Schlage 20-001 S123 158 626 – Frequently Asked Questions

1) How do I know a Schlage 20-001 mortise cylinder will actually operate my lock?
The cam decides it. The 20-001 ships with the straight cam, cam number L583-476, and that is the part that swings behind the lock case to retract the latch or throw the bolt. Pull the cylinder that is in the door now and look at the tail end: if it has a cloverleaf, offset or horizontal cam instead of a straight one, the lock wants that shape and this cylinder as supplied will not drive it. On a modular cylinder the cam is a changeable component, so the body and keying can stay while the cam is matched to the lock.
2) Can a Schlage 20-001 mortise cylinder be keyed into the master key system I already have?
Keyway is an ordering choice, so you match the section your building is already on. Sections offered include C, E, F, G, CE, EF and FG, along with numbered sections such as C123, C134, C145, C245, C345, S123 and S235. The modular platform supports interchangeability between Everest 29, Primus XP and Classic key systems, which is what lets a facility on one of those move cylinders around without re-cutting the whole system. Two cut keys come with the cylinder.
3) What is the compression ring and spring on a mortise cylinder for, and is it included?
Both are included with the 20-001. The ring and spring sit between the cylinder collar and the lock trim and take up whatever gap is left when the cylinder is threaded in. That matters because a mortise cylinder has to stop with the keyway upright: you back it off to square the key slot, and the spring keeps it loaded against the trim so it does not sit proud or rattle at that position. Skip them and you are choosing between a cylinder that is loose and one that is cranked past straight.
4) I need mortise cylinders that match the lever finish across my building. What finishes does the Schlage 20-001 come in?
Finishes run 605 bright brass, 606 satin brass, 609 antique brass, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 629 bright stainless steel, 630 satin stainless steel and 643E aged bronze. Match the lock trim rather than the door pull, because the cylinder face and collar land right against the escutcheon or rose, and 626 next to 630 reads as a mismatch down a corridor. The front housing is produced in all the lock finishes for exactly that reason.
5) Is the Schlage 20-001 cylinder certified to a commercial standard I can put on a submittal?
BHMA certified to ANSI A156.5 2001, the standard that covers cylinders and input devices for locks, and it is built as commercial hardware rather than residential. That is the line most facilities and government submittals want next to a cylinder, and it is the same certification basis you would cite for standardizing cylinders across a campus or a portfolio.
6) Can one Schlage modular cylinder cover mortise, rim and key-in-lever, or do I have to stock all three?
One body covers all three. The 20-001 is configured as a mortise cylinder, but the modular design converts to rim and to key-in-lever or key-in-knob by changing the tailpiece, cam or rear housing rather than buying a different cylinder. For a locksmith van or a service counter that changes what you carry: cylinder bodies in the keyways your accounts actually use, plus housings, cams and tailpieces on the shelf, instead of three separate cylinder inventories in every keyway and finish.
7) The doors on my job are thicker than standard. Will a Schlage modular mortise cylinder still reach?
Rear housing length is what you change for a thick door, and six rear housing lengths are made for that. The cylinder body, keying and finish stay the same; the housing behind it makes up the extra depth so the cam still lands where the lock case wants it. Same answer when a heavy escutcheon or an added armor front pushes the cylinder further out than a standard prep.
8) How much key control do I get with a Schlage modular cylinder, and can I upgrade it later?
Security here is a key system decision, not a different cylinder. The 20-001 is offered at both basic and enhanced security levels depending on how it is ordered, and the platform supports Everest 29 and Primus XP alongside Classic. That means a property can start on a standard section and move to a higher control system later without changing the cylinder type in every mortise lock, which is the usual sticking point when a building decides key duplication has gotten out of hand.
9) I want interchangeable core on my Schlage mortise locks instead of a conventional cylinder. What should I order?
A conventional mortise cylinder like the 20-001 is pinned in the cylinder itself, so rekeying means pulling it and taking it apart. If you want keying changed by swapping a core with a control key, the Corbin Russwin 1080 Series 1-1/2 inch LFIC mortise cylinder is a 6-pin large format interchangeable core cylinder listed for Schlage L9000 mortise locks with the A01 Schlage L cam. Same opening, different way of controlling the keying. On a small format IC system instead, a core such as the BEST 1C 5-pin standard core is the part to look at.
10) What else can I put in a mortise lock if this Schlage cylinder is not the right length or keyway for the job?
Two useful directions. The Detex MC65 is a 6-pin mortise cylinder at 1-1/8 inch on the Schlage C keyway, so it fits where a shorter body is needed but the building is already keyed on C. If the site is keyed on Corbin Russwin instead, the 1000 Series Grade 1 mortise cylinder at 1-1/2 inch with the A02 straight cam is the equivalent part with the same straight cam action. Match the cam shape first, then length, then keyway; getting the order of those wrong is how the wrong cylinder ends up on site.
11) What cylinder goes in a narrow stile aluminum storefront door with an Adams Rite deadlock?
For a threaded mortise cylinder in that kind of door, the Adams Rite 4036 mortise cylinder is the Grade 1 part built for it and works from a 1/2 inch minimum door thickness, which is the range narrow stile aluminum sits in. Do not confuse it with the cylinder pulls: the 4024 and 4025 are pull assemblies with the cylinder built in for the MS1847 deadlock, and the 4026 is the wood door version for the 5017 deadlock. Those replace a pull and a cylinder together, so they are not a swap for a plain mortise cylinder hole.
12) The mortise lock on the door is Corbin Russwin rather than Schlage, but it still needs a straight cam cylinder. What is the equivalent?
