Medeco 337B01 7 Pin Small Format Interchangeable Core (SFIC) — Alphabet, T & W Series Keyways

The Medeco B Small Format Interchangeable Core (SFIC) is an economic and efficient solution for commercial rekeying needs, engineered to retrofit existing systems and significantly reduce installation time. Available in a 7 pin format and compatible with established industry standard Alphabet, T Series, and W Series keyways, this SFIC is built from solid brass construction for excellent durability. The reinforced sleeve design provides added strength, and compatibility with Schlage SFIC housings makes it a versatile key control upgrade for a wide range of commercial facilities. Rated Grade 1 and Heavy Duty, this core is suited for demanding commercial door hardware applications.

Key Features

  • 7 Pin Format: Available in 7 pin configuration for enhanced key combination capacity and security in commercial applications.
  • Solid Brass Construction: Solid brass body delivers excellent durability and long-term performance in heavy-duty commercial environments.
  • Reinforced Sleeve Design: The reinforced sleeve provides added strength and structural integrity for extended service life.
  • Spool-Shaped Top and Bottom Pins: Spool-shaped top and bottom pins add a meaningful measure of pick resistance to enhance security.
  • Solid Nickel Silver Bottom Pins: Solid nickel silver bottom pins increase wear resistance for reliable, long-lasting operation.
  • Quick Core Exchange Without Disassembly: Cylinders can be quickly and easily changed by non-technical personnel using a special control key — the core is removed from the lock housing and a new combination core inserted, effectively rekeying the lock without taking it apart, eliminating the need for outside service personnel.
  • Individual Pin Chamber Caps: Individual pin chamber caps provide ease of servicing and simplified maintenance in the field.
  • Flexible Keying Options: Locks can be keyed alike, keyed different, or master keyed depending on specific security requirements.
  • Wide Finish Selection: Available in 14 finishes including Bright Brass (05), Satin Brass (06), Antique Brass (09), Satin Brass Blackened (10), Bright Bronze (11), Satin Bronze (12), Oil Rubbed Bronze (13), Bright Nickel (18), Satin Nickel (19), Antique Nickel (20), Black (22), Dark Bronze (24), Bright Chrome (25), and Satin Chrome (26).

Medeco 337B010-06-A1CS – Frequently Asked Questions

1) Will a Medeco 337B01 SFIC core drop into my existing Best or Schlage small format housings?
Yes. The 337B01 is a small format interchangeable core built to the industry standard SFIC figure-eight envelope, and Schlage compatibility is called out directly in the spec data. It is offered across Best keyways (AB through WY, including the T and W families) and Arrow 1C and 1D keyways, so if your existing housings, padlocks, mortise cylinder shells and rim housings take a standard SFIC, this core seats in them. You still need a control key cut to the core's control sequence to pull and replace it.
2) How do I pick the right keyway for a Medeco B 7 pin SFIC core?
Match the keyway to the system already in the building, not to preference. The 337B01 is ordered in one of 27 keyway designations: Arrow 1C and 1D, and the Best family 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. If your site is already running a Best A2 style master key system on, say, the C keyway, you order CB so the new cores fall under the existing top master. Ordering the wrong letter gives you a core no existing key will enter.
3) Is this a 6 pin or 7 pin core, and does that matter for my existing keys?
It is 7 pin. That matters: a 7 pin core will not accept a 6 pin key from a different system, and 7 pin gives you a deeper masterkeying tree, which is why facilities with large multi-level master systems specify it. If the building's existing cores are 6 pin, mixing in 7 pin cores means the keying schedule has to be worked out by whoever maintains your system before the cores are pinned.
4) Can property staff rekey these without pulling the lock apart?
That's the point of an interchangeable core. With a control key, a non-technical staff member rotates the core out of the housing and drops a new combination core in, which rekeys that opening in seconds without disassembling the lockset or removing it from the door. For a property manager turning units or dealing with a lost key, it means no service call and no downtime on the opening.
5) What does Sub-Assembled mean when ordering the Medeco 337B01 core?
Sub-assembled means the core ships built but not combinated to a finished key change. It is the way a locksmith or an in-house shop buys them when they intend to pin the core to their own master key system. If you expected a core that arrives keyed and ready to hand to a tenant with operating keys, that is a different order: the pinning has to be specified and done to your keying schedule.
6) Is the Medeco 337B01 core tough enough for a high traffic commercial entrance?
It's rated Grade 1 and Heavy Duty, and it's a commercial product, which is the top ANSI/BHMA performance tier for door hardware. The body is solid brass with a reinforced sleeve, and the bottom pins are solid nickel silver for wear resistance. For school corridors, hospital doors, or a retail main entry seeing hundreds of cycles a day, that is the specification level you want.
7) How is a Medeco B core different from a standard brass SFIC core on pick resistance?
The Medeco B technology core uses spool-shaped top and bottom pins, which bind against the shear line under picking pressure and add real resistance compared with plain straight pins. Bottom pins are solid nickel silver, so they hold their profile after long service instead of wearing round. Individual pin chamber caps mean a shop can service a single chamber in the field rather than replacing the core.
8) Can I key these alike across a building, or master key them into an existing system?
Both. The 337B01 cores can be keyed alike, keyed different, or master keyed. For a multi-tenant or mixed-use property that usually means keyed different at the unit doors with a building master above them, and keyed alike on common mechanical and janitorial doors. Because they ship sub-assembled, the keying schedule is worked out first and the cores pinned to it.
9) What finishes does the Medeco 337B01 7 pin SFIC come in, and will it match my existing hardware?
Two finishes are orderable: 606 Satin Brass and 626 Satin Chrome. 626 is the standard commercial finish and will sit correctly next to the satin chrome levers and exit devices on most office, school and healthcare openings; 606 is the match where the building is running satin brass trim. Only the visible core face shows once installed, so matching the surrounding trim is what matters.
10) Does the plain face on this SFIC mean it takes no keyway insert or logo plug?
Plain face is the standard, unbranded core face, with no stamped logo or decorative face plate. Locksmiths and integrators specify it when they do not want a manufacturer mark showing on the opening, or when the site standardizes all cores to one look regardless of who supplies them. Function is identical to a marked face core.
11) Do I need a Medeco dealer contract to buy these cores?
No contract is required for Medeco B Small Format Interchangeable Cores. They are sold through Medeco and authorized distributors, which is different from Medeco's restricted high security lines. That makes them straightforward for a locksmith shop, an integrator, or an institutional MRO buyer to purchase and stock.
