Dimple Keys GP Cylinder – 18-Pin High Security Lock with 12 Billion Key Combinations
The Dimple Keys GP Cylinder is a next-generation high-security locking solution designed for advanced access control and large-scale master key systems. Engineered with 18 high-precision stainless steel pins arranged in three rows, this cylinder delivers exceptional resistance against picking, manipulation, and unauthorized entry.
With an incredible 12 billion key differences, the GP Cylinder provides superior key control and maximum protection for residential, commercial, and high-rise building projects.
Advanced 18-Pin Security Technology
Unlike conventional cylinders, the GP Cylinder features:
- 18 high-precision pins in 3 rows
- All upper pins designed as anti-picking pins
- Stainless steel construction with special lubrication coating
- Nearly impossible to pick due to advanced internal structure
This original security design offers powerful resistance against picking, bumping, and other illegal unlocking techniques, making it ideal for high-security environments.
12 Billion Key Variations for Maximum Key Control
One of the strongest advantages of the GP Cylinder is its 12 billion possible key combinations, drastically reducing duplication risks and ensuring enhanced security control in complex buildings.
This makes it highly suitable for:
- Office buildings
- Residential towers
- Hospitals
- Hotels
- Government facilities
- Industrial sites
Flexible Master Key Systems (MK, GMK, GGMK, RMK, CNK)
The GP Cylinder supports advanced key management configurations including:
- CNK (Change Key System)
- MK (Master Key)
- GMK (Grand Master Key)
- GGMK (Great Grand Master Key)
- RMK (Reverse Master Key)
Thanks to the use of Master Key (MK) pins, the cylinder can be integrated into large-scale and complex master key systems without compromising security.
Great Grand Master Key (GGMK) System – Smart Access Control for Modern Buildings
With increasing building heights and growing complexity in access management, traditional locking systems are no longer sufficient. The GP Cylinder allows the creation of a Great Grand Master Key (GGMK) system, enabling:
- One single GGMK to open all locks
- Multiple GMK groups with independent Grand Master Keys
- Organized hierarchical access control
- Efficient management of large properties
This flexible system allows property managers and security administrators to design an optimal key structure tailored to the building’s security requirements.
User-Friendly Reversible Dimple Key Design
The ergonomic dimple key offers:
- Smooth insertion and removal
