Medeco³ LFIC

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.

Benefits:

  • Cylinders can quickly and easily be changed by non-technical personal by using a special control key which will remove the core from the lock housing. A core with a new combination can then be inserted and the lock will then effectively be "re-keyed". All of this can be done without having to take the lock apart which reduces the expense of calling outside service personnel to perform routine lock "re-keys".
  • UL437 listing provides assurance that cylinders meet universal standards for drill and pick resistance and stand up to other types of forced attack.
  • The 31 Series interchangeable core has a control/locking lug positioned at the back of the cylinder. An extra long key activates the control/locking lug. This eliminates the need for build up or control pins thus simplifying pinning. It also allows the introduction of interchangeable core cylinders into existing master key systems that were not designed to accommodate interchangeable core pinning.
  • The 32 series interchangeable core cylinders have the control/locking lug positioned at the middle of the core. This provides additional protection against dent puller attacks.
  • The 32 series uses coordinated cuts between the operating keys and the control keys which eliminates the need for build up or control pins and simplifies pinning.
  • All Medeco® cylinders are constructed of durable machined brass components, designed to last the life of your equipment.
  • Patented Medeco³ keys may only be duplicated by Medeco® or an authorized Medeco®service outlet, and only at your request.
  • Locks can be keyed alike, keyed different, or master keyed depending on your specific needs.

Applications:

  • 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.
