ICS is a completely new mechanical invention by EVVA. A very durable system that is also ideal for very heavy doors. What makes it different? Hidden internal security components in the key. These make unauthorised key copying even more unlikely. The design of the key is seamless: no edges or corners. Just like all other high-grade EVVA systems, ICS also features triple protection: First, technical and technological protection thanks to security features invented by EVVA. Second, patent protection ensuring that only EVVA is permitted to produce and sell these security solutions. Third, a security card for authorised orders of key copies, which can be traced to the organisation.
