Lock snapping is a burglary technique which involves snapping a particular type of lock cylinder in two by applying the right amount of force and removing the outside part to expose the locking mechanism. Once the locking mechanism is exposed, it's open to tampering which allows the door to be unlocked using simple household tools.
There are now many ‘anti-snap’ locks on the market, some are very secure and some are not.
Lock snapping has become the preferred method of attack against many homes. Recent BBC and ITV reports have highlighted significant increases in this method. Police crime statistics indicating it is used in over 30% of burglaries in some areas.
If the door lock on your front door, back door, garage door or any other door in your home looks like this, then the answer is YES! but we can help!
In short, they snap.
But they are engineered to snap in the right place and a long way in front of the vulnerable central section that gives access to the multi-point-lock or dead lock. Due to the small size and shape that the cylinder has to squeeze into it would not be possible to make a cylinder strong enough to withstand the enormous applied pressure of the mole grips whilst still being affordable.
The concept is that when the burglar grabs the end of the cylinder just the tip snaps off leaving more metal in front of the central target area.
Most lock snapping attacks involve ripping off the door handle first, so it doesn’t matter if your locks stick out past the handle. Watch this video to see how we snapped a door handle.
A cylinder that boasts a sacrificial end is not guaranteed protection. We have tested many where the lock has still snapped in the centre and not on the sacrificial cut as designed.
Looking to the standards for guidance can just confuse. Until 2012 the EN1303 cylinder kite mark test included no real snapping test. Then TS007 kite mark was introduced, if the cylinder passed this test it got 3 stars – if it failed it still got 1 star and a kitemark! So even today a kite marked cylinder is not a snap secure purchase.
We have tested all TS007 3 star locks on the UK market and found that many held out for considerably less time than the October 2012 test criteria. We don’t know why this is, but it is why we test everything we sell to make sure that what you buy does what we say it does – not just what the manufacturer says.
