Anti-Snap locks: What Are The Benefits?

What Is Lock Snapping, unfortunately, is a very simple technique burglar use to gain entry to your home. It can be done in a matter of seconds and takes very little skill or effort, all that a burglar needs to do is apply force to the lock cylinder. This is often done by using a hammer or other household tools which allow them to snap the lock cylinder into two parts. A burglar does not need any skills or experience to do this. When the lock cylinder is broken in two, the burglar the burglar can then reach the locking mechanism. They would then manipulate the lock to gain entry to your home in a matter of seconds.

How Do Anti-Snap Locks Work?

Lock manufacturers have designed high security anti-snap cylinder locks to combat the risk of the lock snapping technique. Included within these cylinders are anti-snap lines, known as sacrificial lines.

When force is applied to the lock cylinder, it will break along the anti-snap line leaving the centre of the cylinder intact. As only this section breaks, it makes it more difficult for the burglar to grab the cylinder and break into it. This means that your door will remain locked and will stop the burglar from gaining entry via the door.

Do I Have Anti-Snap Locks Fitted?

In most cases it is not obvious that you have an anti-snap lock fitted just by looking at it. You would have to remove the lock from the door and see if it has the snap line on it, although this is not recommended as you could reinstall it incorrectly leaving your property at risk. If the lock sticks out of the door casing by just a few millimetres, then a burglar could use a tool to grab the lock and pull it out.

If you are eager to have an anti-snap lock installed, then it would be advised that you enlist the help of a professional locksmith. If you are keen to purchase an anti-snap lock, then we would advise that you seek advice from a professional locksmith. A qualified locksmith will measure your door and order a cylinder that is the right size to fit your specific door. A locksmith will also make sure the cylinder does not stick out of the door casing and is fitted properly.

Anti-Snap Locks Recommended By The Police
