WOOCH Cabinet Cam Locks Keyed Alike Set
The WOOCH set offers keyed-alike tubular cam locks, enabling one key to operate all included locks. This is advantageous for securing multiple cabinet doors, tool boxes, or drawers with a single keyset. The 5/8” cylinder length and 3/4” outside diameter support panels up to 3/8” thick, suitable for both metal and wood surfaces. The zinc alloy construction with a chrome finish provides durable, corrosion-resistant protection. Best for: workplaces or homes where a single keying system simplifies access control. Caution: ensure panel thickness and borehole alignment match the 5/8″ cylinder to prevent binding.
Helonge Truck Tool Lock With Keys
The Helonge lock comes with a key pair, featuring a 3/4″ outer cylinder diameter and a 5/8″ cylinder length. It is designed for panels under 0.47″ thick and supports a compact keyhole size. Best for: RVs, trailers, mailboxes, or compact tool compartments where a quick, reliable lock is needed. Caution: verify panel thickness and latch compatibility before purchasing, as some latches may require a slightly different tab length.
NIANNIAN 1 Pack Black Toolbox Locks
The 5/8″ borehole toolbox lock by NIANNIAN is keyed-alike and designed for a 3/4” opening with a 90-degree turn to unlock. Made of premium zinc alloy with rustproof chrome plating, these locks resist corrosion and stand up to daily wear. Best for: upgrading drawers, tool chests, or cabinets requiring a consistent locking mechanism. Caution: check the borehole size and panel thickness to ensure proper fitment before purchase.
NIANNIAN 2Pcs Locks With Keys
This package includes two tubular cam locks and four keys, all keyed alike. Cylinder length is 5/8″ with a 3/4″ opening, and the body uses stainless steel construction for durability. Best for: replacing or upgrading locks on multiple compartments with the same keying system. Caution: random key codes may be issued, so plan key management accordingly to avoid duplicate codes across systems.
Cylinnda Black Toolbox Lock With Keys
The Cylinnda lock features a 5/8″ cylinder depth and a slightly offset hook cam with a 2.12″ long cam. It includes a 90-degree opening action and a removable key in the unlocked position. Best for: standard toolbox upgrades or replacements where a durable zinc alloy body and chrome finish are desired. Caution: verify the latching distance and door thickness to ensure the standard 3/4″ mounting hole aligns with your box.
Buying Guide
What panel thickness and borehole matter?
Measure your box or cabinet panel thickness and the borehole size to ensure the lock fits. Most tubular cam locks target a 3/8″ to 1/2″ thickness, with 5/8″ cylinder holes being common. If your panels are thicker or thinner, you may need a different model or a longer cam.
Keying: keyed-alike vs. individual keys
Keyed-alike sets simplify access when multiple compartments share one key. If separate access is needed, choose models sold as individual or non-keyed-alike variants. Consider how you will manage keys to avoid loss or unauthorized access.
Materials and durability
Look for zinc alloy or stainless steel bodies with rustproof chrome finishes for longevity in workshops and outdoors. Durability matters for security and weather resistance in RVs, trucks, or vending setups.
Compatibility and installation
Check compatibility with metal and wood panels and confirm mounting hole dimensions. Installation is typically quick and requires only basic tools. Packaged sets often include extra keys and mounting hardware for convenience.
Best-for scenarios
- Best for single-key access across many compartments: WOOCH or NIANNIAN keyed-alike sets.
- Better for RV or trailer applications: Helonge with its panel thickness spec.
- Choose this if you need ready-to-install replacements with multiple keys: NIANNIAN 2Pcs or Cylinnda sets.
What to avoid
Avoid locks that do not clearly specify panel thickness or mounting hole size. Unclear dimensions can lead to improper fit or compromised security. Also avoid products that ship with random key codes if you require consistent access control across multiple units.
Installation tips
- Double-check dimensions with a tape measure before ordering.
- Test fit the lock in the mounting hole prior to final installation.
- Keep spare keys in a secure place and note the key codes if provided.
