Bump key works best on high-quality locks as a result of the tumblers and cylinders move additional swimmingly. The majority locks operate an equivalent way: Tumblers are pins that are cut in 2 at totally different points, so the term, "pin stack." after you insert a key into a lock, the angular teeth aid in raising the pins to permit for ultimate rest at associate degree acceptable height within the natural depression. If you are mistreatment the proper key within the right lock, the divisions within the pins match-up with the highest a part of the cylinder, known as the shear line. Currently the highest pins are outside the cylinder and also the bottom pins are within, permitting the lock to show freely. After you bump a lock, the energy from the strike is transferred from the key, to the lowest pins, manufacturing enough energy to primarily bounce the highest pins outside the cylinder therefore the lock will flip.

Great job, well done  and i must say people, most of the problems people face while bumping is , they cant decide whether they have reached the sheer line or not, they keep on entering the key and rotating them in clockwise or counter clockwise direction without trying focus on the basic mechanism of the lock.

You are right. Rotating it clockwise or anti clockwise is not the solutions, try to understand its mechanism.

Well said. Understanding the mechanism and how the bumping technique works will be helpful specially for beginners. And then practice.Thank you for sharing :-)

Yes, your are right, its better to undertsand the mechanism of the tool you are going to bump
