Lock Snapping
What is lock snapping?
Lock snapping is a method of forced entry used by burglars
that targets a weakness found in the older style euro cylinder locks. Rather
than attacking the door itself, an intruder applies force directly onto the lock
cylinder, causing it to break at a weak and vulnerable point. Once the cylinder
is snapped, the internal locking mechanism can be easily accessed, allowing the
door to be unlocked.
This technique has become so common because it is fast,
relatively quiet, and requires only basic hand tools. In many cases, an
experienced burglar can snap a vulnerable lock in under10 seconds!
Why lock snapping works so easily on older locks
Older euro cylinder locks were never designed to resist
snapping attacks. Back when they were invented lock snapping wasn’t a known
issue. Older euro locks lack reinforcement in critical areas.
Although modern doors may look secure with multiple locking
points, the euro lock cylinder itself is usually the weakest part. This is why
even properties with solid modern doors can still be vulnerable if the cylinder
has not been upgraded to anti snap.
Which doors are vulnerable to lock snapping?
Any door fitted with a standard or older euro cylinder lock is
at risk. These locks are extremely common across the UK and are found in the
vast majority of homes and commercial properties.
You’ll normally find these vulnerable cylinders on uPVC
doors, composite doors, patio doors, and conservatory doors. Many people assume
that a multi-point locking system automatically points to high security.
However, while these doors lock in several points, the entire system is
controlled by the euro cylinder.
How burglars carry out a lock snapping attack
In a typical lock snapping attack, force is applied to the
door handle allowing part of it to be removed, exposing a bigger section of the
cylinder making it easier to apply force. The cylinder then breaks at its
weakest point, separating the outer section from the internal lock mechanism.
Once snapped, the remaining part of the lock can be manipulated, allowing the
door to be opened without the need to smash glass or force break the door
itself.
Because the attack is quick and doesn’t create a lot of
noise, it is often carried out at night time.
How to tell if your lock may be vulnerable
Many homeowners are unaware that their locks are at risk
until its too late. However, there are some common signs that your euro
cylinder may be vulnerable to snapping.
If your lock is several years old and has never been
upgraded, there is a much higher chance it does not offer protection against lock
snapping. Cylinders that stick out beyond the door handle are also more vulnerable
as they are easier to grip. In many cases, vulnerable locks will not display
any recognised security rating on the front such as a star rating are British
Standard kitemark.
If you are unsure, we can assess your locks and advise
whether it offers adequate protection.
What is an anti-snap lock?
An anti-snap euro cylinder is specifically designed to
resist lock snapping attacks. Instead of breaking at the known weak point,
these cylinders contain reinforced sections and sacrificial break points. If
force is applied, the cylinder will break in such a way that it prevents access
to the locking mechanism, making it impossible for a burglar to unlock the door.
Modern anti-snap cylinders are tested against recognised
security standards and are far more resistant to snapping, bumping, drilling,
and other common attack methods. Upgrading to an anti-snap cylinder is one of
the simplest and most effective ways to improve your home or business security.
Common misconceptions about lock snapping
One of the most common misconceptions is that having a
multi-point locking door or just a brand-new door means lock snapping is not a
concern. In reality, the strength and quality of the door mean very little if
the cylinder that is controlling it, is weak.
Another assumption is that newer doors always come fitted
with anti snap locks. While many do, some are actually still supplied with
basic cylinders unless an upgrade is requested when the door is purchased. It’s
also worth noting that lock snapping does not only happen under cover of
darkness. Many incidents are reported during the day when properties are left
unoccupied.
Improving security without replacing the door
One of the advantages of fitting anti snap locks is it’s a quick
and straightforward job. For most doors upgrading the lock to anti snap is all that’s
needed to completely overhaul the security of the door. This makes it a
cost-effective way to protect your home without incurring any major costs.
We can recommend suitable options based on the type of door
you have to maximise security.
