janus8000: The right choice – not only in terms of security
The janus8000 cylinder is not only versatile and flexible in use, but also provides effective protection against tampering attempts thanks to premium drill and pull protection. In addition, a new precision mechanical locking mechanism ensures enhanced key copy protection—standard for cylinders with registered locking.
Key copy protection
The new locking mechanism makes illegal copying of the janus8000 reversible key more difficult, thus guaranteeing the exclusivity of your keys. This innovative approach ensures that only authorized individuals have access to duplicate key orders, significantly enhancing your security measures.
Drill protection
Additional protection against drilling attempts is provided by hardened components and sophisticated engineering. This combination minimizes the risk of a successful break-in and ensures maximum security for your locking system, giving you peace of mind.
Modular design
Flexible overall length allows easy adaptation to new doors, providing customized solutions for different requirements. Modular design: Flexible overall length enables easy adaptation to new doors.

Standards and security requirements
The janus8000 reversible key system combines high-quality standard features with a variety of special functions and meets standards such as EN 1303 and DIN 18252. Ideal for complex master key systems—in commercial as well as private sectors with registered locking.
cylinder lock for locks
The EN 1303 standard covers cylinders for locks and defines requirements for their security against unauthorized opening and resistance to attack. It categorizes security classes based on criteria such as effective differs, number of movable tumblers, drill protection, and torsional strength of the cylinder. This standard is crucial for assessing the security of mechanical locking devices and is often combined with other standards to perform comprehensive security evaluations.
profile cylinder for door locks
The DIN 18252 standard covers profile cylinders for locks and defines requirements for their locking and attack resistance. This standard includes various security classes, which are determined by specific tests of the mechanical resistance of locking cylinders. In particular, it regulates BZKB drill/picking protection as well as resistance to physical attacks such as drilling or pulling out the cylinder. Compliance with this standard is important to ensure security in burglary-prone areas.
suitability for fire protection
Approved for use on fire and smoke protection doors
SKG resistance class 3
Products with SKG class 3 certification offer the highest protection against burglary attempts. This classification is ideal for areas exposed to particularly high security risks.Features of SKG class 3:
- Resistance time: These products withstand forced entry attempts for a longer period and thus provide significant resistance.
- Application area: Suitable for residential buildings, commercial properties, or other objects where a high level of security is required.
VDS
Profile cylinders with this marking are available in VdS version.

Patent term of the product
GMK system
A grand master key system (GHS) is a complex type of master key system that is often used in large building complexes such as administrative buildings, universities, or hotels. These systems consist of many differently keyed cylinders, which are organized into different hierarchy levels or keying groups.The superior grand master key can operate all cylinders in the system, thus offering high flexibility in the management of access rights. In a GHS system, group-based assignment of keying numbers can also be carried out to maintain an overview of the various authorization levels.
This structure makes it possible to set up differentiated access authorizations and ensures that certain keys can only open specific doors, while other keys offer more comprehensive access options.
