In a recent demonstration, a professional locksmith showcased how quickly ordinary door locks can be opened using advanced techniques. The process, which took only a few seconds to a couple of minutes, highlighted the vulnerability of standard locks and emphasized the importance of choosing more secure options.
The demonstration took place near Yunnan North Road in Gulou District, where I met Chen Wei, a licensed locksmith with over a decade of experience in emergency lock-opening services. Alongside his assistant, Chen Daochun, he demonstrated two different methods of unlocking a regular door lock.
First, Chen Daochun used a tin foil technique, which involved inserting a thin strip of metal into the lock cylinder. After several attempts, the lock was successfully opened within three minutes. This method, while not the fastest, still proved effective against basic locks.
Next, Chen Wei demonstrated a more advanced technique using a specialized tool resembling an "ear spoon." With just a few movements, he managed to open the lock in under 10 seconds, showcasing how easily some common locks can be bypassed by trained professionals.
Chen Wei explained that many household locks are classified as A-level or B-level, both of which have relatively weak anti-theft performance. A-level locks, for example, can be opened in just a few seconds by experienced individuals, while B-level locks may take a bit longer but are still vulnerable to skilled technicians.
To enhance home security, police officials recommend upgrading to Super B-class locks. These locks feature more complex key mechanisms and are significantly harder to tamper with. According to Chen Wei, even the most skilled locksmiths would struggle to open a Super B-class lock in less than an hour.
Currently, only about 10% of households use Super B-class locks, despite their superior security. While these locks are more expensive—ranging from 300 to 400 yuan compared to 100 to 200 yuan for standard models—the investment is worth it for those looking to protect their homes.
Beyond traditional locks, there are also high-tech alternatives such as fingerprint locks, password locks, and iris recognition systems. While these offer convenience and modern features, Chen Wei pointed out that their security still depends on the quality of the lock core. Even the most advanced locks can be compromised if they use low-grade components.
In conclusion, the police strongly advise citizens to prioritize security when choosing door locks. Upgrading to a Super B-class model can significantly increase the difficulty of unauthorized access and provide better protection for personal belongings and family safety.
