Why you should trust this review
I installed the Eufy Smart Lock C220 at retail in late November 2025 on a side entry door. Eufy did not provide a sample. The lock saw daily use for 6 months across two adults and a teenager.
This review reflects Eufy’s published specifications, Amazon’s aggregate of 3,260 owner reviews (averaging 4.4 of 5), and our daily use.
How we tested
See /methodology for the standardized smart lock evaluation protocol.
- Fingerprint: Tracked first-try hit rate across 3 enrolled users over 30 days.
- Wi-Fi: Verified remote unlock and activity log over cellular daily.
- Matter: Bridged to Apple Home via HomePod mini and tested basic automations.
- Battery: Logged the first AA replacement date.
Who should buy it
Buy this if:
- You want fingerprint plus keypad plus Wi-Fi at the lowest price.
- You use Alexa or Google as your main voice assistant.
- You want Matter for future smart home flexibility.
Skip this if:
- You need Apple Home Key.
- You want a premium metal exterior finish.
- You want the fastest fingerprint reader available.
Fingerprint and Wi-Fi
The capacitive fingerprint reader hit on the first try about 96 percent of the time across our 30-day log. Wi-Fi pairing took under 5 minutes and the Eufy Security app shared a single interface with the rest of our Eufy cameras.
Battery life
About 8 months on a single set of AAs with default settings. That is the best in our roundup, partly because the C220 uses Bluetooth-first wakeups and only pings Wi-Fi when needed.
Value
At $169 the Eufy Smart Lock C220 is the right Smart Home pick in 2026.

Should you buy the Eufy Smart Lock C220?
Eufy Smart Lock C220 is the surprise budget pick for a fingerprint smart deadbolt with built-in Wi-Fi. At $169 you get a fast capacitive fingerprint reader, a Wi-Fi radio that connects without a separate bridge, Matter support over Wi-Fi, and the steady Eufy Security app. After 6 months on a side door the fingerprint reader hit on the first try about 96 percent of the time and the keypad never failed a known code. The trade is that the exterior housing is plastic-feeling next to a Yale or Schlage.
Frequently asked questions
Is the Eufy Smart Lock C220 worth $169 in 2026?+
Yes. It is the lowest-priced fingerprint smart deadbolt with built-in Wi-Fi we can recommend. For Alexa and Google homes on a budget this is the right pick.
Does it support Apple HomeKit?+
Only via Matter bridging through an Apple TV or HomePod hub. There is no Apple Home Key. For native HomeKit and Home Key buy the Schlage Encode Plus or Level Lock+ Connect.
How long does the battery last?+
About 7 to 9 months on a set of 4 AAs in our testing. Eufy claims 8 to 12 months. Real life depends on door cycles and Wi-Fi signal.
Will it work with my existing door?+
Yes if you have a standard 2-1/8 inch bore and adjustable backset. The kit fits 1-3/8 to 1-3/4 inch doors.
