10 Best Locks For Uhaul Trucks in 2026

A 4-digit combination with 10,000 possible codes means you can set a unique lock code and never carry a key for your U-Haul. The weatherproof stainless steel body and hardened steel shackle resist rust, freezing, and corrosion, so this lock holds up through rain, snow, and road salt without jamming. The round shielded design protects against bolt cutter attacks. That combination of keyless convenience and real outdoor durability is why this lock suits anyone who wants a straightforward, reliable way to secure a rental truck without worrying about lost keys or weather damage.

At 0.6 pounds, this lock is light enough to toss in a glove box or backpack without weighing you down. The 3/8-inch shackle diameter works with standard hasps on gates and sheds, though owners with extra-thick hardware might want to check clearance. For a single U-Haul trip where simplicity and weather resistance matter most, this DELSWIN padlock delivers exactly what it promises.

A 4-digit disc lock with 10,000 combinations gives you more security than a traditional 3-digit model, and the hardened steel shackle adds real cut resistance. The round shielded body is designed to minimize shackle exposure and protect against bolt cutter attacks. This lock is built to operate smoothly in bad weather, cold, or rain without the dials sticking, so you won’t be left fumbling at the gate in bad weather. It suits anyone who wants a reliable, keyless lock that can handle the elements and still keep the cargo secure.

And unlike a keyed lock like the BRINKS Shielded Discus Padlock, there is no backup key if you forget your code. The 0.7-inch shackle height also limits what hasps or latch holes it can fit. For the driver who wants weather-tough, combo convenience without worrying about lost keys, this is a smart pick.

A three-pack of keyed-alike puck locks means you can secure multiple trailer doors with a single key, which is a real time-saver when you’re loading or unloading a U-Haul at a busy lot. The hidden shackle design makes cutting difficult, and the aluminum alloy body with surface oxidation coating won’t rust or corrode after seasons of rain and snow. For anyone who wants a straightforward, grab-and-go lock set that works across trailers, containers, and truck doors, this is a practical fit.

The biggest thing to know is that these locks use a physical key, no combination dial. If you lose that key, you’re stuck until you find a spare. Compared to the DELSWIN Outdoor Combination Padlock, which works with a 4-digit code, the AUTOBOTS three-pack lets you use one key for all three locks, which saves hunting for the right key. You don’t get the quick, fumble-free access of a combo lock. If you’re okay carrying a key and want a lock that resists rain and corrosion, plus a hidden shackle that’s hard to cut, this set makes sense for outdoor use.

Twenty-four padlocks in one box means you can secure multiple gates, sheds, trailers, or storage doors all with the same key. The stainless steel body resists rust in many weather conditions, and the compact disc shape slips into tight hasps easily. For situations where you need many locks that work together without juggling different keys, this set simplifies the process. The keyed-alike design means you can give a spare key to a helper and they can open any lock, which cuts down on confusion.

The shackle is only 3/8 inch in diameter, so it offers decent cut resistance for temporary use but isn’t built for long-term high-security needs like a storage yard or construction site. If you need something tougher, the BRINKS Shielded Discus Padlock comes with a chrome-plated body for more attack resistance, though you get only three locks instead of twenty-four. For a single-day move or a weekend rental where convenience and coverage matter more than brute force, this set gives you the numbers advantage without sacrificing weather protection.

A shackle cut strength up to 8100 lbs means this lock resists bolt cutters and saws longer than many standard padlocks, making it a strong deterrent for securing storage sheds, garages, or construction site storage. The shielded disc design minimizes shackle exposure, protecting against cutting tools. The four-pin brass tumbler cylinder adds pick and pry resistance. This lock is a good fit for anyone who wants heavy-duty physical protection without worrying about combination codes or a weak lock failing under attack.

The BRINKS padlock’s steel shackle has a cut strength up to 8100 pounds, so it’s built to resist bolt cutters and saws in high-risk spots like construction sites or storage sheds. The 70mm body and chrome-plated, hardened shackle also add physical heft that discourages tampering. Because the three locks come keyed alike, you only need one key for multiple doors, which saves fumbling when you’re securing a shed and a toolbox at the same time.

