The use of a [[Plug_follower#Pinning_shoe|pinning shoe]] is the preferred method for disassembling a double euro cylinder. Another method is to use a [[Plug follower|segmented follower]]. The c-clips retaining both cores must first be removed and then both cores can be pulled out slightly in order to remove the center cam. One core should be rotated 30-45 degrees either clockwise or counter-clockwise -- once the cam is removed. This allows the core to be removed without driver pins entering gaps for the cam clutch. At that point, a segmented follower can be used to remove the core.

A [[Plug_follower#Pinning_shoe|pinning shoe]], used with a modified key, is a common method for removing the plug from a Euro profile cylinder.

This allows the plug to be removed while preventing the driver pins and springs from escaping the cylinder housing. As an alternative method, a [[Plug follower|segmented plug follower]] could be used.


Locks not intended for installation and use can be disassembled in a quick but destructive procedure. The cylinder housing itself can be cut in the middle using a hacksaw or grinder. The cam will no longer be held in place and can be removed. The resulting two cut half euro cylinders can then be disassembled as outlined above.

The TK5 is a pin-tumbler lock made by the German company IKON. The key bow bears the mark of Bo Widén.

Principles of operation

The TK5 cylinder contains five traditional pin-tumbler stacks. It also utilizes four spring-biased finger pins, that must be lifted and rotated to align with the sidebar, in order for the plug to turn.

Disassembly instructions

The IKON TK5 is disassembled much like other euro profile cylinders, with some care for the sidebar and finger pins during disassembly.

The IKON TK5 has a multiple component cam piece that is disassembled before the plug can be removed. To access the cam components, rotate the cam until a hole in the side of the cam is revealed, and insert a tool to press the spring-biased retainer inside. At the same time, pry away the side plates of the cam. The inner two plates can then be removed, allowing the plug to slide through the cylinder housing.

A pinning shoe, used with a modified key, is a common method for removing the plug from a Euro profile cylinder. One plug is rotated 180 degrees either clockwise or counter-clockwise, and the pin retainer inserted into the edge of the keyway. This allows the plug to be removed while preventing the driver pins and springs from escaping the cylinder housing. As an alternative method, a segmented plug follower could be used.
