IKON SK6 Multiprofile plus


High-quality IKON profile in special class SK6 with 6 active spring-loaded locking elements. In addition, a total of three different coding types are positioned on both sides or on one side of the key. These codes are scanned in the locking cylinder by up to 9 special springless blocking elements. Missing codings on the key lead to blocking of the locking process. Due to the special arrangement and geometry of the coding on the key, increased key copy protection is achieved. Compared to conventional key profiles, the type of lateral key profile control leads to a considerably higher degree of protection against unlocking and opening.

This system is available for reorders only.

For new systems, we offer the
IKON SK6 radii profile extra und IKON SK6 radii profile plus series.

IKON Standard drilling protection

Core extraction protection:

To prevent core or lock cylinder extraction, the core extraction lock is available with extraction protection and integrated drilling protection AB=3 for profile cylinders (VdS approved). The core with core extraction protection is always supplied without surface treatment in nickel silver.

Core pulling lock

Weather protection:

  • corrosion-protected design
  • cam and forend screw made of rustproof material
  • surface finish: matt chrome plated

Emergency and danger function:

This function enables the locking cylinder to be locked/opened even if a key with locking authorization is inserted on the opposite side (e.g. for front doors and emergency doors).

Emergency and danger function


The profile cylinders which have a freely rotating cam are designated as freewheel cylinders.
The cam can be moved freely through 360° when no key is inserted.
When the key is inserted, the spring-loaded clutch engages in the cam. This then allows the cylinder to be closed in the conventional way with the key.

  • Usually only necessary for special panic or automatic locks. If in doubt, please check with the door manufacturer.
  • for multi-point locks with panic function: latch and bolt must be moved into the lock body when the door is closed with the handle. To ensure this, the cam must be able to turn freely.
  • in motor-driven locks and special escape door locks
  • restrictions possible in combination with other optional equipment

Key with coloured pin:

  • with plastic pin in different colours
  • simplifies the management of the keys
  • can indicate the assignment (e.g. locking authorizations) of the keys
