How to distinguish the level of anti-theft door lock cylinder? The level of anti-theft door lock cylinder is directly related to the safety factor of home or office. Generally speaking, the levels of anti-theft door lock cylinders are mainly divided into level A, level B and level C. Each level has significant differences in structure and security.

The structure of Class A lock cylinder is relatively simple, mainly using single-row pins or cross lock structure, with few and shallow key slots, high mutual opening rate, and short technical opening time, usually within 1 minute. This type of lock cylinder has poor anti-theft effect and is gradually not recommended for use in places with certain security requirements.

Class B lock cylinders are improved on the basis of Class A. They mostly use a double-row pin structure, the key slot is more complex, and the technical opening time is extended to more than 5 minutes. Class B lock cylinders mainly include three types: computer double row, double row crescent, and double-sided blades. They have a low mutual opening rate and significantly improved resistance to technical opening, and are suitable for the security needs of general residences.

C-class lock cylinder is one of the types of lock cylinders with relatively high security performance on the market. It adopts complex structures such as multi-directional pins and side columns, with many key changes and technical unlocking time usually exceeding 270 minutes. It has strong protection against common technical unlocking methods.
