Most of the locks on replacement doors rely on a ‘euro' profile cylinder or ‘oval’ profile cylinder to operate the locking mechanism. In recent years there has been a steady increase in the numbers of burglaries where these cylinders have been attacked to gain entry. The police have known about these problems for several years, but because in the early days the techniques were used rarely and were confined to only a few locations around the UK, these problems were deliberately not broadcast to the public at large for fear of making the problem a lot worse. Instead, the security industry quickly developed measures to protect the cylinders from these attacks.
Even if your door has multiple locking points, with hooks and deadbolts, your door could still be forcefully opened within a matter of seconds. ‘Lock snapping’ or ‘cylinder snapping’ as it is also called is probably the most common method used by burglars to break into properties with a euro cylinder lock.
As a considerable percentage of domestic properties have uPVC doors that contain euro cylinders, a huge number of people can stand to be broken into with considerable ease. When you consider that many composite and aluminium doors also use euro cylinder locks, the number of properties at risk from lock snapping is monumental. By breaking this cylinder, burglars can then manipulate the rest of the lock and have a door open very quickly.
Lock Snapping is not the only threat to a euro cylinder but there is a rapid growth in the use of the technique. Lock Bumping, Lock Drilling, Lock Picking and Plug Pulling are also concerns. Fortunately, manufacturers like UAP and Yale invest heavily in developing features to combat the threats and upgrading to one of their high security euro cylinders can be done easily and at little cost.
