Smart locks have created a new home security experience with customization features and functionality designed to give you control over what happens to your home. Here's a look at what smart locks can do and how they work. Smart locks are a relatively new and evolving technology. Some rely on fingerprint scanning, while others utilize digital assistant support and mobile apps. Evaluate a smart lock's features and functionality and choose the best one for your needs. What Can a Smart Lock Do? Smart locks go way beyond the capabilities of ordinary locks. Many come with both Bluetooth and Wi-Fi connectivity, which increases the ability to use remote features. If a smart lock had only Bluetooth connectivity, you'd have connection problems if your front door was too far from your smart home hub. Here are some important smart lock features to look for: App Support Most smart home locks have iOS and Android apps that allow you to control the lock remotely from your mobile device, monitor comings and goings, and alert you to any activity. Wi-Fi Connectivity Wi-Fi connectivity lets you view entry and exit logs in real-time, so you always know who has come and left your home, and when. This is an important feature for parents who want to make sure their kids have arrived home safely from school. Bluetooth Connectivity Bluetooth connectivity helps your smart lock recognize you by connecting with your smartphone and unlocking your door as you approach.

Limitations can include days of the week and specific hours to ensure code holders can access your home only during approved times.

Common Concerns About Smart Locks When it comes to the security of your home and family, it's natural to have concerns about making the switch to a smart lock. Here are some common concerns many people have about smart locks: Can a hacker use the smart lock's Wi-Fi connection to access my home? Keep your connected smart home devices secure from hackers and electronic tampering by setting up your Wi-Fi system using security best practices. For example, require a password to connect to your Wi-Fi, and always use complex passwords. Since your smart lock and all your connected smart home devices access the internet through the same Wi-Fi setup as your computers, smartphones, tablets, and TV streaming services, a secure Wi-Fi setup is critical. How much do smart locks cost? Depending on the brand, model, and features, a Wi-Fi-enabled smart lock can cost anywhere from $100 to $300. If my internet connection or electricity goes out, how do I get into my home? Many smart lock models also come with a traditional key port so you can use it as a standard lock if needed. Additionally, Bluetooth connectivity will still work with your smartphone when you're in range for the phone and lock to connect. Smart lock manufacturers are aware of these types of issues, and many have their own solutions for these situations.
