BEST 7CS-6-J-1-626 – Frequently Asked Questions

1) Does the BEST 7CS core come keyed, or do I need a locksmith?
It ships uncombinated with a blank core face, meaning no pins are set and no keys come with it. A locksmith or an in-house key shop has to combinate it to your system before it will operate. If you do not pin cores yourself, budget for that step. Buyers who want a cylinder that works out of the box are better off with a factory-keyed cylinder such as the Falcon A23161-05 G, a 6-pin G keyway key-in-lever cylinder supplied keyed different with two cut keys.
2) Is a BEST SFIC core the same thing as a full size interchangeable core?
No, and they are not interchangeable. The 7CS is small format (SFIC), the figure-eight core BEST hardware is prepped for. Full size interchangeable core (FSIC) is a larger, different housing and needs FSIC-prepped hardware. If your locks are FSIC, look at a Schlage FSIC core such as the 20-057-C in C keyway, or the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam. Ordering an SFIC core for an FSIC prep, or the reverse, means the core will not seat.
3) I need to add a keyed opening to an existing BEST master key system. What do I order?
Order 7CS cores in the same keyway your system runs and in the matching pin count, then have them combinated to the existing master. The keyway options run D, E, F, G, H, J, K, L, and M among the 26 available, in both 6-pin and 7-pin, in 606 satin brass or 626 satin chrome. Note the keyway letter stamped on one of your current keys or cores and order to it; a core in the wrong keyway family will physically reject your key even if the cuts are right.
4) Can I put a BEST 7CS core into a Schlage, Corbin Russwin, or Adams Rite lock?
Only where that lock is prepped for a small format interchangeable core. SFIC is a standard figure-eight format, so hardware from other makers built with an SFIC housing accepts it, but a lock built for a conventional cylinder does not. Adams Rite storefront deadlocks, for example, take a mortise cylinder like the Adams Rite 4036 five-pin Grade 1, or a cylinder pull such as the 4025 for the MS1847 deadlock, not an interchangeable core. Check the lock body's prep before ordering cores.
5) Is the Schlage 20-057 interchangeable core a substitute for a BEST 7CS small format core?
No. The BEST 7CS is a small format interchangeable core (SFIC), while the Schlage Commercial 20-057 and the 20-057-C are full size interchangeable core (FSIC) cylinders. SFIC and FSIC cores use different core bodies and different housings, so one does not drop into the other's prep. The 20-057 is supplied as a rim cylinder with a convertible tailpiece cam, and the 20-057-C is an FSIC core in C keyway with a 643E Aged Bronze finish. Order the 7CS when the existing hardware is SFIC-prepped and you intend to key it yourself, since the 7CS arrives uncombinated with a blank core face for locksmith keying.
6) What should I use instead of a BEST 7CS core on an exit device that needs a rim cylinder?
A 7CS small format core has no tailpiece of its own, so on a rim application it needs an SFIC rim housing. If the opening is not SFIC-prepped, a one-piece rim cylinder covers it directly: the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam, and the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. Match the tailpiece orientation and length to what the device chassis accepts. Choose the 7CS route when the building is already keyed on a small format system and cores need to be swapped without pulling the device apart.
7) For a mortise lock, do I order the BEST 7CS core or a mortise cylinder?
A mortise lock needs a threaded mortise cylinder body with a cam; the 7CS is the core that drops into an SFIC-prepped housing, not a mortise cylinder by itself. If the lock takes a conventional mortise cylinder, the Corbin Russwin 1000 Grade 1 series mortise cylinder is 1-1/2 inch with an A02 straight cam, the Corbin Russwin 1070 Grade 1 series mortise housing is 1-1/4 inch 6-pin with an A01 cloverleaf cam, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway. If the specification calls for an interchangeable core mortise setup, the Corbin Russwin 1080 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, for Schlage L9000 mortise locks with an A01 Schlage L cam. The 7CS applies where the mortise housing is small format prepped and you are keying to an existing BEST-style keyway such as D, G, J, K, L or M.
8) My keys are cut to a Schlage C keyway. Will a BEST 7CS core work with them?
No. The 7CS is offered in keyways D, E, F, G, H, J, K, L and M among its 26 keyway options, and a core must be ordered in the keyway the existing keys are cut to. For a system already on Schlage C, the Detex MC65 is a mortise cylinder in Schlage C keyway and the Schlage 20-057-C is a full size interchangeable core in C keyway. Identify the keyway stamped on the existing key bow or pull an existing core before ordering, since the 7CS ships uncombinated and must be pinned to the system it joins.
9) What is the closest alternative if I want an interchangeable core but my hardware is not BEST-prepped?
Interchangeable core comes in two sizes and they are not cross-compatible. The BEST 7CS is the small format version, brass body and face, 6-pin or 7-pin, in 606 Satin Brass, 613 Oil-rubbed Bronze and 626 Satin Chrome. For full size interchangeable core hardware, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and the 20-057-C is an FSIC core in C keyway, 643E Aged Bronze. For large format interchangeable core in a mortise lock, the Corbin Russwin 1080 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, for Schlage L9000 mortise locks. Confirm which core size the lock housing accepts, then order to that size.
