The easiest way to pick a Master Lock is by raking it. This is done by first tensioning the core and using a lock pick to bump all of the pins to the shear line. Master Locks can also be picked with a variety of makeshift tools including paperclips, bobby pins, soda cans, and even chicken bones.
A standard 40-digit Master Lock has 64,000 combinations which would take the average human about 180 hours to crack by using random combinations. This guide will aid you in reducing that absurd number to only 80 combinations and instruct you on how to crack a Master Lock in 10 simple steps.
No. Without the key number, there is no way for Master Lock to know which key will open your lock. There is not a master key that will open all Master Lock products.

Using specialised lock picks it is possible to manipulate almost every padlock to open. Due to their size, smaller padlocks contain fewer pins which inevitably make them easier to align and therefore pick. A 30mm padlock, for example, would contain about 3-4 pins.
Shackleless Padlocks
Contrary to the name, these actually do have a shackle, but the steel body completely encases it. No part of it is exposed, making it impossible to tamper with or cut the shackle. Shackleless padlocks are generally combined with a specific security “hasp,” or latch.
There are a ton of different types of lock picks that we can use, but by far, the best and easiest style of pick to use on a Master Lock is a rake.
Choose a padlock that features either carbide or alloy steel for the best security. The better the metal you have the more secure your padlock will be. Make sure you choose a thick metal like alloy but don't worry about its weight as this isn't always a sign of its strength.
