Schlage Commercial 20-001 1-1/8" 6-Pin Mortise Cylinder

The Schlage 20-001 is a 6-pin mortise cylinder supplied with a straight cam (L583-476), compression ring, and spring. It is certified to ANSI A156.5 2001 and is available in all standard Schlage keyways, including C, C123, C124, C125, C134, C135, C145, C234, C235, C245, C345, CE, E, EF, F, FG, G, S123, S124, S125, S134, S135, S145, S234, S235, and S345. Non-handed. Includes 2 keys.

Modular Cylinder System

The Schlage modular cylinder is a single core that converts to multiple cylinder types by swapping the tailpiece, cam, or rear housing. One cylinder covers mortise, rim, and key-in-lever or key-in-knob applications, reducing the number of parts required to fill a service call.

  • One cylinder converts to three cylinder types by changing the tailpiece, cam, or rear housing
  • Accommodates thicker doors with six available rear housing lengths
  • Front housing available in all finishes to match existing hardware
  • Supports interchangeability between Everest 29™, Primus® XP, and Classic key systems
  • Fewer parts required per order means lower inventory cost

Schlage 20-001 S123 118 626 – Frequently Asked Questions

1) Will the Schlage 20-001 cylinder work in my mortise lock, or do I need a different cam?
The 20-001 comes with a straight cam, cam number L583-476. The cam is the part that has to match your lock body: a case built to be driven by a straight cam will not run reliably off a cloverleaf, and the reverse holds too. Pull the existing cylinder and look at the cam shape before you order. If your case takes a cloverleaf, that is a different part. The Corbin Russwin 1080 Series LFIC mortise cylinder, for instance, carries the A01 cloverleaf cam for Schlage L9000 mortise locks.
2) Is a 1-1/8 inch mortise cylinder long enough for my door, or do I need a longer one?
1-1/8 inches is the standard mortise cylinder length, and it is what a normal 1-3/4 inch commercial door with a mortise case and flush trim takes. Length trouble comes from trim depth, not door thickness on its own: an escutcheon or thick decorative plate stacks depth in front of the case and pushes the cam back. Measure from the face of the trim to the cam pocket in the lock case, not across the door. The Schlage modular platform covers the deeper openings with six rear housing lengths, so you step the housing up instead of buying a whole different cylinder. Set right, the cylinder face sits flush with the trim, not recessed and not loose.
3) Can Schlage 20-001 mortise cylinders be keyed alike so one key runs a whole building?
Yes, keying is something you specify when you order. Keyed different gives every opening its own key, keyed alike puts a group of cylinders on one key, and there is a field for the key code when the new cylinders have to work an existing system. Two cut keys ship with each cylinder. The one thing that has to line up first is the keyway: cylinders can only be keyed alike inside the same keyway section, so order the entire group in one keyway and match it to what the building already carries.
4) Which Schlage keyway do I order so these mortise cylinders take the keys we already carry?
Twenty six keyway sections are offered on the 20-001: C, CE, E, EF, F, FG and G, plus the multi-section C123, C124, C125, C134, C135, C145, C234, C235, C245 and C345, and S123, S124, S125, S134, S135, S145, S234, S235 and S345. Match the section stamped on the bow of a key you already hold rather than guessing from the lock. The modular cylinder platform supports interchangeability between Everest 29, Primus XP and Classic key systems, so an existing system does not force you off the platform. Order the whole job in one section if the cylinders need to work together.
5) Which other brand makes a mortise cylinder that takes a Schlage C key?
The Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder cut to the Schlage C keyway, so it accepts the same key as a C keyway Schlage 20-001. The 20-001 offers C keyway as well, plus the Everest sections C123 through C345 and S123 through S345 and the E, EF, F, FG and G keyways. If the building is keyed on plain C, either cylinder keys into it; if the system runs on one of the restricted sections, that section is on the 20-001 keyway list.
6) My mortise lock needs a cloverleaf cam, not a straight cam. What do I order?
The Schlage 20-001 carries the L583-476 straight cam. For a cloverleaf tail, the Corbin Russwin 1070 is a Grade 1 series 1-1/4 inch 6-pin mortise housing with the A01 cloverleaf cam, and the Corbin Russwin 1080 is a Grade 1 series 1-1/2 inch 6-pin LFIC mortise cylinder with the A01 cam for Schlage L9000 mortise locks. The 20-001 is a modular cylinder, and the cam, tailpiece and rear housing are the parts that change to convert it, so cam style is a component decision on that platform rather than a separate cylinder line.
7) Our mortise locks are Schlage L9000 and the facility runs on interchangeable cores. What mortise cylinder fits?
The Corbin Russwin 1080 is a Grade 1 series 1-1/2 inch large format interchangeable core mortise cylinder, 6-pin, built for Schlage L9000 mortise locks with the A01 Schlage L cam. It seats a removable core, so a rekey at the door is a core swap. The Schlage 20-001 is a conventional keyed mortise cylinder supplied with a compression ring and spring rather than a removable core, and it is BHMA certified to ANSI A156.5 2001.
