The birth of Chinese locks has been going on for thousands of years. The wooden locks were found in the ruins of the Shu culture. The bronze locks appeared in the Western Zhou Dynasty. Metal locks were commonly produced and used in the Eastern Han Dynasty. The ancient Chinese lock has not only practical value, but also a precious historical evidence. It reflects the historical development track of woodworking crafts and hardware crafts from one aspect. At present, the annual sales of the Chinese lock industry is about 40 billion yuan, and the output is 1.9 billion. According to customs statistics, the average annual export growth rate of the lock industry during the “Eleventh Five-Year Plan” period reached 31%, which is twice the average growth rate of the hardware industry. In the first half of 2011, the export value of locks was US$2.082 billion, up 15.9% year-on-year. According to this calculation, the annual export volume was about 4.6 billion US dollars; the import value of locks was 273 million US dollars, up 16.2% year-on-year. Will reach $ 550 million.

  With the development of technology, the demand of the market has gradually changed from the traditional metal lock like smart lock and electronic lock. The electronic code lock is an electronic product that controls the circuit or chip operation (access control system) through password input, thereby controlling the closing of the mechanical switch and completing the unlocking and locking tasks.

However, in countries such as Europe, America, Japan and South Korea, electronic smart locks have become very popular, and their share in the civilian market has reached a certain height.

  In China, the overall level of password locks is still in the international 70s. The cost of electronic code locks is still very high. The market is still dominated by push- button electronic locks . The push-button and card-key electronic locks have been introduced to the international advanced level. However, the electronic lock developed by the country itself has not yet formed its market structure, and its application is still not extensive. Although in the Chinese market, electronic locks only account for less than 2% of the market for civilian locks, electronic locks will also be developed in commercial terms as they enter the office area, bank financial keypad electronic locks, biometric locks, etc. At the same time, it will also have a great impact on our civilian market.
