In Hammersmith, we're seeing a growing trend toward upgrading to TS007 3-Star anti-snap locks, especially given the vulnerabilities in modern UPVC and composite doors. These locks aren't just about preventing snapping but also guard against bumping and picking. Is your current cylinder actually rated to resist snapping, and would your insurer pay out if it isn't? At Jaspe Locksmith, we fit upgrades that settle both questions.

Although lock snapping might seem like an obscure term, it's a real and prevalent threat to the security of modern doors. This technique targets the euro cylinder on UPVC and composite doors, which many of us have in West London. An attacker grips and levers the cylinder until it snaps, exposing the cam and allowing quick entry. Shockingly, this can happen in under a minute using basic tools.
Our modern doors, especially in areas like Lower Mall and Fulham Palace Road, are at risk. These doors often have entry-grade cylinders that protrude past the handle escutcheon, making them easy targets.
The original developers or landlords might've installed non-anti-snap barrels, which aren't up to the task.
The solution? A TS007 3-Star anti-snap cylinder. It features engineered sacrificial sections that protect the cam even when broken.
This upgrade isn't just cost-effective; it's often required by insurers.

For securing your home in West London, understanding TS007 3-Star and SS312 Diamond ratings is essential. These ratings help us confirm your locks are not only up to standard but also provide the best protection against potential threats like lock snapping, bumping, and picking.
The TS007 3-Star rating signifies that a cylinder can independently defeat these attacks. In contrast, the SS312 Diamond rating involves a more rigorous, independent testing process, often required for high-value properties.
| Rating | Protection Level | Application Example |
|---|---|---|
| TS007 1-Star | Basic security | Standard cylinder without additional hardware |
| TS007 3-Star | Full anti-snap, anti-bump, anti-pick | Single cylinder sufficient for most homes |
| SS312 Diamond | High-level attack resistance | Required for high-value properties |
For Fulham and riverside residents, a correctly fitted 3-Star cylinder is usually sufficient. However, high-net-worth properties might require the Diamond standard. We're here to make sure you get the right fit for your home and insurer's requirements.

Yes — lock-snapping is one of the most common UK forced-entry methods on UPVC and composite doors. Most insurers now expect TS007 3-Star as standard, not just after an incident.
Typically 20-30 minutes per door for a straightforward cylinder swap.
Yes — itemised invoice naming the specific lock, its TS007 rating, and the date fitted. Accepted by all major UK home insurers.
Ensuring the correct cylinder length is essential because a protruding cylinder can easily defeat your lock's security rating. When the euro cylinder extends beyond the door's surface, it becomes an easy target for burglars using snapping techniques.
This vulnerability can undermine even a TS007 3-Star rated lock, which is designed to resist such attacks.
We must choose the right cylinder length for each specific door, considering both the door thickness and the hardware. Standard measurements like 35/35 or 40/40 might work for most, but thicker doors in areas like Chiswick or Brackenbury might require adjustments.
A flush or slightly recessed installation ensures maximum protection.
If the door won't wait, call 020 3974 1701.
