Renting a house "fire" gives birth to a lock "hot" What is the safest lock cylinder?

"The first thing to rent a house is to change the lock core." Miss Liang told reporters. The reporter visited some lock-up shops. Most of the operators said that the business in the past two months was good. A second-hand house agent, Mr. Mu, also introduced the contrast between the house and the house that was not warm after the holiday. Recently, he rented it. Going out to a lot of houses, the fiery heat of the rental market will naturally drive the demand for locks. Mr. Mu also said that the average tenant will not change the lock, but only change the lock core to ensure the safety effect, but also save money and trouble.

What is the safest lock for the lock cylinder? The reporter interviewed a lot of people randomly, and most of them did not understand very well. "Thirty or forty yuan can be used." "As long as it is the door, it should be almost the same." The reporter heard a lot. Master Zhou, who has more than ten years of experience in unlocking and repairing locks, reminded the public that although the bridge section of "a pack of instant noodles unlocked" is a joke, the safety factor of different lock cylinders is indeed different.

Master Zhou introduced: In general, Class A is the most primitive and most unsafe lock cylinder. The owner's key is flat. There are only single-sided single-row bullet slots. Some cross keys are also classified as Class A. It can be opened in about minutes, and the familiar hand will be faster; the B-class is a safer level. From the key, it is a double-sided double-row bullet slot. If there is a tool, the skilled worker should open it in about 10 minutes; the super-B lock It is the safest grade at present. From the key, the double-sided double-row bullet slot is next to it, and there is a blade or curve next to it. The design standard of the lock cylinder should be more than 280 minutes. The general skilled lock master should also spend a new time. Take hours. Master Zhou reminded the public to try to choose a super B-class lock, and to find a regular company to install.
