Miss Chen wants to replace the second-hand house security door lock core, so she bought a lock core in Taobao. Since she would not install it, she found a special unlocking company technician to install it. The king of the lock company installed the lock cylinder. I found that this lock cylinder is not a genuine anti-theft door lock core. On the spot, I demonstrated the method of opening this fake lock cylinder. Ms. Chen saw that she was very surprised. In ten seconds, Master Wang opened the lock core that she bought online. .
Buy anti-theft door lock core to guard against counterfeiting
If you buy a genuine anti-theft door lock core, the thief wants to open it through the technology can not do it, it can completely resist the thief's technology unlocking. Xiao Bian suggested that you go to some formal physical stores, if you want to buy online, you can buy it in the Tmall flagship store of the brand security door lock core to protect your own interests. The security door lock core bought in the regular store, the structure and material are completely different.
Security door lock core anti-counterfeiting
Super B-class anti-theft door lock core is the safest
Now the original lock core for the security door on the market, the basic anti-theft function is relatively general, the quality of the door is very good, but the anti-theft technology of the lock core is relatively backward. The anti-theft door lock cores currently used on the market are basically divided into three levels, namely, A-class, B-class, and super-B-class. Among them, the anti-destructive opening time of the A-class lock cylinder is greater than 15 minutes, and the anti-technical opening time is greater than 1 minute. The anti-destructive opening time of the B-class lock cylinder is greater than 30 minutes, and the technical opening time is greater than 5 minutes. The anti-technical opening time of the super B-class anti-theft door lock core is more than 4 hours. (Note: “Super B grade†is an enterprise standard, not an international standard)
Identify the lock core level from the key
Xiaobian summed up three points:
1, the reason why the security door is not anti-theft is mainly the lock core technology, so the key is to choose a good lock core.
2. The structure and technology of the lock cylinder determine the level of the anti-theft coefficient. At the same time, it is the key to identify the true and false lock cylinder.
3, the selection of the purchase channel of anti-theft products should be cautious, can not be sloppy, to protect their own vital interests.
Finally, tell everyone a trick: When you insert your lock into the lock cylinder half, if you can easily push the key, it means that your home lock is relatively new, the anti-theft level is relatively high, if you can't push it in, it means your home lock. It is old and must be considered for replacement.
