Probrico Door Knobs with Same Key 8 Pack - Keyed Entry Ball Knob

In this review of the Probrico Door Locks Knobs 8-pack, the bottom line is straightforward: this set is aimed at homeowners or small property managers who need multiple keyed entry knobs that match and install quickly. The most compelling reason to buy is the same-key convenience across all eight locks, which simplifies key management for several exterior or interior doors. Installation is simple and the metal construction feels substantial enough for everyday use, making it a practical choice when consistent keyed access and affordability matter.

Key Features

• Same key convenience: All eight locks are keyed alike so one key opens every lock, saving time and eliminating multiple keys for the same property.
• Adjustable backset: The latch accepts 2-3/8 in or 2-3/4 in backset, so the knobs work on most standard doors without swapping parts.
• Door thickness compatibility: Fits doors 1-3/8 in to 1-3/4 in thick, covering common residential interior and exterior door sizes.
• Solid Column security bolt: The reinforced bolt provides anti-sawing protection to improve resistance against forced entry compared with basic latches.
• ANSI Grade 3 compliance: Conformed with ANSI Grade 3 security standards, offering a baseline level of durability and safety for home use.
• All accessories included: Easy installation is supported by included hardware so a homeowner can typically install each knob with common tools.

Who It's For

These knobs are best for budget-conscious homeowners, landlords, or renovators who need multiple keyed entry points that use the same key - for example a main door plus storage or utility doors, or multi-unit properties where consistent access is helpful. The set works well where moderate security and uniform appearance are priorities.

Those who need high-security commercial hardware, heavy-duty tamper resistance, or a decorative designer finish should look elsewhere; while the metal construction is solid for residential use, this product is positioned as a practical, value-oriented lockset rather than premium hardware.

Pros & Cons

Pros

• Same-keying across eight locks streamlines access and reduces key clutter.
• Easy installation with included accessories makes fitting the knobs a straightforward DIY job.
• Adjustable backset and wide door thickness compatibility mean this set suits most standard doors.
• Solid Column security bolt and ANSI Grade 3 conformance add reasonable security for home use.

Cons

• Some users report mixed impressions of build feel, so it may not match the heft of higher-end locksets.
• The latch square plate is unremovable, which limits latch orientation options in a few retrofit situations.
