To ensure the technical key security of a mechanical locking system, it is essential to choose a system that is protected by key patents and offers high-level technical key copy protection.
MTL™ 800 keys feature a patented double alpha spring - a moving element located at the tip of the key blade - which engages with two unique pins at the rear of the cylinder, creating an additional shear line for enhanced security.
The MTL™800 platform is patent protected in Australia until 2039, whereas the MT5+ patent expires in 2025. The MT5+ system used in VPI locks will continue to be supported to ensure the protection of existing installations. Additionally, all MTL™800 keys are fully backward compatible with existing MT5+ systems in VPI locks.
