Schlage Commercial 20-057 6-Pin FSIC Rim Cylinder

The Schlage 20-057 is a 6-pin Full Size Interchangeable Core (FSIC) rim cylinder built on Schlage's modular cylinder platform. One core body converts to mortise, rim, or key-in-lever/knob applications by swapping the tailpiece, cam, or rear housing — reducing the inventory a locksmith or facilities team needs to carry without sacrificing compatibility across a large keying system.

Schlage 20-057 C 626 – Frequently Asked Questions

1) Will the Schlage 20-057 work as the keyed cylinder in a rim exit device?
That is what it is built for. The 20-057 is a 6-pin full size interchangeable core rim cylinder, so it goes into hardware prepped to take an FSIC rim cylinder, most commonly a rim exit device. It is non-handed, so the same part number serves a left hand or right hand opening with no separate order, and the convertible tailpiece cam lets the same core body be set up for rim, mortise, or key-in-lever and key-in-knob use by changing the tailpiece, cam, or rear housing.
2) Is the Schlage 20-057 a full size interchangeable core or a small format (SFIC) core?
Full size. The 20-057 is an FSIC 6-pin cylinder, so the hardware has to be prepped for a full size core; it will not drop into a small format figure-eight core prep. If a facility is already standardized on small format cores, the BEST 1C Series standard 5-pin core or the 1CB 150 Series interchangeable core is the family that fits that prep, and the BEST 1CDF is the drill resistant patented 7-pin version of it. Getting this wrong is the most common way an interchangeable core order comes back.
3) Does the Schlage 20-057 come keyed to my building's existing master key system?
No. The standard keyway versions ship 1 bitted with 2 keys, meaning the core carries a placeholder bitting and has to be combinated to your system by a locksmith before it goes in the door. It does pin up in Schlage Classic, Everest 29 and Primus XP systems, so an existing large keying system can absorb it rather than running a second system alongside. Order the keyway your system already uses: C, C123, C124, C125, C134, C135, C145, C234, CE, E, EF, F, FG, G, P, S123, S124, S125, S134, S135, S145 and S235 are the 22 standard choices.
4) The building is keyed to Corbin Russwin, not Schlage. What rim cylinder do I order for the rim exit device instead of the Schlage 20-057?
The Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, sized to take a Schlage full size interchangeable core. For an opening keyed to Corbin Russwin, the Corbin Russwin 3070 is a 6-pin rim cylinder housing from the Corbin Russwin 3000 series, supplied with a 1-7/8 inch tailpiece. Both are 6-pin rim cylinders. The 20-057 uses a convertible tailpiece cam that adapts the same body to rim, mortise, or key-in-lever work, while the 3070 is furnished with the 1-7/8 inch tailpiece length called out in its part number.
5) Our facility is a BEST interchangeable core house. What core do we use in place of the Schlage 20-057?
The Schlage 20-057 is a 6-pin FSIC cylinder keyed on Schlage keyways, including C, C123 through C234, CE, E, EF, F, FG, G, P, and S123 through S235, plus the ICA, ICB, ICC, and ICX construction keyways. A BEST-keyed facility works from BEST cores instead: the BEST Peaks 1CB is a 150 series interchangeable core cylinder, and the BEST 1C is a standard 5-pin cylinder core. The split is the keying platform and the pin count, since the 20-057 is 6-pin and the BEST 1C core is 5-pin.
6) The door has a Schlage L9000 mortise lock. Is the 20-057 the right cylinder, or is there a mortise part made for that lock?
The Schlage 20-057 is set up as a rim cylinder and converts to mortise or key-in-lever service by swapping the tailpiece, cam, or rear housing. For an L9000 mortise lock specifically, the Corbin Russwin 1080 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, built for Schlage L9000 mortise locks with an A01 Schlage L cam, so it arrives in the mortise length and cam the lock case expects rather than being converted to it.
7) Can one Schlage 20-057 core cover mortise and key-in-lever doors too, or do I stock a separate cylinder for each?
One core body covers all three. Schlage's modular cylinder platform lets the same core serve rim, mortise, and key-in-lever or key-in-knob applications by swapping the tailpiece, cam, or rear housing, so what changes at the door is the hardware around the core, not the core or its keying. For a locksmith van or a facilities crib keying a whole property, that means stocking fewer keyed parts and adapting on site instead of ordering an application-specific cylinder per opening.
8) What comes with the Schlage 20-057, and what else do I need to order to finish the job?
Standard keyway versions include 2 keys; the four construction keyways (ICA, ICB, ICC, ICX) ship with none. The cylinder is brass. What is not in the box is the keying, since standard cylinders arrive 1 bitted and need to be combinated to your system. If the core is going into a mortise lock or a key-in-lever lockset rather than rim hardware, the tailpiece, cam or rear housing for that application is a separate line on the order.
