Problems solved by technology

The rapid development of modern science and technology has promoted the research and development of unlocking tools and the improvement of unlocking technology. The technical limit of single core lock is difficult to deal with unlocking technology (technical opening or destruction opening)

Although the anti-theft performance of the double-core lock is better, it only increases the difficulty of thieves' technical opening and violent opening compared with the single-core lock.
