3. When choosing a lock cylinder, look at the color, and compare the color with the workmanship. Good quality lock cylinders are electroplated, with a smooth surface and bright color. Among them, the dark yellow color is the copper core, which is relatively strong and has good anti-theft performance. The lock core is dark in color, and the gray color and bubbles are zinc alloy, which has average anti-theft performance.

After the key is inserted halfway, use 5 to 7 points of force to rotate clockwise or counterclockwise and continue to press the key into the lock. The key of the card shows that the lock cylinder has poor anti-theft function and successfully rotates in the half-rotation state. The lock cylinder shows that the anti-theft function is good.
