you cant you need to know the combo and have the lock open to access the combination change device if there was a way to reset a combo on a locked lock what kind of security would that be?
Some master locks are rekeyable, most are not.
I had the same problem. Turn the lock to 0000 then stab the button with a pen or pencil and hold it down as you turn the lock to the new combo. Ta da your lock is now set to the new combo. Good luck :)

Problems resetting and lock 3-dial combo lock
You cannot change the master code. You can add other codes, but you cannot change the master....
If you are unfortunate enough to have lost the combo - MOST common combination padlocks are cheap enough to just cut off and replace. Otherwise, call a locksmith and discuss the problem - if the lock is important and you want to save it they can help you out. You can also call Master Lock Co. Be prepared to PROVE the lock is yours with a notarized letter and some time on your hands to send it to them.
Go to main menu, push main menu, settings, phone lock, put in ur combo, and push change combination.
Master Lock was created in 1921.
The motto of Master Lock is 'Tough Under Fire'.
A Master lock is no different from any other lock. Using shims if it's a padlock, or picking it traditionally will open a Master lock the same as any other lock. In fact, Master locks are fairly easy to pick.
