40mm Keyed Alike Laminated Steel Padlocks Pack of 12 - Same Key

In this review of the 40mm keyed alike laminated steel padlocks, the bottom line is straightforward: these are a practical, no-frills set for users who need multiple locks that operate with the same key. The twelve-lock pack is aimed at homeowners, small workshops, and anyone organizing storage where convenience matters more than high-security features. The single biggest reason to buy is the keyed-alike convenience combined with a sturdy laminated steel body and a hardened shackle that offers solid everyday protection for gates, toolboxes, and lockers.

Key Features

• 40mm laminated steel body: The laminated construction with 22 layered pieces and zinc coating provides durable resistance to everyday wear and corrosion for indoor and outdoor use.
• Hardened 2 in shackle: The 6mm diameter, 2 in long hardened steel shackle improves resistance to cutting and sawing for routine security needs.
• Four-pin brass tumbler: The brass cylinder offers pick and pry resistance appropriate for general security on gates, sheds, and storage boxes.
• Keyed alike set of 12: You get twelve padlocks that open with the same key, simplifying access across multiple lockers or storage units.
• Two keys per lock: Each padlock includes two keys so spares are available for daily use or for handing a backup to another user.

Who It's For

The pack is best for homeowners, small business owners, and tradespeople who need consistent access across multiple points: think storage lockers, tool chests, garage cabinets, backpacks, duffels, and residential gates. The keyed-alike feature saves time when several locks must be opened frequently by one person or a small team.

Those who need high-security, tamper-resistant locks for commercial high-value assets or for long-term outdoor exposure in extreme environments should look elsewhere; this set is built for dependable everyday use rather than specialty security installations.
