Eufy Security Smart Lock C220 (Fingerprint) Review

What the Eufy C220 actually is

This is a deadbolt replacement that unlocks three ways: fingerprint, keypad code, or the old-fashioned physical key as backup. It sits at the cheaper end of the smart lock market, usually somewhere in the $120 to $170 range on Amazon, which puts it well under flagships from Schlage or August.

The headline feature is the fingerprint reader, and Eufy quotes unlock times under half a second. Owners broadly back that up. You touch the sensor, the bolt turns, you're inside. There's no waiting for an app or Bluetooth handshake, which is the whole point.

How it performs day to day

The fingerprint scanner is the star and it earns it. Recognition is fast and reliable for most users, and you can enroll multiple prints per person so a slightly-off thumb still works. For families, the keypad codes are the real workhorse. Hand the babysitter a temporary code, delete it later, done.

It runs on AA batteries rather than a rechargeable pack, which is either a plus or a minus depending on your patience for shopping. Battery life stretches for months, and there's a low-battery warning plus a USB-C jump-start option on the front if you get locked out with dead cells.

Here's the catch worth knowing before you buy. The base C220 is largely a standalone lock. It does not include built-in Wi-Fi, so remote control from your phone, away-from-home unlocking, and voice assistant tie-ins require Eufy's separate Wi-Fi Bridge or a HomeBase. If you assumed full app-everywhere control out of the box, that assumption will cost you extra.

The good and the not-so-good

On the plus side: genuinely quick fingerprint reads, three unlock methods, painless DIY install on a standard deadbolt, and a price that undercuts the big names. The keypad and physical key backups mean you're never truly locked out, which matters more than people think.

The downsides are mostly about expectations. No native Wi-Fi means smart-home features are a paid add-on. The plastic-heavy build feels its price, and it won't pass for a premium lock visually. Auto-lock and scheduling work fine but the app experience is functional rather than polished. And it's interior-mount only on a deadbolt, so it won't suit every door or apartment setup.

Who should buy it, and who shouldn't

Buy the C220 if you want to ditch your keys for fingerprint and code entry without spending flagship money. It's a strong pick for homeowners, families juggling kids and visitors, and anyone whose main goal is fast keyless entry rather than deep smart-home integration.

Skip it if remote phone unlocking and Alexa or Google control are must-haves and you don't want to buy a bridge. Renters with non-standard deadbolts should measure carefully first. And if you want a metal-clad lock that looks the part on a front door, spend up to a Schlage Encode or similar.

Verdict

The Eufy C220 nails the core job. Fast fingerprint unlocking, reliable codes, and a fair price make it an easy recommendation for keyless entry on a budget. Just go in knowing the smart features are optional extras, not included, and it punches exactly at its price point and not above it.

Frequently asked questions

Does the Eufy C220 work without Wi-Fi?

Yes. Fingerprint, keypad code, and physical key all work locally without any network. You only need Eufy's Wi-Fi Bridge or HomeBase if you want remote unlocking, notifications, or voice assistant control from your phone.

How long does the battery last on the C220?

It runs on AA batteries that typically last several months depending on use, and it gives a low-battery warning. There's also a USB-C port on the front for an emergency power boost if the batteries die while you're locked out.

Is the C220 fingerprint reader actually fast?

Yes. Eufy claims unlock in under half a second and owner reports generally agree. Enrolling more than one print per finger helps keep recognition consistent in cold or dry weather.
