The DPI double profile integrated system consists of a length profile, a cross-section profile and a pin system, resulting in 3 levels of security. When the key is inserted into the key channel, control is achieved by the ridged plug profile and a profile locking bar, which is controlled via a curve in the body without the need for springs. The "EVVA" lettering imprinted on the key profile guarantees life-long trademark protection for the DPI locking system.

• Optimum wear resistance
• Technical protection (copy protection), organisational protection (security card) and legal key protection (patents)
• The name "EVVA" can be seen on the key profile. As the EVVA brand offers life-long protection, this profile also features life-long protection.
• Available in a compact or modular design
• Special length profile system with strong key cross-sections
• The key is precisely centred by the special profile ridge design, ensuring the key can be effortlessly inserted.
• Continual plug ridge overlap in the scanning area - a minimum of four overlaps - results in an optimum level of scanning protection
• Individual differences in profiles are fully effective - no profile variations in the lower key bitting section.
