Lock systems are mechanisms designed to secure doors, safes, and other entry points, preventing unauthorized access. They can be mechanical, using keys and tumblers, or electronic, utilizing keypads, cards, or biometric features like fingerprints. Each type offers varying levels of security and convenience. Modern lock systems often incorporate smart technology, allowing users to control access remotely through smartphones or other devices. This innovation enhances security by enabling features like temporary access codes and activity monitoring. Popular examples of smart locks include those from brands like August and Schlage, which provide both convenience and advanced security options.
