Abstract: Security has been playing a key role in many places, such as offices, institutions, libraries, and laboratories, to protect confidential data and prevent unauthorized access. At Isabela State University, traditional padlocks are still used to secure rooms, a method that lacks access logs and automation. To ensure data confidentiality and prevent unauthorized access, security technologies such as automated access, Short Message Service (SMS) alert, and light control are needed. The main objective of the study was to develop a security lock system and switching automation of devices that have features of storing fingerprints, operating the door lock, activating lights, and sending Short Message Service (SMS) notifications to the administrator based on stored fingerprints. The developmental research method, consisting of hardware and software development, was utilized in the study. Flowchart, block diagram, and wiring diagram were used to document the requirements, analysis, and design. In addition, the respondents’ perception of the system’s performance was gathered using a survey questionnaire, and total enumeration was employed in selecting the respondents. As a result, the device was perceived to be highly functional, usable, and reliable. Future researchers may integrate a database to store access logs and to send notifications not only to the building in charge but also to other heads of the institution. The system may also be expanded to facial recognition or two-factor authentication. These enhancements aim to make the system more reliable, scalable, and efficient for use in different environments.
