Schlage 21-059 S123 626 – Frequently Asked Questions

1) Will the Schlage 21-059 cylinder fit my S200 series lever lock?
That's exactly what the 21-059 is built for. It's a 6-pin key-in-lever cylinder listed as compatible with Schlage S and S200 Series levers, so it drops into that lever's cylinder pocket as a direct replacement. It ships non-handed, so there is no left or right version to specify for the door swing.
2) Can I get the 21-059 keyed alike to the other Schlage locks in my building?
Yes. Keying is a required choice on the 21-059: keyed different (the standard) or keyed alike when you want several openings on one key. There's also a key code box, so if your building already runs a code, enter it and the cylinder is cut to that existing system instead of a fresh one. Two cut keys come with the cylinder. Match the keyway to what your building uses as well, because a C keyway cylinder will not take an Everest E family key.
3) Do I need a different cylinder for a mortise lock or a rim exit device?
Yes, a key-in-lever cylinder is not a mortise or rim cylinder. The 21-059 is set up for cylindrical lever use. For a mortise lock you need a mortise cylinder with the right cam, such as the Corbin Russwin 1000 Series 1-1/2 inch with an A02 straight cam or the 1070 Series 1-1/4 inch 6-pin housing with an A01 cloverleaf cam. For a rim device, a rim cylinder with a tailpiece, like the Corbin Russwin 3070 6-pin rim housing with a 1-7/8 inch tailpiece. Schlage's modular cylinder platform does let one cylinder convert between mortise, rim, and key-in-lever by changing the tailpiece, cam, or rear housing.
4) I'm replacing a Falcon key-in-lever cylinder - can I use the Schlage 21-059 instead?
No, not as a drop-in. The 21-059 is made for Schlage S and S200 Series levers. If the lever body is Falcon, order the Falcon key-in-lever cylinder for that chassis, the A23161-05 G for RU and T Series in the 6-pin G keyway with two cut keys. For a Sargent lever, the Kaba Ilco 1579 knob and lever cylinder is the one made for that. Match the cylinder to the lock chassis first, then worry about the keyway.
5) What is the difference between the Schlage 21-059 key-in-lever cylinder and the Falcon A23161-05 G key in lever cylinder?
Both are key-in-lever cylinders, but they are built for different lock lines. The Schlage 21-059 is a 6-pin key-in-lever cylinder for Schlage S and S200 series levers, and it accepts any Schlage keyway. The Falcon A23161-05 G is a key in lever cylinder for the Falcon RU/T series, 6-pin, G keyway, keyed different, supplied with 2 cut keys. If the lever in the door is a Schlage S200, the 21-059 is the cylinder that goes in it; the Falcon part goes into a Falcon RU or T lever.
6) We want to standardize the building on interchangeable cores instead of standard cylinders. What is the alternative to the Schlage 21-059?
The 21-059 is a 6-pin standard key-in-lever cylinder, so rekeying it is a bench operation rather than a core swap. If you want to pull and replace cores in the field, look at the BEST 1CB Peaks 150 series interchangeable core cylinder, the BEST 1C series standard 5-pin cylinder core, or the BEST 1CDF drill resistant patented interchangeable core in 7-pin brass, 150 series. Corbin Russwin also makes a 1080 Grade 1 series 1-1/2 inch LFIC mortise cylinder, 6-pin, for Schlage L9000 mortise locks with an A01 Schlage L cam.
7) The opening is an aluminum storefront with an Adams Rite deadlock. Can I use the Schlage 21-059?
No. The 21-059 goes into Schlage S and S200 levers. Adams Rite narrow stile hardware takes its own cylinders: the 4036 mortise cylinder with five-pin security is Grade 1 with a 1/2 inch minimum door thickness, and for a cylinder pull on an MS1847 deadlock the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are the parts designed for it. On a wood door deadlock, the Adams Rite 4026 five pin tumbler cylinder pull is built for the 5017 wood door deadlock/deadlatch.
8) I need a replacement cylinder for a deadbolt, not a lever. Which one should I order?
The Schlage 21-059 is a lever cylinder and will not serve a deadbolt. Kaba Ilco makes the 1549 series key-in-deadbolt cylinder and the 1599 key-in-knob replacement cylinder for that side of the job. On residential handleset and deadbolt work, Medeco offers the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1065140 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder.
9) Which Schlage keyways can I order the 21-059 key-in-lever cylinder in?
