The chewing gum can also be unlocked. It is very rare to listen. The reporter tried Baidu a bit, but found that similar cases have occurred frequently in the country in recent years, but it is rare in Hangzhou.

This kind of lock is too technical, why can the gum be unlocked, and what kind of lock is more reliable?
Chewing gum open cross lock success rate is relatively high
According to the police, the principle of chewing gum unlocking is very simple. Criminals use tools to squeeze the chewing gum inward through the keyhole. When the chewing gum is filled with the locking hole, the bullets in the locking hole will be squeezed into the bullet hole, and all the squeezed out. The lock cylinder cannot be restored and the lock is opened. The criminals then use special tools such as metal sheets or wires to squeeze the gum and unlock it.
The police told reporters that the general anti-theft door of the cross-shaped lock is easy to open, and the one-shaped anti-theft door lock is more difficult to open. Since the one-line anti-theft door lock is more common now, the success rate of the chewing gum unlocking method is not high, often a dozen or so. The lock can be successfully opened up to two or three.
Lock only two national standard B level is more insurance than A level
Usually, people pay more attention to the shape of the brand when selecting the security door, but rarely pay attention to the quality of the lock is the key to the security door. At present, the technical standards of the mechanical anti-theft lock are only two national standards - A and B, of which A The level lock prevention technology opening time is ≥1 minute, and the B-level lock prevention technology opening time is ≥5 minutes. The so-called technology opening means that the locksmith and other people who have unlocked the technology can open the anti-theft door lock without any trace.
That is to say, there is no lock that cannot be opened. The key to the quality of the lock is the length of time when the technology is turned on. However, a master of unlocking told reporters that although the A-class lock is qualified according to national standards within 60 seconds, with the spread and development of unlocking technology, professional unlockers can open one in 30 seconds or even seconds. Put the A level lock.
Therefore, the police reminded the public to use safe door locks and improve their vigilance. When they found that the door locks in their homes were stuffed with chewing gum or cotton, they should promptly report this to the community security or public security organs.
