4-CURVE DESIGN
The key is reversible meaning it can be inserted either way making operation simple. The 4-curve design incorporates additional security ensuring the system is suitable for deployment in the largest and most complex master key systems. Unlike most master key systems that rely on spring pressure in the cylinder, the 4KS sliders (locking pins) inside the cylinders are actively moved by the tracks in the key. This active operation means 4KS will outperform all others in challenging environments be they dirty, dusty or salty.

NATIONAL NETWORK
EVVA 4KS is available through a national dealer network. The network consists of a select group of locksmith companies that have met the strict dealership appointment criteria.

HIGH STRENGTH KEYS
Key breakage is a very common problem with some master key systems. This can be caused for many reasons, such as the key material being too soft or deep cuts in the key located at critical leverage points (which means the key is easily damaged by the user). The 4KS key is manufactured from high grade nickel silver and is extremely difficult to damage or break. The unique design ensures the key is not weakened regardless of the location of the cuts.

COMPLEX STRUCTURE
Not all master key systems have the ability to create a hierarchy of keys to suit the requirements of very large sites. 4KS is designed to provide a highly complex multi-level master key system that can be scaled for future expansion as needed.

ENVIRONMENT
When it comes to performance in challenging environments, the active sliders and springless design in 4KS provides an edge that is unmatched by other systems. As a key is inserted, most master key systems rely on small springs to push the locking pins into place. Even small amounts of dust, dirt or grit can affect the operation of the cylinder. Thanks to the 4KS springless design, when the key is inserted into the cylinder, the sliders (locking pins) are actively moved into place by the tracks of the 4KS key. This provides industry leading operation and reliability in the harshest of environments.

IMPRESSIONING
Impressioning is a covert method of producing a functioning key. Impressioning relies on marks being left on a blank key that are then filed to produce a key. Due to the frictionless design of 4KS this is virtually impossible.

DRILLING
The control bars within the cylinder are anti drill. The sliders (locking pins) are made from carbide. There are also additional anti drill pins strategically placed in the cylinder to increase drill resistance.

PICKING
4KS is virtually pick proof. This is because of the complexity of the 12 sliders alignment with not one locking element (shear line) but three.

BUMPING
Bumping is a method of covert manipulation to open a cylinder and relies on spring pressure to work when inserting a specially cut key. Due to the unique 4KS design, making a bump key is virtually impossible. Furthermore, the key blanks distribution is very tightly controlled.
