eufy Security Smart Lock C210 T8502111 Black Keypad WiFi smart door lock

eufy C210 Smart Lock with Built-in Wi-Fi

The eufy Security Smart Lock C210 replaces a standard US deadbolt with a keyless entry system that connects directly to a home Wi-Fi network. No separate bridge is required for remote control through the eufy Security app. The lock supports five unlocking methods including keypad codes, physical key, Apple Watch, and voice commands via Alexa or Google Assistant. Installation takes roughly 15 minutes without drilling.

Best for Homeowners and Landlords Seeking Keyless

This lock suits anyone who wants to issue permanent or scheduled access codes for family, guests, or service providers and receive real-time entry notifications from anywhere. Renters or owners of non-standard doors should look elsewhere, as compatibility is limited to common US deadbolt preparations. Buyers needing HomeKit integration or a battery-powered design without hardwiring will not find those features here.

Built-in Wi-Fi Connectivity Decides Fit

The single specification that determines suitability is the integrated Wi-Fi radio, which enables remote locking, access management, and event history without an extra hub. If the entrance lacks reliable Wi-Fi coverage, the lock cannot deliver its core remote functions. Compatibility with existing deadbolt cutouts must also be verified before purchase.
