Most of the people, nowadays, are purchasing and using the different types of locks designed, manufactured and marketed as devices that can promote safety and protection and can help in preventing these common crimes from occurring. A lock is basically described as a fastening device that can be freed or released with a physical object like a fingerprint, RFID or radio-frequency identification card, security token, key, and keycard; a combination provided by the manufacturer or the owner; and with a secret information such as a keyword or password being supplied by the owner.

The four examples of the locks with electronic keys are the keycard lock, which can be operated with the use of flat card like a driver’s license and credit card; the smart lock, which is recognized as an electromechanical lock that can open or close the door with the use of an authorized device through a wireless protocol and cryptographic key; the sidebar lock, which can operate through the use of fins on a radial key that can activate the sidebars by aligning a cylindrical code bar found within the lock; and the electronic lock, which is connected to an access control system and can operate via an electronic current.
