A shed, gate or outbuilding is where a padlock earns its keep. These are exposed, low-traffic, sometimes isolated targets — exactly the conditions a thief prefers. Choosing well is less about brand and more about matching four things to the job: body size, shackle, weather protection and key management.
Start with the threat
No consumer padlock stops an angle grinder. The realistic job is to defeat what a passing thief carries: bolt cutters and a pry bar. That means a hardened shackle and a beefy laminated or solid steel body. Everything else is convenience.
Four things to get right
Body
40–50mm for a shed, 50mm+ for a gate or an outbuilding door. Laminated steel is strong and affordable; solid brass resists rust but is softer. For everything outdoors, a weatherproof body finish matters as much as size.
Shackle
Hardened steel, always. Choose the length by the hasp: standard for a simple staple, long or extra-long for a recessed gate fitting. A long-shackle padlock lets you lock a gate and a chain together.
Weather protection
A covered keyway and a plated body decide whether the lock still works in year three. Where salt or sea air is present, step up to stainless — see the outdoor padlocks collection.
Key management
If one person manages several fittings — shed, gate, toolbox, bike — choose keyed alike so one key opens everything. If different people should not open each other's locks, choose keyed different. Our keyed padlocks come in both, from 2-pack to 50-pack.
By use
| Use | Recommendation |
|---|---|
| Garden shed | 40–50mm keyed padlock, hardened shackle, covered keyway |
| Garden / driveway gate | 50mm+ body, long hardened shackle; or a surface bolt gate lock |
| Outbuilding door | Two locks — a padlock on the hasp plus a Euro cylinder in the door |
| Gate + chain | Extra-long shackle (60mm+) hardened padlock |
Where a padlock is the wrong tool
On a hinged door you actually use, a padlock and hasp is a clumsy target — hasp screws are the weak point. There, a Euro cylinder in a proper lock case, or a smart door lock, is the better answer. Save the padlock for sheds, gates, chains and storage.
Everyday habits that matter more than the lock
Screw the hasp into solid timber or steel, not a soft panel. Keep the hasp tight so a pry bar has nothing to bite. Lubricate twice a year with graphite, and keep a covered keyway free of grit. A well-fitted mid-range lock beats a premium lock on a loose hasp.
Frequently asked
What is the best padlock for a shed? A 40–50mm keyed padlock with a hardened shackle and a weatherproof, covered keyway.
Are keyed or combination locks better for outbuildings? Keyed locks tolerate frost better and cannot be left with the code visible; combination locks suit shared access. Outdoors in winter, keyed wins.
Should I use keyed-alike locks on my property? Yes, if you manage several fittings — one key for the shed, gate and toolbox removes the bunch of keys and the wrong-key problem.
Can a padlock be cut off? A soft shackle, easily. A hardened shackle forces a thief to spend time and make noise — which is the whole point.
