Anonymous users2024-01-24Dear, I haven't heard of the Flying Fish brand anti-theft door lock, but in my years of experience, the anti-theft level of the general (except for some special real estate) engineering door locks is not high, basically A-level or quasi-B-level, B-level are very few, super B, C-level is basically not visible. Therefore, it is recommended to send a picture in person, or if it is a door lock that was given when buying a house, replace it.
Did mine help you?
Class B is the safer level and requires skilled workers to turn on within 10 minutes. Super B-level can not be technically opened after 270 minutes of detection by the department, which belongs to the lock cylinder with high security, and at present, super B-level and C-level are the same thing.
It's really hard to distinguish between this, because even B-level is divided into many kinds, and if it's the kind of pure double-row marble, it can also be called B-class, but it can't play an anti-theft role in real life. What's more, developers of new communities will generally only choose double-row marbles if they don't care about the cost. The normal vast majority of them choose A-level locks (all understand, the cost factor). >>>More
Hello, now the lock cylinder, B-level is not very safe, super B-level or C-level is recommended. The price is around 200-300. You can contact the local regular lock picking and changing company (you can call 110 to consult) for replacement. It's convenient and safe. >>>More
Class B cylinders are superior to Class A cylinders. As for whether the thief can open it outside, there are probably several situations: the technical one who knows how to open the "cable" knowledge and essentials can be opened in a few minutes; Non-technical thieves are generally not pohuai, and the "rope" cannot be opened. >>>More
In terms of level, grade C is better.
If it's a miscellaneous B rank or a miscellaneous C grade, you don't dare to compliment. >>>More
