Lock History – Electronic Locks

Latest Development

Electronic lock is the latest development in the History of Locks. An electronic lock is a locking device which operates by means of electric current. Electronic locks are sometimes stand-alone, more often connected to an access control system. The advantages of an access control system include: user management, log-in registry and time control.

Electronic Locks

Electronic locks use password, card or biometric recognition to activate the electronic system that will trigger the mechanism. Operating the lock can be as simple as using a switch, for example an apartment intercom door release, or as complex as a biometric based access control system.

Numerical codes

Perhaps the most prevalent form of electronic lock is that using a numerical code for authentication; the correct code must be entered in order for the lock to deactivate. Such locks typically provide a keypad, and some features as an audible response. Combination lengths are usually between 4 and 6 digits long.

Smart Card

Another means of authenticating users is to require them to scan or “swipe” a security token such as a smart card or similar.


As biometrics become more and more prominent as a recognized means of identification, their use in security systems increases. Some new electronic locks take advantage of technologies such as fingerprint scanning, retinal scanning and iris scanning, and voiceprint identification to authenticate users.


Radio-frequency identification (RFID) is the use of an object (typically referred to as an RFID tag) applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader. This technology is also used in modern electronic locks.
