What is a euro cylinder?

A euro cylinder is a part in the door lock that can be changed easily, this can also be referred to as a door barrel. The euro cylinder is a self-contained part which turns the actual lock mechanism inside the door. The construction of the euro cylinder is essentially a series of pins which meet with a pattern on the key, so when the key is inserted it allows the barrel to be turned, this allows the cam to turn in the center unlocking the door.

What is lock snapping?

Burglars have discovered what the locksmith and hardware industry have known for years. It doesn't matter how many hook or dead bolts you have on your door, the weak point is the cylinder lock.

Lock Snapping is a method to exploit a vulnerability in the Euro door cylinder, as the title implies this where the cylinder is snapped and a special tool is used to unwind the locks on your door. The weakest point on a euro cylinder is the middle fixing screw and if too much of the cylinder protrudes from the door this can be clasped and twisted to break the cylinder.
