The security lock of the security door at home has hidden dangers. How can I change to a safe and reliable lock? Yesterday, the reporter interviewed the lock experts and the police to hear what they said.
A class lock is the most vulnerable to burglary
Many people have watched a wide-ranging video on the Internet or on TV programs - just put a layer of tin foil on the outside of the unlocking tool, and slam into the keyhole, turn a few times, "啪", thick The security door is open and the entire process takes only a few seconds. This video was confirmed by an unlocking expert. The technical specifications of the A-level lock: the anti-destructive opening time is more than 10 minutes, and the anti-technical opening time is only 3 seconds to 5 seconds.
Unlocking expert comment: Mechanical anti-theft door locks are divided into common protection level and high protection level, which are represented by A-level, B-class and C-level locks respectively. In order to prevent thieves from unlocking technology, it is best to buy high-level locks. In many residential areas, in order to save costs, developers generally install A-level locks for residents. According to incomplete statistics, most cases of burglary occur in households using Class A locks.
Upgradeable Class B lock: recommended to change the lock cylinder
Class B locks have a destructive opening time of more than 15 minutes and a technical opening time of less than 1 minute.
Unlocking expert comment: The more complicated the key, the safer the door lock. The lock cylinder of the security door can be identified by the number of marbles. In general, multiple rows of marble locks are superior to single-row marble locks, while multiple rows of invisible marble locks are superior to ordinary multi-row marble locks. From the perspective of the complexity of the key, the cost of the B-class lock is higher than that of the A-class lock, but with the development of the unlocking technology, the anti-theft performance of the B-class lock is getting worse.
For those who use Class B locks, experts recommend that if the lock can replace the lock cylinder, it is recommended to achieve better anti-theft performance by upgrading the higher-level lock cylinder.
The safest lock at the moment is the Super C lock.
The Super Class C anti-theft door lock is currently the safest lock. It uses the most advanced locking tool to prevent tampering, anti-twist and anti-technique.

At present, the super C-class lock cylinder on the market has a high safety level, technical unlocking cannot be opened, anti-tin foil, anti-collision key, anti-universal key, 360-degree idle blade side cylinder lock core and blade side cylinder lock core, any The keys can be inserted, but they cannot be hard to open.
