IKON WSW

The WSW is a hybrid lock made by the German company IKON.

Principles of operation


The WSW key is bitted on the sides and edges of the blade and is reversible. It has a row of six dimple cuts matching six pin-tumblers at the top of the keyway. There are three different heights for these key pins. They are T-shaped and rest in matching chambers drilled in the core. The brass driver pins for this row of pins are a mix of three standard pins and three spool security pins.

The WSW also features one or two sidebars, depending on the model. The interior model has five side pins with a single sidebar. The exterior model adds either two or five additional side pins connected to a second sidebar. The steel side pins are spring-biased and control the sidebar(s) of the lock.

To open the lock, all six key pins and all side pins must be aligned at the shear line. (See also Pin-tumbler, Principles of operation)

Disassembly instructions
The WSW is disassembled in the same way as a traditional pin-tumbler cylinder, though extra attention must be paid to the sidebar and side pins during disassembly.


 * 1) Remove the c-clip holding the core in place
 * 2) Insert the key and turn the plug 30-45 degrees.
 * 3) Withdraw the plug from the cylinder, being careful to retain the sidebar and side pins.
 * 4) (A plug follower and core shims are strongly recommended)
