EVVA 4KS master key system provides maximum security. It is SCEC approved and includes SL3 Products. And is suitable for large complex systems providing for future expansion.
The system utilises a unique springless technology that provides industry leading operation and reliability in the harshest of environments,
It is extraordinarily difficult to reverse engineer and has three separate systems which guard against key tampering and illicit copying.
The EVVA 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. 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 – thus ensuring the system can be scaled for future expansion as required. 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 track in the key. This active operation allows the EVVA 4KS master key system to outperform all others in harsh challenging environments (dirty, dusty, or salty).
