  • Lock snapping the problem

    In as little as 13 seconds an intruder can get past a standard euro cylinder door lock using simple DIY tools. Lock snapping break-ins are increasing and is one of the most common methods of forced entry into homes.

    Most UPVC doors are secured with a replaceable barrel known as a Euro Profile cylinder as shown. Over the past few years there has been a rise in forced entry break-ins using a method know as lock snapping.


    New standards have now been developed to test a euro cylinder's resistance against snapping attacks.

    The common euro cylinder lock on most homes has a major weakness located around the screw fixing position which means when pressure is applied the lock simply snaps.

    Once this happens the cam that operates the door bolt falls away - allowing access within seconds!

    It doesn’t matter how many hooks and bolts your door has, the euro cylinder is the weakest link.

    Burglars are aware of this weakness and lock snapping break-ins are rising as a result.

    The Police are urging homeowners to review their locks to upgrade to new TS007 British Kitemark 3 star and Sold Secure Diamond rated locks.
