What are digital locks? Electronic or Digital locks are electronic or battery-operated locks that do NOT require the use of physical keys for access. They're used as an alternative to conventional mechanical locks, with the automated features giving a more creative security solution depending on its intended use. Like any other door lock, digital locks also use a latch or bolt to secure the door to the doorframe in order to prevent access. The difference is how the latch or bolt is controlled. Digital locks work by the use of any of the following: RFID, Pin Codes, Fingerprints, Smartphones, and more.
