How to identify the lock cylinder of the fingerprint lock?

Sep 16, 2019

Why is it that the A-class and some B-class lock cores have low anti-theft performance? The “Twisted Paper Unlocking” program reported by Zhejiang Satellite TV, a 10-year-old child, can open most of the A-level locks simply by mastering the tool. Therefore, for the fingerprint lock, if you find that the lock cylinder is actually A-class, then please do not buy.

The lock cylinder (or key) is the most obvious part of checking whether an entry door lock passes. The Ministry of Public Security now has two levels of A/B. Since the network and some entities have liked to use the concept of Super B in publicity, they are compared as follows: A, B, and Super B. At present, household door locks are generally divided into three levels:

One: Class A, with technology open for more than 1 minute as a qualified standard.

Two: Class B, with the technology open for more than 5 minutes as the eligibility standard.

Three: Super B grade, the lock cylinder is monitored by the relevant department with the technology unable to open or the technology open for more than 270 minutes. At present, there are many types of super B-class lock cores on the market. (Enterprise standards, no national standard.)

Summary of the lock core:

As soon as we look at the key structure is complex enough, at least let the seller promise to achieve the so-called "super B level" on the market;

Second, let the seller take out the fingerprint lock lock core. If you can't get it, ask the seller to take a look at the front panel. (The keyhole is at the bottom of the lock, most of which are not up to standard)
