What is Lock Snapping?

Lock snapping is a popular technique used by burglars and criminals, over the past couple of years, local crime and burglary statistics have seen an increase in break-ins due to this method.  Lock snapping is where force is applied to the cylinder which snaps it in two.  The outside part of cylinder can then be removed which exposes the locking mechanism.  This then gives the burglar access to the locking mechanism and to your home.

This can be done by using a hammer or pliers and burglars can do this in a matter of seconds.  It is a quick and simple method which does not require any skills or experience.  This is probably why burglars use this method of entry because it is so quick and easy.

Locks that have overhanging cylinders and the euro cylinder locks that have not been tested and approved to SS312 Diamond or TS007 3* are at the highest risk of lock snapping.  The best solution to prevent lock snapping is have anti snap locks fitted which No Shut Sure Lock in Bradford can help you with.

Anti-Snap Locks Explained

Anti-snap locks have been designed and tested to minimise and protect against the threat of lock snapping.

The anti-snap lock cylinders have been designed to withstand a huge amount of force compared to normal locks.  A lot of the anti-snap locks that have been produced have a snap line cut into the body of the cylinder.  This is known as a sacrificial snap line and this line snaps in two when force is applied. When this snaps, the locking mechanism stays intact. The locking mechanism is set into a recess at the back which make it harder to grip onto for a burglar.

What to Look for On an Anti-Snap Lock

When you are looking for an anti-snap lock, it is vital that you look for the TS007 Kitemark certification.  This means the lock has been certified by the British Standards Institute (BSI).  The TS007 uses a third-party certification which normally is the Kitemark and they contain a star rating of 1, 2 or 3 stars.

For a cylinder to receive a 3 star Sold Secure Diamond rating, it must have been tested well above the normal standards that are required for the TS007.  This type of rating also means that it has been tested by the Master Locksmiths Association.