Weighing in at 11.7 pounds, this lock is built from heavy-duty hardened steel with a rust-resistant coating, so it’s clearly meant for serious cargo security, not light duty. It locks the innermost vertical locking bars together on container and semi-truck swing doors, and its adjustable range covers everything from a 10-foot container to a 53-foot trailer. For anyone hauling valuable cargo, this lock resists bolt cutters, hammer attacks, and breaker bars, and it installs in seconds without any tools.

The main drawback is weight and compatibility: at 11.7 pounds, this lock is heavy to carry around, and it only works on swing doors with vertical locking bars, not roll-up doors. If your U-Haul has a roll-up cargo door, you would be better off with the Equipment Lock Rolling Door Lock, which is designed specifically for that setup. But for a standard box truck with swing doors, the NAKANEKO provides a level of theft deterrence that smaller padlocks like the DELSWIN Outdoor Combination Padlock simply cannot match. That is thanks to its full-coverage steel structure and targeted anti-attack design.

A #201 stainless steel body with a solid brass cylinder resists corrosion, so these locks hold up against rain and humidity on a fence or storage unit. The hardened steel shackle, rated HRC 50-55 with a chrome-plated finish, is designed to resist sawing, which adds a layer of security for a trailer or container. The key retain system means the key can only be removed when the lock is locked, so you won’t accidentally leave it unlocked. These features make it suitable for sheds, trailers, trucks, pods, containers, fences, and self-storage units.

You get ten locks keyed alike, which is convenient for multiple access points, but it requires carrying a key. Compared to the DELSWIN Outdoor Combination Padlock, which uses a combination instead of a key, this Unity lock means you have to keep track of a key. If you prefer not to carry a key, a combination lock may be simpler. But if corrosion resistance and a uniform key system are priorities, this pack offers a practical solution for securing multiple locations.

The SEWACC Round Keyed Padlock uses a stainless steel body and shrouded shackle to fend off rust and cutting tools, which matters when your storage unit sits in rain or a dusty lot. Its keyed design means you need to keep track of the key, but the two-pack includes two keys per lock so you can stash a spare. This lock suits anyone who wants durable, weatherproof security for gates, sheds, or storage unit doors, especially when you need a reliable keyed option.

The compact 2.4-inch body and light 0.7-pound weight won’t bridge very thick hasps or oversized latch plates on some larger doors. Compared to the heavier AUTOBOTS Puck Lock, which is designed for trailer doors, the SEWACC feels better suited to standard storage unit latches and shed doors. If your application has an unusually thick locking bar, you might need a bigger lock, but for typical uses this one keeps things simple and secure.

A layered laminated steel body with stacked plates helps resist prying and heavy abuse, while the thick 3/8-inch (9.5mm) hardened steel shackle resists cutting and sawing attempts. The dual ball-bearing locking mechanism holds up under repeated use, and the protective bumper base helps absorb knocks and reduces metal-on-metal scuffs on doors, hasps, and equipment. This four-pack is keyed alike, so you can lock several points on a single property without juggling different keys.

At nearly three pounds for the set, these locks are heavier than a disc-style lock like the DELSWIN Outdoor Combination Padlock, which also skips the need for keys. And because all four are keyed alike, you lose the ability to lock different areas with separate keys. That is fine if you’re securing one location, but less flexible if you need distinct locks for different gates or compartments. Still, for straightforward security on a budget, the Kwikset delivers where it counts.

Sliding the lock behind the door handle and adjusting the U-lock plate to match your specific latch secures the handle in the downward/locked position, preventing the door from being forced upward. For anyone renting a U-Haul with a roll-up rear door, this dedicated approach offers security that a simple padlock on the outside cannot match. The lock fits handles up to 5 inches high and 1.25 inches thick, so it works on most standard roll-up door latches found on trailers and box trucks.

At nine pounds, this is not something you toss in a glove box; it stays with the truck or gets packed in a toolbox. And it only fits roll-up handles up to five inches high and 1.25 inches thick, so it will not work on a standard swinging door or a smaller latch. Compared to a lightweight disc padlock like the DELSWIN Outdoor Combination Padlock, this lock is heavier and less portable, but it is designed specifically for roll-up door handles. If your trailer or box truck has a roll-up door, the added weight is part of the security design.
