This is the last in our series of articles on the characteristics which distinguish a high security European profile cylinder from any other type of cylinder. After seeing how a cylinder can protect against brute force attacks and lock picking/key bumping, we’ll now see what solutions there are to prevent the making of illegal copies of keys. This is an aspect which is often overlooked but, in truth, it is crucially important; it is obvious that if a burglar can easily obtain a copy of the key the cylinder can be opened regardless of all the protections which it may have.

In the first article of this series we have seen how, even though the external shape of the body is basically the same for all, the European profile cylinders are very different from each other with regard to their technical features and, therefore, also in terms of the security level which they can provide.

We therefore know that the main feature of a high security cylinder is its ability to resist brute force attacks, which are the most widespread type. In the previous article we looked in detail at the role played by anti-drill and pull-resistant reinforcements. In this article we conclude the study of solutions which improve the resistance of a European profile cylinder to withstand brute force attacks. Continue reading →
