A locksmith will be able to provide the combination from the code number stamped on the back of the lock.
No
If you do not have the combination, there is no way to open the lock. A master combination would defeat the purpose of having the lock.
With the combination
my receiver is lock i want to open i dont know how can i open because i forget 4diget lock nomber what is the master code thanks
You have to have a combination. If you have a key lock you don't need a combination, all it is is a lock that says master and a key to turn it and then it opens what you have in it.
There is no "master combination" that can open any lock. There would be no use for the lock if that were the case.
It will come with a slip of paper that has the specific combination to that lock. Each individual lock has it's own combination.
That depends on the specific kind of lock.
Set the dial to the combination, pull out the shackle and turn it 180 degrees. Then press the shackle in and turn 90 degrees, and turn the dials to the combination you want. Turn the shackle back, careful not to move the dials. Remove the shackle again, then push in until locked. Be sure to check your combination.
don't now and don't care
