At TOPLOCK there is a well-known story about the two siblings’ elder brother Mr. Liu and his younger sister Ms. Liu, a family with an extraordinary entrepreneurial spirit.

Mr. Liu, who is a die-heart fan of the locking mechanism, started his part-time business as a locksmith while being a worker in an electric lock factory in his hometown. Gradually Mr. Liu started to make locks by himself and open his own workshop in his thirties in the 1990s. After leaving the lock factory, he sold his own locks in his hometown.

After several years of development, Mr. Liu felt that the industry was prosperous and it was a good opportunity to expand the workshop. He persuaded his younger sister Ms. Liu, who had already been the sourcing manager in the state-owned enterprise, to quit the job and join in business together with her husband.

How to attract more customers to expand the sales volume became the main obstacle at the beginning of the new development. The two siblings and their spouses made a great bet on an important decision with the confidence in their locks, which costs almost all their family funds: They made several batches of lock samples and sent them to different target customers around the country for free. Ms. Liu and her husband also visited those valuable potential customers one by one by traveling nationwide. 

The quality of the locks produced was widely accepted in a short time after their on-site introduction. Increasing demand encouraged the new investments in the workshop: In the year 2000, they moved to its own new factory of 1,640 m2 in Zhongshan City, which is over 600km away from his home town and well known as “China Hardware Manufacture Base” and “China Lock Export Base”.

In 2006, the electrically controlled locks become the hot-sales items. At that time, the two couples made another critical investment. They incorporated another electromagnetic lock factory operated by a design engineer. By combining the increasing number of workers and machinery equipment, the consolidated factory was named “TOPLOCK”.

To this day, with over 30 years of personal design and lock industry experience, the co-founders have created a product portfolio with more than 300 models related to access control systems.

And now, when they don’t work in the factory, you will find Mr. Liu and the co-founder fishing from afternoon till night. This is another common hobby tying them closely besides locks.