10) What is the difference between 6-pin and 7-pin on a BEST SFIC core, and which should I order?
Both configurations are offered on the 7CS. The choice is dictated by the master key system already in place, not by the door. A 7-pin system gives more room for master key levels in a large facility; a 6-pin system is the more common commercial setup. Mixing pin counts inside one system breaks the keying, so order to match whatever the rest of your cores are.
11) Why would I use interchangeable cores instead of standard mortise or rim cylinders in my building?
Turnover. With SFIC, rekeying a door is pulling one core with a control key and dropping in another, about ten seconds, no tools, no removing the lock from the door. Property managers and facility teams with tenant churn or lost keys keep spare combinated cores on a shelf and swap on the spot. A conventional cylinder such as the Corbin Russwin 1000 Grade 1 mortise cylinder in 1-1/2 inch length with an A02 straight cam has to be taken out of the lock and repinned instead. If you rekey once a decade, conventional is simpler and there is no control key to manage.
12) I need a replacement cylinder for a key-in-knob or key-in-lever lock. Is the 7CS core the right part?
Only if the lockset is SFIC-prepped. The 7CS is a replacement core for interchangeable core hardware, not a drop-in for a conventional knob or lever. For conventional key-in-knob and lever locks, a replacement cylinder is the right part: the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the 1579 is the version for Sargent, and the 1599 is a key-in-knob replacement cylinder.
13) I just need to rekey a key-in-knob or key-in-lever lockset, not run a core system. What is simpler than a 7CS?
The 7CS is built for small format interchangeable core systems, which means an SFIC-prepped lockset and a locksmith to combinate it, since it ships uncombinated. For a plain replacement cylinder in a key-in-knob or key-in-lever set, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent, and the 1599 is a key-in-knob replacement cylinder. For a keyed deadbolt, the Kaba Ilco 1549 is a key-in-deadbolt cylinder. A Falcon A23161-05 G is a key-in-lever cylinder for the RU/T series, 6-pin G keyway, keyed different with two cut keys. The 7CS earns its place when cores must be pulled and replaced across many doors on one master key system.
14) Can a BEST 7CS core be used on an aluminum storefront narrow stile door?
On a narrow stile aluminum door the cylinder is dictated by the deadlock, not by the core format, so a 7CS only applies if the device is prepped for a small format core. For Adams Rite narrow stile hardware, the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both designed for the Adams Rite MS1847 deadlock or deadlatch, and the 4036 mortise cylinder is a Grade 1 five-pin cylinder with a 1/2 inch minimum door thickness. For a wood door deadlock, the Adams Rite 4026 five pin tumbler cylinder pull is designed for the 5017 wood door deadlock or deadlatch. Confirm which device is in the stile before choosing between those and a small format core.
15) Does the BEST 7CS fit a residential handleset or deadbolt?
The 7CS is a commercial small format interchangeable core and needs SFIC-prepped commercial hardware; residential handlesets and deadbolts take a rim type or retrofit cylinder sized to that lock. The Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder. For an Emtek set, the Emtek CY4 cylinder is sold each. Reserve the 7CS for commercial openings running a small format core system.
16) I need a 7-pin core for a deeper master key system. Do the comparable cylinders offer that?
The BEST 7CS is available in both 6-pin and 7-pin configurations, which is what gives a master key system the extra level of keying depth. Among the comparable cylinders, the 6-pin configurations are the Corbin Russwin 3070 rim cylinder housing, the Corbin Russwin 1070 mortise housing, the Corbin Russwin 1080 LFIC mortise cylinder, the Detex MC65 mortise cylinder, the Falcon A23161-05 G key in lever cylinder, the Schlage 20-021 and 20-022 rim cylinders, and the Schlage 20-057 FSIC rim cylinder, while the Adams Rite 4025, 4026 and 4036 and the Medeco 1065140, 1065244 and 1075127 are five-pin. If the keying schedule calls for 7 pins, order the 7-pin 7CS in the keyway that matches the existing system.
17) What finishes does the BEST 7CS core come in, and will it match my other door hardware?
Three finishes: 606 satin brass, 613 oil-rubbed bronze, and 626 satin chrome. Only the core face shows once installed, so 626 satin chrome is the one that blends with the satin chrome and brushed stainless lever trim used on most commercial openings, and 606 pairs with satin brass hardware. On the current run of cores, the 606 and 626 faces are what you can order against any of the 26 keyways in either 6- or 7-pin.
18) What material is the BEST 7CS core, and will it hold up in an exterior or wash-down opening?
Body and face are both brass, which resists corrosion and is the standard material for commercial cylinder work. That covers exterior entrances, parking structures, and humid back-of-house areas. The 7CS is a commercial-duty part, used in offices, schools, healthcare, government buildings, multi-tenant residential, warehouses, and retail.
