eufy Security Smart Lock C220 fingerprint Wi-Fi smart door lock

Fingerprint door lock for keyless entry

The eufy Security Smart Lock C220 replaces a traditional deadbolt with a fingerprint reader that recognises a finger in less than .3 seconds. It connects directly to the home Wi-Fi network so no separate bridge is required. The lock fits most standard US and Canadian deadbolt cutouts and is rated IP53 for weather resistance. Six unlock methods include fingerprint, keypad, physical key, the eufy Security app, Apple Watch and voice assistants.

Black finish with rechargeable battery lasting

The unit measures 7.67 by 4.49 by 4.41 inches and weighs 3.1 lb. Eight AA cells power the lock for roughly eight months depending on usage frequency. Built-in Wi-Fi enables remote control, access management, real-time notifications and event history from anywhere through the app. BHMA testing indicates a lifespan equivalent to ten operations a day for over thirty years. Anti-peep passcode protection lets users add random digits before or after the real code.

Upgrades a mechanical deadbolt when remote access

Buyers who need to grant temporary codes to guests or service people from a phone will benefit from the Wi-Fi connectivity and app-based user management. The self-learning fingerprint algorithm improves recognition accuracy over time, reducing failed attempts. Households without an existing smart-home hub avoid the extra cost and complexity of a bridge. Those who prefer a purely mechanical lock or require a mortise-style installation will not find this model suitable.
