The secure lock cylinder has been upgraded to B-level and super B-level, so choose super B-level when purchasing.
In the past, when buying a lock, the quality of the lock core was judged by the number of key teeth, mainly by the structure of the lock core. The blade edge column structure is often much better than the traditional marble structure. When choosing a lock, it is better to consult a professional teacher and then choose according to the situation.
Second move: Pick the lock and weigh it by weight, compare the weight and look at the lock core. The heavier the weight, the better the quality of the lock core, the more beads inside the lock core, and the better the anti-theft function.
The third trick: Choose the lock core based on color, and compare the color to the workmanship. High quality lock cores are treated with electroplating, resulting in a smooth surface and bright color. The copper core with a dark yellow color is relatively sturdy and has good anti-theft performance. The lock core has a dull color and a gray white color with bubbles. The zinc alloy has average anti-theft performance.
Fourth move: The anti-theft performance of the lock cylinder is poor when the key is rotated and inserted. After the key is partially inserted, use 5 to 7 force to rotate clockwise or counterclockwise and continue to press the key into the lock. If the key is stuck, it indicates that the anti-theft performance of the lock cylinder is poor. If it is successfully inserted into the lock cylinder in a semi rotated state, it indicates that the anti-theft effect is good.
