Probrico Black Door Knob and Single Cylinder Deadbolt - Keyed Alike

In this review the Probrico Black Door Knob and Single Cylinder Deadbolt combo is assessed for homeowners and renters who need a complete keyed-alike entry solution. The bottom line: this set is best for anyone who wants a simple, attractive replacement for a front or exterior door that combines a classic rounded knob with a matching deadbolt and comes with multiple identical keys. Its most compelling advantage is durable construction meeting ANSI Grade 3 standards while offering a low-maintenance black finish.

Key Features

• ANSI Grade 3 certified: Built to exceed 200,000 cycles which provides reliable long-term operation for residential use.
• Black anti-fingerprint finish: The wear-resistant, corrosion-resistant coating keeps the locks looking clean and rust-free with ordinary use.
• Combo set convenience: Each set includes an entry knob and a single cylinder deadbolt keyed alike so one key works for both locks.
• Comfortable classic knob: The rounded ball knob has no sharp edges and is easy to grip without hurting hands.
• Universal handing: The locks fit both right handed and left handed doors, simplifying selection during installation.
• Complete hardware pack: Screws, installation instructions and all mounting hardware are included for a straightforward install.

Who It's For

This combo set is ideal for homeowners, landlords, and DIY installers who want an economical, matched knob and deadbolt solution for a front door or other exterior door. The keyed-alike feature and included six keys make it convenient for families or small rental properties that need consistent access for multiple people.

It is less appropriate for commercial doors or high-security applications where a higher ANSI grade or advanced cylinder would be recommended. Buyers who need specialty long screws for thicker doors should check door prep and existing hardware, since some customers reported mixed experiences with screw lengths and face plate alignment.
