Beyond One-Size-Fits-All: Medeco SFIC Security Continuum

July 2, 2018
Three options: MedecoB value-based non-patented system, Medeco X4 patent protected key control solution and Medeco XT, digital SFIC

The universal size and format of Small Format Interchangeable Core (SFIC) has spawned a plethora of options from various manufacturers worldwide. There are many SFIC products on the market filling the basic need of replacing worn or disabled SFIC. What has been missing is a range of products to custom-fit an operation’s function, security protocol and layout, solving their unique security challenges.

Medeco Security Locks, an ASSA ABLOY N.A. Group company based in Salem, VA, has developed a suite of SFIC products that address end users’ needs, rather than simply offer a one-size-fits-all solution. The Medeco SFIC Security Continuum is a range of cylinders beginning with a quality un-patented solution for value and convenience, to a patented key control SFIC with expanded master keying capabilities, to a digital SFIC offering for high accountability and real-time access control.

Included in the Medeco SFIC Continuum: MedecoB for value and convenience; Medeco X4, a patent protected key control solution with one of the largest master key capabilities on the market; and Medeco XT, which brings scheduling and audit capabilities along with digital master keying into the SFIC realm.

There are a number of factors any facility management team must consider when choosing the correct SFIC solution for their needs. A challenge for many SFIC owners is to simply get their key management system under control. With the flexibility of the Medeco SFIC Security Continuum, end users can greatly improve their security, as well as save money in the long run, simply by choosing the right SFIC product.  

An examination of the Medeco SFIC Security Continuum can help determine the right SFIC option for the customer.


MedecoB, the entry group to Medeco’s SFIC Continuum, offers an affordable alternative for end-users seeking industry standard unpatented SFIC keyways. MedecoB integrates into existing legacy systems, allowing for seamless incorporation and ultimately cost savings. With a highly competitive price point, MedecoB saves organizations money while offering U.S. made quality in 27 industry standard keyways: 1C, 1D, AB, BB, CB, DB, EB, FB, GB, HB, JB, KB, LB, MB, QB, RB, TA, TB, TC, TD, TE, WA, WB, WC, WG, WH, and WY.

Medeco X4

Medeco X4 SFIC is the ideal security upgrade for facilities seeking to regain control of their key systems. Medeco X4 provides peace of mind, with patent protected key control until 2030, preventing unauthorized key duplication and restricting the production of aftermarket key blanks. Medeco X4 key blanks are only distributed to authorized dealers or distributors and are uniquely marked for identification for each dealer or end user, ensuring integrity of the system.

Medeco X4 has one of the largest master keying capabilities for SFIC on the market, offering even the largest operations room to grow. Available in SFIC, LFIC and most conventional cylinder formats, X4 easily retrofits into existing door hardware, reducing installation time and overall costs. Medeco X4 is the ideal choice for facility managers seeking to tie multiple lock types from varied manufacturers into a one key system, providing convenience and efficiency.  

Medeco XT

Medeco XT is access control disguised as a Small Format Interchangeable Core. Simply by installing XT SFIC into existing hardware, the door to a vulnerable area gains controlled access, complete with scheduling and audit, and effective system management. No hard wiring or changes to the door or hardware are needed to incorporate XT SFIC. Managers can provide access control on as many or few doors as necessary, saving significant costs over a blanket traditional electronic access control system.

All power to operate the Medeco XT cylinder is stored in its unique Slim Line Key. It operates with a rechargeable battery, which carries up to 1,800 openings per charge. Medeco XT keys are programmed to open specific locks on a designated schedule and expirations can be set to completely disable keys, allowing reprogramming for future users.

The Medeco XT SFIC fits all standard hardware prepped for SFIC. It is built for indoor and outdoor use with stainless steel shell construction. Medeco XT is also available in a variety of other retrofit cylinder formats, including cam locks and padlocks, to allow audit and scheduling on virtually any opening without the expense of traditional EAC.

Choosing the Right SFIC Solution

Medeco’s smart SFIC Security Continuum was developed to offer the customer relevant choices when it comes to properly securing their facility. From mechanical keys to intelligent openings, the array of solutions along the continuum pairs the appropriate locking technology to the specific requirements and security risks of each facility. Careful consideration of each opening based on usage requirements allows proper selection of control, enhancing the security of a facility and keeping costs in line.

The Medeco SFIC Security Continuum provides clear choices for end users who are looking for value, key control, accountability or a combination of the three. Many SFIC-based facilities have been a victim of inconsistent security, lack of key control, loss of revenue, and general security system neglect or mismanagement. Providing a choice of integrated and intelligent SFIC products that fit specific security needs and price point, not one-size-fits-all, is the future of SFIC.
