Probrico Round Ball Front Door Knob and Deadbolt Combo Set - Keyed

In this review of the Probrico 6 pack round ball front door knob and single cylinder deadbolt combo sets, the bottom line is straightforward: this kit is best for property owners who need consistent keys across multiple exterior doors and a simple, classic look at a modest price. Installation is generally easy, and the keyed alike feature removes the nuisance of managing many different keys. The set aims at value and straightforward function rather than premium heavy-duty security, making it a practical pick for rental units, interior exterior doors that do not face high-risk exposures, or homeowners who need multiple matching locks.

Key Features

• Single Cylinder Deadbolt: The deadbolt locks with a key from the outside and a thumb-turn from the inside for quick egress and familiar operation.
• Identical Keys: All lock sets in the multi pack come keyed alike so one key opens every deadbolt and knob, simplifying access for property managers or busy households.
• Wide Application: The round ball knob has a traditional yet versatile look that suits transitional, Victorian, colonial, and contemporary interiors and rentals.
• Adjustable Backset: The stainless steel latch adjusts between 2-3/8 in and 2-3/4 in so the set fits standard door preparations without extra drilling.
• Door Thickness Compatibility: Fits doors from 1-3/8 in to 1-3/4 in, covering the most common residential door sizes for easy replacement.
• Durability Tested: The hardware exceeds 200,000 cycles with ANSI Grade 3 verification, indicating reliable mechanical life for typical use.

Who It's For

This combo set is ideal for landlords, owners of multi-door properties, and homeowners who want uniform keys across several exterior doors to reduce key clutter and simplify access. It also works well for those replacing basic entry hardware who favor a classic round knob in an oil rubbed bronze finish.

It is not aimed at buyers who need top-tier security hardware for high-risk entrances or commercial-grade heavy use; customers seeking highest-security deadbolts or premium solid-metal trim should look at higher grade lock sets instead.

Pros & Cons

Pros

• Keyed alike convenience makes daily access and management much easier for multi-door properties.

Cons

• Some buyers report mixed perceptions of build quality and have concerns about lock security compared with higher grade options.
• Not designed for high-security or commercial applications where reinforced hardware is required.
