Sargent C10-1 SC 4 – Frequently Asked Questions

1) Which Sargent locks does the C10-1 SC replacement cylinder fit?
The Sargent C10-1 SC is built for Sargent's 10-Line, 7-Line and 65-Line lock series. It is a direct-fit service part for those families, so if the lock body on your door is one of those three lines, this is the cylinder to order. It is not a universal cylinder for other brands' knob or lever locks.
2) What keyway does the Sargent C10-1 SC cylinder come in?
SC1 keyway. That matters if you are keying alike across a building: keys and cylinders only interchange within the same keyway, so every opening you want on one key needs to be SC1 as well. Key duplication is straightforward since SC1 is a widely stocked keyway blank.
3) Is there an aftermarket alternative to the Sargent C10-1 SC knob and lever cylinder?
Yes. The Kaba Ilco 1579 is a knob and lever cylinder built for Sargent locks, so it addresses the same service job as the Sargent C10-1 SC replacement cylinder for 10-Line, 7-Line and 65-Line locks. The difference is sourcing: the C10-1 SC is a genuine Sargent lock part, while the Ilco 1579 is an aftermarket cylinder in the 1579 Series. If you are matching an existing Sargent keying system and want factory parts, stay with the C10-1 SC.
4) Can I put the Sargent C10-1 SC in an exit device that takes a rim cylinder?
No - the C10-1 SC is a replacement cylinder for Sargent 10-Line, 7-Line and 65-Line locks, which is a different housing style from a rim cylinder. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam; the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. Confirm which tailpiece orientation your device needs before ordering.
5) I need a cylinder for a Sargent mortise lock, not a knob or lever - what should I use?
The Sargent C10-1 SC is built for Sargent 10-Line, 7-Line and 65-Line lock series, so it will not serve a mortise housing application. For mortise cylinders, look at the Corbin Russwin 1000 Grade 1 mortise cylinder in 1-1/2 inch length with an A02 straight cam, the Corbin Russwin 1070 Grade 1 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, or the Adams Rite 4036 Grade 1 mortise cylinder with five-pin security. Cam style has to match the lock case you are feeding.
6) What finish is the Sargent C10-1 SC cylinder available in?
One finish only: 04 Satin Brass, clear coated. If the rest of your lever and rose trim is satin brass, the cylinder face will match. On chrome or bronze openings the brass face will read differently, so plan accordingly when you are standardizing a floor of doors.
7) My Sargent lock is worn out but the lever is fine. Do I replace the whole lock or just the cylinder?
If the lever and latch still work and the problem is keying, a lost key, or a tired cylinder plug, swapping the cylinder is the shorter job. The C10-1 SC is a purpose-built replacement cylinder for the 10, 7 and 65-Line locks and restores the locking function without pulling the lock body out of the door.
8) We use interchangeable cores across our facility. Is the C10-1 SC an IC cylinder?
No, the C10-1 SC is a conventional replacement cylinder with an SC1 keyway, not an interchangeable core. If your maintenance program is built around removable cores so you can rekey without disassembling hardware, look at a small format IC option such as the BEST 1C Series 5-pin core, or a full size interchangeable core like the Schlage 20-057 FSIC rim cylinder.
9) We want to move to interchangeable cores instead of keyed cylinders - what are the options?
The Sargent C10-1 SC is a conventional keyed replacement cylinder for Sargent 10-Line, 7-Line and 65-Line locks, so rekeying means pinning the cylinder. If you want cores you can swap in the field, the BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented interchangeable core 7-pin brass 150 Series core, and the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Interchangeable core systems require housings prepped for that core format.
10) What cylinder do I use for a deadbolt rather than a Sargent 10-Line lock?
The Sargent C10-1 SC is a replacement cylinder for Sargent 10-Line, 7-Line and 65-Line lock series. For deadbolt work, the Kaba Ilco 1549 is a key-in-deadbolt cylinder and the Kaba Ilco 1539 is a key-in-knob/lever universal cylinder, both listed with a deadbolt function; the Medeco 1075127 is a 5-pin rim-type lazy motion single cylinder for handlesets and deadbolts. Match the tailpiece to the bolt you are servicing.
11) Is a BEST 12E dummy rim cylinder an acceptable substitute for the Sargent C10-1 SC?
No. The BEST 12E is a dummy rim cylinder with a 1-5/32 inch diameter - it fills a prep and has no keyed function. The Sargent C10-1 SC is a keyed commercial replacement cylinder that restores the locking function of Sargent 10-Line, 7-Line and 65-Line hardware. Use the 12E only where you need a blank-off, not where a key has to turn.
12) I need a Schlage C keyway cylinder - does the Sargent C10-1 SC work?
The Sargent C10-1 SC uses the SC1 keyway and fits Sargent 10-Line, 7-Line and 65-Line locks, so it keys into an SC1 system rather than a Schlage-branded one. If you specifically need a Schlage C keyway cylinder, the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder with the Schlage C keyway, and the Schlage 20-057-C is a full size interchangeable core in C keyway with a 643E Aged Bronze finish.
13) What is the difference between the Sargent C10-1 SC and a Falcon A23161-05 G key-in-lever cylinder?
Both are key-in-lever style replacement cylinders, but they serve different lock families. The Sargent C10-1 SC is a commercial replacement cylinder with the SC1 keyway for Sargent 10-Line, 7-Line and 65-Line locks. The Falcon A23161-05 G is a key-in-lever cylinder for Falcon RU/T Series with a 6-pin G keyway, supplied keyed different with two cut keys. Choose by the lock brand already in the door and the keyway your system is built on.
14) Does the Sargent C10-1 SC work with an Adams Rite MS1847 deadlock?
No. The C10-1 SC is a replacement cylinder for Sargent 10-Line, 7-Line and 65-Line locks. Adams Rite MS1847 deadlock systems take their own cylinder pulls: the 4024 is a cylinder pull with trim plate mounting for the MS1847, and the 4025 is a five pin tumbler cylinder pull with through-screws for the same deadlock. For a wood door, the 4026 five pin tumbler cylinder pull suits the Adams Rite 5017 wood door deadlock/deadlatch.
15) Is the Sargent C10-1 cylinder suitable for commercial buildings or is it a residential part?
It is a commercial part. Sargent lists the C10-1 SC as commercial grade, and it is used in offices, schools, healthcare facilities, retail, government buildings, multi-tenant residential and warehouses where the existing hardware is Sargent 10, 7 or 65-Line.
16) Can the Sargent C10-1 SC be used in a residential handleset?
The C10-1 SC is specified for commercial use as a replacement cylinder for Sargent 10-Line, 7-Line and 65-Line locks, so it is not the part for a residential handleset. For that work, the Medeco 1065140 is a 5-pin retrofit cylinder for Emtek handlesets and deadbolt outside cylinders and Arrow JL interconnected locks, the Medeco 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece, and the Emtek CY4 is a single cylinder sold each.
17) If I only need the core rekeyed and not a whole cylinder, what is the lighter option?
The Sargent C10-1 SC is a complete replacement cylinder for Sargent 10-Line, 7-Line and 65-Line locks. Where the housing in the door is already an interchangeable core prep, you can change just the core - the BEST 1C is a standard 5-pin cylinder core from the standard and premium core range. That only applies if the existing housing accepts a removable core; a conventional Sargent cylinder does not.
