    FAQ

    Smart door locks can be worth it for their convenience and advanced security features. They offer keyless entry, remote access, and integration with smart home systems, which can enhance both security and ease of use. While they often come with a higher upfront cost, the added functionality and peace of mind they provide can make them a valuable investment.

    A smart lock uses electronic technology to control access to your door via Bluetooth or the Internet. You can unlock it remotely using a smartphone app, keypad, fingerprint sensor, or voice commands. The lock engages its mechanism electronically, and it employs encryption and secure protocols to protect against hacking.

    To install a smart entry door lock, follow these steps: 1. Gather the necessary tools like a screwdriver, measuring tape, and possibly a drill. 2. Unscrew and remove the old lock from your door. 3. Install the smart door lock assembly following the manufacturer's instructions. 4. Connect the video door locks to the door and frame. 5. Install batteries or power sources. 6. Configure the smart lock systems to your home's Wi-Fi network or hub, and set up any desired features or settings. 7. Test the smart lock.

    Smart locks can operate without Wi-Fi if they rely on Bluetooth or keypad entry for access. These options allow keyless convenience and secure control locally, without needing an internet connection. However, features like remote unlocking or live alerts typically require Wi-Fi. So, a smart lock without Wi-Fi still offers strong security, just with limited remote capabilities.

    Smart locks can automatically secure your door after a short delay. You can customize the auto lock timing anywhere between 30 seconds and 4 minutes. This feature reduces the chance of forgetting to lock up, giving added peace of mind without requiring any extra effort from you.

    Yes. Most smart locks have a mechanical key override, so they will still work in the event of a power outage. However, if the smart lock relies on batteries or Wi-Fi, you may lose some features if the battery is drained or Wi-Fi is disrupted but you can still open the door with the key.

    Yes, many smart door locks still have a key option. While smart door locks offer keyless entry using methods such as PIN codes, biometrics, or smartphone apps, most models also retain a traditional key cylinder as a backup or alternative entry method. This dual-functionality allows users to choose between keyless or key-based access depending on their preference or specific circumstances.

    Smart locks offer a different kind of protection compared to deadbolts. While they allow remote access and activity tracking, they can be targeted digitally. Deadbolts lack digital vulnerabilities but depend entirely on physical strength and correct usage. Both have their strengths, but choosing between them depends on the environment, your routine, and how you prioritize control versus mechanical simplicity.

    Smart locks are not inherently easier to bypass than traditional ones, but their security hinges on software. Poor encryption, outdated firmware, or weak passwords can leave them vulnerable. Well-designed smart locks with strong authentication protocols typically resist casual intrusions. So, security depends more on quality and maintenance than the concept of being “smart.”

    While smart door locks provide advanced security features beyond traditional locks, no system is completely impervious to hacking. To bolster the security of your smart door lock, select models like eufy smart locks that use bank-grade encryption. Additionally, use strong, unique passwords for your lock's settings and secure your home Wi-Fi network to further protect against unauthorized access.
