If you are doing it right you will feel the tip of the hook traveling over the tops of the pins. If you get the pressure on the hook and the wrench right, each pin will hang up at its shear line and the lock will open.
Two tips:
1) After you've pulled the hook over all four pins, back the pressure on the wrench off a tad to let just one or two pins pop back up. The first ones to pop are often the ones that have been pushed down too far.
2) If the lock won't open with tension in a clockwise direction, try putting tension on in a counterclockwise direction. Sometimes things are a lot easier in reverse.
this is what i do too...tip #1 is very useful
