Anti Snap Locks in Harrow — TS007 Cylinders Supply and Fit
Lock snapping is still one of the most common forced entry methods in the UK, and the HA area is no different. The technique takes seconds with basic tools — a burglar snaps the outer section of a standard euro cylinder, reaches in with a screwdriver, and the door is open. Anti snap cylinders stop this. They have a sacrificial section that breaks off before the lock mechanism can be reached. We supply and fit TS007 3-star rated cylinders across Harrow and surrounding areas: Wembley, Pinner, Northwood, Stanmore.
How snap attacks work
A standard euro cylinder can be snapped by gripping the outer end and applying force. On cheaper cylinders, the snap point is at the key entry slot, and once the outer section is broken off, the internal cam can be turned directly with a screwdriver. The process takes under 30 seconds. Anti snap cylinders have a designed sacrificial section that breaks away from the lock body at a point before the internal mechanism — the door stays locked even after the outer section is removed.
TS007 3-star: what the rating means
TS007 is the British Standard for cylinder security. 3-star is the highest rating, covering anti-snap, anti-pick, anti-drill, anti-bump, and anti-manipulation resistance. Most UK insurance policies now specify TS007 3-star cylinders as a requirement for euro cylinder locks on external doors. We fit 3-star rated cylinders from reputable UK suppliers as standard.
