Anti-Snap Lock Upgrades in Brixton
Worried about lock snapping in Brixton? Standard euro cylinders can be snapped in seconds; anti-snap cylinders rated to TS007 (3-star) are built to defeat the attack. We upgrade uPVC and composite doors in one visit, matched to your multipoint system. Call 07984 547185 for an honest assessment.
Lock snapping is the burglary method that targets the euro cylinder itself: grip the protruding cylinder, snap it, and the locking mechanism is exposed. It works against standard cylinders in under a minute, and it is the reason so many uPVC and composite doors in South London are secured by locks weaker than their owners believe.
The fix is an anti-snap cylinder — engineered with sacrificial sections that break away safely while the core stays protected. Fitted correctly, flush with the handle, it closes the attack off. This page explains what to look for; the upgrade itself takes one visit.

TS007 star ratings explained
TS007 is the British standard that rates cylinder security against snapping and other attacks. One star means the cylinder alone resists attack to a defined level; three stars means it resists on its own, without needing extra hardware. A 1-star cylinder paired with a 2-star security handle also reaches the 3-star overall rating.
What matters in practice: look for the stars, not the marketing words. 'Anti-snap' without a TS007 rating is a claim; TS007 3-star is a tested fact. We fit rated cylinders and will show you the markings on the cylinder we install.
Is your door vulnerable? A quick check
Stand outside and look at your euro cylinder. If it protrudes beyond the handle or escutcheon, it can be gripped — that is the vulnerability. A correctly fitted cylinder sits flush, giving an attacker nothing to grab.
Even a flush standard cylinder is still snappable, just less conveniently. The upgrade question is not only about protrusion but about the cylinder's rating. If your cylinder has no star markings and your door is uPVC or composite, an upgrade is worth considering.
- Cylinder protrudes from the handle — vulnerable, fix the fit or upgrade
- No TS007 stars visible — unrated against snapping
- TS007 1-star — decent, consider pairing with a 2-star handle
- TS007 3-star, fitted flush — properly protected
What the upgrade visit involves
We measure the existing cylinder, check the multipoint gearbox it works with, and fit a TS007 3-star cylinder in the correct size — flush with the furniture, which is half the security. The door is tested through its full lock cycle, and you get the new keys plus the old cylinder back.
One honest caveat: a 3-star cylinder protects the cylinder. The door, frame and hinges still matter. If the frame is rotten or the door flexes, we will say so — security is a system, not a single component.
Frequently asked questions
What is lock snapping?
An attack where the protruding part of a standard euro cylinder is gripped and snapped off, exposing the locking mechanism. It defeats unrated cylinders fast. Anti-snap cylinders to TS007 are engineered with sacrificial sections that break away safely while the lock stays secure.
How do I know if my cylinder is anti-snap?
Look for TS007 star markings on the cylinder face: 3-star is the highest standalone rating. No markings means unrated. We can identify what you have on a visit and recommend honestly — call 07984 547185.
Will an anti-snap cylinder fit my existing door?
In most cases, yes. Cylinders come in sizes to suit the door and handle positions, and we measure before fitting. The key detail is fitting it flush — a 3-star cylinder protruding from the handle still gives an attacker something to grip.
Is anti-snap worth it on a uPVC door?
It is the single most effective upgrade for a uPVC or composite door, because the cylinder is the known weak point. Pair it with a sound multipoint gearbox and correct door alignment for the full benefit.
Does my insurer require a specific lock standard?
Many policies ask for BS3621 on timber final exit doors; for cylinders, insurers increasingly recognise TS007. Check your policy wording — we will match the upgrade to what it requires and show you the ratings on what we fit.
