Anti-Snap vs Anti-Bump vs Anti-Pick | Which Matters Most

Most lock packaging now reads like a bingo card. Anti-snap. Anti-bump. Anti-pick. Anti-drill. Some add anti-extract for good measure. Manufacturers aren't wrong to list these, but they're not telling you how likely each attack actually is, and that ordering matters enormously when you're deciding what to spend.

Let me do the ordering for you, based on what the data shows and what we see on doors across Stony Stratford, Calverton, Hanslope and the MK11 postcodes.

The Three Attacks, Explained in Thirty Seconds Each

Snapping strips the front section of a Euro cylinder off with a metal bar or similar tool, exposing the internal cam that operates the latch. Takes under a minute on a standard cylinder. Requires no skill and no special knowledge, just hardware you can buy anywhere.

Bumping uses a specially cut key and a sharp knock to momentarily align the pins inside the lock, allowing it to turn. It's the kind of thing you see demonstrated on YouTube. Effective on older pin-tumbler cylinders. Much less so on cylinders made in the last ten years with anti-bump pins.

Picking is the classic image, a bent wire, a tension wrench, a patient criminal. In reality it takes practice. A lot of it. An experienced picker can open a basic cylinder in under a minute, but an experienced picker is not the person trying your door handle at 2 a.m. in Old Stratford.

How Common Are These Attacks, Really?

The Home Office doesn't publish a breakdown by method, but the evidence from police forces and insurance research is consistent. Snapping dominates.

The ERA-commissioned research that prompted widespread adoption of TS007 standards found that snap attacks accounted for roughly 60 percent of lock-specific forced entries on uPVC doors. More recent data from Avocet's research with West Yorkshire Police pointed to similar figures. Bumping has declined sharply since anti-bump features became standard, and picking remains statistically rare in residential burglary, mostly because it requires skill and time.

The real picture, simplified:

So if a lock shouts "anti-pick" loudest on its packaging but doesn't mention snap resistance, it's selling you armour for your elbows when your knees are exposed.

Who Actually Needs What

Snapping: everyone with a Euro cylinder

If your front or back door has a Euro cylinder, which is the oval-shaped lock with a keyhole in the middle, you need snap protection. Full stop. This covers the vast majority of uPVC doors across Galley Hill, Fullers Slade, New Bradwell and similar estates in MK11 and the surrounding villages. Timber doors fitted with Euro locks are equally vulnerable.

The minimum you should have is a TS007 3-star rated cylinder. That's the British standard that actually tests snap resistance by applying a defined force to the protruding part of the cylinder. It's not a marketing claim, it's a test. Brands that pass it at 3-star include Avocet ABS, Ultion, Mul-T-Lock MT5+, and ERA Fortress among others. Expect to pay £40 to £90 for the cylinder itself.

If budget allows, pair a 1-star cylinder with a 2-star door handle/escutcheon, which also earns a combined 3-star rating under TS007. Either route works.

Bumping: worth having, nearly free to get

Every decent cylinder sold today includes anti-bump features. Spool pins, mushroom pins or similar mechanisms that resist the momentary alignment a bump key relies on. You don't need to seek this out separately. If you're buying a TS007 3-star cylinder for snap protection, bump protection comes with it.

If you have a very old cylinder, say a basic Yale or unbranded unit fitted before 2010, it may lack anti-bump pins. Worth replacing on that basis alone, though snapping is still the bigger reason to act.

Picking: rarely the priority, but relevant in one specific situation

For almost all homeowners in Stony Stratford and the surrounding villages, picking is not a realistic threat. It's relevant to high-value commercial premises, properties that have had targeted intelligence-led break-ins, or anywhere that bump-resistant locks are already fitted and an intruder has escalated to a more skilled approach.

If you genuinely want picking resistance, look at cylinders using sidebar mechanisms or disc detainer technology. Mul-T-Lock MT5+ uses a sidebar. Abloy Protec2 uses rotating discs rather than pins, making conventional picking essentially impossible. These cost £100 to £200 fitted, and for most Stony Stratford homes, that money is better spent elsewhere. Installing a door chain, upgrading door frame fixings, or fitting a Sold Secure Diamond padlock to a vulnerable outbuilding gate will do more for your overall security.

The One Cylinder That Covers All Three

If you want to buy once and stop thinking about it, a TS007 3-star cylinder from Avocet ABS, Ultion or Mul-T-Lock MT5+ covers snap, bump and pick in a single unit. All three brands also carry SS312 Diamond grade approval, which is Sold Secure's cylinder-specific rating and requires passing snap, bump and pick resistance tests.

For a standard front door in Wolverton, Cosgrove or Deanshanger, an Ultion or Avocet ABS fitted by a locksmith will typically cost £80 to £130 all-in, depending on cylinder size and whether the existing handle and escutcheon need attention. That's the whole job.

The Exception Worth Knowing

Mortice deadlocks work differently. A BS3621 five-lever deadlock, the kind found on timber doors in older Stony Stratford properties near the high street, doesn't have a Euro cylinder and isn't vulnerable to snapping. Anti-snap is irrelevant here. Anti-pick and anti-bump still apply, because five-lever locks can be picked or have their levers manipulated. A BS3621 lock from Chubb, Union or Yale tests for this. If yours is old and worn, a replacement is wise, but snap resistance is not the selling point to chase.

The Recommendation

Prioritise in this order:

1. Snap resistance first. TS007 3-star cylinder if you have a Euro lock on any external door.
2. Anti-bump comes with the territory. Any decent modern cylinder includes it.
3. Anti-pick last. Most homes don't need specialist picking resistance. If you do, Mul-T-Lock MT5+ or Abloy Protec2 are the realistic options.

Don't let a longer list of features on a cheap cylinder persuade you it's better than a shorter list on a tested one. A £15 cylinder claiming anti-snap hasn't necessarily passed TS007. Check the certification, not the copy.
