BEST BES-1CF71P1626 – Frequently Asked Questions

1) What keyways can I get on the BEST 1CF 7-pin Preferred core?
The 1CF core comes in six Preferred keyways: 1P, 2P, 7P, 8P, 9P and 10P. Pick the keyway that matches the rest of your BEST Preferred system so the core keys into the existing masterkey hierarchy. If you are starting a fresh system, the keyway choice is what locks in your key control going forward, so standardize it across the facility before you buy the first batch.
2) Should I order the BEST 1CF core combinated or uncombinated?
Both are offered. Combinated means the core comes pinned to your keying, and when you order that way you supply the keymark and the marking number so it drops into your existing system. Uncombinated ships unpinned for a locksmith or in-house shop to combinate on site, which is the usual choice if you run your own key records and pinning kit.
3) Will a BEST 1CF Preferred core work in my existing BEST hardware?
Yes. The 1CF Preferred core is backwards compatible with all BEST Peaks systems and with other major brands of locking hardware that accept a BEST small format interchangeable core, so you can swap keying systems or upgrade without replacing the locks themselves. It is a 7-pin brass core built for commercial use.
4) Why choose a BEST Preferred patented core over a standard rim or mortise cylinder?
Different animal. A rim or mortise cylinder like the Schlage 20-021 rim cylinder or the Corbin Russwin 1000 mortise cylinder is a fixed housing you unscrew from the lock to rekey. The BEST 1CF is an interchangeable core: a control key pulls it out of the lock in seconds, so you rekey a whole building by swapping cores instead of pulling hardware. The Preferred system adds patent protection through 2024 for key control, meaning blanks are restricted. That combination is why schools, hospitals and large office portfolios run interchangeable core.
5) I need a full size interchangeable core, not a BEST small format. What should I look at?
The BEST 1CF is a BEST-format interchangeable core and will not drop into a housing prepped for full size IC. For FSIC, the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam, or the 20-057-C FSIC core in C keyway and 643E aged bronze, are the FSIC options. Confirm which format your existing locks are prepped for before ordering either way, since the two are not interchangeable.
6) What is the closest interchangeable core alternative to a BEST 1CF if the hardware takes a full size interchangeable core in a Schlage keyway?
The BEST 1CF is a 7-pin brass Preferred patented interchangeable core supplied in BEST keyways 1P, 2P, 7P, 8P, 9P and 10P. If the opening needs a full size interchangeable core in a Schlage keyway instead, the Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway, finished 643E Aged Bronze. The Schlage 20-057 is the same FSIC rim cylinder function without the keyway called out. Choose by which keying system the building is already on, since a BEST Preferred core and a Schlage C core are not keyed alike to each other.
7) If a lock does not accept an interchangeable core, what mortise cylinder can be used instead of a BEST 1CF?
The 1CF is an interchangeable core, so it only fits hardware built with an IC figure-eight core pocket. For conventional mortise prep, the Corbin Russwin 1000 series mortise cylinder is offered in 1-1/2 inch length with an A02 straight cam, and the Corbin Russwin 1070 is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. Match the cam to the mortise lock body being served.
8) What rim cylinder should be used with an exit device instead of a BEST 1CF core?
Exit devices prepped for a conventional rim cylinder take a rim housing rather than an interchangeable core. The Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam, both supplied with 2 keys. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. The BEST 1CF applies where the device is prepped for an interchangeable core instead.
9) For an aluminum storefront door, is a BEST 1CF core the right part or is something else needed?
Narrow stile aluminum doors normally take a mortise cylinder sized to the stile rather than an interchangeable core. The Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1 with a 1/2 inch minimum door thickness, and the Adams Rite 4024 and 4025 are cylinder pulls made for the Adams Rite MS1847 deadlock and deadlatch, the 4025 being a five pin tumbler pull with through-screws. The BEST 1CF core is for commercial hardware prepped with an interchangeable core pocket.
10) Which cylinder matches a Schlage C keyway building better than a BEST 1CF core?
