Lock Design	Pin-tumbler, Sidebar
Year(s) Produced	2005 - Present

The BiLevel (or Medeco³ BiLevel) is a pin-tumbler lock manufactured by Medeco. Unlike Medeco's other systems which use axial rotation, the BiLevel uses pin-tumblers and a traditional shear line as the primary locking mechanisms. Medeco advertises the BiLevel for key control rather than security against picking and destructive entry.

The BiLevel is a lower security form of the Medeco M3. It is easily identified by the "m³B" logo to the left of the keyway.

Principles of operation

See also Pin-tumbler (Principles of Operation)

Unlike Medeco's other systems that use axial rotation to properly position pin-tumblers with sidebar legs, the BiLevel uses a sidebar that only interfaces with the M3 slider component. The BiLevel is marketted as a lower security (and cheaper) version of the M3 that can be integrated into existing M3 systems.

Disassembly Instructions

The BiLevel can be disassembled in the same way as a standard pin-tumbler mechanism with consideration for the sidebar and slider components.

1. Remove the cam or C-clip.
2. Insert the key and turn the plug 45-90 degrees.
3. Withdraw the plug from the cylinder. (A plug follower is recommended)

OR

1. Remove the chamber casings and take out each pin-stack individually
2. Remove the cam or C-clip.
3. Withdraw the plug from the cylinder.