9) What are the ICA, ICB, ICC and ICX construction keyways on the Schlage 20-057, and why do they come with no keys?
Those four are construction keyway options, and they are ordered for a jobsite rather than for turnover. They ship with 0 keys because the construction keys are issued and controlled separately by the GC or the keying schedule, where the standard keyways come with 2 keys apiece. The point of interchangeable core on a construction job is that the temporary cores get pulled at handover and the permanent cores drop in without touching the door prep or the exit device.
10) Will a Schlage 20-057 cylinder work on a thicker than standard door?
Thicker doors are handled by the rear housing, not by a different cylinder. Schlage's modular platform offers six rear housing lengths to accommodate thicker doors, so the depth is matched by pairing the correct housing with the core. The 20-057 itself is the 6-pin FSIC rim cylinder with the convertible tailpiece cam; the housing choice is what adapts it to the door you have.
11) I don't need interchangeable cores. Is there a plain rim cylinder instead of the FSIC 20-057?
The Corbin Russwin 3070 is a conventional 6-pin rim cylinder housing with a 1-7/8 inch tailpiece, with no interchangeable core in the equation. Take the FSIC route with the Schlage 20-057 when cores need to be pulled and swapped by hand for tenant turnover, lost keys, or rekeying a portfolio in an afternoon. Take a fixed cylinder like the 3070 when it is one or two doors and a locksmith is going to rekey them in place anyway.
12) I need a mortise cylinder for a mortise lock, not a rim cylinder. What do I order?
The 20-057 is configured as a rim cylinder, though on the modular platform the same core converts to a mortise application by changing the cam and rear housing, so a core already keyed to your system is not wasted. For a purpose built mortise cylinder instead: the Corbin Russwin 1000 Grade 1 Series is 1-1/2 inch with an A02 straight cam, the 1070 Grade 1 Series is a 1-1/4 inch 6-pin housing with an A01 cloverleaf cam, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder cut to the Schlage C keyway. For a Schlage L9000 mortise lock, the Corbin Russwin 1080 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, with the A01 Schlage L cam.
13) Can the Schlage 20-057 replace the cylinder in a key-in-lever or key-in-knob lockset?
The modular platform converts to key-in-lever and key-in-knob use by swapping the tailpiece, cam or rear housing, so the 20-057 core can be moved into that application on hardware prepped for a full size core. Where the lockset is not interchangeable core prepped, a dedicated cylinder is the cleaner order: the Falcon A23161-05 G is a key-in-lever cylinder for the RU/T series, 6-pin G keyway, keyed different with 2 cut keys, and the Kaba Ilco 1539 Series is a universal key-in-knob and lever cylinder.
14) The opening is a narrow stile aluminum storefront with an Adams Rite MS1847 deadlock. Does the Schlage 20-057 fit it?
The Schlage 20-057 is a 6-pin FSIC rim cylinder on a convertible tailpiece cam, aimed at rim, mortise, and key-in-lever hardware. An MS1847 deadlock takes a part made for that lock: the Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock and deadlatch systems, and the Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847 deadlock. The 4024 mounts on a trim plate, the 4025 fastens with through-screws. For a wood door running an Adams Rite 5017 deadlock or deadlatch, the Adams Rite 4026 is the five pin tumbler cylinder pull built for that lock.
15) Is there an interchangeable core with drill resistance and a patented key rather than the Schlage 20-057?
The Schlage 20-057 is a 6-pin brass FSIC cylinder that interchanges across Everest 29, Primus XP, and Classic key systems. Where a drill resistant, patented core is wanted instead, the BEST 1CDF is a drill resistant preferred patented interchangeable core, 7-pin, brass, in the 150 series. The two differ in key system and pin count: the 20-057 is 6-pin on Schlage systems, the 1CDF is 7-pin on BEST.
16) I need a mortise cylinder and do not want to convert one. What are the mortise options next to the Schlage 20-057?
The Schlage 20-057 reaches mortise applications by changing the tailpiece, cam, or rear housing on its convertible tailpiece cam body. Two Corbin Russwin parts arrive as mortise cylinders out of the box: the Corbin Russwin 1070 is a 1-1/4 inch 6-pin mortise housing in the Grade 1 series with an A01 cloverleaf cam, and the Corbin Russwin 1000 is a Grade 1 series mortise cylinder in 1-1/2 inch length with an A02 straight cam. Choose between them on the cylinder length the lock case calls for and on cam style, cloverleaf versus straight.
17) What cylinder works on a very thin narrow stile door where the Schlage 20-057 has more body than the stile allows?
