What are "smart locks" known for?

Smart locks are recognized for offering advanced features that enhance security and convenience, such as mobile app control and remote access capabilities. This technology allows users to lock or unlock their doors from anywhere using a smartphone or tablet, providing significant flexibility compared to traditional locking mechanisms. Additionally, smart locks can integrate with home automation systems and provide features like real-time monitoring, temporary access codes for guests, and alerts if the lock is tampered with.

The alternative options highlight characteristics that do not align with the defining features of smart locks. Providing physical keys for all users contradicts the smart lock's purpose of enhancing access management through electronic means. Being solely mechanical disregards the technological advancements and functionalities that smart locks offer. Lastly, while battery lifespan can vary among smart locks, focusing on this aspect does not capture the essence of what makes smart locks distinctive in the realm of access control.
