Abstract: In the contemporary world, where technology has advanced and with the incidents of thefts increasing, more traditional locking mechanisms such as a single lock and key are needed to offer better security. New, reliable, intelligent, and competent door-locking mechanisms are crucial for enhancing the security and safety of residential and commercial properties. This paper describes the design and implementation of an Arduino-based door lock system, which includes an LCD for displaying relevant information, a servo motor controlling the door’s locking mechanism, and a keypad for user input. The suggested method is password-protected, requiring the user to enter their password before accessing the door. When a user enters an erroneous password more than a predetermined number of times, the system also offers the option to reset the password and lock it out for a predetermined period. An additional feature of using the GSM module is to implement a function that notifies the owner of any unwanted access by sending a message to them when the door islocked afterthe number of incorrect passwords exceeds the set limit, thus alerting the owner to any unauthorised access. The suggested model’s incorporation of these elements enhances security. An online 3D design and simulation tool called Tinkercad is used to initially simulate the system. Thus, the suggested model of a password-enabled door-locking system enhances security and provides a solution that is easily adjustable and user-friendly by integrating hardware components and offering thorough simulation and testing through software simulation using Tinkercad software.
