Abstract—Nowadays we required security from stranger. Hence we can design this type of door lock. In this Venture lets learn howto construct a Watchword based entryway bolt framework by meddle Arduino enter the password using the 4×4 keypad.We moreover interface an LCD show to form enter the password and change the password without encoding Arduino Once more. We are employing a Solenoid bolt which locks and opens the entryways by entering the secret word through the keypad and LCD show is utilized to Send events and messages.With this Extend ready to construct a security framework which works with secret word. In this Project we are building a security framework which works with watchword. But by increment in innovation, modern sort of locks such as electronic locks, savvy locks were concocted and individuals are utilizing them broadly to secure their resources. So, lets utilize the highlights Arduino micro control keyboard to function the Solenoid lock utilizing watchword. You'll coordinated this extend with indeed lockers
