You can not reset your lock combination without knowing the original combination you had set.
If you have forgotten your lock combination, then there are 2 solutions.
1. You could use Bolt Cutters to break the Lock open.
. Sometimes, the simplest solution is often overlooked, as your lock is
a 3 digit combination lock, and if you have about 30 minutes to spare,
then why not try all the possible combination from 000 - 999 ( 000,
001, 002, 003 through to 999) You may think this will take a long
time, but it should not take you more than 30 minutes and if the first
digit of your forgotten code starts with a 0, 1, 2, or 3.. then it will
take significantly less than 30 minutes. Try it out, as it will save
you from having to buy a new lock if you use bolt cutters.
