Medeco® Large Format Interchangeable Core (LFIC) cylinders are designed so that cores can quickly and easily be changed by non-technical personnel by using a special control key. Locks can, in effect, be “rekeyed” without having a working knowledge of the lock or without having to take the lock apart.

Medeco® LFIC cylinders are available in a variety of different sizes, formats and security levels. Cores are available to fit into rim and mortise cylinders, key-in-knob locks, padlocks and bored auxiliary deadlatches and deadbolts. The Medeco® 32 Series LFIC’s are UL437 listed and provide drill and pick resistance and those that incorporate the Medeco³ design offer utility patented control.

The Medeco® 31 Series is designed to retrofit the Yale® LFIC  mortise housings, rim, key-in-knob and padlock bodies and the 32 Series fits Medeco® rim and mortise cylinder housings, padlock bodies, Maxum deadbolts, Embassy knob and lever cylindrical locksets, and Simplex Unican.

Medeco® LFIC cylinders can be ordered with a variety of different cylinder technologies, including the features below for Medeco³.
