One, what does "Super B-level lock" mean?
According to relevant regulations of China's "Mechanical Anti-Theft Locks" regarding the main technical indicators of mechanical anti-theft lock cores, China's national standards for locks are limited to Class A and Class B locks. Lock cores exceeding Class B are enterprise standards proposed by lock manufacturers, typically referring to locks that cannot be opened for more than 270 minutes due to technical limitations.
Two. Do locks with a Class B security rating provide effective theft protection?
According to data obtained from the police department, 90% of households use A-grade and B-grade lock cores. In burglaries, 66% involve forced entry using keys, with 58% of these occurring at night when residents are home and successfully using keys to gain entry. This is largely due to the poor quality of the lock cores and a lack of awareness among residents regarding security measures. Ordinary anti-theft door lock cores can be easily picked by burglars. Super B-grade lock cores utilize multiple anti-theft technologies and various anti-pulling mechanisms, providing a high level of security. These lock cores employ multiple irregular keys and combinations, capable of generating up to billions of unique key codes, enabling regional key sharing (with a probability of one in 1.6 billion), making super B-grade lock cores a more secure option.
Three. Can a locksmith who specializes in opening Class B locks open it?
It can be applied, but it is very difficult.
The key for super-b level locks utilizes a double-row, computer-designed, and composite curve-shaped key, with a technology that can achieve a lock-opening time of over 270 minutes. This is currently the safest lock, with a very low probability of being opened unless through forceful destruction. Even with destructive lock-picking attempts, it is very difficult to open.
