Schlage 20-021 S123 626 – Frequently Asked Questions

1) Can I get the Schlage 20-021 keyed alike to the other locks in my building?
Yes. Keying is a required choice on the 20-021: keyed different (the standard), or keyed alike if you want several cylinders to run on one key. There's also a key code field, so if your building is already on a Schlage system you can supply the existing code and have these cut to match. A less-cylinder option is there too, for when you're supplying your own core or keying it yourself.
2) Will a Schlage 20-021 cylinder work with Primus XP or Everest 29 keys?
Yes. The Schlage modular cylinder supports interchangeability between Everest 29, Primus XP, and Classic key systems, and it accepts any Schlage keyway. So a facility running Primus XP for restricted key control can put a 20-021 on the exit devices and keep everything on one system.
3) I have a Corbin Russwin exit device, not Schlage. Do I still use the 20-021 rim cylinder?
Only if you're standardizing that opening on Schlage keys. The 20-021 is a Schlage-keyway cylinder, so it puts that device on your Schlage system. If the building is keyed to Corbin Russwin, use the Corbin Russwin 3070 6-pin rim cylinder housing with the 1-7/8 inch tailpiece instead, so the new cylinder matches the keys your staff already carry. The decision is which key system the door belongs to, not which brand the device is.
4) Can I use the Schlage 20-021 in a small format interchangeable core opening?
No. The 20-021 is a conventional rim cylinder, a fixed pinned cylinder that is re-keyed at the bench. If your facility runs interchangeable core so maintenance can swap cores with a control key, you want an IC product instead: the BEST 1CB 150 Series interchangeable core, the BEST 1C Series standard 5-pin core, or the BEST 1CDF drill resistant 7-pin brass 150 Series core. Mixing conventional and IC on the same building defeats the point of the control key.
5) I need a cylinder for a Schlage mortise lock, not an exit device. What should I order instead of the 20-021?
The 20-021 is set up as a rim cylinder and its listed compatibility is exit devices, so it is the wrong end of the job for a mortise lock. For a mortise body that takes a Schlage L-series cam, 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. If the mortise lock is Corbin Russwin rather than Schlage, the 1000 series mortise cylinder in 1-1/2 inch length with an A02 straight cam, or the 1070 6-pin mortise housing in 1-1/4 inch with an A01 cloverleaf cam, cover the common cam styles.
6) What is the closest equivalent to a Schlage 20-021 rim cylinder from another manufacturer?
The Corbin Russwin 3070 is the nearest peer: a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece, from the Corbin Russwin 3000 series. Like the Schlage 20-021, it is a 6-pin rim cylinder built to drive rim-mounted hardware through a tailpiece rather than a mortise cam. The difference that decides the order is the key system: the 20-021 accepts any Schlage keyway and supports interchangeability between Everest 29, Primus XP, and Classic key systems, so it drops into a Schlage-keyed building; the 3070 sits on the Corbin Russwin side. If the site is already keyed Schlage, the 20-021 keeps the master key system intact.
7) Our facility is on a BEST interchangeable core system. Can we use the Schlage 20-021, or do we need something else?
A building standardized on interchangeable core is a different keying architecture. The 20-021 is a conventional rim cylinder that is pinned in the cylinder body and accepts Schlage keyways. On an IC system the core is what carries the keying and gets swapped: the BEST 1CB is a 150 series interchangeable core cylinder, the 1CDF is a drill resistant patented interchangeable core in 7-pin brass, and the 1C 5-pin core covers the standard core position. Keep the 20-021 for openings you are keying to a Schlage system, and use the IC cores where the facility's rekey program depends on pulling a core with a control key.
8) What do I use on an aluminum storefront door with an Adams Rite deadlock instead of a Schlage 20-021?
An MS1847 deadlock on a narrow stile storefront takes a cylinder pull, not a rim cylinder. The Adams Rite 4024 cylinder pull mounts with a trim plate for MS1847 deadlock systems, and the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847 deadlock. For a wood door version, the Adams Rite 4026 five pin tumbler cylinder pull is made for the 5017 wood door deadlock. The Schlage 20-021 stays with exit device applications, which is the compatibility it is built around.
9) A Medeco rim cylinder and the Schlage 20-021 are both rim cylinders. Are they interchangeable?
Not by default, because rim cylinders differ by the motion they drive. The Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065244 is a 5-pin lazy motion rim type cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Those are lazy motion cylinders matched to residential-style deadbolts and handlesets. The Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and is listed for exit device compatibility. Match the tailpiece and the driven hardware before treating any two rim cylinders as swaps.
10) We key the whole property to Schlage C. Is there another mortise cylinder that stays on that keyway?
Yes. The Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder cut to the Schlage C keyway, so it stays inside a Schlage C master key system while serving a mortise prep. The Schlage 20-021 covers the rim side of the same system and is offered in the C keyway along with C123, C124, C125, C134, C135, C145, CE, E, EF, F, FG, G and S123. Between the two, a property manager can keep exit devices and mortise openings on one key.
