Sargent C10-1 SE 15 – Frequently Asked Questions

1) Which Sargent lock lines does the C10-1 SE replacement cylinder fit?
The Sargent C10-1 SE is built for Sargent 10-Line, 7-Line, and 65-Line commercial locks. It drops into those lock bodies as a direct cylinder replacement, so you restore key function without pulling and replacing the whole lockset. If the lock on your door is a different Sargent series, this is not the cylinder for it.
2) What keyway does the Sargent C10-1 SE come in, and will it work in my existing Schlage E master key system?
It is factory configured with the Schlage E keyway, so it can be pinned into an existing keying or master key program built on Schlage E. That is the point of the SE suffix: you get a Sargent cylinder that takes a Schlage E key blank rather than a Sargent keyway, which is what lets a facility on Schlage E keep one key system across mixed hardware.
3) I need a mortise cylinder, not a knob cylinder. Is the Sargent C10-1 SE the right thing?
No. The C10-1 SE is a replacement cylinder for Sargent 10, 7 and 65-Line lock bodies, not a standalone mortise housing. If you need a mortise cylinder, look at the Corbin Russwin 1000 Series 1-1/2 inch with an A02 straight cam, the Corbin Russwin 1070 1-1/4 inch 6-pin with an A01 cloverleaf cam, or the Adams Rite 4036 five-pin Grade 1 mortise cylinder. Match the cam to the lock you are feeding.
4) What is the aftermarket alternative to a Sargent C10-1 SE knob and lever cylinder?
The Kaba Ilco 1579 is a knob and lever cylinder built for Sargent locks, so it is the common aftermarket route when an OEM Sargent cylinder is not the requirement. The Sargent C10-1 SE is the genuine Sargent replacement cylinder for the 10-Line, 7-Line and 65-Line lock series, factory configured with the Schlage E keyway. Choose the C10-1 SE when the job calls for an OEM part matched to Sargent's own lock lines; the Ilco 1579 is the generic-brand equivalent for the same knob and lever application.
5) I need a cylinder for a deadbolt, not a Sargent lever lock - what should I order instead?
The Sargent C10-1 SE is a replacement cylinder for the Sargent 10-Line, 7-Line and 65-Line lock series and will not serve a deadbolt. For deadbolt work, the Kaba Ilco 1549 is a key-in-deadbolt cylinder and the Kaba Ilco 1539 universal key-in-knob / lever cylinder is also listed with a deadbolt function. Match the cylinder to the lock body you are actually servicing rather than to the finish.
6) Our building keys on Schlage C, not Schlage E - what mortise cylinder matches that keyway?
The Sargent C10-1 SE ships factory configured with the Schlage E keyway. If your master key system runs Schlage C, the Detex MC65 is a 6-pin commercial grade mortise cylinder with the Schlage C keyway at 1-1/8 inch, and the Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway. Keyway must match the system before anything else on the order.
7) Will a Sargent C10-1 SE work on an aluminum storefront deadlock?
No. The Sargent C10-1 SE is a replacement cylinder for Sargent 10-Line, 7-Line and 65-Line commercial locks. For narrow stile storefront work, the Adams Rite 4036 mortise cylinder is a Grade 1 five-pin cylinder with a 1/2 inch minimum door thickness, and the Adams Rite 4024 and 4025 cylinder pulls are made for the MS1847 deadlock and deadlatch. Glass front installers should be ordering from that group, not from the Sargent cylinder line.
8) Is the Sargent C10-1 SE a genuine OEM part or an aftermarket cylinder?
Genuine Sargent. It is sourced as an authentic Sargent lock part, which is what gets you correct fit, finish, and cam operation in the 10, 7, and 65-Line lock bodies. An aftermarket alternative for Sargent knob and lever locks is the Kaba Ilco 1579 Series knob and lever cylinder, which Ilco lists as for Sargent.
9) Can I use the Sargent C10-1 SE in an exit device rim application?
