Probrico Flat Black Entry Door Knobs and Deadbolt Combo Set - Keyed

In this review of the Probrico flat black entry door knobs and single cylinder deadbolt combo set, the bottom line is simple: this set is for someone who needs a coordinated, keyed-alike exterior lock solution that looks contemporary without paying premium hardware prices. The set's biggest selling point is the keyed-alike option that lets up to a dozen locksets share the same key, which is especially useful for rental properties, multi-door homes, or anyone who dislikes carrying multiple keys. Installation is generally straightforward for standard doors, and the matte finish gives a clean, modern look.

Key Features

• Single cylinder deadbolt: The deadbolt locks and opens with a key outside and a thumb-turn inside, offering familiar, simple operation for exterior and interior doors.
• Keyed alike option: When ordering multiple sets (up to 12), all deadbolts and knobs can be supplied with the same key, making key management easier for homes and rental units.
• Steel adjustable latch: The latch fits door thicknesses from 1-3/8 in to 1-3/4 in and supports backsets of 2-3/8 in or 2-3/4 in, so it will work on most standard residential doors.
• ANSI Grade 3 verified: The hardware is tested to more than 200,000 cycles, indicating reasonable mechanical longevity for entry-level residential use.
• Versatile styling: The flat black finish pairs with contemporary, transitional, and traditional interiors for consistent curb appeal across home styles.

Who It's For

This combo set suits homeowners, landlords, and renovators who want a matched entryset with a modern flat black finish and the convenience of keyed-alike locks for up to 12 sets. It is a good fit for exterior doors where a simple thumb-turn deadbolt and lever handle are appropriate.

It is less suited to heavy commercial use or locations that require the highest security standards; buyers seeking heavy-duty, premium security hardware or specialized keyed master systems should look elsewhere.
