As the saying goes, "a key opens a lock", it not only refers to the uniqueness between the key and the lock, but also shows the safety of the lock. Recently, Xiao Bian visited the market and found that it is not uncommon for an ordinary key to open multiple locks, especially between those locks of the same model.
According to industry insiders, there are some low-quality and low-quality locks on the market. The production process does not meet the standards at all, and the anti-theft performance is extremely poor. Their existence has jeopardized the development of the entire lock industry.
The relevant departments also remind consumers that when purchasing locks, they should choose products from well-known and formal enterprises. At the same time, if property damage is caused by the quality of the lock, the victim can use the legal evidence to investigate the responsibility of the dealer or the production enterprise.
The more "universal" the lock is, the more inferior the key?
Why are some locks so "unsatisfactory"? With the "master key", can the "lock general" guarantee our safety? The long history of the development of locks is full of the game of "attack" and "defense". Now the quality problem of the lock, the most outstanding performance is the high mutual opening rate, a key can open several locks at the same time.
The manufacturing process of the lock is very complicated, and a small part that looks like a light weight has dozens of processes.
In the lock groove produced in the early years, there is a hard-proof iron bar that is not plucked. The key that is not matched can not be inserted into the lock core. Even if the ball inside the lock can be turned to the side, the lock core cannot be opened. The locks of the regular lock factory will take into account the anti-theft nature. The locks are equipped with several "anti-floods" in order to disable some special tools, unless it is brute force, it is difficult to open the lock. However, in order to save costs, some non-standard locksmiths have “conserved†this hard iron strip, which is even more excessive, and some even ignore normal marbles.
The anti-theft function of the lock is on the arrangement of the marbles of the lock cylinder. An important indicator for measuring the performance of the lock is its key amount, that is, the non-repetition rate of the arrangement of the marbles. Dai Genchao said that in order to reduce the mutual opening rate, the regular lock factory will develop a table of marbles with thousands of different arrangements before production. Locks produced by the same lock cylinder with the same lock core mold cannot be sold to the same area according to regulations. In order to save trouble, some small factories have only a few hundred or even dozens of combinations. In this case, it is not surprising that the lock opening ratio produced is high.
There are indeed unlocking tools. On the one hand, the lock factory is to improve the technological innovation in order to study the weakness of the lock; on the other hand, it is the customer demand, in case the key is lost in case of emergency.
