Check the dial and make a note of the number that it 'clicked' on then continue to gradually rotate that same dial to double-check (in my case dial 'C' was the hardest to rotate and it 'clicked' on '7'). Start to gradually rotate the dial that is the until you hear a resounding 'click' and feel the shackle move upwards slightly. If the lock is locked onto a solid object such as a gate or a door then a length of rope most likely won't be necessary as having it locked onto something gives you more control and grip thus meaning you will be able to complete the whole procedure with just your bare hands. When you feel the shackle move upwards slightly and release a 'click' you can move on to the next dial and repeat the procedure until all the dials on the lock have been completed and the lock has been cracked. Being able to apply strong even force on the shackle is vital in order to put a greater amount of friction on the locks dials so that when a dial is turned to the correct number it will result in a resounding 'click' and a slight upward movement of the shackle. A good grip is necessary because in order to crack the lock you will need to apply a strong and even upwards force on the shackle throughout the entire procedure and this can be difficult to obtain with just bare hands. When picking/cracking a combination lock a length of rope can be used to create a makeshift handle to give you a better grip of the lock. When the dials are moved or jumbled, the keyholes become dis-aligned and the toothed pin cannot be removed and is therefore locked in place. When correct code (in this case 9-2-4) is entered the keyholes of all the dials on the lock become aligned and toothed pin (second picture) can be inserted.

A combination lock (using a bike lock as an example as shown in the pictures above) has three or more dials with a keyhole through the centre of them.
