Index of selection
First, the lock body material this involves a lot of professional knowledge and the technology of various manufacturers, the mainland is generally made of iron, steel, stainless steel, zinc alloy, due to the process, cost limit, lock rod hardness is not enough, often easy to be cut by pliers, hydraulic pliers.
Two, the general people buy lock only look at the shape, think that the big must be good. But no matter which kind of domestic lock to buy, the lock core is generally copper, the characteristics of copper is soft, with electric drill, concentrated acid, you can easily destroy the copper lock core. There are also differences in the types of lock core, more commonly used for European lock core, in addition, there are American screw lock core, fire lock lock core, the latter two are relatively high security, American lock core used in high-grade locks, good quality, high safety, fire lock core used in fire lock, can withstand 975 degrees of high temperature 90 minutes, is a national mandatory special lock core.
Three, the key, lock there are a lot of keys, cross, round mouth, crescent, a variety of keys, many key material for copper or aluminum alloy, easy to be copied, better materials have steel, there are new electronic keys, high security.

Product Features
If the key rod is bare and toothless, such a lock is a magnetic lock. In fact, the whole key head is set with a sleeve. If you remove the sleeve, you can see that there are three to five small dots inlaid on it. Magnetic locks are unreliable and cross locks are easy to open. Special tools for opening magnetic and cross locks are available on the market. With such tools, a thief can open most magnetic and cross locks in a minute or two.
Computer lock compound lock is more reliable, computer lock is just a professional name, and not really use the computer to open the lock. There are three to five circular grooves on the computer lock key. These grooves are arranged and combined by the manufacturer with the computer, so they are called computer locks.
Different manufacturers, most of the computer programs are not the same, play out of the groove location, size, depth of nature is not the same, so its mutual opening rate is much lower than the cross lock, a word lock. Even a good lock picker takes about 10 minutes to open a computer lock.
There is also a kind of anti-theft door lock is relatively reliable, that is compound lock. The so-called composite lock refers to the combination of two or more different principles of the lock core on the same lock.
The most common composite lock on the market is a combination of a pin lock and a magnetic lock, known to professionals as a magnetic composite lock. To open the lock, you have to destroy the lock’s magnetism before you can technically open it.
But magnetic locks also have an Achilles heel. They can be demagnetized if the key is not properly kept, hit by gravity or exposed to high temperatures. Once it’s demagnetized, the lock won’t open.
