The 4 Best Padlocks for Gates, Sheds, and Lockers of 2026

By Gayle Woods Editors Updated 4 products scored

A padlock is the one piece of hardware you never think about until the morning it won't open. I've stood at a gym locker with a key that wouldn't turn and at a shed hasp I could have sworn was stainless. The gap between a lock that lasts and one that quits doesn't announce itself on the shelf — it shows up in February, in the rain, with somewhere to be.

Over four months, we ran 16 padlocks through the places they actually live: locker rooms, gate hasps, shed doors, and a truck-bed job box. What separated them was the small stuff — whether the numbers were readable in a dim hallway, how many keys came in the box and whether two locks could share one, and how the shackle and finish held up to rain and road salt. Hardened steel and weather-resistant coatings sound interchangeable on the packaging. They aren't.

The picks below cover lockers, outbuildings, and everything in between, so start with where the lock will hang and how often you'll be opening it.

A padlock is mostly shackle, and this one has the toughest in the group: an octagonal boron-carbide shackle that Master Lock rates 50 percent harder than hardened steel, set into a laminated steel body with a cover over the keyway and the shackle notches. Those are the two details we check first on anything that lives outdoors, because the shackle is what a bolt cutter goes after and the keyway is what fills with water and freezes shut. On a gate, a shed door, or a job box, it is the lock we reach for first.

The four-pack is the rest of the argument. All four locks are keyed alike, so one key handles the gate, the tack room, the trailer, and the shed, and nobody stands in the rain sorting through a ring of lookalikes. Two keys come in the box and each one opens every lock, so have a couple of spares cut before the locks get scattered across the property. The body is 1-7/8 inches wide with a 5/16-inch shackle and 1-1/2 inches of clearance, enough to close over a gate bar, a chain, or a thick shed hasp.

Small hasps are where it stops being the right lock. A 5/16-inch shackle will not thread the hole on a gun case, a light locker door, or a filing cabinet, and this much lock is wasted on a cabinet inside the house. That is a job for the smaller keyed pair or a combo lock, which is why we keep both around rather than standardizing on one.

Worth Noting

  • Keyhole cover flap works loose
Our Verdict

For gates, sheds, and job boxes, this is the four-pack we point people to: a boron-carbide shackle, a covered keyway, and one key that opens every lock in the box.

Master Lock 40DPF Discus Best for Storage Units and Trailers

Master Lock 40DPF Discus

Storage units, trailers

Field Score 93/100
Shackle
3/8 in. dia, 5/8 in. clearance
Body Width
2-3/4 in. (70 mm)
Body Material
Stainless steel
Shackle Guard
Shrouded
View on Amazon

Everything the Magnum puts out in the open, this lock hides. The 40DPF is a 2-3/4-inch stainless steel disc with a 3/8-inch hardened steel shackle sunk into a shroud, so a bolt cutter gets a curved edge of stainless to slide off instead of a straight run of steel to bite. It is the shape storage-unit doors, cargo trailers, and shed latches are built around, and it is what we reach for on anything with a short, recessed hasp.

The fit is what sold us. Pressed against a storage-unit latch, the disc sits nearly flush, with no gap to wedge a pry bar into and no shackle standing proud to be sawed. The stainless body is also the most weather-forgiving of the four here: salt air and a wet spring do less to it than to a painted or vinyl-covered body, and there is no keyhole cover to lose because the keyway tucks underneath.

One quirk is worth knowing before you hang it. Mounted sideways on a trailer coupler or a gate that sits at an angle, the disc can hold water, and the weep hole only does its job when the lock hangs more or less upright. Mount it shackle-down where the hardware allows and dump it out after a soaking. The shroud is worth that small piece of upkeep.

Worth Noting

  • 5/8 in. clearance won't take a gate bar
  • Key turn is stiff when new
Our Verdict

If your locks hang on storage-unit or trailer latches, this is the one: a shrouded stainless disc that gives a bolt cutter nothing to bite.

FortLocks 4-Digit Combo Best Combination Lock

FortLocks 4-Digit Combo – Gym Locker Lock

Lockers and cabinets

Field Score 92/100
Code
4-digit, resettable
Warranty
Lifetime
Body Size
3.62 x 1.77 x 0.79 in.
Body Material
Hardened alloy steel
View on Amazon

Four big numerals in a row, an orange body you can pick out from the end of the locker row, and no key to lose on the way to the pool. We like this one for a locker or a cabinet you open every day: the numbers are large enough to read without leaning in, which counts for more than it sounds when your hands are full or the light in the changing room is bad.

Four digits and a resettable code are the specifications that change how you live with it. Ten thousand combinations instead of the thousand a three-digit school lock gives you is a modest gain, but the reset matters more: when a code gets shared around a barn, a shop, or a family locker, you set a new one in a few steps instead of buying another lock. The body is hardened alloy steel with a painted finish and a lifetime warranty.

It is a locker lock, not a gate lock. The dials are the exposed mechanism, and a winter of sleet and grit is exactly what makes them stiff, so keep it indoors or under a roof — a changing room, a covered shed, a cabinet — and put a keyed lock on the gate that faces the weather. When the wheels start to drag, clean them out rather than forcing the dial.

Worth Noting

  • Dials can stiffen in freezing weather
  • Painted alloy steel, not stainless
Our Verdict

For a locker or a cabinet you open every day, this is the combo lock we recommend: big readable dials, a four-digit code you can change, and no key to lose.

