Smart Lock C30 with Built-in Wi-Fi

The eufy Security T85D0 is a keyless entry deadbolt for front doors 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, plus voice command support via Alexa or Google Assistant.

Battery-Free Mains Power and Auto-Lock

The lock draws power from the household supply so there are no batteries to replace or recharge. An auto-lock function secures the door automatically after a user-set interval whether the door is left open or closed, and physical buttons provide durable, error-resistant operation compared with touchscreen alternatives.

Standard Deadbolt Fit with 15-Minute DIY Install

Designed to replace most standard deadbolts, the unit measures 2.57 in by 1.63 in by 6.05 in and weighs 0.95 kilograms. Installation requires no drilling and takes roughly 15 minutes, freeing the existing key cylinder for backup entry while the app handles real-time notifications, event history and low-battery alerts.

Questions about this item

How do I install the T85D0 deadbolt on a standard door, and what step do people often miss?

The T85D0 fits most standard deadbolts with a 15-minute DIY installation that requires no drilling. The step people often miss is ensuring the deadbolt aligns perfectly with the strike plate before tightening the screws, otherwise the auto-lock may jam.

What maintenance will the T85D0 need over time?

The lock runs on batteries that will need periodic replacement; the eufy Security app provides low-battery alerts so you can swap them before the lock loses power.

What is the first limit I will hit if I use the T85D0 heavily every day?

The BHMA Grade 3 rating means the deadbolt is tested for residential duty cycles; under sustained high-traffic use the mechanical latch mechanism will reach its rated cycle life before the Wi-Fi or electronics do.
