Home burglaries and theft activities are increasing steadily these day. Not only that, the school kids and university students are also facing the same issues of losing their valuable items in the classrooms and residential rooms. With modernization of home automation system with the concept of safe locking and alert system, it helps in managing and reducing burglaries and theft activities. However, these concepts are still costly to be implemented in classrooms in the schools and residential rooms in the universities. This paper discusses on the alternative and cheaper solution using Bluetooth technology in assisting the students for safe keeping of their valuable items. This first prototype of the locking systems is developed for drawers and android based mobile phones using Arduino UNO and Android Studio. The prototype is successful developed, and user acceptance testing is carried out. The findings proposed for future enhancements of the prototype before the locking systems can be fully implemented and utilized by the university's residential rooms. © 2017 IEEE.
