you’ve aligned all the notches, move each wheel down six positions to reveal the combination.

While the Master Lock Model 1178 may be popular, it’s important to note its lack of manipulation resistance. As demonstrated, it only takes a minute or two to decode and open the lock. When choosing a padlock, consider security features and resistance to manipulation to ensure your belongings stay safe.
