How to choose a door lock

1. Look at the "teeth" of the key. The more teeth, the deeper the teeth, the more complex the arrangement, the greater the difficulty of opening, and the better the anti-theft performance.

   2. Weigh the lock by weight, and compare the weight to the lock cylinder. The heavier the weight, the better the quality of the lock cylinder. The more beads inside the lock cylinder, the better the anti-theft function.

   3. Choosing a lock cylinder depends on its color, color, and workmanship. The high-quality lock core adopts electroplating treatment, with a smooth surface and bright color. The copper core with a deep yellow color is relatively sturdy and has good anti-theft performance. The lock core has a dull color, while the zinc alloy with gray white and bubbles has average anti-theft performance.
