BEST BES-1CB6B116263856 – Frequently Asked Questions

1) Will a BEST Peaks 1CB core drop into my existing BEST interchangeable core locks?
The Peaks 1CB 150 Series core is built for traditional BEST interchangeable core applications, so it goes into BEST IC hardware the same way any BEST small format core does: turn the control key, pull the old core, drop the new one in. No disassembly of the lock. It operates cylindrical locks, padlocks, deadbolts, and cabinet locks. What it will not do is give you keys off the shelf. Peaks is a patented keying system and the keys come only through authorized BEST distributors, so you're switching that opening onto a Peaks key system, not matching an existing standard BEST key.
2) Do I order the 6-pin or the 7-pin BEST Peaks core?
Match whatever your existing BEST system is keyed to. The Peaks 1CB comes in 6-pin and 7-pin, in brass core styles for each. Facilities running a 7-pin BEST masterkey system need the 7-pin to sit in the same key hierarchy; a 6-pin core in a 7-pin system breaks the masterkeying. If you're starting fresh on a building, 7-pin gives more room for master and grand master levels as the system grows. Both sizes fit the same BEST IC housings.
3) What is the difference between ordering a Peaks core combinated and uncombinated?
Combinated means the core arrives pinned to a key combination you specify. When you order that way, give the Keymark and the Marking Number from your existing BEST system so the core lands in the right place in your key hierarchy. Uncombinated ships unpinned, for a locksmith or an in-house shop that pins its own cores. Property managers and facility staff without a pinning kit want combinated. Locksmiths maintaining a system usually take uncombinated.
4) I need a replacement cylinder but my locks are Schlage, not BEST. Will a Peaks core work?
No. The Peaks 1CB is a BEST interchangeable core and it fits BEST IC hardware only. For Schlage full size interchangeable core openings, the Schlage Commercial 20-057 FSIC rim cylinder or the 20-057-C FSIC core in C keyway with 643E aged bronze finish is the right family. For a Schlage L9000 mortise lock taking a large format IC, the Corbin Russwin 1080 Series 1-1/2 inch LFIC mortise cylinder with the A01 Schlage L cam is made for that lock.
5) What is the equivalent to a BEST Peaks 1CB core if the facility is standardized on Schlage instead of BEST?
The BEST Peaks 1CB 150 Series is a small format interchangeable core that drops into BEST interchangeable core hardware and is offered in 6-pin and 7-pin sizes across B1, B2, B3, B6, B7 and B10 keyways. On the Schlage side, the interchangeable core equivalent is the Schlage 20-057-C, a full size interchangeable core in the Schlage C keyway with a 643E Aged Bronze finish. The two are not cross-compatible: a full size core needs FSIC-prepped housings and a figure-eight core cavity, while the Peaks 1CB fits BEST small format cavities, so the choice follows what the existing housings on the doors are prepped for.
6) I need an interchangeable core in an exit device rim housing, not a lock. Is the Peaks 1CB the right part?
The Peaks 1CB 150 Series core operates cylindrical locks, padlocks, deadbolts and cabinet locks, and it seats in a BEST interchangeable core housing rather than mounting to the device itself. For a rim application where the housing is part of the order, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and two keys, so it supplies both the rim housing and the interchangeable core cavity in one part. Order the 1CB when the rim housing is already in the door and only the core is being replaced or rekeyed.
7) What should I use instead of a Peaks 1CB core on a mortise lock body?
A Peaks 1CB core is a small format interchangeable core and needs a mortise housing to carry it into a mortise lock case; the core alone will not thread into the lock. For a mortise opening ordered complete, the Corbin Russwin 1080 in 1-1/2 inch is a 6-pin LFIC mortise cylinder built for Schlage L9000 mortise locks with an A01 cloverleaf cam, and the Corbin Russwin 1000 in 1-1/2 inch is a Grade 1 mortise cylinder with an A02 straight cam. Cam style has to match the mortise lock case, which is why those two differ.
8) Which cylinders look like a substitute for a BEST Peaks 1CB core but will not work in its place?
Several parts read as cylinders and are not interchangeable with a Peaks 1CB. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece and the Corbin Russwin 1070 in 1-1/4 inch is a 6-pin mortise housing with an A01 cloverleaf cam; both are housings, not cores. The Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, a fixed cylinder on a different keyway family than the B1 through B10 Peaks keyways. The Adams Rite 4026 is a five pin tumbler cylinder pull for the Adams Rite 5017 wood door deadlock, which is a pull assembly for one specific deadlock rather than a core.
