Tips and methods for judging the quality of anti-theft locks

1. According to the lock body material of the lock, it is judged: this involves a lot of professional 

knowledge and the technology of various manufacturers. The steel is generally made of iron, steel, 

stainless steel and zinc alloy. Due to the limitation of process and cost, the hardness of the lock rod 

is not enough. Cut by pliers and hydraulic clamps.

2. According to the lock core of the lock to judge: the average person buys the lock only to look at 

the shape, it feels great to be good. As long as you pay attention, no matter which kind of 

domestic lock you buy, the lock core is generally copper. The characteristics of copper are soft. 

With electric drill and concentrated acid, you can easily destroy the copper lock core. At present, 

the commonly used lock cylinder is a European lock cylinder. In addition, there is an American 

thread lock cylinder and a fire lock cylinder. The latter two are relatively safe.

3. According to the key of the lock, there are many keys to the lock. There are a lot of keys for the 

lock, the cross, the round mouth, the crescent, and the various colors are made of copper or 

aluminum-iron alloy. It is easy to be copied. The better materials are steel. There is also a new type 

of electronic key that is safer.

4. According to the thickness of the filler and the steel plate: you can look at the security door 

when you install it. Generally, the cat's eye is screwed off the door to see what is inside. If any cat's 

eye is already secure, it can't be screwed down. Can be seen when the security locks. The consumer 

can tap the security door with a hand, and the sound is sounded, indicating that the thickness of 

the steel plate is sufficient, and the filler is real. If the sound sounds "squeaky", it means that the 

thickness of the steel plate is not enough.

5. Locks are just a scorpion: locks are an important part of the security door. Many of the anti-theft 

doors sell their own anti-theft door locks when they are selling. In fact, this is just a scorpion to 

attract customers. The real good lock is not the more locks, the better. There are no essential 

differences between the four lock points and the 10 and 20 lock points. No matter how many lock 

points there are, the center is on the lock cylinder. As long as the lock core is broken, more lock 

points are useless.

6. Look at the production and sales license: consumers can check the relevant proof of the product, 

in addition to this production license, the manufacturer should also have the corresponding 

technical inspection certificate. Such as fire test report, seal test report, etc., so that you can have a 

general understanding of the technical performance of the product.
