Probrico Oil Rubbed Bronze Double Cylinder Deadbolt Lock - Keyed Both

In this review the Probrico Oil Rubbed Bronze Round Double Cylinder Deadbolt is evaluated for homeowners and small businesses that need controlled access from both sides of a door. The single biggest reason to consider this deadbolt is its double cylinder design, which requires a key on both sides and provides an extra layer of security where a thumb turn is undesirable. The review focuses on fit, installation, everyday operation and any tradeoffs encountered while using a keyed both side lock in residential or light commercial settings.

Key Features

• Double Cylinder: Requiring a key to unlock from both sides provides deliberate access control and prevents easy exit via a reachable interior thumb turn.
• Adjustable Latch: The included latch adjusts to common backsets of 2-3/8 in or 2-3/4 in, simplifying fit for standard door preps without additional parts.
• Door Thickness Range: Fits doors from 1-3/8 in to 1-3/4 in, so it works on most residential and many commercial interior and exterior doors.
• Finish Options: Available finishes like oil rubbed bronze or stainless-style tones let it blend with existing hardware and decor for a cohesive look.
• DIY Friendly: The package includes the necessary hardware and straightforward instructions, making installation achievable for many homeowners.
• Versatility: Suitable for front entrances, internal rooms that need controlled access, or private areas in offices and public buildings where two-sided key control matters.

Who It's For

This deadbolt is aimed at homeowners, landlords, and small business operators who prioritize controlled entry and want a keyed solution on both sides of the door rather than a thumb turn. It is particularly appropriate where a second-story window or other vulnerability could make an interior thumb turn a safety concern.

Those who should look elsewhere include users who need quick single-handed egress in an emergency without a key, or anyone who has mobility or dexterity challenges that make key operation on both sides impractical. Also consider other lock styles if you require electronic or smart access features.