No. This is a cylinder for Sargent 10, 7 and 65-Line lock bodies, not a rim cylinder with a tailpiece for an exit device. For rim work, the Schlage 20-021 with a vertical tailpiece cam, the 20-022 with a horizontal tailpiece cam, or the Corbin Russwin 3070 6-pin rim housing with a 1-7/8 inch tailpiece are the correct types.
10) My facility uses interchangeable cores. Is the Sargent C10-1 SE an IC cylinder?
No. The C10-1 SE is a conventional replacement cylinder configured with a Schlage E keyway, not a small or full size interchangeable core. If you are running an IC program and want to keep tool-free rekeying, look instead at a BEST 1C Series 5-pin core, the BEST 1CB Peaks 150 Series interchangeable core, or a Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam.
11) Do I have to replace the whole Sargent lockset if the cylinder is worn or I need to rekey to a new system?
No, and that is the reason this part exists. Swapping in the C10-1 SE restores lock function on a 10, 7 or 65-Line Sargent lock without touching the chassis, trim, or door prep, so a maintenance crew can cut downtime on an occupied opening and keep the existing hardware in place.
12) Can I use a Schlage 20-021 rim cylinder in place of the Sargent C10-1 SE?
No. The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam, and the 20-022 is the same cylinder with a horizontal tailpiece cam - both are rim cylinders intended for rim-mounted devices. The Sargent C10-1 SE is the replacement cylinder for Sargent 10-Line, 7-Line and 65-Line locks. The two mount differently and are not interchangeable, so order by the lock body the cylinder threads into.
13) We want to move our Sargent openings onto an interchangeable core system - what takes the place of the C10-1 SE?
The Sargent C10-1 SE is a fixed replacement cylinder for the 10-Line, 7-Line and 65-Line locks, so keys are rekeyed at the cylinder. If you want cores your staff can pull and swap, the BEST 1C Series standard 5-pin core and the BEST Peaks 1CB 150 Series interchangeable core are the interchangeable-core products, and the BEST 1CDF is a drill-resistant patented 7-pin interchangeable core in brass. Converting means the lock must be prepped to accept an interchangeable core.
14) What is the difference between the Sargent C10-1 SE and a Falcon A23161-05 G key in lever cylinder?
Both are key in lever style replacement cylinders. The Sargent C10-1 SE is Sargent's own part for the 10-Line, 7-Line and 65-Line series in the Schlage E keyway, supplied in 15 Satin Nickel Plated Clear Coated. The Falcon A23161-05 G is for the RU/T series, 6-pin in the G keyway, keyed different and supplied with two cut keys. Pick by the lock brand on the door and by which keyway your system runs.
15) What finish does the Sargent C10-1 SE cylinder ship in?
One finish: 15, satin nickel plated with clear coat. The clear coat is there for corrosion resistance and to hold the satin appearance. If the rest of your trim is bright brass or oil rubbed bronze, the face of this cylinder will not match, which matters on a lever or knob where the cylinder is visible.
16) Is the Sargent C10-1 SE suitable for commercial buildings or is it a residential part?
Commercial. It is catalogued and built for commercial-grade duty, and the typical uses are offices, schools, hospitals, retail, government buildings, multi-tenant residential, and warehouses. For a property manager standardizing cylinders across a building already running Sargent 10-Line hardware, this is the maintenance part for that program.
17) Is a BEST 12E dummy rim cylinder an acceptable stand-in for the Sargent C10-1 SE?
No. The BEST 12E Series is a dummy rim cylinder at 1-5/32 inch diameter, meaning it fills the hole and carries no keyed operation. The Sargent C10-1 SE is a working keyed replacement cylinder for Sargent 10-Line, 7-Line and 65-Line locks. Use a dummy only on an inactive leaf or a decorative opening where no key function is wanted.
18) What replaces the C10-1 SE on a residential handleset or Emtek deadbolt?
The Sargent C10-1 SE is a commercial part for Sargent 10-Line, 7-Line and 65-Line locks and is not the item for a residential handleset. For that work the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece, and the Emtek CY4 cylinder is sold each.
