Buying Guide for the Best By Smart Locks
Choosing a smart lock is all about finding the right balance between convenience, security, compatibility, and features that matter most to you. Think about your daily habits: Do you want to unlock with your phone, a code, or a key? How often do guests need access to your home? Will the lock be exposed to weather? Reflect on your lifestyle and the devices you already use at home, since a good smart lock should fit seamlessly into your routine and home ecosystem.Lock TypeLock type refers to how the smart lock is installed and what parts of your existing lock it changes or replaces. The main categories are retrofit (which modify your current deadbolt and let you keep your original keys) and full replacement (which replace the entire lock and may give you new keys or none at all). Retrofit options are great if you want an easier, less intrusive install or keep backup keys, while full replacements may offer more modern features and looks. Think about how much you want to change your door and whether you need to retain physical keys.
Unlocking MethodsUnlocking methods describe how you open the lock—common options include keypads (entering a code), smartphone apps, fingerprint sensors, voice assistant integration, or traditional keys. Some locks have multiple methods for flexibility. Keypads and apps are very popular for easy sharing and remote access; fingerprint sensors are super quick but can be less reliable in extreme temperatures; voice control is convenient but needs a smart speaker. Consider who needs access, how tech-comfortable they are, and if you want entry without your phone or keys.
ConnectivityConnectivity determines how your smart lock talks to your phone or home network, using standards like Bluetooth, Wi-Fi, Zigbee, or Z-Wave. Bluetooth is simple and works without internet but mostly when you're close by; Wi-Fi gives you anywhere-access and remote notifications but often needs more power (frequent battery changes); Zigbee/Z-Wave are for those with smart home hubs, offering advanced integration. Choose based on whether you want to control your lock remotely, need frequent notifications, or have a larger smart home setup.
Power SourceSmart locks usually run on batteries (like AA or rechargeable packs), and some have emergency key or USB backup. Battery life varies—basic Bluetooth locks last longer, while Wi-Fi locks drain faster. Think about how often you want to change batteries, and look out for low-battery alerts. If you want minimal maintenance, both battery life and backup options should be a focus, especially for doors that get a lot of use.
Security FeaturesThis spec covers added protections like auto-locking, tamper alarms, two-factor authentication, or encryption. Auto-locking is useful if you often forget to lock up. Tamper alarms can alert you to forced entry. Two-factor authentication (2FA) and strong encryption keep your data safe from hackers. Decide which features give you peace of mind based on your area, home traffic, and your comfort level with using app-based controls.
CompatibilityCompatibility refers to two areas: whether the lock fits your door, and whether it works with your other smart devices (like Amazon Alexa, Google Home, Apple HomeKit, or SmartThings). Check your door’s thickness and lock style—you may need a specific fit. For smart home users, make sure the lock integrates smoothly with your current (or future) system so everything works together with minimal hassle.
Access ManagementAccess management describes how easily you can add, remove, or customize who gets in—like temporary codes for guests, scheduled access for cleaners, or tracking entry/exit logs. Cloud-based locks usually offer more flexible options through their apps. Decide how much control you want over sharing access and reviewing entry logs, especially if you host guests or want to monitor arrivals and departures.
Weather ResistanceWeather resistance is crucial if your lock faces the outdoors. Look for locks rated for waterproofing and temperature extremes. If you live in an area with harsh climates—lots of rain, frost, or high heat—make sure the smart lock is designed for outdoor use to avoid malfunctions and prolong its life.