Twenty-six keyways in total, all supplied 0 bitted so a locksmith cuts them to your system. Classic side: C, plus the C-family sections C123, C124, C125, C134, C135, C145, C234, C245, C345, and CE. Everest side: E, EF, F, FG, G. Everest 29 restricted sections: S123, S124, S125, S134, S135, S145, S234, S235, S245, S345. Pick the section that matches the existing keys on the building, not the one that looks closest.
10) I need the lever cylinder to match a satin chrome lever - what finishes does the Schlage 21-059 come in?
Four: 606 satin brass, 622 matte black, 626 satin chrome, and 643E aged bronze. The 626 satin chrome is the usual commercial match on Schlage S200 levers. The cylinder face is the only part that shows once it's in the lever, so match it to the lever trim rather than the door hardware elsewhere on the opening.
11) Is a 6-pin cylinder going to work if my existing Schlage system is 5-pin?
The 21-059 is built as a 6-pin cylinder. A locksmith can pin it to a 5-pin bitting on a 6-pin cylinder body, but the keyway section still has to match your existing keys. If your facility standard is genuinely a 5-pin core system rather than a Schlage keyway, look at an interchangeable core route instead, such as the BEST 1C Series standard 5-pin core.
12) Will Everest 29 and Primus XP keys work in this Schlage cylinder?
The Schlage modular cylinder platform supports interchangeability between Everest 29, Primus XP, and Classic key systems, and the 21-059 is offered in both Classic C-family sections and Everest E, F, and G family sections including the restricted S sections. What it will not do is accept a key from a different family than the section you order, so specify the keyway that matches the keys already in the building.
13) Is a rim cylinder the same thing as the Schlage 21-059?
They are different housings. The 21-059 is the key-in-lever cylinder for Schlage S and S200 levers. A rim cylinder mounts through the door behind a rim device, and that is a separate part such as the Corbin Russwin 3070 6-pin rim cylinder housing with 1-7/8 inch tailpiece or the BEST 12E series dummy rim cylinder at 1-5/32 inch diameter. If you are working on a rim exit device rather than a lever, the rim housing is what you need.
14) Which cylinder do I use on an Emtek lock instead of the Schlage 21-059?
The 21-059 is keyed to Schlage S and S200 levers. For Emtek, the Emtek CY4 cylinder is the brand's own part, and Medeco makes the 1065244 5-pin rim lazy motion rim type cylinder with an Emtek tailpiece as well as the 1065140 5-pin retrofit cylinder that covers the Emtek handleset and deadbolt outside cylinder.
15) Is a 5-pin cylinder an acceptable substitute for the Schlage 21-059?
Only if the keying system on the building is 5-pin. The Schlage 21-059 is 6-pin and ships with 2 keys. Several peer cylinders are built 5-pin, including the Adams Rite 4036 mortise cylinder with five-pin security, the BEST 1C series standard 5-pin core, and the Medeco 1075127 5-pin rim type cylinder. Pin count has to match the master key system the opening belongs to, so a 5-pin part does not drop into a 6-pin Schlage system.
16) I need a Schlage C keyway cylinder for a mortise lock on the same key system as my S200 levers. What are my options?
The Schlage 21-059 covers the lever side and is available in the C keyway among its keyway options, in finishes including 606 satin brass, 622 matte black, 626 satin chrome and 643E aged bronze. For a mortise body on the same Schlage C key, the Detex MC65 is a 6-pin commercial grade mortise cylinder built in Schlage C keyway at 1-1/8 inch. That pairing keeps the lever and the mortise opening on one keyway.
17) What is the 21-059 made of - will it hold up in a high traffic commercial corridor?
Brass and stainless steel construction, and it's specified as a commercial cylinder rather than a residential one. That's the normal commercial cylinder material set: brass for the plug and shell where the pins ride, stainless for the wear parts.
18) Does a thicker door change which Schlage cylinder I need?
For a key-in-lever application, no. Door thickness is taken up by the lock chassis, not the lever cylinder, so the 21-059 is specified by lever series and keyway. Thickness only enters the picture on the mortise side of the Schlage modular line, where six rear housing lengths cover thicker doors.
19) Do I need a working cylinder or a dummy on a door that does not lock?
The Schlage 21-059 is a keyed 6-pin cylinder and comes with 2 keys, so it is for an opening you actually key. On a door where the trim only needs to look complete, the BEST 12E series dummy rim cylinder at 1-5/32 inch diameter fills the hole without keying. Ordering a keyed cylinder for a dummy position adds a key to the system that has nothing to open.
