Smart Lock with Built-in Wi-Fi

The eufy Security T85D0 is a keyless entry deadbolt that connects directly to a home Wi-Fi network without a separate bridge. It suits homeowners who want remote control and access management through the eufy Security app. Physical keys, voice assistants and a physical button provide additional ways to unlock the door.

Sustained Operation and Auto-Lock Behaviour

The lock relies on mains power rather than a battery, so continuous Wi-Fi connectivity and auto-lock timing remain stable over long periods. Auto-lock engages automatically based on a user-defined schedule whether the door is open or closed. Physical buttons are designed for durability and error resistance during repeated daily use.

Compatibility Checks Before Ordering

Verify that the existing door preparation matches a standard deadbolt cut-out, as the unit is designed for 15-minute DIY installation with no drilling required. Confirm the home Wi-Fi network operates on a compatible band for initial setup and ongoing remote access. The package includes the deadbolt only.
