eufy Security Smart Lock C30 — Keyless Front Door Deadbolt with Built-in Wi-Fi

Keyless entry meets simple, modern security

The eufy Security Smart Lock C30 brings keyless convenience to your front door with built-in Wi‑Fi, so you can manage access from anywhere using the eufy Security app. No bridge needed, and setup is designed to be straightforward for most homes.

With a physical key option and a sturdy keypad/button interface, you have reliable entry methods beyond a touchscreen. If you forget to lock up, auto-lock can secure the door automatically according to a schedule you set, adding peace of mind without extra steps.

Easy installation, strong reliability

The C30 is designed to fit most standard deadbolts and offers a 15‑minute do-it-yourself installation that avoids drilling. The system runs on 4 AA batteries (not included) and includes a low battery indicator so you know when to replace power before it matters. In typical use, the battery life can extend for months on a single set of cells.

In addition to remote operation, the lock accepts voice commands through Alexa or Google Assistant for hands-free convenience, while the wrong-try protection helps deter unauthorized attempts.
