The term " master key " has been around for a long time. The "master key", as the name implies, is omnipotent, and it is easy to open the keys of various locks . In people's minds, a fixed look and shape has been formed. It is a key that does not have a "lock". In fact, the "master key" is a general term for many combination toggle tools made of steel wire, iron hooks and tooth molds. The principle of unlocking the "master key" is very simple. It uses steel wire, iron piece, tooth mold and many other plucking tools. It uses some very common mechanical mechanics and uses the clever force to move the lock cylinder to achieve non-destructive. The purpose of opening all kinds of locks without obvious traces. Under certain conditions, using the above tools to unlock, even faster and more convenient than the original key. Different locks have different mechanisms and structures. The unlocking tools used are different, and there is no very fixed mode. For a long time, in the contest between the "master key" and the lock, it is disappointing that the lock as a "shield" has been at a disadvantage for most of the time. With the rapid development of modern technology, the "master key" is constantly improving and upgrading. From the earliest primary unlocking tools (such as some small steel wire, small iron pieces, etc.), it has rapidly developed to the more advanced high-pressure expansion airbags, high-frequency vibration brushes and electric electromagnetic unlockers; more advanced is superconducting soft -ray detection. Instruments, ultrasonic high-frequency detectors and the latest laser scanners use a variety of light waves, ray scanning and detection of the internal structure of the lock and easy to open. At the same time, due to various computer electronic locks, password locks , fingerprint locks and retina electronic locks, a series of locks using high-tech electronic technology, the intelligent decoder for this type of locks, the electronic code breaker is also rapid Appeared. The "master key" is also very conforming to the "trend of the times" and gradually develops into a highly intelligent and foolish way. The earliest and simplest iron hooks, steel sheets, etc. can be mastered with only a short practice; today's high-intelligence unlockers do not require any technology or skill at all, and only need to be energized to generate high-frequency vibration. It is more convenient and quick to unlock at will.
