Anti-Snap vs Anti-Bump vs Anti-Pick | Which Protection Do You Actually Need

Walk into any DIY store in Ilford and you'll find cylinder packaging covered in reassuring words. Anti-snap. Anti-bump. Anti-pick. Anti-drill. Some boxes claim all four at once. The implication is that the more words, the safer you are. That's not how burglary actually works.

The three threats are real. They're just nowhere near equally common, and if you don't know which one your door is actually vulnerable to, you might spend £60 on a cylinder that solves a problem burglars in IG2 aren't using.

Let me rank these properly.

How Burglars Actually Get In: the Numbers

The Office for National Statistics and police data from the Met consistently show the same picture. Snapping is the dominant method of forced-entry on uPVC doors. It accounts for the majority of cylinder attacks in urban Essex, including across Redbridge and Barking & Dagenham. Bumping and picking are, statistically, the minority.

Why? Snapping takes about ten seconds with a cheap tool anyone can buy. No skill needed. Bumping requires a correctly cut bump key, some practice, and a door the burglar has already assessed as suitable. Picking requires real skill and time. Opportunist burglars, the type most common in Seven Kings and Goodmayes, want the quickest exit possible. They're not standing on your path for three minutes picking a lock.

That order matters when you're budgeting.

What Each Attack Actually Is

Snapping. Euro cylinders have a natural weak point where the outer section meets the cam. Apply lateral force, and the cylinder snaps at that point. The outer section breaks off, exposes the cam, and the door opens with a screwdriver. Standard cylinders from the 1990s and early 2000s offer almost no resistance. A huge proportion of uPVC doors across Ilford still have them.

Bumping. A bump key is cut to the lowest possible depth on every tooth. Insert it, apply rotational tension, strike it sharply. The pins jump momentarily and the cylinder opens. It works on any pin-tumbler lock that hasn't been engineered against it. It sounds alarming. In practice, residential bumping is rare because the noise it makes and the time it takes both work against the attacker.

Picking. Single-pin picking, raking, or using a decoder requires the attacker to understand the lock and have the right tools. Skilled locksmiths do it routinely, and so can a patient, trained burglar. The key word is patient. Most residential burglars aren't.

The Standards That Test These Things

This is where I'll ask you to care about a table, because the terminology on packaging is meaningless without it.

A cylinder labelled only "anti-snap" on the box may not have passed TS007 3-star. The label is marketing. The star rating is a tested standard. Check which one you're actually buying.

Which Cylinders Deliver in Practice

For snap resistance on a standard uPVC door in Ilford, the brands that consistently pass TS007 3-star or SS312 Diamond testing are Ultion, Avocet ABS, Mul-T-Lock, and ERA Fortress. Yale's Platinum range achieves TS007 3-star. Expect to pay £35 to £75 for a quality cylinder, depending on size and brand. Anything below £20 that claims TS007 3-star should have a certificate to prove it.

For bump resistance specifically, any cylinder with security pins (serrated, spool, or mushroom) is substantially harder to bump than a standard pin-tumbler. All of the TS007 3-star cylinders above include security pins as part of the specification.

For pick resistance, high-security cylinders from Mul-T-Lock (MT5+), EVVA, and Abloy use different mechanisms altogether, either rotating elements or disc detainers, that defeat standard picking tools. These cost more, from £80 to £200+, and are the right choice if you're protecting a business premises in Cranbrook or a high-value property, not a standard semi in Loxford where snap is the real exposure.

Who Needs What

The typical Ilford homeowner with a uPVC door. A TS007 3-star or SS312 Diamond cylinder is the right answer. It addresses snap (your actual threat), passes bump and pick tests as a by-product, and costs under £70 fitted. Ultion or Avocet ABS are what I'd fit.

Landlords across IG1 to IG6 with multiple properties. Same cylinder recommendation, but also think about BS8621 compliance on any door that's an escape route. Some insurers and local licensing schemes in Redbridge now ask for it.

Small business owners, especially in Barkingside or Gants Hill retail units. Snap is still relevant if you have a euro cylinder on an aluminium door. But pick resistance matters more here, because a commercial premises is a higher-value, less-overlooked target. Consider Mul-T-Lock or EVVA, and look at the whole door system rather than just the cylinder.

Timber doors with a mortice lock. Snapping isn't the issue. BS3621 five-lever compliance is. Bumping and picking are relevant, and a quality mortice lock with hardened steel bolt and anti-pick levers, from brands like Union or Era, handles both.

The One Exception

If you live in a flat in Newbury Park or Clayhall with a communal entrance and your flat door is your only barrier, pick resistance moves up the priority list. Communal doors get propped open. Someone determined enough to reach your flat door probably isn't an opportunist. That's the scenario where spending more on an Abloy Protec2 or Mul-T-Lock MT5+ is justified.

For everyone else: snap is the threat, TS007 3-star is the fix, and the rest of the words on the box are largely reassurance.

If you're not sure what cylinder is currently on your door, it takes about 30 seconds to check. Look at the face of the cylinder: if it's flush with the door furniture or protected by a sacrificial ring, someone's already thought about this. If it protrudes more than a few millimetres beyond the handle plate, it's likely vulnerable.
