One-Piece Lockset Replacement

The Nyboer H3B smart door lock in black replaces the entire front-door lockset in a single unit. Its 9.25-inch extended panel covers both deadbolt and handle holes without patching or exposed gaps. Installation is designed for DIY fitting on standard single-hole or double-hole doors. The lock provides a clean, finished appearance once mounted.

Suits Homeowners and Rental Managers

This lock works for anyone who wants keyless entry via fingerprint, keypad, app, key fob or mechanical key. Remote locking, scheduled codes and activity logs are managed through the mobile app. Buyers who need remote or voice control without adding a Wi-Fi gateway should look elsewhere. Properties that require a mortise or multi-point locking system are not compatible.

9.25-Inch Extended Coverage Panel

The extra-long 9.25-inch panel is the single specification that determines fit. It fully conceals existing deadbolt and handle cut-outs on standard U.S. exterior doors. If the door prep spacing or thickness falls outside the 9.13 x 3.13 x 1 inch backset dimensions, the panel will not cover the holes.

Questions about this item

How much power does the 9.25 inch lock draw when running all day?

The lock runs on four AA batteries; typical use gives several months before replacement.

What existing door hardware must I already have for the 9.13 by 3.13 inch unit to fit?

Fits standard US doors with 2-3/8 or 2-3/4 inch backset and 1-3/8 to 1-3/4 inch thickness.

Will the 30 day return window cover testing with my old mechanical key cylinder?

Yes, the mechanical key override works with the supplied cylinder; your old key will not operate this lock.
