Medeco Large Format Interchangeable Core

Medeco Large Format Core

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.  


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. Cores are available to fit into rim and mortise  cylinders, key-in-knob and key-in-lever locks, padlocks and bored auxiliary deadlatches and deadbolts.
