Nowadays technology is being found in each and every part of our life. By using these emerging technologies we can overcome the problems with conventional lock systems. So we are proposing a keyless system, in which the password is being sent from Bluetooth to microcontroller to access the door. For the security of password AES(Advanced Encryption Standard)algorithm is being implemented. In this system multilevel protection is also being provided through password reconfiguration option. In case of emergency the door can be accessed through fingerprint module. This form of locks will provide an inexpensive solution for the security of door locks by integrating Android and Microcontroller module.
