Keyed Alike Entry Door Knob and Deadbolt Set - Classic Matte Black

In this review of the keyed alike entry door knob and deadbolt combo, the bottom line is simple: it is aimed at homeowners who want a matching set of exterior locks that are easy to install and offer convenient single-key access to multiple doors. The set contains three keyed-alike knob and deadbolt pairs with three keys per set (nine keys total), and its strongest selling point is that one key opens all included locks, which removes the hassle of carrying multiple keys. It suits basic residential security needs and DIY installation.

Key Features

• All keys same: One key opens all three knob and deadbolt sets, simplifying key management for families and renters.
• Easy installation: Mounting screws, simple instructions, and a screwdriver are included so a competent DIYer can fit the locks quickly.
• Solid steel construction: The locks use solid steel components for a more durable feel compared with lighter materials.
• Adjustable backset: The latch adjusts between 2-3/8in and 2-3/4in to fit standard door configurations and common door thicknesses.
• Double security: Each set pairs a keyed exterior deadbolt with a thumb-turn inside for added protection on residential exterior doors.
• Matte black finish: A classic black appearance that matches many entry styles and hides fingerprints better than polished surfaces.

Who It's For

This set is best for homeowners, landlords, and small property owners who want three exterior-grade locks keyed alike for consistent access across multiple doors. The inclusion of three sets and nine keys makes it convenient for households, rental units, or small duplexes where the same key needs to open more than one entry.

It is less suitable for buyers seeking high-security commercial grade hardware or advanced anti-pick and bump protection beyond an ANSI Grade-3 standard. If you need heavy-duty commercial locks or electronic access control, look elsewhere.

Pros & Cons

Pros

• Easy installation with included hardware and instructions, good for DIYers.

• Solid steel build and matte black finish give a substantial look and resist obvious wear.

Cons
