If you have a uPVC or composite front door (as most of the UK does), there’s a very good chance it has a euro-cylinder lock. They’re a common lock choice – cheap, easy to install and use. But they have one very well-known weakness. They can be snapped. Lock snapping is still one of the most common burglary techniques in the UK. This is mainly because it’s fast, quiet and doesn’t really require any skill. Which is why anti-snap locks have now become one of the most important security upgrades for homeowners. But what does anti-snap actually mean?
What is Lock Snapping?
Lock snapping is a common break-in technique, where the burglar targets the cylinder that sits within the door handle. If the cylinder slightly protrudes beyond the door handle, then it can be gripped with tools and deliberately broken in two. One that’s one, the internal locking mechanism can be manipulated, and the door can be opened in seconds. Standard cylinders are particularly vulnerable to this type of attack, because they’re made from softer metals and don’t have any reinforced break points.
What Makes a Lock Anti-Snap?
Anti-snap locks have been specifically engineered to resist exactly this type of attack. But they aren’t just built with stronger metal. They’re also designed with specific security features that prevent snapping from leading to entry. There are a few things that allow them to do this:
Sacrificial snap sections: Anti-snap cylinders are designed with pre-set weak points at the very front of the lock. So rather than trusting the structural integrity of the metal throughout the lock, there is a ‘sacrificial snap point’. If pressure is applied, only the outside part of the cylinder breaks off. This leaves the internal locking mechanism protected and inaccessible, so the burglar can’t get in.
Reinforced core and hardened steel: High-quality anti-snap locks contain hardened steel bars, along with reinforced internal structures. These additions strengthen the cylinder and make it significantly harder to break.
Anti-pick and anti-drill features: Most anti-snap cylinders also include extra protection on top of the two above. These can be things like anti-pick pins, anti-bump technology and anti-drill plates, which means you’re not just protecting against sapping, but other common break-in techniques too.
TS007 3-Star rating: In the UK, the highest recognised standard for euro cylinders is the TS7007 3-star rating. A 3-star rated cylinder has been independently tested against snapping, drilling, picking and other forced entry methods. If your cylinder doesn’t display a visible 3-star mark, then it might not be strong enough.
The Benefits of Anti-Snap Locks
Stronger protection against burglars: Because lock snapping is so common in the UK, upgrading right away addresses a major vulnerability in many homes.
Improved insurance compliance: Many insurers require British Standard or TS007-compliant locks. Installing anti-snap locks will help ensure your policy is still valid.
Cost-effective security upgrade: Compared to installing a full alarm or CCV system, upgrading to anti-snap locks is relatively affordable, while still significantly improving your door’s resistance to attack.
Peace of mind: Maybe the biggest benefit of them all is confidence. Knowledge that your door can’t be opened in seconds by anyone with access to Google provides a lot of reassurance, especially if you live in an area where burglaries are frequent.
If you’re not sure what type of lock you have, then a quick inspection by a locksmith will let you know. After all, your front door is the first line of defence for your home – so if the cylinder can be snapped, the rest of your security doesn’t really matter. Anti-snap locks are specifically designed to prevent break-ins, so they really are the best option you have.