BEST 1CF cores are cut to BEST keyways 1P, 2P, 7P, 8P, 9P and 10P, so they will not key into a Schlage C system. For a C keyway building, the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, and the Schlage 20-057-C is a full size interchangeable core in the C keyway. Pick the mortise or the core version based on how the existing hardware is prepped.
11) What finishes does the BEST 1CF core come in, and does it need to match the lock?
Four finishes: 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, and 626 satin chrome. Only the core face shows once it is installed, so match it to the lockset trim on the door. In a mixed building, most buyers standardize on 626 satin chrome for the bright openings and 613 where the trim is dark.
12) Can the BEST 1CF core be masterkeyed across a building?
Yes, masterkeying is what the Preferred system is built around. The 7-pin configuration gives the depth needed for multiple levels of masterkeying, and key duplication uses standard key cutting equipment, so your local shop can cut to the system without special machinery. BEST publishes the Preferred keying detail in its BA-3420 Preferred Keying document.
13) I manage a portfolio and want one core I can use on knobs, levers and exit device trim. Does this do that?
That is the point of the format. One 1CF core type serves every BEST-prepped opening in the building, so tenant turnover means pulling and repinning a core rather than changing a lockset. Order all cores in the same keyway out of the six Preferred keyways so any core can go in any door. Compare that to brand-specific replacement cylinders like the Kaba Ilco 1579 for Sargent knobs and levers, where each lock family needs its own part.
14) Can a Corbin Russwin 1080 LFIC cylinder be used in place of a BEST 1CF core?
No, they are different core formats. The BEST 1CF is a 7-pin full size style Preferred patented interchangeable core. The Corbin Russwin 1080 is a 1-1/2 inch large format interchangeable core mortise cylinder, 6-pin, built for Schlage L9000 mortise locks with an A01 cam. The 1080 is a housing plus cylinder assembly for a mortise prep, not a drop-in core for BEST-prepped hardware.
15) For rekeying key-in-knob and lever locks without an IC core pocket, what replaces a BEST 1CF?
Use a conventional key-in-lever cylinder. The Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1599 is a key-in-knob replacement cylinder, and the 1579 is a knob and lever cylinder made for Sargent hardware. Falcon offers the A23161-05 G key-in-lever cylinder in the RU/T series 6-pin G keyway, keyed different with 2 cut keys. The BEST 1CF is the choice only where the knob or lever is built to take an interchangeable core.
16) What is the difference between a BEST 1CF core and a Medeco retrofit cylinder for a residential handleset or deadbolt?
The BEST 1CF is a commercial 7-pin brass interchangeable core in BEST Preferred keyways that swaps out of an IC pocket without removing the lock. The Medeco retrofit cylinders address residential-style hardware instead: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. They are not interchangeable with BEST core prep.
17) For a deadbolt that needs rekeying, can a BEST 1CF core be used or is a deadbolt cylinder required?
If the deadbolt is prepped for an interchangeable core, the BEST 1CF drops in and can be combinated or supplied uncombinated for shop keying. If it is a conventional deadbolt, the Kaba Ilco 1549 is a key-in-deadbolt cylinder for that function, and the Adams Rite 4026 is a five pin tumbler cylinder pull for the 5017 wood door deadlock and deadlatch.
18) Is the BEST 1CF core suitable for a hospital or school, or is it a residential part?
Commercial. The 1CF Preferred core is a commercial door hardware part used in office buildings, schools, healthcare facilities, government and municipal buildings, industrial and warehouse sites, multi-tenant residential and retail. Brass body, 7-pin, intended for the repeated rekeying cycle those facilities run.
19) Is a BEST 1CF core or an Emtek CY4 the right cylinder for decorative residential trim?
The Emtek CY4 cylinder is sold as a single replacement cylinder for Emtek hardware, and Medeco offers the 1065244, a 5-pin rim lazy motion cylinder with an Emtek tailpiece, for that same family. The BEST 1CF is a commercial 7-pin interchangeable core offered in 606 Satin Brass, 612 Satin Bronze, 613 Satin Bronze Oil-Rubbed and 626 Satin Chrome, for hardware built with an IC core pocket.
