What kind of security is the lock cylinder of the anti theft door?

Take the Saidian brand idling blade anti-theft lock cylinder produced by the expert committee of China's lock industry as an example, which is more intuitive. As shown in the figure below, there are several key points: first, the material should be good, the lock cylinder should be made of standard copper (brass above 59), the blade structure should be stainless steel, and the black paddle cam in the middle should have carburizing technology; Secondly, the process should be solid, which is not something that ordinary enterprises can do. Third, if it is a double-sided blade, in this case, it is more convenient to open and the anti-technology opening ability is stronger; If it is a marble, it must not be a standard marble, it must be a double row, with a curved groove or a special-shaped marble (it is easy to see on the key); Fourth, the backbone should be strong, and it is best to have an anti-breaking setting (high hardness ribs); Fifth:

If there are conditions to idle, this is not absolute, because idling is not something that ordinary manufacturers can produce. The technical competence of the process is very demanding. Finally, there should be anti-drilling measures at the keyhole, otherwise it will be easy to be drilled open.
