Benefits
MORE INNOVATION
The Medeco 4 system integrates advanced technology, including the movable key element and specialized side and lift pins within the cylinder. These features expand the possibilities for sophisticated lock and key system design.
MORE PROTECTION
Cylinder side pins and a lift pin engage the sidebar, requiring precise alignment for the cylinder to operate. This mechanism effectively protects against bumping and picking techniques. The patent-pending movable element in the key is designed to deter unauthorized 3D printed copies.
MORE COMBINATIONS
Secondary side-pin bittings enable expanded master keying capabilities. Medeco 4 cylinders can be integrated into master key systems that include M4, M4 BiLevel, and M4 CLIQ keys and cylinders.
MORE SECURITY
The patent-pending key control features protect against unauthorized duplication of keys. Medeco requires specific key blanks and a dedicated key cutting machine for duplicating M4 keys, offering multiple levels of restriction to meet diverse security needs.
