Medeco BiLevel

=Medeco BiLevel=

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.

Vulnerabilities
The Medeco BiLevel may be vulnerable to one or more of the following:


 * Lockpicking
 * Key bumping
 * Impressioning
 * Decoding