8) What mortise cylinder goes into an aluminum storefront door with an Adams Rite deadlock?
The Adams Rite 4036 is a Grade 1 five-pin mortise cylinder in the 4036 series with a 1/2 inch minimum door thickness, which is the range narrow stile aluminum work sits in, and Adams Rite's cylinder pulls in the same family serve the MS1847 and 5017 deadlock and deadlatch bodies. The Schlage 20-001 is a mortise cylinder BHMA certified to ANSI A156.5 2001 for a standard mortise lock body, non-handed, so it goes in either way the door swings.
9) Can a Schlage modular cylinder be converted to a rim or key-in-lever cylinder later?
That is the whole idea behind the modular design. One cylinder converts to three types, mortise, rim, and key-in-lever or key-in-knob, by changing the tailpiece, cam or rear housing. The 20-001 arrives configured as a mortise cylinder with a straight cam, so converting means swapping the cam for the correct tailpiece and rear housing. For a locksmith stocking a van, that is one cylinder covering three calls instead of three separate part numbers. If all you need today is a rim cylinder and nothing else, a purpose-built one such as the Corbin Russwin 3070 6-pin rim housing with a 1-7/8 inch tailpiece is the simpler buy.
10) What are the compression ring and spring on this Schlage mortise cylinder for, and do they come with it?
They come with the cylinder. The ring and spring sit behind the collar and take up the gap between the cylinder and the lock case, so you can thread the cylinder in to the exact depth where the cam meets the lock's actuator and still have it pull up tight instead of sitting loose or backing out with use. On doors where the trim adds depth, that adjustment is what gets the cylinder face flush with the trim. Nothing else to buy for a standard install. A longer rear housing only enters the picture when the depth runs past what this length reaches.
11) Does the Schlage 20-001 mortise cylinder meet ANSI standards for a commercial spec?
BHMA certified to ANSI A156.5 2001, which is the standard covering cylinders and input devices for locks, and it is built as a commercial part rather than a residential one. That is the line to quote when a facility spec or a submittal asks for a certified cylinder. The cam and keyway still have to match the opening, but on the certification question the 20-001 answers it.
12) Do I need a different mortise cylinder for left hand and right hand doors?
No. The 20-001 is non-handed, so the same cylinder goes into a left hand or a right hand opening. Handing lives in the lock case and the trim, not in the cylinder. For anyone standardizing a run of openings, that means one line item covers the building, provided the mortise cases all take a straight cam and you order everything in a common keyway.
13) What do I use when the mortise cylinder has to be longer than 1-1/8 inches?
Two routes. Staying on the Schlage modular platform, you keep the cylinder and step up the rear housing; six lengths are offered, and that is what the modular design is for. If the job is not tied to Schlage, the Corbin Russwin 1000 Series Grade 1 mortise cylinder is a 1-1/2 inch length with an A02 straight cam, and the 1070 Series is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. Measure trim face to cam pocket before you pick, because trim depth drives length more often than door thickness does.
14) We rekey on every tenant turnover. Is a conventional mortise cylinder the right call, or should we go interchangeable core?
The 20-001 is a conventional cylinder, so rekeying it means pulling the cylinder and repinning it, one locksmith visit per opening. Where turnover is constant, an interchangeable core changes the economics: the core comes out with a control key and a fresh one drops in without touching the lock case. BEST covers that side, with the 1C Series standard 5-pin core, the Peaks 1CB 150 Series interchangeable core cylinder, and the 1CDF drill resistant patented 7-pin core in the 150 Series. Going IC is a system decision though, since every opening needs core-ready housings. If your doors are already prepped for conventional Schlage mortise cylinders, the 20-001 keeps you inside that system without a changeover.
15) Can I put a key-in-knob or rim cylinder in a mortise lock instead of a mortise cylinder?
No, those three are not interchangeable in the same prep. A mortise cylinder threads into the lock case and turns a cam, a rim cylinder mounts through the door and drives a tailpiece, and a key-in-knob or lever cylinder drops into the knob or lever itself. The 20-001 is the mortise version, straight cam, cam number L583-476. Parts that look close but will not do this job: the BEST 12E Series dummy rim cylinder has no key function at all, the Kaba Ilco 1539 and 1599 Series are key-in-knob and lever cylinders, and the Corbin Russwin 3070 is a rim housing.
16) The door is thicker than standard and the cylinder does not reach. What are my options?
Corbin Russwin sells discrete lengths for this: the 1000 series mortise cylinder in 1-1/2 inch with the A02 straight cam, and the 1070 series mortise housing in 1-1/4 inch. The Schlage 20-001 takes the other approach, since the modular cylinder accommodates thicker doors through six available rear housing lengths, so the extra depth comes from the rear housing rather than from a different cylinder part number.
