Buying Guide: What to Look for in a Smart Lock
When shopping for a smart lock, it pays to know what features matter most. Below we break down the key criteria to consider.
Connectivity: WiFi Built-in vs. Hub Required
Some smart locks connect directly to your home WiFi, while others need a separate hub or bridge. A built-in WiFi lock is easier to set up and lets you control the lock from anywhere using an app. If you want to integrate with other smart home devices, check for compatibility with Alexa or Google Assistant.

All three locks we reviewed feature built-in WiFi, so you can skip the extra hardware. The Philips model even works with a 2.4GHz network without a hub, making setup a breeze.
Security and Durability: Grades and Certifications
Look for locks that have been certified by the Builders Hardware Manufacturers Association (BHMA). A higher grade means better durability and resistance to tampering. The Yale lock, for example, is Grade 2 certified, while the eufy model is Grade 3. Both provide reliable security for a typical home. If you want a lock that can withstand extreme temperatures, check the operating range. The eufy C220 works from -22°F to 158°F, making it suitable for many climates.
Ease of Installation and Use
Most smart locks install in about 15 minutes using just a screwdriver. They fit standard deadbolts, so you can replace your existing lock without drilling new holes. The Philips and eufy models come with handles, while the Yale lock includes a keypad and backup key. For a lock that works well with Apple HomeKit, visit our best smart lock with Apple HomeKit page.
Consider how many ways you can unlock the door. Fingerprint sensors, keypads, app control, and voice commands all add convenience. The Philips lock offers 0.3-second fingerprint access, while the eufy lock uses self-learning AI to improve fingerprint recognition over time.