Puroma Keyed 2-Pack Best for Indoor Lockers

Puroma 2 Keyed Padlock with 3 Keys 7/8" School Locker Lock Gate 40mm Black

Indoor lockers

Field Score 91/100
Keys
3, keyed alike
Pack
2 locks
Cylinder
5-pin brass
Body Width
40 mm
View on Amazon

Three keys for two locks is the sort of small generosity that decides a purchase. The Puroma pair is a 40 mm vinyl-covered body with a hardened steel shackle and a five-pin brass cylinder — one pin more than the four-pin cylinders most budget locks use, and small enough to vanish in a jacket pocket.

Where it earns its place is indoors: a gym locker, a staff-room locker, a filing cabinet, a storage bin. All three keys are alike, so one rides on your ring, one lives in the gym bag, and one stays in a drawer, and the third key is the detail we appreciate most, because a lost key becomes an inconvenience instead of an afternoon with a bolt cutter. The 40 mm body sits on a standard locker hasp without crowding it.

It is not an outdoor lock. Left on a fence, a shed hasp, or a gate, the body and shackle rust and the keyway starts to fight the key, and a padlock that will not turn is worse than no padlock at all. Buy the pair for lockers, cabinets, and bins, and put the Magnum or the 40DPF on anything that faces the sky.

Worth Noting

  • 12-month warranty, not lifetime
Our Verdict

Buy this pair for indoor lockers and cabinets, where three keys and a five-pin cylinder are worth more than weatherproofing, and leave it off anything that gets rained on.

How We Tested Padlocks — and What Actually Mattered

We started with a list of roughly 40 locks sold for outdoor storage, gym lockers, and general security, then cut anything that didn't state a shackle material, came only in novelty sizes, or asked a price that made no sense for what came in the box. That left 16, which we split between the places people really lock things: a gym locker room I use three mornings a week, a backyard shed and gate through a wet spring, a truck-bed job box, and a school locker.

Every keyed lock went onto a ring with its own keys so I could count them and see whether keyed-alike sets genuinely opened every lock in the set. I opened each one one-handed, in the dim hallway by the lockers, to see whether the key caught or the shackle needed two hands to thread through a latch. With the combination locks, I read the dial at arm's length and again with the lights low, noting whether I had to squint or tilt the body toward a window.

Weather resistance got the longest runway. Each outdoor lock hung through weeks of rain, got hosed down on a Saturday, and sat through a stretch of road-salt spray in the job box; at the end I checked for rust bleeding out of the shackle and whether the mechanism still turned without grinding. I also looked at how much shackle was left exposed — the less a bolt cutter has to grab, the better — and whether the body twisted when I leaned on it with a pry bar.

The locks that made the list are the ones that opened on the first try, kept their numbers legible, and never asked me to fight them.

How to Choose a Padlock

Start With the Hasp, Not the Lock

The hole in the hasp decides almost everything. A 1/4- or 9/32-inch shackle is what fits a gun case, an ammo can, a locker door, and most cabinets; 5/16 inch and up is what a gate hasp, a shed latch bar, and a job box are drilled for. Clearance matters as much as diameter: 5/8 inch of shackle is plenty on a recessed latch, while 1-1/2 inches lets the lock close over a gate bar or a length of chain.

Measure the hole and the gap before you order. A small body rattling loose in a big gate hasp can be twisted until something gives, and a heavy discus simply will not thread a gun case.

Keyed, Keyless, or One Key for Everything

A keyed lock opens with one hand and works with gloves on, which is why gates and sheds usually get one; the risk is a lost key and a lock you end up cutting off. A combo lock has nothing to lose but the code, and it is the better choice for a locker you open in a hurry or share with other people.

If several buildings are in play, buy a keyed-alike pack so one key handles the shed, tack room, trailer, and gate. Count the keys that come with it, because most packs ship two keys across four locks and you will want spares cut before the locks scatter.

Weather Is a Materials Question

Anything that faces the sky is going to get water in the keyway and around the shackle notches, and that is where a cheap lock fails first, not at the body. A cover over the keyway, a vinyl or rubber jacket around the body, a brass or stainless body, and a recessed keyway all buy time.

Weather resistant is not waterproof, so read it as slower corrosion rather than immunity. Laminated steel under a cover and a stainless discus are the two constructions we trust outdoors; a painted body and an open keyway are the details that show age first.

Cut Resistance Is About Exposure

A bolt cutter needs a straight run of shackle to bite, so the shape of the lock matters more than its bulk. A shrouded discus leaves a curved edge of stainless and nothing else. A small open-shackle lock leaves 1/4 inch of hardened steel standing in the air, and that is a snip.

Then look at what the lock is hanging on. A heavy lock on soft pot-metal hardware is money spent on the wrong half of the door. Spend on the lock an opportunist can walk up to and keep the cheap ones inside.

Frequently Asked Questions

Final Verdict

Start with the Magnum four-pack. It is the most lock we can put on a gate, a shed, and a job box in one purchase: a boron-carbide shackle, a covered keyway, and a single key that opens all four.

The 40DPF is the better shape where the hasp is short and recessed, on storage-unit doors, trailer couplers, and shed latches, because there is no exposed shackle to cut. And if you want no key at all, the FortLocks combo is the one here we trust for a locker you open every day, indoors or under cover.
