Problems solved by technology

Traditional one-piece locks, due to the integrated design of the lock body, lock cylinder, and pin, have corresponding keys. Generally, if the key is lost or the key is duplicated, for safety reasons, limit the unlocking authority or The person who steals and duplicates the mechanical key (knows the password or has the corresponding mechanical key) to open the lock must replace it with a new one. A lock that is intact will become a useless lock just because one person knows the password or the key is stolen. Users cause unnecessary waste

This kind of situation happens frequently in the occasions where the unlocking personnel change frequently, such as rented houses and hotels. There is a certain waste and safety hazard in the use of the traditional integrated lock structure.
