High-security system

Locking system Integral – High security system with reversible key

The system Integral is used in case of highest security demands. The extremely complex construction of the Integral cylinder with three planes of angles is protecting the cylinder from intelligent manipulation attempts and prevents the opening of the cylinder by an unauthorized key.


The serial equipment of the Integral cylinder with an additional carbide bridge made of hardened special steel guaranties highest protection against drilling. Integral cylinders can be additionally equipped with VdS class B/VdS*** and thus also meet insurance requirements.
The system Integral fits very well for the realization of very large and complex locking systems with high security demands. It is also used for small locking systems or individual lockings where high security and a high locking comfort are required. The massive reversible key is though offering a very high locking comfort.
An extension of Integral locking systems by electronic components, for example electronic cylinders as well as barrier controls or alarm systems is possible at any time.

Carbide bridge as standard drilling protection

The additional carbide bridge made of hardened special steel, which is standard in system Integral, makes drilling of the Integral cylinder almost impossible. The hard metal bridge and up to 16 active, spring loaded locking elements in the cylinder guarantee high security.

Cylinder with VdS certification

  • Cylinder equipment according to insurance demands
  • Special pinning inside the cylinder core and –housing for highest protection against drilling and picking
  • Labelling with VdS logo and certification number
  • Can only be applied in 6 pin double-, knob- and half cylinders

Combination with electronics

The combination with electronic systems is very easy, due to the Combi Cap and the Skuni Cap. The key can be delivered ex works as mechanic-electronic combination key. A later retrofitting of electronic components can be effected together with the Combi Cap. Also external systems such as alarm systems or time registration and pay terminals can be operated by this hybrid key.
