Keyless Entry with Built-in WiFi

The eufy Security Smart Lock C30 is a Wi-Fi connected deadbolt that replaces a standard cylinder without extra hubs. It supports app control, voice assistants and up to 100 unique passcodes. Installation takes about 15 minutes using the supplied deadbolt and fits most standard door preparations. Power comes from batteries that are not included in the box.

100 Passcodes for Access Management

The lock stores up to 100 different passcodes, allowing household members, guests or service providers to enter without physical keys. Each code can be created or revoked remotely through the eufy Security app, and the lock auto-locks after a user-defined interval whether the door is open or closed.

Suits Homes Needing Remote Access Without a Bridge

This model suits owners who want smartphone control and voice integration with Alexa, Google Assistant or Apple HomeKit without buying a separate bridge. It is not suited for doors with rounded latch holes, for buyers who need Matter or IFTTT compatibility, or for anyone expecting batteries to be supplied.

Questions about this item

How many different passcodes can the lock store?

The lock stores up to 100 unique passcodes, letting you give family, guests or service people their own code and delete it later without re-keying the cylinder.

What does the built-in Wi-Fi actually let me do without a separate bridge?

You can lock or unlock the door, check status, receive real-time alerts and view event history from anywhere using the eufy Security app on your phone.

Will the deadbolt fit my existing door without drilling new holes?

It fits most standard deadbolt cut-outs and installs in about 15 minutes with just a screwdriver, but it will not work with a rounded latch hole.
