Q1: Why should I put a smart lock on an interior door?
A: Smart locks on interior doors offer enhanced privacy for bedrooms, home offices, or storage areas. They provide keyless convenience, allowing you to enter with a fingerprint or code, and make it easy to grant temporary access to family, friends, or even cleaners without sharing physical keys.
Q2: Are smart locks for interior doors secure?
A: Yes, they are designed to provide a good level of security and privacy for internal use. While not as robust as exterior deadbolts, many feature biometric access (fingerprint), keypads, and even app controls, which can be more secure than traditional keyed locks that can be picked or duplicated.
Q3: How do I install a smart lock on my interior door?

Q4: Do interior smart locks need Wi-Fi to work?
A: Many interior smart locks, especially fingerprint door knobs, primarily use Bluetooth for app control within a close range. While they function perfectly without Wi-Fi for basic unlocking, some models might require a separately purchased Wi-Fi gateway to enable remote access features (like unlocking from anywhere or receiving notifications when you’re away).

Q6: Can I grant temporary access to a guest or service person?
A: Absolutely! This is one of the main benefits. Many smart locks allow you to create temporary passwords or grant time-limited access through their companion apps. This is ideal for Airbnb hosts, guest rooms, or when you have someone coming to water your plants while you’re away.

A: Yes, they are often perfect for apartments, individual rooms in shared housing, or rental properties like Airbnbs. They offer an easy way to manage access for multiple tenants or guests without the hassle of key exchanges.
