Hooply - Armored Door Locks

Zhejiang Hongli Locks Co, is based in China. They are a well known manufacturer of some interesting high security lock products that differ greatly to mainstream products found in the USA.

Pictured below, is a version of their armored lock. This virtually impregnable door lock is a mortice lockset comprising 6 stainless steel round bolts and a latching mechanism.

They produce Hooply, Cefiro and Mingbang as their 3 primary brand lines.

The company employs about 800 people and continues to be a dominant player in the Asian high security lock manufacturing industry.

The cylinders used in these locks are known as lever type locks. They use double sided mortice bit keys (skeleton like). This means they are 100% bump proof and very difficult to pick.

Even duplicating these keys is a chore.

I have duplicated similar types of these keys, early in my career and I know they are very exact with very tight tolerances. They are usually required to be copied by hand, because finding suitable duplication machinery is not only difficult but incredibly expensive.

I remember being required to fashion a blank by braising a flag to both sides of a steel stem. Then gently filing the blank until it was similar in shape to the original.

I worked with a very learned professional, early in my apprenticeship, who taught me to use putty (plasticene) or play dough to form a mould around the original. I was then able to create a perfect duplicate using the mould as a guide.

Difficult and time consuming, the reward was customer satisfaction and the knowledge that the key worked perfectly the first time it was tried.
