Lock snapping (also known as cylinder 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. Police have estimated that around 22 million doors throughout the UK could be at risk from lock snapping. Lock snapping has become more prevalent over recent years as it requires no special tools or expert knowledge. Thieves use tools like hammers, screwdrivers or anything else that can physically grab and take hold of a cylinder to snap the lock. In some instances, burglars can gain access in seconds. A former burglar has testified they would rather snap a lock than use the best lock picking tools because it is a simpler and quicker method of entry.〔(【引用サイトリンク】url=http://www.bbc.com/news/uk-england-leeds-17075027 )〕 == Locks At Risk From Lock Snapping == The locks most vulnerable to this type of attack are fitted with a euro profile cylinder lock, millions of which are fitted to uPVC and double glazed doors. Other security measures in place on doors including shoot-bolts, dead-bolts, roller keeps, and anti lift bars are rendered useless because once the lock cylinder is snapped and removed from the door, the burglar can access the locking mechanism using a screwdriver or similar tool. Once the locking mechanism is bypassed, the door will be unlocked and provide easy access. Certain types of anti-snap locks are specifically designed to prevent this method of attack, which have a section which will snap off and come away if a burglar was to try and break the lock. This allows the locking portion of the cylinder to remain secure, while making the remaining portion shorter and difficult to grasp.〔(【引用サイトリンク】title=Advice relating to Euro Cylinder locks )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lock snapping」の詳細全文を読む スポンサード リンク
