Digital advertisement is the current requirement of modern businesses and the information world. Security plays a major role where a Huge amount and expensive things are going to be stored (lockers, personal lockers, house purpose, etc…). The proposed system provides more benefits over a traditional lock, as well as great security. The KEY consists of a Fingerprint Sensor and 16x2 LCD along with a PICI8F452 microcontroller. The LOCK consists of a microcontroller along with a servo motor. Users can perform operations such as locking and unlocking the locker or door. The aim of this project is to make such type of lock which will provide more security as well as cost-efficient implementation. Electronic KEY consists of Fingerprint Sensor as input and LCD display as output device and microcontroller as controlling unit. The Fingerprint Sensor should provide to unlock the key which is set by the user. On the other option, Fingerprint Sensor changing option is gives more security, that only authorized persons can do it. Thus the security of this system is ensured.
