Sargent 10-0505 26D – Frequently Asked Questions

1) Does the Sargent 10-0505 come with a core, or do I need to order one separately?
The 10-0505 is the cylinder housing prepared for an interchangeable core. It is the shell your existing IC core drops into, so if you are building a new opening rather than swapping a damaged housing, you will need a core keyed to your system as well.
2) I need a knob and lever cylinder for a Sargent lock but not an interchangeable core version - what else works?
The Sargent 10-0505 is prepared for an interchangeable core, which is what you want when the facility runs a core-swap key control program. If you only need a conventional keyed cylinder for a Sargent knob or lever, the Kaba Ilco 1579 Series knob and lever cylinder is built for Sargent locks. It is a fixed cylinder rather than an IC housing, so cores cannot be swapped out with a control key.
3) What is the equivalent of the Sargent 10-0505 IC cylinder if the building is keyed on a BEST interchangeable core system instead of Sargent?
The Sargent 10-0505 is an L Design cylinder prepared for an interchangeable core and built for Sargent 72-Line and 7/10-Line locks, so it stays within a Sargent keying program. If the key system is BEST, the BEST 1CB Peaks 150 Series interchangeable core cylinder and the BEST 1CDF drill resistant patented 7-pin brass 150 Series core are the interchangeable core parts in that family. Match the part to the keyway family already in the building, since an IC housing and core only accept their own core format.
4) Will a Schlage 20-057 FSIC cylinder work in place of the Sargent 10-0505?
No. The Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam, and the 20-057-C is a full size interchangeable core in the Schlage C keyway. Both are rim-format parts on the Schlage core standard. The Sargent 10-0505 is an L Design cylinder for Sargent 72-Line and 7/10-Line locks, so the housing geometry and the core it accepts are different. Use the Schlage parts only on Schlage-cored openings.
5) Can I use the Sargent 10-0505 on an aluminum storefront deadlock?
No. The 10-0505 is built for Sargent 72-Line and 7/10-Line lock series. Narrow stile storefront deadlocks take their own cylinder parts: the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder for a 1/2 inch minimum door thickness, and the 4024 and 4025 cylinder pulls are made for the Adams Rite MS1847 deadlock and deadlatch. For a wood door version of the pull, the Adams Rite 4026 suits the 5017 wood door deadlock.
6) What does the L Design mean on the Sargent 10-0505 cylinder?
L Design is the cylinder format Sargent uses to match the lock's internal geometry and engagement. Ordering the L Design version means the cylinder seats and drives the lock function correctly on 72-Line and 7/10-Line hardware. A different Sargent design designation is a different part, even at the same finish.
7) What finishes can I get the Sargent 10-0505 cylinder in to match the rest of my doors?
Thirteen finishes: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B oil rubbed dark oxidized satin bronze, 10BL dark oxidized satin bronze clear coated, 14 bright nickel, 15 satin nickel, 20D dark statuary bronze lacquered, 26 bright chrome, 26D satin chrome, plus BSP black suede and WSP white suede powder coat. 26D and 10B are the usual matches on commercial openings.
8) Is an interchangeable core cylinder worth it over a standard keyed cylinder for a building I rekey often?
If you turn keys over regularly, yes. An IC housing like the 10-0505 lets a control key pull the core and drop a new one in without tools and without taking the lock apart, so a tenant change or lost-key event is a two-minute job per door instead of a locksmith visit. A conventional cylinder has to be pinned or replaced. For a door you rekey once a decade, a standard cylinder such as a Corbin Russwin 1000 Series mortise cylinder is the simpler buy.
9) My opening needs a mortise cylinder, not a Sargent lever cylinder - what should I order?
The Sargent 10-0505 is a cylinder for Sargent 72-Line and 7/10-Line locks and will not serve a mortise lock body prep. For mortise openings, the Corbin Russwin 1000 Grade 1 mortise cylinder is 1-1/2 inch with an A02 straight cam, the CR1070 is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, and the CR1080 is a 1-1/2 inch LFIC 6-pin mortise cylinder for Schlage L9000 mortise locks. Pick by the cam the lock body requires.
10) What is the difference between the Sargent 10-0505 and a BEST 1C5 core?
They are two halves of the same idea. The Sargent 10-0505 is the L Design cylinder prepared to receive an interchangeable core in Sargent 72-Line and 7/10-Line locks. The BEST 1C5 is a standard 5-pin cylinder core itself, from the BEST standard and premium core family. A core drops into a matching housing, so the two are not interchangeable with each other - order the 10-0505 when you need the Sargent housing and a BEST core when you are filling a BEST-format housing.
11) Is there a simpler replacement cylinder if I just need to rekey one knob and do not run a master key program?
The Sargent 10-0505 exists to support interchangeable core key control, where cores are swapped tool-free across a whole facility. For a single knob with no core program behind it, the Kaba Ilco 1599 key-in-knob replacement cylinder and the Ilco 1539 key-in-knob/lever universal cylinder are conventional replacements. They are pinned cylinders rather than IC housings, so rekeying means repinning rather than swapping a core.
12) I need a rim cylinder for an exit device, not the Sargent 10-0505 - what are the options?
The 10-0505 is a cylinder for Sargent 72-Line and 7/10-Line locks and is not a rim cylinder. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same with a horizontal cam; the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. Choose the tailpiece orientation and length the device chassis calls for.
13) Does a Detex MC65 or Falcon A23161-05 G cylinder substitute for the Sargent 10-0505?
Neither is a drop-in. The Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, and the Falcon A23161-05 G is a key-in-lever cylinder for the RU/T series in the 6-pin G keyway, keyed different with two cut keys. The Sargent 10-0505 is an L Design cylinder prepared for an interchangeable core in Sargent 72-Line and 7/10-Line locks, so the keyway family and the core format both differ.
14) Is the Sargent 10-0505 suitable for a high-traffic commercial building or is it residential grade?
It is a commercial part, catalogued for door hardware use in offices, schools, hospitals, government buildings, multi-tenant residential, retail, hospitality and warehouse facilities. It suits master key programs where one control key services a large door count.
15) What matches the Sargent 10-0505 if I need the same look in a dark bronze or black finish on other hardware?
The 10-0505 cylinder is offered in finishes including 10B Dark Oxidized Satin Bronze Oil Rubbed, 20D Dark Statuary Bronze Lacquered, and BSP Black Suede Powder Coat, alongside 26D Satin Chromium and 15 Satin Nickel. Among comparable cylinders, the Schlage 20-057-C full size interchangeable core is offered in 643E Aged Bronze. Finish codes are not shared between manufacturers, so verify a sample against the existing hardware before standardizing a building.
