Abstract: Modern Smart Door locks are highly prone to errors and damages making them less secure. Almost all Smart Door locks come with some passcode entry or fingerprint reader which resides outside the door making it vulnerable. This project aims at delivering the same security and reliability of a key lock mechanism making it retro and modern at the same time. As this Smart Lock operates on your phone’s fingerprint reader, you do not have to rely on something which is placed outside the door. First, the user has to pair his phone with the lock via Bluetooth and can only unlock when the devices are connected and successful fingerprint authentication occurs. Currently, the range of Bluetooth is around 50 meters ,but many times it is required that the devices should be more closer for security purposes. This project uses an algorithm for estimating distance between devices connected with Bluetooth so that the user can only unlock the door when he is close to it. Also in some cases it is required to unlock the door from a remote location. To perform this action we have connected the door lock to the network via WLAN, so that the user can unlock the door from his cell phone via mobile data.
