Corbin Russwin 574K05 59C1 626 – Frequently Asked Questions

1) Will the Corbin Russwin 574K05 plug fit any CK4400 Series cylinder?
Not all of them. The 574K05 plug is built for CK4400 Series cylinders, but it excludes the CK4429 Hotel function and any CK4455 or CK4482 unit manufactured before 8/93. Check the date code and function on the lock before pulling the cylinder apart, because those three exceptions use a different plug.
2) Do I have to replace the whole cylinder, or can I just swap the plug?
Just the plug. The 574K05 is supplied as an individual replacement plug so a locksmith can rekey or repair a damaged CK4400 cylinder without buying the complete cylinder assembly. It is a replacement part, not a working cylinder on its own, so it arrives without pins, springs, or keys.
3) If I need a whole cylinder rather than just the plug, what should I order instead of the Corbin Russwin 574K05?
The 574K05 59C1 is an individual cylinder plug, a replacement part for rebuilding an existing CK4400 Series cylinder rather than a complete lock cylinder. When the housing itself is damaged or missing, order a complete cylinder instead: the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, and the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with two keys. Those are full cylinder assemblies, so they change the keyway from the Corbin Russwin 59C1 profile.
4) Is a BEST 1C core an equivalent to the Corbin Russwin 574K05 plug?
No. The BEST 1C is a standard 5-pin interchangeable core, a complete keyed core that drops into a BEST figure-eight housing, while the Corbin Russwin 574K05 59C1 is a bare plug for 5 and 6-pin CK4400 Series cylinder rebuilds and is pinned into an existing Corbin Russwin cylinder body. The BEST 1CB is a 1CB Series interchangeable core and the 1CDF is a drill-resistant patented 7-pin brass core in the 150 Series - all are core-based systems rather than plug-level service parts, so none of them substitutes for the 574K05 in a CK4400 cylinder.
5) For a key-in-lever lock that is not a CK4400, what replacement cylinder should I use?
The Corbin Russwin 574K05 59C1 plug is built for CK4400 Series cylinders, excluding CK4429 Hotel and CK4455 and CK4482 units made before 8/93, so it does not serve other lock families. For other key-in-knob and key-in-lever bodies, the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder, the 1579 Series is a knob and lever cylinder for Sargent, and the 1599 is a key-in-knob replacement cylinder. The Falcon A23161-05 G is a key-in-lever cylinder for the RU/T Series with a 6-pin G keyway, keyed different with two cut keys.
6) Does the 574K05 cylinder plug work in both 5-pin and 6-pin cylinders?
It does. The 574K05 is drilled for both 5-pin and 6-pin configurations, so the same plug covers a 5-pin masterkeyed job or a 6-pin system without ordering a separate part number.
7) What finishes is the Corbin Russwin 574K05 plug available in?
Two: 606 satin brass and 626 satin chrome. On a knob or lever cylinder the plug face is the visible part, so match it to the lock trim already on the door, 626 for chrome and brushed nickel openings, 606 for brass.
8) I need a complete replacement cylinder, not a plug. What should I look at instead?
If the housing is damaged or you want a drop-in unit with keys, a plug will not do the job. Whole-cylinder options include the Kaba Ilco 1539 Series key-in-knob and lever universal cylinder, the Kaba Ilco 1599 key-in-knob replacement cylinder, or, for a rim device, the Schlage 20-021 six-pin rim cylinder with vertical tailpiece cam. None of those carry the Corbin Russwin 59C keyway, so they will be on a different key system from your existing CK4400 openings.
9) Can I use this Corbin Russwin plug to convert a lock to an interchangeable core system?
No. The 574K05 is a standard plug for a conventional CK4400 cylinder, not a core. For an interchangeable core program you need core hardware instead, such as the BEST 1C Series standard 5-pin core, the BEST 1CB 150 Series interchangeable core, or the Schlage 20-057 six-pin FSIC rim cylinder. Those are a different cylinder architecture and will not accept this plug.
10) I want interchangeable core so I can rekey without pinning - what is the alternative to a 574K05 plug?
Rebuilding with the Corbin Russwin 574K05 59C1 plug means pinning a plug into the CK4400 cylinder at the bench. If the goal is field-swappable keying instead, the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam and two keys, and the 20-057-C is a full size interchangeable core in the C keyway with a 643E Aged Bronze finish. Those are FSIC systems, so the lock body has to accept an FSIC housing rather than a conventional Corbin Russwin cylinder.
11) What is the difference between the Corbin Russwin 574K05 and a deadbolt cylinder like the Kaba Ilco 1549?
The 574K05 59C1 is a commercial cylinder plug supplied on its own for targeted servicing of CK4400 Series cylinders, in 606 Satin Brass and 626 Satin Chrome with C1 and C2 keyway options. The Kaba Ilco 1549 Series is a key-in-deadbolt cylinder with a deadbolt function, and the 1539 Series is also listed for deadbolt function - complete cylinders intended for deadbolt bodies. Substituting one for the other is not possible; the plug addresses a cylinder rebuild, the Ilco parts replace a cylinder in a deadbolt.
12) Can I use a mortise cylinder such as the Adams Rite 4036 in place of the 574K05 plug?
No. The Adams Rite 4036 is a Grade 1 five-pin mortise cylinder in the 4036 Series with a 1/2 inch minimum door thickness, a threaded cylinder that screws into a mortise lock case. The Corbin Russwin 574K05 59C1 is a plug only, fitted inside a CK4400 Series cylinder shell with the 59C1 keyway profile. A mortise cylinder replaces the entire cylinder and brings its own keyway, so it is a different scope of repair.
13) Is the 574K05 a commercial part or is it for residential locks?
Commercial. It is built for Corbin Russwin mechanical lock cylinders in offices, schools, healthcare, government buildings, multi-tenant residential, warehouses, and retail, where doors see heavy daily use.
14) Is the 574K05 a genuine Corbin Russwin part or an aftermarket copy?
It is a Corbin Russwin OEM-specification component, built to the same tolerances as the plug that left the factory in the original cylinder. That matters on a masterkeyed system, where an out-of-spec plug shows up as sticky keys and shear line problems across the facility.