Order the Corbin Russwin 1000 Grade 1 series mortise cylinder, 1-1/2 inch length, which is supplied with the A02 straight cam. It carries the same straight cam idea into a Corbin Russwin lock body. The Schlage 20-001 is a mortise cylinder that ships with the L583-476 straight cam, which is the Schlage cam part. Straight cam is what the two share; the cam part number and the lock line each one is built for are what separate them, so buy by the brand of the mortise lock already in the door.
13) My mortise lock takes a cloverleaf cam, not a straight one. What do I order instead?
The cam is the part that turns inside the lock case, so the shape has to match the lock and the two profiles are not interchangeable. For a cloverleaf, the Corbin Russwin 1070 Grade 1 series is a 1-1/4 inch 6-pin mortise housing supplied with the A01 cloverleaft cam. The Schlage 20-001 comes with the L583-476 straight cam instead. If you are unsure which is in the door now, pull the existing cylinder and look at the tail end before ordering.
14) We want maintenance to rekey doors in house without pulling cylinders out of the locks. What should we be buying instead?
That points at an interchangeable core cylinder, where the core comes out with a control key and the housing stays in the lock. The BEST Peaks 1CB is a 150 series interchangeable core cylinder, and the BEST 1C series standard 5-pin core is the core itself from the standard and premium cores line. For a drill resistant, patented core the BEST 1CDF is a 7-pin brass 150 series interchangeable core. The Schlage 20-001 is a conventional keyed mortise cylinder supplied with two keys, so rekeying it means pinning the cylinder rather than swapping a core.
15) We are standardizing our building on large format interchangeable core but the mortise locks are Schlage L9000. Is there a cylinder that does both?
Yes. The Corbin Russwin 1080 Grade 1 series is a 1-1/2 inch large format interchangeable core mortise cylinder, 6-pin, built for Schlage L9000 mortise locks and supplied with the A01 Schlage L cam. That lets an interchangeable core program run in the Schlage mortise lock bodies you already have. The Schlage 20-001 is the conventional route for those same locks, using the L583-476 straight cam and two keys per cylinder.
16) The exit device on our stair door takes a cylinder that turns a flat bar, not a cam. Will a 20-001 work there?
A flat bar means a rim cylinder, and a mortise cylinder assembly will not drive it. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece, which is the flat bar you are describing. The Schlage 20-001 is set up as a mortise cylinder driving the L583-476 cam. Worth knowing for a stocking decision: the Schlage modular cylinder is adaptable to mortise, rim and key-in-lever or key-in-knob applications by changing the tailpiece, cam or rear housing, so the same core family reaches rim work even though the mortise assembly as built does not.
17) The mortise pocket is shallow and I need something shorter that is already cut for Schlage C. What are my options?
The Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder cut to the Schlage C keyway, so it drops into a Schlage C key system on a shorter body. The Schlage 20-001 is also offered in the C keyway, in finishes including 626 satin chrome. Measure the depth of the existing cylinder and the thickness of the door section before you pick, because the length is what decides whether the cam lands where the lock case wants it.
18) It is a glass front entrance with an Adams Rite deadlatch in the stile. Is the 20-001 the right cylinder for that?
No, that opening takes Adams Rite parts. For the MS1847 deadlock and deadlatch, the 4024 is a cylinder pull with trim plate mounting and the 4025 is a five pin tumbler cylinder pull with through-screws; on a wood door with the 5017 deadlock the 4026 five pin tumbler cylinder pull is the one designed for it. If you need a keyed mortise cylinder for a thin section, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder rated down to a 1/2 inch minimum door thickness. The Schlage 20-001 is a commercial mortise cylinder for Schlage mortise lock bodies, driving the L583-476 straight cam.
19) Same key system, but this door has a lever lock instead of a mortise lock. What cylinder goes in it?
A key-in-lever cylinder, which is a different body from a mortise cylinder. The Falcon A23161-05 G is a RU/T series 6-pin key in lever cylinder in the G keyway, keyed different, supplied with two cut keys. The Kaba Ilco 1539 series is a universal key-in-knob and lever cylinder if you are covering mixed lock brands. The Schlage 20-001 is offered in the G keyway as well, so the key system can stay consistent across both door types while the cylinder body changes to suit the lock.
20) Can I use the same cylinder on the Kwikset deadbolts in our residential units so everything is on one key?
Those deadbolts take a different cylinder entirely. The Medeco 1012040 is a 6-pin lazy motion rim cylinder made for Kwikset single cylinder deadbolts, and the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. For an Arrow JL interconnected lock or an Emtek handleset and deadbolt outside cylinder, the Medeco 1065140 is the 5-pin retrofit. The Schlage 20-001 is a commercial mortise cylinder, so it belongs on the mortise locks in the common areas rather than on unit deadbolts.
21) I need a blank cylinder to fill the hole on a pull side that is never keyed. Is there a version of this for that?
For a non-keyed opening, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is the part built for that purpose. The Schlage 20-001 is a keyed mortise cylinder that ships with two keys and the L583-476 straight cam, so specifying it for a blank position means paying for key function you will not use and adding a keyway to your key records.
22) Our facility spec calls out a Grade 1 cylinder. Which mortise cylinders meet that on paper?
On the Corbin Russwin side, the 1000 series mortise cylinder in 1-1/2 inch with the A02 straight cam, the 1070 series 1-1/4 inch 6-pin mortise housing, and the 1080 series 1-1/2 inch large format interchangeable core mortise cylinder are all Grade 1 series products. The Adams Rite 4036 mortise cylinder is Grade 1 as well. The Schlage 20-001 is BHMA certified to ANSI A156.5 2001, which is the cylinder and input device standard your spec section is written against, so send the submittal with the certification line and the cam number L583-476 on it.