11) Does the Schlage 20-021 fit Schlage locksets and deadbolts too, or only exit devices?
The modular cylinder design fits all Schlage locksets and deadbolts and accepts any Schlage keyway. As shipped, the 20-021 is configured as a rim cylinder with a vertical tailpiece cam for exit device use; to run it in a mortise lock or a key-in-lever you change the tailpiece, cam, or rear housing.
12) Do I need to worry about handing when ordering a rim cylinder for my exit device?
Not with the 20-021. It's non-handed, so one part number covers left and right hand doors. Handing on the exit device itself still matters, but the cylinder doesn't add another variable to the order.
13) Can I order Schlage 20-021 cylinders without keys or uncut?
Yes. Keying offers a less cylinder option alongside keyed different and keyed alike, which is how locksmiths order when they're pinning to their own system. Standard orders are keyed different and come with 2 keys; keyed alike puts multiple cylinders on one key. If you're matching an existing Schlage system, enter your key code with the order.
14) Which cylinder should I stock if I want to cover the most lock types with the fewest part numbers?
The Schlage 20-021 is built on the Schlage modular cylinder, where one cylinder converts to three different cylinder types by changing the tailpiece, cam or rear housing, covering mortise, rim and key-in-lever or key-in-knob applications, with six rear housing lengths for thicker doors and front housings in all finishes to match the locks. On the interchangeable core side, the BEST 1CB 150 series core and the 1CDF drill resistant patented 7-pin core do the equivalent job by making the core the swappable element. Which one reduces your shelf depends on whether the buildings you service are keyed Schlage or on an IC system.
15) Is the BEST 12E dummy rim cylinder a substitute for a Schlage 20-021?
No. The BEST 12E is a dummy rim cylinder with a 1-5/32 inch diameter, meaning it fills the rim prep and presents a face without operating anything. The Schlage 20-021 is a working 6-pin rim cylinder with a vertical tailpiece cam that turns the hardware and ships with two keys. Use the 12E only where the opening needs the appearance of a keyed cylinder on a leaf that is not keyed; anywhere a key has to retract or dog the device, the 20-021 is the part.
16) I need a Grade 1 mortise cylinder for a spec that calls out a grade. How does that compare to the Schlage 20-021?
The 20-021 is a rim cylinder for exit device applications, so a mortise line item on a drawing is a different part. Among mortise cylinders, the Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1 in the 4036 series with a 1/2 inch minimum door thickness, and the Corbin Russwin 1000, 1070 and 1080 are Grade 1 series mortise cylinders. Match the cylinder to the lock body the drawing specifies, then confirm the cam style: A02 straight on the 1000, A01 cloverleaf on the 1070, A01 Schlage L cam on the 1080.
17) The lock is a key-in-lever, not an exit device. Is the Schlage 20-021 still the right cylinder?
For a key-in-lever or key-in-knob position, order the cylinder built for that hardware. The Falcon A23161-05 G is a key-in-lever cylinder, RU/T series 6-pin in the G keyway, keyed different with two cut keys. Kaba Ilco covers the retrofit side: the 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. The Schlage 20-021 is configured as a rim cylinder with a vertical tailpiece cam, which is the exit device side of the building.
18) What cylinder pairs with an Emtek handleset or an Arrow interconnected lock?
Those take retrofit cylinders cut for that specific hardware. The Emtek CY4 is Emtek's own cylinder, and the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and for the Emtek handleset and deadbolt outside cylinder. The Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece. The Schlage 20-021 is a commercial 6-pin rim cylinder with a vertical tailpiece cam for exit device use, so it is a different application entirely.
19) Is a Kaba Ilco deadbolt cylinder a valid replacement for a Schlage 20-021?
Not for the same opening. The Kaba Ilco 1549 is a key-in-deadbolt cylinder and the 1539, 1579 and 1599 are also catalogued for deadbolt function, so they serve deadbolt and knob or lever positions. The Schlage 20-021 is a 6-pin rim cylinder whose listed compatibility is exit devices, in brass and stainless steel, and it is non-handed. If the door being worked on has a deadbolt, the Ilco parts are the family to look at; if it has a rim exit device, the 20-021 is.
20) What finishes does the Schlage 20-021 rim cylinder come in?
Seven: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 622 matte black, 625 bright chrome, and 626 satin chrome. On exit device work 626 satin chrome and 630-family stainless trim are the usual pairing, so 626 is what most commercial openings take. Pick the number off your existing trim rather than the color name, since satin chrome and satin brass read very differently side by side on a storefront.
21) What is the Schlage 20-021 rim cylinder made of?
Brass and stainless steel. It's a commercial-duty part, not a residential cylinder, which is why it turns up on exit devices in schools, hospitals, and multi-family corridors rather than on house doors.
