eufy Security T85L0 Smart Lock with Fingerprint Entry, Wi-Fi & Nickel Finish

Fingerprint entry gives this smart lock a convenient way to open the door without reaching for a key, while built-in Wi-Fi adds app-based control for managing access remotely. The eufy Security T85L0 combines a handle with an electronic deadbolt in a nickel-finish metal design for residential or commercial use.

For a door used mainly for quick everyday entry, fingerprint access keeps the interaction simple. If remote access management matters more, the Wi-Fi connection adds app controls, notifications, and event history.

Highlights

The lock supports fingerprint recognition, passcodes, the eufy app, NFC, voice control, and a physical key, giving household members more than one way to enter. It stores up to 50 fingerprints and 100 passcodes, so access can be set up for multiple people. Auto-lock adds a useful step to a routine: after entering or leaving, the door can lock automatically according to its countdown setting.

With built-in Wi-Fi, the app provides remote control along with access management, real-time notifications, and an event history. The lock also works with eufy video doorbells and security cameras, making it a practical part of a home security setup. Its exterior assembly is rated IP53, and the nickel finish gives the handle and deadbolt a coordinated look.

Buyer feedback is varied. Customers often praise the fingerprint reader’s response and Wi-Fi connection, while reports about ease of use and reliability are mixed. Some also raise concerns about battery use and durability, including reports of replacing the 8 AA batteries every 2–3 months. The lock’s stated power source is 8 AA batteries.

Size & fit

The lock measures 7.24 x 6.06 x 5.12 inches and weighs 1.91 kg. Its metal construction and nickel finish suit buyers looking for a contemporary handle-and-deadbolt design rather than a separate keypad-only device. The set is intended for a single door lock installation, with left- and right-hand doors supported. The product information describes installation as requiring no drilling and taking about 15 minutes.

Best use cases

For a busy household, fingerprint entry can make frequent trips through the front door easier, while stored fingerprints and passcodes provide different access methods for family members. For a side, garage, office, or basement door, app controls and access notifications can help the owner manage entry without relying only on a traditional key. The physical key is also available as an alternative entry method.

This model is a better fit for shoppers seeking biometric access and connected controls in one handle-and-deadbolt unit than for those who only want a conventional mechanical lock. Its capacity for fingerprints and passcodes is especially useful when several people need individual access, and auto-lock supports a more consistent locking routine.

Is it worth it?

It makes sense if you want to combine fingerprint or passcode entry with remote app control and automatic locking. The T85L0 brings those features together with built-in Wi-Fi, a physical-key option, and compatibility with eufy video doorbells and security cameras. For a front, side, office, or other frequently used door, it offers flexible entry methods and app-based access management in a nickel-finish lock with handle.
