Black Entry Door Knobs Keyed Alike 6-Pack - Reversible Leverset Combo

In this review of the Probrico (6 Pack) Black Entry Knobs, the bottom line is simple: this set is aimed at homeowners, landlords, and small businesses that need multiple matching locks with a clean look and straightforward installation. The single biggest reason to buy is the keyed-alike convenience combined with a sturdy zinc alloy lever in an elegant black finish, which gives a cohesive appearance across several doors while remaining corrosion resistant. The review focuses on real use: fit for standard doors, easy swap of left/right levers, and quick DIY setup.

Key Features

• Keyed Alike: Multiple locks come with the same key so you can open several doors with one set of keys, useful for tenants or rooms that should share access.
• Elegant Wave Design: The wave style lever is made of durable zinc alloy and provides a comfortable grip while adding a modern, understated look to interiors and exteriors.
• Black Corrosion-Resistant Finish: The black surface resists fading and corrosion, helping the levers hold their appearance over time in normal home and office environments.
• Reversible Levers: The levers can be configured for left or right handed doors by swapping the interior and exterior pieces, so one SKU fits varied door setups.
• Adjustable Latch and Standard Fit: The latch is adjustable to 60mm or 70mm (2-3/8 in or 2-3/4 in) and fits door thicknesses from 35mm to 45mm (1-3/8 in to 1-3/4 in), covering most standard residential doors.
• Quick Installation: All accessories and an instruction template are included so a single person with a screwdriver can install the set in minutes.

Who It's For

This 6-pack is ideal for landlords outfitting several rental doors, homeowners replacing multiple interior and exterior knobs for a uniform look, and small offices that prefer one key for many rooms. The keyed-alike feature and included hardware make it a practical choice when consistency and simple maintenance are priorities.

It is less suitable for high-security applications where advanced cylinder security or heavy-duty commercial rating is required, or for doors outside those that exceed the listed thickness or require a removable square latch plate. For those use cases, a commercial grade or heavy-duty lockset would be a better choice.

Pros & Cons

Pros

• Good value for a six-pack of matching keyed locks that simplify access management.
• Attractive, ergonomic wave lever in a black finish that looks more expensive than the price suggests.
• Easy to install and reversible for both left and right handed doors, cutting down on part variants.
• Fits common door thicknesses and has adjustable latch options for typical residential use.

Cons

• Some buyers noted mixed experiences around long-term breakability or lockability, so it may not match premium security cylinders.
• The square plate on the latch is not removable, which could complicate installation on some older or nonstandard door frames.
