Sargent C10-1 NA 15 – Frequently Asked Questions

1) Which Sargent locksets does the C10-1 NA cylinder fit?
The Sargent C10-1 NA is built for Sargent 10-Line, 7-Line and 65-Line locksets. It is a factory replacement cylinder for those three lock lines, so if the lock on the door is one of them, this is the matching cylinder. It is not intended for other Sargent series or for other brands' locks.
2) What does the restricted NA keyway mean for key control in my building?
NA is a restricted Sargent keyway, which means key blanks are controlled rather than sold over the counter. For a school, hospital or office running a key control program, that limits unauthorized duplication of keys cut for these cylinders. The practical consequence: your existing NA-keyed Sargent keys will work in it once it is keyed into the system, but keys for a standard open keyway will not.
3) What is the closest aftermarket alternative to a Sargent C10-1 NA knob and lever cylinder?
The Sargent C10-1 NA is a factory replacement cylinder for Sargent 10-Line, 7-Line and 65-Line locksets with a restricted NA keyway. The nearest aftermarket equivalent is the Kaba Ilco 1579 Series knob and lever cylinder, which Ilco builds specifically for Sargent locks. The trade-off is key control: the NA keyway is a restricted Sargent keyway intended to limit unauthorized key duplication, which an open aftermarket cylinder will not give you.
4) I need a cylinder for a rim exit device, not a Sargent knob or lever - what should I order instead?
The C10-1 NA is built for Sargent 10-Line, 7-Line and 65-Line lock cylinders and will not serve a rim exit device. For rim applications, look at the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam, the Schlage 20-022 with a horizontal tailpiece cam, or the Corbin Russwin 3070 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. Match the tailpiece orientation and length to what your exit device chassis calls for.
5) What should I use if I need a mortise cylinder rather than a key-in-lever cylinder?
The Sargent C10-1 NA is a key-in-lever style replacement cylinder for Sargent 10-Line, 7-Line and 65-Line locksets, so it does not thread into a mortise lock case. For mortise bodies, the Corbin Russwin 1000 Grade 1 mortise cylinder is offered in a 1-1/2 inch length with an A02 straight cam, the Corbin Russwin 1070 Grade 1 housing in 1-1/4 inch 6-pin with an A01 cloverleaf cam, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway. Pick the cam to suit your lock case.
6) Is the C10-1 NA an interchangeable core cylinder?
No. It is a conventional replacement cylinder for Sargent 10-Line, 7-Line and 65-Line locks, keyed on the restricted NA keyway. If your facility is standardized on small format or large format interchangeable cores so maintenance can swap cores without pulling the lock, look at a core product instead, such as the BEST 1C Series 5-pin core or the Schlage 20-057 FSIC rim cylinder.
7) I manage a building with dozens of Sargent locks. Can I standardize on this cylinder across all of them?
Across 10-Line, 7-Line and 65-Line Sargent locks, yes: one cylinder part number covers all three lines, so a single replacement part serves those openings and can all be keyed to the same NA system. Openings running a different Sargent series, or another brand entirely, need their own cylinder.
8) If I want interchangeable core instead of a fixed cylinder, what are my options?
The C10-1 NA is a conventional factory replacement cylinder keyed on Sargent's restricted NA keyway, so rekeying means pinning the cylinder. If you want cores you can swap with a control key, the BEST 1C Series standard 5-pin core and the BEST Peaks 1CB 150 Series interchangeable core are small-format options, the BEST 1CDF is a drill-resistant patented 7-pin brass core, and the Schlage 20-057 is a 6-pin full-size interchangeable core rim cylinder with a convertible tailpiece cam. Note these run on their own keyways, so they will not key into an existing Sargent NA system.
9) Will a Kaba Ilco 1539 or 1599 cylinder work in place of the Sargent C10-1 NA?
They are not the same fit. The Sargent C10-1 NA is matched to Sargent 10-Line, 7-Line and 65-Line lock chassis. The Kaba Ilco 1539 is a key-in-knob and lever universal cylinder and the 1599 is a key-in-knob replacement cylinder, both listed with a deadbolt function; the Ilco part cut specifically for Sargent knob and lever locks is the 1579 Series. If you are staying with Sargent chassis, the C10-1 NA or the 1579 are the parts to look at.
10) We have aluminum storefront doors with Adams Rite hardware - can I standardize on the Sargent C10-1 NA?
No. The C10-1 NA is built for Sargent 10-Line, 7-Line and 65-Line locksets. Adams Rite storefront hardware takes its own parts: the 4036 mortise cylinder is a Grade 1 five-pin cylinder for doors 1/2 inch minimum thickness, while the 4024 and 4025 cylinder pulls are made for the MS1847 deadlock/deadlatch and the 4026 cylinder pull suits the 5017 wood door deadlock. Keep a separate cylinder line for the storefront openings.
11) What is a higher-security alternative if the restricted NA keyway is not enough for our facility?
The Sargent C10-1 NA already uses a restricted NA keyway to limit unauthorized key duplication in commercial key control programs. If you want a patented, drill-resistant platform, the BEST 1CDF is a drill resistant preferred patented interchangeable core in 7-pin brass, 150 Series. Moving to it means converting the lock to accept an interchangeable core and starting a separate key system rather than extending your Sargent NA system.
12) What looks like a cylinder substitute but will not actually lock the door?
Watch the dummy and pull parts. The BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter and fills a cylinder hole without operating a lock, and the Adams Rite 4024 and 4025 are cylinder pulls tied to the MS1847 deadlock/deadlatch rather than drop-in lock cylinders. The Sargent C10-1 NA is a working replacement cylinder with a restricted NA keyway for 10-Line, 7-Line and 65-Line locksets.
13) What finish does the Sargent C10-1 NA cylinder come in?
One finish: 15, satin nickel plated and clear coated. The clear coat adds corrosion resistance. If the rest of your Sargent trim on the opening is satin chrome or brushed nickel, 15 reads as a close visual match; against bright brass or oil-rubbed bronze trim it will stand out.
14) Is this cylinder suitable for high-traffic commercial doors or is it a residential part?
Classified as a commercial product, and the finish is a plated clear coat chosen for corrosion and wear resistance in high-traffic use. Typical placements are office buildings, schools, healthcare, government facilities, retail, warehouses and multi-tenant residential.
15) I need a cylinder for a residential-style handleset or Kwikset deadbolt, not a Sargent commercial lever - what fits?
The C10-1 NA is classified as a commercial replacement part for Sargent 10-Line, 7-Line and 65-Line locksets. For handleset and deadbolt retrofits, Medeco offers the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1065244 5-pin lazy motion rim cylinder with Emtek tailpiece, and the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
16) Is there an equivalent replacement cylinder for Falcon key-in-lever locks?
The Sargent C10-1 NA only addresses Sargent 10-Line, 7-Line and 65-Line lock chassis. For Falcon, the A23161-05 G is a key-in-lever cylinder for the RU/T Series with a 6-pin G keyway, supplied keyed different with two cut keys. The two are not interchangeable, so specify by the lock brand already hanging on the door.
