Mortise Keyed Lock Set with Classic Knobs - Vintage Replacement Kit

Our review of this mortise keyed lock set finds it best suited for homeowners restoring period interiors or replacing a broken antique door knob set. The single biggest reason to buy is the authentic vintage look combined with a practical mortise lock mechanism that fits standard interior doors; the oil rubbed bronze finish and skeleton-key styling deliver the period aesthetic while the kit includes the mortise assembly and all mounting hardware for a straightforward swap. For the right door this is a sensible balance of appearance and value.

Key Features

• Antique replacement: Designed specifically to replace old-style handlesets with a mortise lock and skeleton key look, restoring period character to interior doors.
• Fit range: Fits 1-3/8 in to 1-3/4 in thick interior doors with a standard 2-3/8 in backset, covering most bedroom and bathroom doors.
• Vintage finish: Oil rubbed bronze plated steel trim plates and vintage steel knobs provide an authentic, aged appearance that suits traditional decor.
• Non-handed installation: The mortise lock can be used on left or right handed doors by flipping the locking tab, simplifying replacement on different doors.
• Complete kit: Includes 2-1/4 in knobs, escutcheon plates, faceplates, mounting hardware, installation template and instructions to reduce guesswork during installation.

Who It's For

This kit is ideal for DIYers, homeowners renovating older houses, and anyone who needs a like-for-like replacement for a broken antique mortise lockset on interior doors. The included template and instructions make it accessible to a competent DIYer with basic tools.

It is less appropriate for exterior doors, nonstandard backsets, or very thin or thick custom doors outside the 1-3/8 in to 1-3/4 in range. Buyers who need high-security modern deadbolts or electronic locks should look elsewhere.
