How do drill-based break-in techniques work?

Drills are used in break-in techniques in three main ways:

Cylinder drilling

This method involves using a drill to bore into the front of the cylinder of locks and padlocks, thereby destroying or damaging the pins. This allows thieves to subsequently insert a simple flat-bladed screwdriver to manipulate the rotor and unlock the device.

Rotor extraction (or ‘pulling’)

This method involves drilling into the cylinder’s rotor and inserting a self-tapping screw into it. This is then hooked by a special tool which extracts the rotor, thus allowing unhindered access to the heart of the lock and enabling the opening mechanisms to be operated.

The frame-drilling technique

This technique is mainly used on windows and French windows. A hole is drilled into the frame immediately below the handle. A shaped metal rod is then inserted into this hole, allowing the handle to be operated from the inside.

 

How can you protect your home against these break-in techniques?

Cylinder drilling

  • Fit a high-security anti-drill cylinder with steel pins and balls to protect the rotor and the cylinder body (such as Mottura’s Champions® cylinders).
  • Add a Defender® device, an armoured protection with steel inserts and a magnesium anti-drill plate that acts as a shield to protect the cylinder.

Rotor extraction (or ‘pulling’)

The frame-drilling technique

  • Add additional security locks to your windows, such as minibars, to provide an extra layer of security beyond just the handle and lock.

  • Europrofile Champions® Cylinders

    The range of Champions® security cylinders includes different cylinder models, each of which is characterized by particular technical qualities, different types of allowed key duplication and the numerous new applicable functions.

    Each set of keys, sealed at the origin, is accompanied by the personal ownership card to be showed while requesting key duplicates.

    The cylinders are divided into Silver Series (C10 and PRO/Modular), Gold Series (C28PLUS, C39 and CP6) and Platinum Series (C55 and C3D). All models have common safety features; furthermore, each cylinder is characterized by different mechanical systems, increasing the level of security, or in combination with each other to increase the level of complexity of the cylinder itself.

    All Champions® Europrofile security cylinders are certified according to the UNI EN 1303 standard at the highest achievable levels, including resistance to Bumping, Picking and Tracing manipulation techniques.

  • Mechanical Defenders®

    Mechanical Defenders® are the most popular type of armoured door protection. With steel spheres inserted at various points in the Defender's body, a protective manganese plate and other security mechanisms that vary for each model, they effectively protect the cylinder against break-in attempts using methods such as drill, pick and percussion blows. The use of the key is permitted through a small shaped hole.

  • Magnetic Defenders®

    Magnetic Defenders® add an additional level of protection for your security door lock compared to traditional mechanical models. A special cover completely seals the keyway and can only be rotated to show the keyhole using a special magnetic key. Only once the cover is fully rotated can the key be inserted to open the door. 

    The magnetic Defender® is the best form of protection against acid attacks, as well as against break-in attempts such as the use of a drill, pick, percussion blows and extraction of the cylinder rotor.
