Mister Shut uses different types of locks depending on the requests and needs of our customers.

Until recently, the most requested and commonly installed lock was the double bit lock. The choice to no longer fit this type of lock on Mister Shut products derives from the fact that the techniques used by burglars are evolving, making this type of lock unsafe and outdated.

For this reason Mister Shut uses European cylinder locks, in the ”gear” and ”throw” versions. The European cylinder lock operates by means of a shaped cylinder.

The lock assembly consists of:
Lock body
European cylinder
Lock protection
Controdefender

LOCK BODY
The lock body corresponds to the metal box, the locking mechanisms and the latch.
A European lock is reliable when the materials with which it is built are resistant and of high quality as well as having traps inside that are triggered when it is tampered with.

EUROPEAN CYLINDER
There are different models and brands of European profile cylinders
The security of a cylinder is given by their internal components and by the relative opening key and its profile. In fact, burglars tend to manipulate the very well-known cylinders with the Italian profile, which is available in all shops and hardware stores.
The choice of a cylinder must be made taking into account the protected duplication of the key, carried out only with security paper or certificate, without which the duplication of the keys cannot be carried out

DEFENDER

The defender is the front protection of the cylinder. The defender’s function is to resist attacks on the cylinder for as long as possible. The best defenders are equipped with details and shapes that make them anti-tube; anti-drill; anti-cut and an anti-tear device with widia pins designed to protect the cylinder barrel

COUNTER DEFENDER
The counter defender prevents the cylinder from being expelled towards the internal side, since by letting a tool similar to a chisel pass through the key guide slot of the defender, after a few impacts it is possible to make the cylinder come out from the internal side of the house, and once freed the cylinder seat with a properly shaped ferrule, you can move the lock throws and enter in a few moments.
