at present, the door lock cylinders in the market are divided into class A, class B, super class B, etc. "Consumers can identify the quality of the lock cylinder by the number of rows of marbles. Generally speaking, multi row marbles locks are better than single row marbles locks, and multi row invisible marbles locks are better than ordinary multi row marbles locks." Experts told the editor that the cost of class B lock cylinder is much higher than that of class a lock cylinder. Therefore, most lock brands in the market launch products of class a locks. "If the anti-theft door key has only a row of marbles, it is basically A-level lock cylinder. If you feel it is not safe enough, you can replace it with a B-level or super-b-level lock cylinder to improve the overall anti-theft performance of the anti-theft door."

material and workmanship are also important

"in addition to the lock cylinder, the quality of door and window hardware accessories is also critical." Many people say that locks are generally made of aluminum alloy, stainless steel and copper. Among them, aluminum alloy is the worst in strength and durability, and copper is the best, but the price is also higher. "It is also a copper lock. The workmanship and quality of various brands are also very different, which is difficult for ordinary consumers to distinguish." The salesperson said that the only way for consumers to buy "reassuring locks" is to compare them more. The locks of big brands are fine and closely sewn, and the workmanship of low-end locks will appear rough. In addition, the sound of good locks is mostly crisp when opening, while the low-end locks will appear loose when the key is inserted, and the sound is mostly dull when opening

the door lock needs to "change the heart" every five years.

"generally, the lock cylinder will wear naturally as the service life of the lock is long, and it is easy to be opened by keys with similar tooth shapes." A teacher with a key in a nearby lock said that the lock cylinder of an ordinary door lock must be replaced after five or six years of use

baogao hardware reminds the owners that the anti-theft doors and locks in many communities are uniformly purchased and installed by real estate developers, and most of them are not locks of particularly good quality. "If the same type of door locks are used in a large number in the same community, theoretically, the probability of" opening several doors with one lock "will increase. Many new residents in the community report that they often go to the wrong unit, open the door and find that it is not their own home. " The editor reminded netizens that if the lock cylinder is not replaced for a long time, there will be more serious potential safety hazards

with a long service life, the lock cylinder will naturally wear out, and it is easy to be opened by a key with similar tooth shape. If the lock cylinder is not replaced for a long time, there will be more serious potential safety hazards, and it is very likely to open several doors with one lock. Therefore, the quality of hardware door locks must be guaranteed to avoid unnecessary trouble