17) Can I put a BEST core into a mortise lock instead of buying a full cylinder?
A BEST core is the keyed plug assembly, not a complete cylinder. The 1C5 is a standard 5-pin cylinder core, the 1CB is a Peaks 1CB 150 series interchangeable core cylinder, and the 1CDF is a drill resistant patented interchangeable core, 7-pin, brass, 150 series. Each of those needs an interchangeable core housing in the lock to seat in. The Schlage 20-001 is a complete mortise cylinder that includes the compression ring and spring, so it fits a lock body prepped for a conventional threaded mortise cylinder.
18) The exit device needs a cylinder. Is a mortise cylinder the right part?
Not for a rim device. A rim cylinder mounts behind the device and drives a tailpiece: the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. A mortise cylinder such as the Schlage 20-001 drives a cam instead, the L583-476 straight cam in this case. The 20-001 is modular and converts between mortise and rim by changing the tailpiece, cam or rear housing, so one cylinder platform can carry the same keying to both the mortise lock and the rim device.
19) Can a mortise cylinder replace the cylinder in a keyed lever or knob?
No, key-in-lever and key-in-knob locks take a different cylinder body. The Falcon A23161-05 G is a key-in-lever cylinder for the RU/T series, 6-pin G keyway, keyed different with two cut keys. Kaba Ilco covers the same family with the 1539 key-in-knob and lever universal cylinder, the 1579 knob and lever cylinder for Sargent, and the 1599 key-in-knob replacement cylinder. The Schlage 20-001 also offers a G keyway, and being modular it adapts to key-in-lever and key-in-knob applications when the rear housing and tailpiece are changed.
20) We want drill resistance and patented key control. How does that change the cylinder choice?
The BEST 1CDF puts both in the core itself, a drill resistant preferred patented interchangeable core, 7-pin, brass, in the 150 series, which means the lock has to be prepped for an interchangeable core. The Schlage 20-001 carries basic security and enhanced security features and supports interchangeability between the Everest 29, Primus XP and Classic key systems, so on that platform the security level is set by which keyway and key system is specified rather than by moving to a different cylinder body.
21) The MS1847 deadlock is in a door with no lever trim. How does the key reach it?
Adams Rite handles that with a cylinder pull, which combines the pull and the keyed cylinder in one assembly. The 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, and the 4026 is a five pin tumbler cylinder pull for the Adams Rite 5017 wood door deadlock and deadlatch. Those are complete assemblies tied to a specific lock family. The Schlage 20-001 is a mortise cylinder that goes into a mortise lock body already carrying its own trim.
22) We need key control so tenants cannot get copies cut at the hardware store. Does this Schlage cylinder handle that?
It depends entirely on the keyway you order into, not the cylinder body. The modular platform supports interchangeability between Everest 29, Primus XP and Classic key systems, and the 20-001 is offered in the plain C, CE, E, EF, F, FG and G sections as well as the multi-section C123 through C345 and S123 through S345 sections. The plain C section is the classic Schlage keyway and blanks for it are cut everywhere, so if unauthorized duplication is the actual problem, order into a restricted section and set the key system up with your locksmith. Feature set on the cylinder covers basic and enhanced security.
23) What finish should I order to match the mortise locks already on our doors?
Twelve finishes are offered: 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 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 by the BHMA number rather than the name, since brass and bronze names drift between makers while 626 is 626 everywhere. Only the front housing shows once the cylinder is installed, and the front housing is available in all finishes to match the locks, so a cylinder swap does not force a trim change.
24) I need a keyed cylinder for a residential deadbolt or handleset. Is a commercial mortise cylinder the wrong part?
It is, for that opening. The Schlage 20-001 is a commercial mortise cylinder. Residential-style deadbolts and handlesets take rim type lazy motion cylinders instead: 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, and the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece. The Medeco 1065140 is a 5-pin retrofit for the Arrow JL interconnected lock and the Emtek handleset and deadbolt outside cylinder, the Emtek CY4 covers Emtek hardware directly, and the Kaba Ilco 1549 is a key-in-deadbolt cylinder.
25) One door needs to look keyed but should not lock. What goes in the hole?
The BEST 12E series dummy rim cylinder, 1-5/32 inch diameter, is built for that, with no keying behind it. The Schlage 20-001 is a keyed mortise cylinder and ships with two keys, so on an opening that has to lock and be operated by key it is the part to use, and the dummy is not an alternate for it.
