The difference from the A -level key is that there is an extra row of curved lines in the key. 3 种,电脑双排锁芯、双排月牙锁芯、双面叶片锁芯。 There are three main types of lock cylinders , computer double-row lock cylinders, double-row crescent lock cylinders, and double-sided blade lock cylinders. 5 分钟内,互开率高,通过强扭工具, 1 分钟可以开启锁芯,一般在小区里多数统一配置的锁芯多为防技术开启低的 A 级或 B 级防盗锁芯。 The anti-technical opening time is high within 5 minutes, and the lock cylinder can be opened in 1 minute by using a strong twisting tool.

A 级锁芯防技术开启时间为 1 分钟, B 级锁芯开启时间为 5 分钟。 According to national standards, the opening time of Class A lock cylinder anti-technology is 1 minute, and the opening time of Class B lock cylinder is 5 minutes. A 级防盗锁芯在反锁的状态下,小偷使用锡纸配合工具,短短几秒就可以开启。 In just a few minutes, it is impossible to fight against the high-intelligent unlocking tools currently used by thieves.

为锁欲为

270 分钟无法技术开启,区域互开率为零,(一千六百万分之一)。 The shape of the key is a single-sided blade inner or outer slotted key. The type of lock core is an edge cylinder lock core. It cannot be opened technically after 270 minutes of inspection by the Ministry of Public Security . The regional mutual opening rate is zero. ). V 型边柱锁定,如果用强扭工具开启锁芯,锁芯内部破坏,自爆锁死,导致无法开启,因不易开启,防盗系数最高,家庭防盗推荐使用超 B 级锁芯。 The marble structure is double-row blades and V -shaped side column locks. If the lock core is opened with a strong twisting tool, the lock core is damaged internally and explodes and locks up, causing it to fail to open. Because it is not easy to open, the anti-theft coefficient is the highest. It is recommended to use a super B class for family anti-theft Lock cylinder.

You can distinguish based on the following points:

“牙齿”。 1. Look at the "teeth" of the key . The more teeth, the deeper the teeth, the more complicated the arrangement, the more difficult it is to open, and the better the anti-theft performance.

2. Picking locks weighs two, one looks at the lock core compared to the other. The heavier the weight, the better the lock core quality, the more beads in the lock core, the better the anti-theft function. Select the lock cylinder to see the color and the workmanship. The high-quality lock cylinder is electroplated, with a smooth surface and bright color. Among them, the darker the yellow is the copper core, which is more sturdy and has better anti-theft performance.
