Computer lock composite lock is more reliable
Computer lock is just a professional name, not really using 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 computers, so they are called computer locks.
Most of the programs used by computers are different from different manufacturers. The position, size and depth of the punched groove are naturally different, so its mutual opening rate is much lower than that of cross lock and word lock. Even if you are a master at unlocking, it takes about ten minutes to open a computer lock.
Another kind of anti-theft door lock is also more reliable, that is, 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 common compound lock on the market is the combination of marble lock and magnetic lock, which is called magnetic compound lock by professionals. To open this kind of lock, you must first destroy the magnetism of the lock, and then you can technically unlock it.
However, the magnetic composite lock also has a fatal weakness. If the key is not kept properly, it will be degaussed by gravity collision or high temperature. Once degaussed, the lock won’t open.
