eufy Smart Lock C220

Should you buy the eufy Smart Lock C220?

The eufy Smart Lock C220 is the under-$100 way to get a fingerprint deadbolt with Wi-Fi built in. At $109.99 it scores 80, thirty dollars less than the Ultraloq U-Bolt Pro WiFi, and it shares the same eufy Security app as the E340 doorbell, which makes it an easy add for anyone already in that ecosystem. Its weak spot is hardware grade. If you want a heavier-duty lock, spend the extra $30 on Ultraloq. If you want fast fingerprint entry at the lowest price in the category, start here.

Where it earns its score

• Value is the top factor at 92. The highest Value score of any lock or doorbell we track in this category. Nothing else gives you fingerprint plus Wi-Fi for under $100.
• Sub-second fingerprint. The self-learning reader gets faster as it sees your print more often, and there are six ways in: fingerprint, keypad, app, key, Apple Watch and voice.
• No bridge needed. Wi-Fi is built in and it lives in the same eufy Security app as the doorbells and cameras.
• Long battery life. Eight AA batteries last about eight months, longer than the Schlage Encode's six.

What to know first

• BHMA Grade 3. That is the lowest residential grade, and it is why Quality scores 66. The Ultraloq is ANSI Grade 1 and the Schlage is BHMA's top grade.
• Warranty is the weakest factor. One year from Anker/eufy versus lifetime mechanical coverage from Ultraloq and Schlage.
• IP53, not IP65. Fine under a covered porch, but it is less sealed than the Ultraloq if the door takes direct weather.
