Electronic locks do not pose a threat to mechanical locks


First, it is complicated: because the lock itself is a mechanical jamming mechanism, it is ultimately done by mechanical action. The electronic lock must complete the mechanical action (operation) - electronic conversion and electronic control - mechanical execution of this series of processes. Obviously it is more complicated.


Second, the probability of failure is relatively high: there are many electronic devices, and one is complicated. Inevitably increase the probability of failure, plus the electronic device is afraid of moisture, afraid of strong magnetic electricity, afraid of strong vibration, so that it has certain requirements for the use of the environment. Mechanical locks can easily avoid these weaknesses through a number of measures. If a TV set is broken, you don't have to send it for repair at the moment, but if the electronic lock is broken, you have to refuse to be outside the door. The repair can't be repaired, and you can't do anything about it. Many electronic locks have added an alternate unlocking method or emergency interface, which undoubtedly reduces security.


Third, the electronic lock must use electricity: the early electronic locks consumed more power, and generally used utility power. In 2013, the integrated circuit electronic lock consumes less power, and a button battery can maintain the control part, but the drive electromagnet or motor requires a larger battery or utility power. Some people have envisaged adding a manual power generation device to solve the problem of power consumption by itself, which makes the lock more complicated. In contrast, mechanical locks do not have to consider this issue. Although the electronic lock has the above problems, its large key amount and the advantage of not using the key are extremely tempting, attracting many inventors to work hard for this.
