Anti-snap euro cylinders fitted today, nationwide.
Lock snapping attacks account for over 60% of UK burglaries involving a UPVC door. A TS007 3-star anti-snap cylinder makes snapping physically impossible — we supply and fit them in under 30 minutes.

Lock snapping is the most common forced entry method in the UK. Here’s what stops it.
Lock snapping works like this: a standard euro cylinder is inserted into the door with a portion exposed on the outside. A burglar grabs the exposed part with pliers or a wrench, applies force, and the cylinder snaps at its weakest point. From there, the lock’s internal mechanism is accessible with a screwdriver. The whole thing takes under 30 seconds on an unprotected cylinder and makes almost no noise.
The defence is a TS007 3-star rated cylinder. These are manufactured to resist the specific techniques used in snapping attacks — the cylinder breaks away cleanly in the snap zone but a sacrificial insert protects the lock mechanism behind it, so the door stays locked even after the attack. Avocet ABS, Yale Platinum, Ultion and Brisant are the main brands we fit and recommend.
It’s worth being clear about what “3-star” means. The TS007 star rating is for the cylinder plus handle/escutcheon combination, not the cylinder alone. A 3-star cylinder on its own is 1-star. A 1-star cylinder plus a 2-star handle is 3-star. We supply and fit the correct combination — not just the cylinder — so you’re actually protected.
For most UK home insurers, a TS007 3-star upgrade also satisfies the minimum cylinder security requirement. If you’ve had a burglary or near-miss, this is often required before a new claim will be accepted.

Lock snapping: the most common UK burglary method.
Snap attacks work by breaking the external part of a standard euro cylinder. Once snapped, the internal mechanism is exposed and the door opens in seconds — no forced entry, no broken glass, no noise. Many home insurance policies have begun requiring anti-snap cylinders as a condition of cover.
A TS007 3-star cylinder is engineered to resist snapping at the sacrificial break point — even if a burglar does snap the outer section, the internal locking mechanism remains fully intact and the door stays locked.
We fit anti-snap cylinders from Avocet ABS, Yale Platinum, Ultion and Brisant Secure — all TS007 3-star rated and accepted by insurers including Aviva, AXA, Direct Line, Halifax and Admiral.
