You can grant temporary access to guests or service providers, eliminate the need for physical keys, and even monitor access logs from your phone.
Q2: How do interior smart locks typically get power?
A2: Most interior door smart locks are battery-powered, typically using AA or AAA batteries.

A6: Key considerations include the unlocking methods (fingerprint, keypad, app, key fob, mechanical key), battery type (rechargeable vs. disposable) and life, ease of installation, app features (access logs, temporary codes), privacy (local vs. cloud data storage), and whether you need remote Wi-Fi access (which often requires an additional gateway).
Q7: Can I use an interior door smart lock for an Airbnb or rental property?
