Anti Snap Locks & Bump Resistant Locks

Your Guide to Anti Snap Locks, Anti Bump Locks and Lock Snapping

What is Lock Snapping?

Lock snapping is a burglary technique that involves breaking into a property by snapping the door's euro cylinder lock in half. Euro cylinder locks are commonly used on uPVC, Timber and Composite doors making it a common mode of burglary throughout the UK for both domestic and commercial properties.

Lock snapping is done by breaking away the outer casing or escutcheon of the lock to expose the door cylinder. Using a simple gripping tool, burglars can then break the cylinder and expose the locking mechanism. At this point, a tool such as a screwdriver or chisel can be used to gain access.

As the name suggests, lock breaking is a very quick and easy way to break into a property. Lock snapping can be done with absolutely no skill and can be done in just a few seconds. Fortunately, modern door hardware innovations can prevent lock snapping attacks.

How to Prevent Lock Snapping

To prevent lock snapping, homeowners and businesses can utilise anti-snap locks as a reliable and effective measure against potential attacks. These snap resistant door locks are designed to withstand and deter lock snapping attempts, providing an added layer of security for properties. By incorporating anti-snap locks into their security systems, individuals can significantly reduce the risk of unauthorised entry through this method of attack, enhancing the overall security of their premises.

What are Anti-Snap Locks?

An anti-snap lock maintains the same profile as a euro-cylinder lock, however has a number of extra defensive measures to prevent illegal access through lock snapping.

The purpose of an anti-snap lock is to deter burglars and make it extremely difficult for them to expose the cylinders locking mechanism. By using anti-snap locks, home and business owners can significantly enhance the security of their homes and better protect their valuables from break-ins.

How do Anti Snap Locks Work?

Anti-snap locks are specifically designed to thwart lock snapping attempts. Below, we will explore some of the unique mechanisms that make anti snap locks effective at preventing break-ins.

Snap Channel & Break-away Section

The most crucial feature anti-snap locks share is a line carved along the first quarter of the cylinder known as a snap channel. This channel encourages a lock to snap at this point, rather than the midpoint, if it were to be snapped illegally. By breaking at these predetermined weak points, the lock effectively renders the remaining sections useless, preventing any further manipulation of the locking system. This innovative design ensures that even if an intruder manages to snap the lock, they would still be unable to gain unauthorised access.

Anti-pick Pins and Drivers

Anti-pick pins are specialised pins that are inserted into the lock cylinder. These pins are designed to have irregular shapes or specific grooves, making it challenging for lock-picking tools to manipulate them. The purpose of anti-pick pins is to disrupt the picking process by requiring precise positioning and movement of the pins within the cylinder. This added complexity makes it significantly more difficult for intruders to pick the lock successfully.

Anti-drill Pins

Anti-snap locks often have anti-drill pins, which are hardened steel pins placed within the cylinder. These pins make it difficult for burglars to drill into the lock and compromise its security. In addition to their role in preventing drilling attacks, anti-drill pins offer an added layer of resistance against other forms of forced entry. By incorporating anti-drill pins, the lock also becomes more resistant to picking attempts, as the hardened steel pins are designed to withstand the pressure exerted by lock-picking tools. This not only enhances the overall security of the lock but also increases the time and effort required for an intruder to bypass it.

Additionally, its important to note that some insurances may prefer or require anti-snap locks.

Identifying an Anti-Snap lock: How do I know if have one?

As previously mentioned, anti-snap locks are not identifiable once installed – so how can you tell if you have an anti-snap lock?

Anti-snap locks will feature a line that wraps around the circumference of the cylinder within the first quarter of its length; this encourages the lock to snap at this point, rather than at the midpoint, where the locks can be located.
