Probrico Double Cylinder Deadbolt 3 Pack - Secure, Keyed Both Sides

In this review the Probrico 3 Pack Black Double Cylinder Deadbolt is examined for homeowners and small businesses that need controlled entry on both sides of a door. The biggest reason to consider this deadbolt is its double cylinder design, which requires a key to unlock from either side and therefore adds a clear layer of access control where turning a thumbturn is not acceptable. The package of three keyed-alike locks suits multiple doors or multi-door properties where consistent keying reduces hassle.

Key Features

• Double Cylinder: Requires a key to unlock from both sides, offering confident access control for exterior or sensitive interior doors.
• Adjustable Latch: The latch adapts to common door preps with a backset option of 2-3/8 in or 2-3/4 in so it fits standard installations.
• Door Thickness Range: Fits doors 1-3/8 in to 1-3/4 in thick, providing compatibility with most residential and commercial doors without extra modifications.
• Design & Compatibility: Available in multiple finishes to match decor and fits standard door preps for seamless replacement of existing hardware.
• Keyed Alike Convenience: All three locks arrive keyed alike so a single key operates multiple doors, reducing key clutter and simplifying access.
• DIY Friendly: Includes hardware and instructions intended to allow homeowners or contractors to install the lock without specialty tools.

Who It's For

The Probrico double cylinder deadbolt is suited to property owners who need strict control over both sides of a door, such as exterior entrances without safe egress through a thumbturn, interior rooms requiring restricted access, and commercial spaces where keyed access from both sides is required. It is also useful for those who want multiple doors keyed alike to avoid carrying many keys.

Those who should look elsewhere include households where fire code or local regulation requires an easy single-action egress without a key, and buyers who prize a thumbturn for emergency exit convenience. Also, if flawless key retention is a must, be aware some users report occasional sticking keys and may prefer a different cylinder design.

Pros & Cons