9) For an aluminum storefront deadlock, do I order a Peaks 1CB core or something else?
A storefront deadlock takes a cylinder sized and cammed for that specific lock, not a bare interchangeable core. The Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security and a 1/2 inch minimum door thickness, and the Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both made for the Adams Rite MS1847 deadlock and deadlatch. Reserve the Peaks 1CB 150 Series for openings whose hardware is prepped to accept a BEST interchangeable core.
10) Can I upgrade later from Peaks to another BEST key system without replacing the hardware?
Yes. The 150 Series core is compatible with BEST CORMAX or BEST Preferred components, so a facility that starts on Peaks can move up later without pulling out the locks. That matters on a phased rollout: you standardize the hardware now and change the core platform later as the security requirement changes.
11) Why can't I just buy Peaks keys and blanks anywhere?
That restriction is the point of the product. Peaks is a patented keying system, and the keys are distributed only through authorized BEST distributors. Nobody walks into a hardware store and duplicates a key to your building. For schools, healthcare, government buildings, and multi-tenant properties, that's the difference between a key system you control and one that quietly spreads copies for years. The trade-off is process: every additional key goes through the distributor and your key records, not a counter machine.
12) Should I use an interchangeable core or a conventional keyed cylinder for a building I have to rekey often?
Interchangeable core, every time, if turnover is the problem. With the Peaks 1CB you change a tenant or a terminated employee out of the system by pulling one core with a control key and dropping in another, in under a minute per door, with no tools and no disassembly. A conventional cylinder like the Corbin Russwin 1000 Series 1-1/2 inch mortise cylinder or the Kaba Ilco 1599 key-in-knob replacement cylinder has to be pulled from the lock and repinned or replaced. Conventional makes sense on a handful of doors that rarely change. IC pays for itself across a building with regular turnover.
13) Can I put the same Peaks core in my padlocks and my door locks so one key runs everything?
Yes, that's the main reason facilities go this route. The 150 Series core operates cylindrical locks, padlocks, deadbolts, and cabinet locks, so a maintenance tech carries one key for the mechanical room door, the gate padlock, and the tool cabinet. Order the same keyway and the same core size across all of them and keep every opening in one hierarchy.
14) Is there a simpler cylinder than a Peaks 1CB for a single key-in-knob lock that is not on a master key system?
The Peaks 1CB is built around a patented key control system whose keys come only through authorized BEST distributors, which is what a facility wants when keying is controlled centrally. For one-off knob or lever replacement outside a controlled system, the Kaba Ilco 1539 Series is a universal key-in-knob and lever cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series 6-pin G keyway supplied keyed different with two cut keys. Those are fixed cylinders, so rekeying means pulling and repinning rather than swapping a core.
15) What cylinder do I use on a deadbolt instead of a Peaks 1CB core?
The Peaks 1CB 150 Series operates deadbolts when the deadbolt is BEST interchangeable core prepped, and it is ordered combinated or uncombinated in 606 Satin Brass or 626 Satin Chrome. For residential-style deadbolts and handlesets that take a rim type cylinder rather than a core, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts and the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. The Kaba Ilco 1549 Series is a key-in-deadbolt cylinder with a deadbolt function. Which one applies depends on whether the deadbolt is prepped for a core cavity or for a fixed cylinder with a tailpiece.
16) The lock brand on my doors is Sargent, not BEST. Is there a cylinder made for that instead?
The Peaks 1CB core is engineered for BEST interchangeable core hardware and stays compatible with BEST CORMAX or BEST Preferred components for later upgrades, so it belongs on doors already carrying BEST cores. Where the knob or lever is Sargent, the Kaba Ilco 1579 is a knob and lever cylinder made for Sargent. For an Arrow JL interconnected lock or an Emtek handleset and deadbolt outside cylinder, the Medeco 1065140 is a 5-pin retrofit cylinder built for those, and the Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece.
17) Is the BEST Peaks 1CB core rated for commercial traffic, or is it a residential part?
Commercial. The Peaks 1CB is a commercial-duty core, used in office buildings, schools, hospitals, government and municipal buildings, industrial and warehouse facilities, retail, and multi-tenant residential. It is a replacement part, meaning it goes into lock hardware you already own rather than being a complete lock.
