Protecting lives, pioneering technology - JEI Pioneers in electric locks and security devices JEI (Japan Electronic Industry) was established in 1962 as Japan's first domestic electric lock manufacturer. For over half a century, we have chronicled the history of disaster prevention and crime prevention devices and access control systems in Japan, based on the philosophy of respecting human life. The electric lock "Free Lock" has been certified for disaster prevention performance by the former Ministry of Construction [(Public Interest Incorporated Foundation) Japan Architecture Center]. The electric lock control panel CB series is compatible with most electric locks from various manufacturers. Equipped with disaster prevention and crime prevention functions, we play a key role in access control management in various scenarios through optimal control of various security terminal devices.
