How to judge whether the lock core is really anti-theft according to the key of the anti-theft door lock?

The lock is to prevent the gentleman from stealing, and it is useless to steal. Personally, I have been buying the key of Hong Kong Jiuniu, and the corresponding lock is also a Kabbah lock. It has a double row of marbles on the front and a centipede-like sink on the back, which adds a row of marbles and a sink to the No.3 key and greatly increases the difficulty of opening. It's just that the one on the left is a multi-track C-level, and the one on the right is a four-dimensional slotted C-level, so the levels of these two keys are the same. To see the anti-theft coefficient, it is necessary to determine whether there is a corresponding gear in the lock cylinder and which key is released first.

There is a row of marbles and an S slot on the key, but if this S slot is fake (beautiful but useless), the natural opening time will be short. Among them, the copper lock core is divided into eccentric lock core and central lock core according to the different functions of anti-theft lock, and the eccentric lock core is more used in anti-theft doors. Let's talk about the safety of the chip lock core first. If you don't know the key, you can compare the key embryo with the key outside. If the grooves are the same or similar to those embryos, the anti-theft level is basically poor, and Super B: is the safest level at present. From the key point of view, there are generally double-sided double-row bullet slots with blades or curves next to them, and the technical standard for lock core design is more than 270 minutes. Its lock core is used more in the financial industry and less in civil use. The level of anti-theft ability here is very strong, making people's home environment safer.

No lock can be called safe. If there is, I think it is safer to brush the face lock. Some individuals suggest that China should refuel as long as the service is good and the installation is good. Domestic first-and second-tier brands include: Cadiz, Deshiman, Asia-Pacific Tianneng, Yarraa, Samsung, Luke, Xiaomi, 360, Black Dragon, Shimao, Haolishi, Julius, Zhongheng and Goldfinger. Among them, the pearl technology in pearls is recognized as the best lock core for anti-theft technology in the world, and the anti-theft technology of pearls and blades in pearls can actually be opened for 270 minutes. Suggestion: The safety factor is high and it can be used continuously.
