You may well have heard of “cylinder snapping” or “lock snapping“.  Lock snapping is a very common method used by burglars to break into a property that has a euro cylinder lock. Lock snapping requires ZERO skill by the thief to snap the lock. 

Euro lock cylinders prone to lock snapping are found on almost all domestic houses that have UPVC doors, although a significant number of composite & aluminium doors use them too, and they’re often used in commercial as well as domestic environments.

The video below shows the difference that 3Star TS007 cylinder or an SS312 Diamond approved cylinder can make to the security of your house.

3 Star cylinders are intended to break, or snap, but in such a way that it is not possible to manipulate the lock to open the door from the outside. The lock can still be operated from inside by the key or turn.

The first question to ask is “Do I have euro profile cylinders on my doors?” Well, if they look like the picture below, yes you do.

If they are not marked with either the Kitemark and TS007 or with the Diamond approved mark, as those in the picture are, then they will not be resistant to snapping.

The locks must be the correct size. The lock should not protrude more than 3mm from the door or backplate of the handle into which it is fitted. We supply 3Star cylinders in a large range of sizes which means that you will be able to get the right size of cylinder for your door.
