Locks with Keys 12 Pack Brass Keyed Alike Weatherproof Padlocks

Our review of these CINCINNO keyed alike padlocks finds them to be a practical, budget-friendly choice for anyone needing multiple matching locks for outdoor or indoor use. The single biggest reason to buy is the combination of a solid brass body and hardened steel shackle that delivers real corrosion resistance and reliable security across a range of uses, and the fact that all 12 locks share the same key simplifies key management for storage areas, gates, and gym lockers.

Key Features

• Solid brass body: The 1-9/16 in (40 mm) wide brass lock body offers corrosion resistance and a substantial feel that holds up to outdoor exposure.
• Hardened steel shackle: A 1/4 in (6.5 mm) diameter shackle with 9/10 in (23 mm) length provides strong cut and pry resistance for everyday security needs.
• Keyed alike set: All 12 padlocks use the same key, which simplifies access when securing multiple doors, gates, or lockers.
• Two keys per lock: Each padlock ships with two keys (24 keys total) so users have a spare for daily use or emergencies.
• 4-pin cylinder and dual locking: The 4-pin cylinder and dual locking lever construction increase resistance to tampering and forced entry.
• Weatherproof design: The combination of brass body and hardened shackle is intended for indoor and outdoor use, including gates, trailers, and storage units.

Who It's For

These padlocks suit homeowners, small business owners, and facility managers who need multiple keyed-alike locks for consistent access across storage units, garage doors, outdoor gates, trailers, gym lockers, and warehouse doors. The set is especially useful where managing a single key for many locks reduces complexity and downtime.

They are less appropriate for high-risk locations that demand specialized high-security systems or extremely long shackles; users who need electronic, programmably keyed, or ultra-high resistance burglary-grade locks should look at dedicated security hardware instead.

• Hardened steel shackle and dual locking give good pry and cut resistance for routine security.
