Medeco X4

An Economical and Efficient Keying Solution


All facilities need patented key control to effectively secure exterior and interior openings. This strength of integrity allows security managers to have peace of mind when it comes to managing the system. Unfortunately, instituting a new key system is not always easy—or economical.

Medeco X4 is the most economical and efficient solution. It has one of the largest master key capabilities on the market. This allows facility managers to tie everything together under one key for ease, convenience and efficiency. Additionally, Medeco X4 easily retrofits into existing systems so installation time is minimal.

Medeco X4 is the perfect security upgrade for small format interchangeable core (SFIC) installations for Best-style, Prox and iClass systems. In addition to SFIC cylinders, Medeco X4 is also available in many other styles of retrofit cylinders, and can be keyed into a single system.

  • Patented Key Control - Protects against unauthorized duplication of your keys.
  • Uses Existing Hardware - Can be masterkeyed into a system containing Medeco BiLevel, and is available in a large selection of retrofit cylinder formats, including SFIC, that can all be keyed into a single system.
  • Can Be Masterkeyed - Available in SFIC and other retrofit cylinder formats that can be masterkeyed together, eliminating the need to replace your existing hardware.
  • Quick Change Cores - Medeco X4 Small Format Interchangeable Cores provide quick and easy cylinder changes in the event keys are lost or stolen.
