Best Truck Tool Box Locks with Keys (2026)

Compared on paper

Specifications are manufacturer rated, as published on each listing and collected 4 November 2026.

How the points were given

Each lock is scored on performance, build, value, safety and warranty. No lock here states a safety listing, so all five score zero for safety. Two of the five state a warranty term: the Cylinnda lists a lifetime warranty and the Sissinda lists 12 months. How we pick explains the weights.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.

What the listings tell you

Five locks are compared here. Four state a 5/8-inch cylinder, and two state a warranty term. Three are keyed alike, one is keyed different, and one states no keying. The listings name paddle-latch compatibility, shuttered keyways and waterproof finishes, but none states a safety listing.

Buying guide: the best truck tool box locks with keys

Cylinder size and panel thickness

Four of the five locks here state a 5/8-inch cylinder. The Cylinnda listing says to measure the locking distance and the door thickness first, since the correct lock size equals the locking distance. The Helonge lock suits panels under 0.47 inch with a keyhole under 0.7 inch, and the Cylinnda locks fit a standard 3/4-inch mounting hole. Match the cylinder to the door before ordering.

Keyed alike or keyed different

Keyed alike means one key opens every lock in the set, and the Cylinnda 8-pack, the Newace 2-pack and the NIANNIAN 2-pack all work that way. The Sissinda lock is keyed different, with a unique code and 2 keys that only open that lock. The Newace key code is random, and the listing says it may arrive as ch502 or ch503. Pick keyed alike for one key across several locks, and keyed different when each lock needs its own key.

Paddle latch fitment

The Newace and Sissinda locks state compatibility with lift-up paddle latches, naming UWS, Dee Zee, Kobalt, Weatherguard and Better Built among others. The Sissinda adds Delta, Husky, Craftsman and Atwood to its list. The Newace listing warns that a few latches use a longer locking tab, so check fitment with the listing pictures before ordering.

Cam locks and shuttered keyways

The Cylinnda and NIANNIAN locks turn 90 degrees clockwise to lock, and the Cylinnda key is removable at the unlocked position. The Newace and Sissinda locks use a shuttered keyway that keeps dust, dirt and rain out of the cylinder. The Cylinnda pack includes 3 lock plates per lock, and the Sissinda lock plate uses a riveted design. A shuttered keyway matters most on a truck box that rides in weather.

Warranty terms

Two of the five locks state a warranty term. The Cylinnda lists a lifetime warranty with 30-day money back, and the Sissinda lists 12 months. The Newace, NIANNIAN and Helonge listings state no warranty term. A stated term is worth more than a service promise, so read the warranty line before ordering.

Garage Fit Check

• Measure the locking distance and the door thickness before ordering; the Cylinnda listing says the correct lock size equals the locking distance.
• Check the mounting hole: the Cylinnda locks fit a standard 3/4-inch hole, and the NIANNIAN locks need a 3/4-inch opening.
• Check the panel: the Helonge lock suits panels under 0.47 inch with a keyhole under 0.7 inch.
• Count the keys: the Newace and NIANNIAN 2-packs come with 4 keys each, while the Sissinda and Helonge singles come with 2 keys each.
