BEST BES-1CP7WA1605 – Frequently Asked Questions

1) Will a BEST 1CP premium core drop into my existing BEST small format interchangeable core hardware?
The 1CP premium core is a BEST interchangeable core, so it goes into BEST cylinder housings and BEST-prepped locksets that already take a removable core, pulled and replaced with a control key. It is the premium version of the 1C core family, which also includes the standard and drill resistant cores. What it will not do is fit a competitor's housing: a Schlage FSIC opening takes a full size core like the Schlage 20-057, and a mortise cylinder opening takes a threaded cylinder such as the Corbin Russwin 1000, not a core on its own. Match the core to BEST-prepped hardware, or order the housing along with it.
2) Do I order a 5-pin, 6-pin or 7-pin BEST core, and can I mix them in one master key system?
Three pin counts are offered on the 1CP premium core: 5-pin, 6-pin and 7-pin. Pick the one that matches the system already in the building, because pin count is set by the key system, not by the door. Six and seven pin systems give more room for master keying levels, which is what a campus or multi-building facility standardizing under one control key usually wants. A key cut for a 6-pin system will not operate a 7-pin core, so if you are adding doors to an existing BEST system, order the same pin count and the same keyway as the cores already in service.
3) Which BEST keyways can I get the 1CP premium core in?
Nine keyways are available on the 1CP premium core: WA, WB, WC, WD, WE, WG, WH, WK and WY. The keyway is the single most important thing to get right on the order, because a core in the wrong keyway will not accept your existing keys no matter what else matches. Pull an existing core, read the keyway stamp off it or off your key bow, and order to match. The keyway is paracentric, meaning the keyline crosses the center of the core, which is what gives the premium core its pick resistance.
4) What is the difference between ordering a BEST 1CP core combinated versus uncombinated?
Combinated means the core arrives pinned to a key combination you specify; uncombinated means it ships unpinned for your locksmith or in-house shop to combinate to the existing system. Both are offered on the 1CP premium core. If you order combinated, supply the keymark and the marking number from your key system records so the core is cut into the right master key hierarchy. Facilities with their own key shop and a pinning kit generally take uncombinated cores; property managers and contractors without a shop should order combinated.
5) I need to rekey a whole building. Can I just swap BEST cores instead of replacing the locks?
That is exactly what an interchangeable core system is for. With BEST-prepped hardware already on the doors, a rekey means pulling each core with the control key and dropping in a new 1CP premium core, no lock disassembly and no door off its hinges. A two-person crew can turn over a floor in an afternoon. Order the replacement cores in the same keyway and pin count as the system, combinated to the new hierarchy, and you have changed the building's keying without touching a single lock body. This is the standard approach for turnover in multi-tenant residential and for a lost-master-key event on a campus.
6) Is the BEST 1CP core the same thing as a Schlage full size interchangeable core?
No, and they are not interchangeable. The 1CP is a BEST core and fits BEST small format interchangeable core prep. A Schlage FSIC opening needs a full size core such as the Schlage 20-057, or the 20-057-C in C keyway. The two formats differ in size and in the control key that removes them, so a BEST core will not seat in a Schlage FSIC housing. Check what comes out of the door before you order: if the removed core has the figure-eight profile, you are in BEST territory.
7) What should be used for an exit device rim application instead of a BEST 1CP core?
Rim applications need a rim cylinder. The Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with two keys, and the 20-022 is the same rim cylinder with a horizontal tailpiece cam and two keys; the tailpiece orientation is set by the exit device chassis. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. The BEST 1CP is the removable core that goes into a compatible BEST cylinder assembly, so on a rim opening it is the core inside the housing, not the housing itself.
8) What is the closest equivalent to a BEST 1CP premium core if the door hardware is Schlage full size interchangeable core?
Use a Schlage FSIC core rather than a BEST 1CP. The BEST 1CP is a premium core built around a paracentric keyway, with the keyline crossing the center of the core, and it seats in compatible BEST cylinder assemblies. The Schlage 20-057-C is a full size interchangeable core in the Schlage C keyway, supplied in 643E aged bronze, and the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam that the core drops into. If the existing key system is Schlage C, the 20-057-C keeps the facility on one key; the BEST 1CP would require rekeying the opening to a BEST keyway such as WA, WB, or WC.
9) The opening needs a complete mortise cylinder, not just a core. What should be ordered instead?
A core alone will not fill a mortise prep. The BEST 1CP is the removable core only, ordered by core size in 5-pin, 6-pin, or 7-pin and by keyway, and it goes into a compatible BEST cylinder assembly. For a complete mortise cylinder, the Corbin Russwin 1000 Grade 1 series mortise cylinder is a 1-1/2 inch length with an A02 straight cam, and the Corbin Russwin 1070 Grade 1 series is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. Adams Rite offers the 4036 mortise cylinder with five-pin security, rated Grade 1, for doors 1/2 inch minimum thickness. Confirm cam style against the lock case before ordering.
