We are an expertise in cylinders. Whether you require cylinders in Keyed-Alike, Keyed-Different or of a Master Key system, we can offer various types of keying in Euro cylinders, oval cylinders, rim cylinders or even padlocks.
Key System : Level One
KD is the commonest keying of all types, in which each cylinder has its own unique key (known as "change-key") and can be operated by the other keys in the system.
In KA system, all cylinders of the set have the same key-code and thus can be operated by the same key. This system convenience and eliminates the need for multi-keys where numerous cylinders are used.
Key System : Level Two
Key System : Level Three
Only the GMK can operate all cylinders in the system.
Key System : Level Four
Similar to GMK system, there is no cross-operation between the groups, but a powerful key (i.e. GGMK) which can operate all cylidners in the system.
