DPE (Double Profile Extended) is a 6+1-pin system. When the key is inserted in the key way, checks are carried out in the cylinder plug by

• a plug rib profile,
• a profile locking bar (which is controlled by a curve in the body; no springs used)
• and an additional control pin.

• The special longitudinal profile system is specifically adapted for the cross-section profile retainer and therefore results in strong key cross-sections.
• Large profile cross-sections of 0.5 mm² in the variable profiles guarantee lasting differentiation between the different profile versions.
• The key is precisely centred by the special profile rib design, ensuring the key can be inserted without any difficulty.
• Constant overlapping of a least 4 plug ribs in the scanning area provides optimum picking protection
• Individual differences in profiles are fully effective - no profile variations in the lower key bitting section.
• Modular design