10) How is a BEST premium core different from a standard BEST core, and is it worth it?
Two things separate the premium core from the standard one. The keyway is paracentric, with the keyline crossing the center of the core, which resists picking better than a straighter keyway. And the premium keys themselves are physically larger and heavier than standard BEST keys, so they hold up under the kind of daily use a school corridor or a hospital wing puts on a key. The 1C family also includes a drill resistant core if physical attack rather than picking is the concern. For a back-of-house storage room, a standard core is enough; for exterior doors, cash handling areas and anywhere key control actually matters, the premium core is the one to spec.
11) What finishes does the BEST 1CP core come in, and does the core finish need to match my lever trim?
Eight finishes are offered: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome, 626 satin chrome and 690 statuary dark bronze. Only the core face shows once it is installed, so the practical job is matching that face to the lock trim around it. Satin chrome 626 is the usual commercial default and the one most institutional standards specify; 613 and 690 are the ones to pick against dark bronze door hardware. If you are replacing cores across a building, order one finish for the whole run so the openings read consistently.
12) What do I need to supply when ordering combinated BEST 1CP cores for an existing key system?
Two pieces of information off your key system records: the keymark and the marking number. Those tell the factory where the core sits in your master key hierarchy so the new core operates under the same masters and the same control key as the rest of the building. Alongside that, specify keyway, pin count and finish. Without the keymark and marking number, the core cannot be cut into your existing system and you will get a standalone keying instead.
13) I have a mortise lock that needs a new cylinder. Is a BEST core the right part?
Not on its own. A core is the removable plug; a mortise lock needs a threaded mortise cylinder body with the correct cam, unless the lock is already prepped for a BEST interchangeable core. If it is a conventional mortise prep, look at a threaded cylinder sized to the door and trim: the Corbin Russwin 1000 Grade 1 in 1-1/2 inch length with an A02 straight cam, the 1070 in 1-1/4 inch with an A01 cloverleaf cam, or the Detex MC65 in 1-1/8 inch with Schlage C keyway. The cam style has to match the lock body, so identify the lock before choosing.
14) Can a BEST 1CP core be used to rekey a residential handleset or deadbolt?
No, that is a different part. Handleset and deadbolt retrofits take a rim type cylinder built for the specific 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 the Emtek handleset and deadbolt outside cylinder. Emtek also lists the CY4 cylinder sold each. The BEST 1CP is a commercial premium core.
15) What is the difference between a BEST 1CP core and a Corbin Russwin 1080 LFIC mortise cylinder?
They sit at different points in the assembly. The BEST 1CP is a premium interchangeable core with a paracentric keyway, sold uncombinated or combinated and in 5-pin, 6-pin, or 7-pin sizes. The Corbin Russwin 1080 is a Grade 1 series 1-1/2 inch LFIC mortise cylinder, 6-pin, for Schlage L9000 mortise locks, with an A01 Schlage L cam. The 1080 is the housing that carries a large format interchangeable core and threads into the lock case; the 1CP is the core itself. Ordering a core when the opening has no housing, or a housing when only the core needs changing, is the common miss on this pairing.
16) For a key-in-knob or key-in-lever lockset that is not interchangeable core, what replaces the cylinder?
Those locksets take a knob or lever cylinder rather than a removable core. 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 for Sargent locksets; the Kaba Ilco 1549 is the key-in-deadbolt version. The Falcon A23161-05 G is a key-in-lever cylinder for the RU/T series with a 6-pin G keyway, keyed different and supplied with two cut keys. The BEST 1CP is a premium interchangeable core and is used only where the lockset is built to accept a removable core.
17) What looks like a substitute for a BEST 1CP core but will not work in the same opening?
A cylinder pull is the frequent mix-up on aluminum storefront. The Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847 deadlock or deadlatch, and the 4026 is a five pin tumbler cylinder pull for wood door applications with the Adams Rite 5017 wood door deadlock or deadlatch. Those are pull and cylinder units tied to a specific Adams Rite lock. The BEST 1CP is a removable core for a compatible BEST cylinder assembly and does not mount to a door on its own.
18) Is the BEST 1CP premium core suitable for a hospital, school or government building?
Those are the applications it is built for. The 1CP is a commercial core, and the reason it turns up in healthcare, education and municipal facilities is key control: one control key pulls every core in the building, master key levels can be structured department by department, and a compromised key means swapping cores rather than replacing locks. The premium keys are heavier stock than standard BEST keys, which matters where the same key gets used dozens of times a day. Available in 5, 6 and 7 pin so it can be layered into a large hierarchy.