The Schlage 20-057 is a 6-pin FSIC cylinder that accommodates thicker doors through six rear housing lengths. Going the other direction, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security rated down to a 1/2 inch minimum door thickness, which is the range narrow stile aluminum work lives in. The 4036 is a five-pin mortise cylinder; the 20-057 is a 6-pin interchangeable core cylinder.
18) We are on the Schlage C keyway but do not run interchangeable cores. Is there a conventional cylinder that keys the same?
The Schlage 20-057 is offered in the C keyway among its options, and it is a 6-pin FSIC cylinder, so the core pulls with a control key. A crew that keys to Schlage C without wanting a removable core can use the Detex MC65, a 1-1/8 inch 6-pin commercial grade mortise cylinder cut to the Schlage C keyway. Both are 6-pin on the C keyway; the MC65 is a fixed mortise cylinder, the 20-057 is an interchangeable core in a rim configuration with a convertible tailpiece cam.
19) The job is a key-in-lever cylinder swap. Is there a part made for that rather than converting the Schlage 20-057?
The Schlage 20-057 reaches key-in-lever and key-in-knob applications by changing the rear housing, and it ships with 2 cut keys. A cylinder purpose-built for lever trim is the Falcon A23161-05 G, a key-in-lever cylinder for the RU/T series in a 6-pin G keyway, keyed different, supplied with 2 cut keys, in the Falcon Q330 series. Both are 6-pin and both come with two keys; the Falcon part is fixed to key-in-lever duty, while the 20-057 is an interchangeable core body that also serves rim and mortise openings.
20) I only need a blank cylinder on the inactive side with no key function. Do I still order the Schlage 20-057?
No. The Schlage 20-057 is a keyed 6-pin FSIC rim cylinder supplied with 2 keys, so it is more part than a blind side needs. Where the opening only wants the look of a rim cylinder with nothing to operate, the BEST 12E is a dummy rim cylinder with a 1-5/32 inch diameter in the 12E series. It fills the same rim prep, but it is a dummy and does not key or turn anything.
21) Search results show other cylinders called rim cylinders for deadbolts and handlesets. Are those the same thing as the Schlage 20-057?
They are not the same application. The Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam for commercial rim, mortise, and key-in-lever hardware. 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. Those carry the rim label because of the cylinder body style, but they are lazy motion cylinders sized to deadbolt and handleset backplates, not interchangeable cores for commercial rim devices.
22) What finishes does the Schlage 20-057 rim cylinder come in, and can I match it to the trim already on my doors?
Six finishes are offered: 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 622 matte black, 625 bright chrome, and 626 satin chrome. Those are BHMA finish numbers, so matching a visible rim cylinder to the exit device or lock trim already hung is a matter of ordering the same number that is on the existing hardware. The front housing is produced in every one of those finishes, which is what makes the match possible on the exposed side of the door.
23) Is a BEST 12E dummy rim cylinder an equivalent to the Schlage 20-057?
The 12E dummy is not a keyed cylinder. It is a dummy rim cylinder with a 1-5/32 inch diameter, so it fills the hole and reads as a cylinder from the outside without operating anything. The Schlage 20-057 is a keyed 6-pin FSIC rim cylinder that comes with 2 keys on the standard keyways. If a rim cylinder part number is being quoted for a secured opening, confirm it is a keyed unit and not a dummy before it ships.
24) The unit has an Emtek handleset or an Arrow interconnected lock. What outside cylinder goes there instead of the Schlage 20-057?
The Schlage 20-057 is a commercial 6-pin FSIC cylinder for rim, mortise, and key-in-lever hardware, so residential handleset trim is a different part. The Emtek CY4 is the Emtek cylinder sold as a single piece. On the Medeco side, the 1065244 is a 5-pin rim lazy motion rim type cylinder supplied with an Emtek tailpiece, and the 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and for Emtek handleset and deadbolt outside cylinder positions. Those three are 5-pin residential-format cylinders; the 20-057 is a 6-pin interchangeable core on commercial keyways.
25) What replaces a worn key-in-knob or key-in-deadbolt cylinder if the building is not on a Schlage interchangeable core system?
The Schlage 20-057 is a 6-pin FSIC cylinder that converts to key-in-lever and key-in-knob work by changing the rear housing, and it makes sense where the site keys to Schlage cores. Where it does not, the Kaba Ilco line covers straight replacements: the 1539 is a universal key-in-knob and lever cylinder, the 1599 is a key-in-knob replacement cylinder, the 1579 is a knob and lever cylinder for Sargent, and the 1549 is a key-in-deadbolt cylinder. Pick by the lock the cylinder is coming out of, since each of those is built for a specific trim rather than for core interchange.

    Slid right into the hole we made for our pedestrian gate! I had to look at the dimensions on the drawing and the dimensions were accurate!
