When schools require maximum security and flexibility in a master key system – they choose
Unlike conventional locking systems, 4KS uses a unique pinning system of springless carbide sliders that activate two sidebars to eliminate key bumping and make picking and scanning attacks near impossible.
And unlike conventional systems, the addition of these broaching sidebars means 4KS offers an astonishing 133 billion key combinations.
EVVA | Unique security
The unique technology of 4KS offers three different levels of protection against key reproduction, illegal key copies and manipulations:
HOW IT WORKS
In any situation | more protection
4KS is virtually pick proof. This is because of the complexity of the 12 slider’s alignment with not one locking element (shear line) but three.
Bumping relies on spring pressure to work when inserting a specially cut key. 4KS is springless, making bumping virtually impossible, not to mention the key blanks distribution is tightly controlled.
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.
Side bars are anti drill. The slider (Loading pin) are made from Carbide. There are also additional anti drill pins strategically replaced in the cylinder to increase drill resistance.
Schools can use 4KS to install complex master key systems, that will provide them with security and added expansion with even the most difficult and intricate systems.
Plus the unique four-curve system of 4KS allows individualised key profiles. Blanks from another school or organisation’s 4KS system will never work in your system.
