Put Up Clamp
The first step is to putting up the metal clamp on the lock, as without it you can start processing of breaking the lock, which comprises the process of determining your combinations keys.
Turn Combination Clockwise
You should turn the combination portion of the lock clockwise, and keep doing so until you hear a click sound. This is where you leave the combination portion. Do not move a number before or after the click sound, and then turn the dial towards the right direction, only two more numerical places. This is the first number of your three combination keys or numbers.
Turn Dial Left
While holding the metal clamp upward, you should turn the dial portion towards the left until it stops. This is your second number of the three combination numbers. Remember the numbers identified so far carefully. You can also write them down in case you forget them.
Opening of Lock
Turn the dial portion towards right again, without leaving the clamp down. Keep turning the dial to right until the lock opens. The number at which the lock opens or the dial stops is the number of your combination.
You can also use some of conventional techniques to break open the lock. Use bolt cutters to cut through the metal part of the lock. You can do this easily and without much damage to the lock of the safe or the material stored in it.
You can also use hammer to break the lock. Bang the hammer and aim on top of the curved portion of the lock and exert as much pressure as you can, and if you do so it will release the lock in a matter of time. The basic of the technique is to put the pressure right on the top of the curved portion of the lock.
