This two-pack expands coverage for multiple compartments or separate tool boxes. The locks are built from premium zinc alloy for long-lasting durability and share the same rustproof and waterproof chrome finish as the single-pack variant. With a 5/8 inch cylinder depth and a 90-degree turn operation, these locks keep valuables secure in vehicles, shops, and outdoor storage. They’re particularly useful for replacements or outfitting a set of lockers or tool chests with keyed-alike access.
Pros include consistent keying, solid build quality, and straightforward installation. Potential considerations are to verify exact mounting hole dimensions and door thickness per your toolbox to avoid fit issues across different models or vintage cabinets.

The pad lock eye offers compatibility with padlocks for added security, and the front metal latch provides a secure closure to deter tampering.

This option is well-suited for 16-inch tool boxes or storage chests and is commonly used in garages, workshops, and job sites where quick access is balanced with theft deterrence.
The design emphasizes user-friendly operation and reliable latching security. When selecting this model, ensure your toolbox dimensions align with the 16-inch platform and that the latch mechanism aligns with your box’s hasp for smooth operation.
Newace Truck Tool Box Lock Replacement – 2 Pack

The locks are die-cast and steel with a stainless steel finish for durability in harsh environments. Each package includes four keys and two keyed-alike cylinders to support multiple access points. A key note is to verify fitment against your specific toolbox latch style, as some latches use longer locking tabs which could affect compatibility.
Durability, ease of replacement, and multi-key access make this set a practical choice for owners who need reliable replacements that cover multiple compartments in a single purchase. When evaluating, check your latch’s dimensions and tab design to ensure a precise match.

Buying Guide: Key Purchase Considerations And Comparisons
- Mounting compatibility: Before buying, confirm the mounting hole diameter (commonly 3/4 inch) and the latching distance. A lock that doesn’t fit will require a replacement or different model, which adds cost and time.
- Material and durability: Zinc alloy bodies with rustproof and waterproof chrome plating offer longevity in outdoor or garage environments. For vehicles and RVs, choose locks rated to resist moisture, dust, and temperature changes.
- Cam design and operation: Look for tubular cam or hook cam configurations that align with your toolbox’s door style. A 90-degree turn opening mechanism is standard and easy to use, with keys removable at unlocked position for convenience.
- Key management: Decide between single lock with multiple keys or keyed-alike packs that let you access multiple compartments with the same key. Consider including spare keys in a safe location.
- Security level: For high-theft environments, pairing a lock with a padlock or adding an additional mechanical latch can improve protection. The front latch should resist prying, and the lock should resist picking and corrosion.
- Brand and compatibility: Reputable brands like Craftsman and Cylinnda offer a range of sizes and configurations. When mixing brands, verify fitment to avoid mismatches with latching distances and cam lengths.
- Installation and maintenance: Choose models with clear installation guides and replaceable components. Routine inspection ensures the cam and latch remain aligned and functional over time.
- Budget and availability: Multi-pack options can lower per-unit costs if you have multiple tool chests or storage needs. Always compare warranty terms and customer support when possible.
Overall, the best toolbox lock will balance fit, durability, and ease of use for your specific storage setup. Whether you need a single lock for a compact toolbox or a multi-pack to secure several compartments, these options cover common tool storage scenarios from home workshops to rugged outdoor environments.
