Frequently Asked Questions (FAQ)
Q1: What is a smart lock and how does it improve home security?
A1: A smart lock is an electronic-mechanical lock that can be controlled wirelessly and allows for keyless entry into your home or business. It improves security by offering features like remote monitoring, temporary access codes, biometric entry (fingerprint, face ID), and integration with smart home systems, giving you more control and visibility over who enters your property.
Q2: Do I need Wi-Fi for a smart lock to work?
A2: Not all smart locks require Wi-Fi. Some operate purely via Bluetooth for app control within proximity, or rely on keypad/fingerprint entry. However, if you want remote access features like locking/unlocking from anywhere, receiving real-time alerts, or integrating with voice assistants, a Wi-Fi connection (often via a built-in module or a separate gateway/hub) is typically required.
Q3: How easy is it to install these smart locks?
A3: Most modern smart locks, including the ones reviewed here, are designed for DIY installation and can be set up in 10-20 minutes with just a screwdriver. They are generally made to replace standard deadbolts or existing door knobs without requiring professional help or additional drilling.
Q4: What happens if the smart lock’s battery dies?
A4: All quality smart locks include a low battery warning. If the battery does die, they typically come with a backup solution, most commonly a traditional mechanical key override or a USB port for emergency power (e.g., via a power bank) to get you in the door.
Q5: Are smart locks like a Kaadas smart lock compatible with all door types?
A5: Most smart locks are designed to fit standard US residential doors. Key specifications to check include door thickness (usually 1 3/8″ to 2″ or 35mm to 50mm) and backset dimensions (the distance from the door’s edge to the center of the bore hole, usually 2 3/8″ or 2 3/4″). Always consult the product’s specifications to ensure compatibility with your specific door.
Q6: Can I grant temporary access to guests or service providers?
A6: Yes, a major advantage of smart locks is the ability to generate temporary or one-time access codes, eKeys, or even schedule access for specific times and dates. This feature is incredibly convenient for house sitters, cleaners, delivery services, or short-term rental guests, removing the need to hand out physical keys.
Q7: How secure are smart locks against hacking or forced entry?
A7: High-quality smart locks are built with multiple layers of security. Electronically, they use strong encryption protocols to prevent unauthorized access. Physically, many meet or exceed ANSI Grade 1 or Grade 2 security standards, meaning they are highly resistant to forced entry, picking, and drilling. Features like wrong-try protection and anomaly alarms further enhance their security against tampering.
