### How can i reset my master lock

The only way to open your lock is by using the correct combination. There is no other way.

You can either try every possible combination or you will need to contact the manufacturer. But they cannot assist you if the lock does not have a serial number (they recently stopped applying serial numbers for greater security) and they will not assist if the lock is already secured to anything. There are a number of other hurdles as well, click here for details. Given that they state that you will have to wait four to six weeks for an answer, it's going to be far quicker to just try every possible combination
