Good security performance

After professional security testing and certification, the lock core can resist technical opening time of more than 30 minutes, and can effectively resist common technical unlocking methods such as locksmith tools and pressure tools. In terms of mechanical properties, the anti-drilling time can reach more than 10 minutes, and the tensile strength exceeds 1000N. This means that in the face of external malicious intrusion, the lock core can gain valuable emergency response time for users. For example, in some theft cases, criminals use technical unlocking methods to try to open the door lock. High-performance lock cores can delay the unlocking process and increase the risk of being discovered, thereby effectively protecting the safety of the internal space and reducing the chance of property being stolen.

Strong durability

The lock core has undergone rigorous durability testing. In the test simulating the daily use environment, after completing more than 50,000 opening and closing actions continuously, it can still stably realize the opening and closing functions, and there are no obvious signs of wear on the key internal parts. In actual use scenarios, based on the frequency of unlocking and locking about 10 times a day in an ordinary household, the lock core can be used normally for more than 10 years. This strong durability reduces the frequency of users replacing lock cores, reduces subsequent maintenance costs and energy investment, and users do not need to worry about the performance degradation or failure of the lock core due to long-term use, and it protects the safety of homes, offices and other places in a long-term and stable manner.

Flexible customization services

Provide comprehensive customization services, covering materials, sizes, surface treatments and key management systems. In addition to conventional brass materials, special materials such as stainless steel and various alloys can also be used to make lock cores to meet the special needs of different users for material performance. The surface treatment color can be customized according to user preferences, such as antique bronze, matte black, etc., to provide users with personalized choices. The key management system can customize functions such as master key, general key, and identical key according to the management needs of different places. For example, in a hotel scenario, by customizing the key management system, the hotel can set keys with different permissions for guest rooms on different floors and different room types, while managing them uniformly through the general key, easily realizing hierarchical control of key permissions and meeting the personalized management requirements of complex places.
