Are Cheap Padlocks Any Good | The Honest Answer

I cut open a £18 padlock last month. Took eleven seconds with bolt croppers from a van that every tradesman in Southborough owns. The owner had used it on a shed in Bidborough stuffed with about four thousand pounds' worth of landscaping kit. He knew it wasn't a great lock. He just hadn't thought about what that actually meant in practice.

So let's sort this out properly. Because the answer isn't 'cheap padlocks are rubbish, always buy expensive.' It's more interesting than that.

The myth: a padlock is a padlock

People treat padlocks like they're interchangeable. They grab one off the shelf at a DIY shed, see it's got a solid-looking body, and assume it'll do the job. The logic seems reasonable. It's made of metal. It locks. What else is there?

Quite a lot, as it turns out.

Padlocks vary enormously in three things that actually matter: how hard the body is to destroy, how resistant the shackle is to cutting or cropping, and how hard the lock mechanism is to pick or bypass. A £20 padlock might pass one of those tests and fail the other two completely. Most do.

What CEN grades actually mean

There's a European standard for padlocks, the EN 12320 scale, that runs from Grade 1 to Grade 6. Grade 1 is the lowest. Grade 6 is what you'd put on a high-security commercial site.

Here's the thing most people don't know: the vast majority of padlocks sold in UK hardware shops and online don't carry any EN grade at all. They haven't been tested. The grade is simply absent from the packaging, often because the manufacturer knows the result would be embarrassing.

Grade 3 is roughly the minimum I'd recommend for anything you actually care about. A decent Grade 3 padlock, something like an Abus 55/40 or a Squire SS50CS, starts around £25 to £35. Grade 4 and above from brands like Abloy, Mul-T-Lock or Squire's Stronghold range will run you £60 to £150 and upwards. For a well-stocked shed in Pembury or a commercial unit near Paddock Wood, that is not money wasted.

Open shackle vs closed shackle

This matters as much as the grade, maybe more.

An open-shackle padlock, the classic upside-down U shape, exposes the shackle on both sides. Bolt croppers go straight on it. Even a hardened shackle can be defeated if the attacker gets a good clean bite. I see open-shackle locks on shed doors all over Southborough Common and High Brooms. Most of them would come off in under thirty seconds if anyone bothered.

A closed-shackle padlock shrouds most of the shackle inside the body. The amount of exposed metal that bolt croppers can grip is tiny. That single design change makes a dramatic difference to real-world resistance, regardless of what grade it is. If you're buying a padlock for anything worth protecting, closed shackle only. Non-negotiable.

Paired with a quality closed hasp and staple (not the flimsy stamped-steel ones, look for a Squire or Abus heavy-duty hasp fitted with coach bolts, not wood screws), a decent closed-shackle padlock is a genuinely solid deterrent.

Where a cheap padlock is actually fine

I'm not going to pretend price always equals necessity. There are situations where a £12 padlock from a discount shop does the job perfectly well.

• A garden gate into a garden that has no other valuables in it. You're keeping kids and dogs in, not deterring thieves.
• A suitcase on a domestic flight. You're satisfying airline rules, not stopping a determined person.
• A locker at a gym or leisure centre. Low-risk environment, short exposure times.
• Securing a tarp or cover where the item underneath has no real value.

The test I use mentally: if someone walked off with what's behind this lock, would it hurt me financially or practically? If the answer is no, a cheap lock is fine. If the answer is yes, you need to spend more.

Where a cheap padlock is genuinely dangerous

The shed with tools is the obvious one. I've been to three jobs in the last year, two in Tonbridge and one up near Speldhurst, where tradesmen lost thousands in tools because the shed padlock gave up without a fight. In every case the lock cost less than £25. In every case the tools inside were worth between two and eight thousand pounds.

Other situations where I'd call a cheap padlock false economy:

• Any outbuilding storing bikes, especially e-bikes. Those are theft magnets right now.
• Gates to side access where someone could work unseen. Time and privacy are what a burglar needs.
• Storage units and self-store facilities. Some facilities actually mandate a minimum security grade.
• Anything securing a caravan, trailer or plant equipment.

A Squire SS50CS closed-shackle padlock is about £45. A Mul-T-Lock C13 closed-shackle with a restricted key profile is around £90. If your shed holds three thousand pounds' worth of kit, neither of those is a significant outlay relative to the risk.

The pick-resistance question

Most cheap padlocks use a basic pin-tumbler mechanism with soft brass pins and minimal tolerances. Someone with a tension wrench and a basic pick can open them in seconds. I know because I do it for a living when people are locked out.

Higher-grade padlocks use dimple key profiles, disc-detainer mechanisms (Abloy's patented system is excellent), or tight machining tolerances that make picking genuinely difficult. If pick resistance matters to you, look at Abloy Classic or Protec2 mechanisms, or Mul-T-Lock's Interactive range. These aren't cheap, but they perform.

For most domestic sheds and gates, picking is actually less likely than cropping. Attackers take the fastest route. Protect against the realistic threat first, which means shackle protection and a decent hasp.

What to do instead of guessing

Before you buy any padlock, answer two questions. First: what's the realistic threat, quick opportunist or someone prepared to spend time? Second: what's actually at risk behind the lock?

For low-value, low-risk situations, buy what you like. For anything worth protecting, spend at least £35 and buy closed shackle, a Grade 3 or above, and a solid hasp fitted properly. If you're not sure what 'fitted properly' means, ask someone who does this for a living before you fit it. A hasp screwed into soft timber with four short wood screws is barely better than nothing.
