Anonymous users2024-01-23There are many types of locks for anti-theft doors, according to the principle of the lock cylinder, anti-theft door locks can be divided into marble locks, blade locks, magnetic locks, IC card locks, fingerprint locks, etc., the following is a brief introduction to several types of anti-theft door locks. Bullet locks and magnetic locks are more common. Like slotted locks, cross locks, computer locks, etc., all belong to bullet locks; Magnetic locks were more popular in the past few years, but they are relatively rare in these two years.
If the keybar is smooth and toothless, and it is inlaid with three or four small dots, such a lock is a magnetic lock. Industry insiders believe that the magnetic lock is very unreliable, and the opening of the cross lock is very convenient. Special tools for opening magnetic locks and cross locks are now available on the market, with which thieves can open most of the magnetic and cross locks in a minute or two.
Computer lock composite lock is more reliable, computer lock is just a professional name, not really use a computer to unlock. There are three to five circular grooves on the computer lock key - it is said that these grooves are arranged and combined by the manufacturer with a computer, so they are called computer locks. Different manufacturers, most of the programs used in the computer are different, and the position, size, and depth of the groove are naturally different, so its mutual opening rate is much lower than that of the cross lock and the word lock.
Even if you are a master of lockpicking, it takes about ten minutes to open a computer lock. There is also an anti-theft door lock that is also more reliable, that is, the composite lock. The so-called composite lock refers to the combination of two or more lock cylinders with different principles on the same lock.
The most common composite type lock on the market is a combination of a bullet lock and a magnetic lock, which professionals call a magnetic composite lock. To open this kind of lock, you must first destroy the magnetic properties of the lock, and then you can technically unlock the lock. However, magnetic composite locks also have an Achilles' heel, which can be demagnetized if the key is not kept properly, is hit by gravity, or encounters high temperatures.
Once demagnetized, the lock cannot be opened.
