Maintenance of anti-theft Lock
- Oct 11, 2017 -

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, the better the anti-theft performance.

2. Pick the lock on the weighing of two, a specific proportion of the second look at the lock core. The heavier the weight, the better the quality of the lock core, the more beads inside the lock, the better the anti-theft function.

3. Choose the lock core to see the color, compared to the color. Good quality of the core with electroplating treatment, smooth surface, bright color. The color deep yellow is the copper core, more solid, anti-theft performance is better, the lock core color is dim, the color of gray bubble is zinc alloy, anti-theft performance generally.

4. The key rotation inserts the lock core by the card the anti-theft performance is bad, after the key is half inserted, use 5 to 7 minutes to rotate clockwise or counterclockwise and continue to press the key into the lock, the key of the card to show that the lock core anti-theft performance is poor, smooth in the half rotating state into the lock core of the description of anti-theft effect is good.

In peacetime life also should pay attention to the maintenance of household locks. The exception if the home must unlock locks, must find the public security organs to record the normal units, and check the Unlock personnel qualification, should not be greedy to believe that the door casually posted ads, resulting in the installation of the lock or key to steal.
