Corbin Russwin 574K05 A1 626 – Frequently Asked Questions

1) Will the Corbin Russwin 574K05 plug fit my CK4400 series cylinder?
It fits CK4400 series cylinders with one exception: the CK4429 Hotel function is not covered. It also fits CK4455 and CK4482 cylinders. The catch is the date of manufacture, the plug is for cylinders built before August 1993. If your cylinder is later than that, this is the wrong plug.
2) Which Corbin Russwin keyways can I order this cylinder plug in?
The 574K05 plug comes in the full A keyway range: A1 through A24. Order the plug in the same keyway as the rest of your Corbin Russwin system or the existing keys will not enter, a plug is keyway-specific and cannot be re-broached in the field.
3) 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 standard plug that drops into the existing cylinder housing, so worn or re-keyed legacy cylinders can be serviced without pulling and replacing the complete cylinder assembly. That keeps the original housing, cam, and lock body in place.
4) If the whole Corbin Russwin cylinder is worn out rather than just the plug, what should be ordered instead of the 574K05 plug?
The 574K05 A1 is an individual standard plug meant to drop into an existing Corbin Russwin cylinder housing on CK4400 (except CK4429 Hotel), CK4455 and CK4482 cylinders built before 8/93, so it only helps when the housing is still serviceable. If the housing itself is damaged, you need a complete cylinder instead. Complete key-in-knob and key-in-lever replacement cylinders include the Kaba Ilco 1599 key-in-knob replacement cylinder and the Kaba Ilco 1539 key-in-knob/lever universal cylinder; for a mortise application the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway.
5) Does the 574K05 work in both 5-pin and 6-pin Corbin Russwin cylinders?
Both. The 574K05 is an individual standard plug configured for 5-pin and 6-pin arrangements, so a locksmith can pin it to whatever chamber count the existing cylinder and the building's keying system use.
6) My Corbin Russwin cylinders are newer than 1993 or are CK4429 Hotel, what do I use instead?
This plug will not serve those. It is limited to CK4400 (non-hotel), CK4455 and CK4482 cylinders made before 8/93. For an opening you are willing to convert rather than service, a full replacement cylinder is the route, for example the Kaba Ilco 1539 Series key-in-knob and lever universal cylinder or the Schlage 20-021 rim cylinder if the application is a rim device.
7) Is this plug suitable for a large facility standardizing its keying?
It is a commercial-grade replacement part, and the A1 to A24 keyway spread is what lets a school, hospital or office portfolio keep every legacy CK4400, CK4455 and CK4482 cylinder on the same master system while rebuilding worn plugs one at a time.
8) Is the 574K05 an interchangeable core like a BEST core?
No. It is a standard cylinder plug that a locksmith pins and installs into a conventional Corbin Russwin cylinder housing, not a small format core you twist out with a control key. If you want removable-core servicing you are looking at a different system entirely, such as the BEST 1C Series standard 5-pin core or the Schlage 20-057 full size interchangeable core rim cylinder.
9) Is there an equivalent plug for a Sargent knob or lever cylinder rather than Corbin Russwin?
No. The 574K05 A1 plug is cut for the Corbin Russwin A keyway family and matches CK4400, CK4455 and CK4482 cylinders, so it will not serve a Sargent cylinder. For Sargent knob and lever openings, the Kaba Ilco 1579 is a knob and lever cylinder made for Sargent, and it is supplied as a complete cylinder rather than a loose plug.
10) We want to move a building off keyed cylinders to interchangeable core so we stop rebuilding plugs. What is the alternative?
Rebuilding with the 574K05 A1 plug keeps the opening on a standard fixed cylinder, which means re-pinning by hand each time tenancy changes. A small-format interchangeable core system lets you swap the core instead: the BEST 1C series standard 5-pin core and the BEST Peaks 1CB 150 series interchangeable core cylinder both work that way, and the BEST 1CDF is a drill-resistant patented interchangeable core in 7-pin brass. On the full-size side, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam.
11) Can the 574K05 plug be used in a rim exit device cylinder?
It is not intended for that. The 574K05 A1 plug serves Corbin Russwin CK4400, CK4455 and CK4482 cylinders and is sold as a plug only, with no tailpiece or cam. Rim exit device trim takes a complete rim cylinder: 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, each supplied with 2 keys.
12) What should I use on an aluminum storefront door instead of this Corbin Russwin plug?
The 574K05 A1 rebuilds Corbin Russwin CK-series cylinders and has no application in narrow-stile storefront hardware. For those openings the Adams Rite 4036 is a Grade 1 mortise cylinder in the 4036 series with a 1/2 inch minimum door thickness, and the Adams Rite 4024 and 4025 are cylinder pulls built for the MS1847 deadlock/deadlatch, the 4025 being a five pin tumbler pull with through-screws. For a wood door the Adams Rite 4026 five pin tumbler cylinder pull suits the 5017 wood door deadlock/deadlatch.
13) What finishes does the Corbin Russwin 574K05 plug come in?
Two: 606 satin brass and 626 satin chrome. Match the plug face to the existing cylinder ring or the mismatch will show at the face of the lock, 626 is the usual choice on commercial openings already running satin chrome trim.
14) What is the difference between the 574K05 A1 plug and a Falcon A23161-05 G cylinder?
The Corbin Russwin 574K05 A1 is a 5 and 6-pin individual standard plug in the A keyway, sold as a loose component to rebuild an existing CK4400, CK4455 or CK4482 cylinder. The Falcon A23161-05 G is a complete key-in-lever cylinder for the RU/T series, 6-pin in the G keyway, keyed different and supplied with 2 cut keys. One is a rebuild part for an existing housing, the other is a finished assembly for a Falcon lever lock.
15) Will this plug work in a deadbolt?
No. The 574K05 A1 is a plug for Corbin Russwin CK4400, CK4455 and CK4482 cylinders and is not a deadbolt part. For deadbolt work, the Kaba Ilco 1549 is a key-in-deadbolt cylinder, and the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts; the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts.
16) Is there a cylinder option that looks the part but does not key, for a door we do not want locked?
The 574K05 A1 is a working plug and always operates with a key in the Corbin Russwin A keyway. If the opening only needs the appearance of a cylinder, the BEST 12E series dummy rim cylinder is a non-operating unit with a 1-5/32 inch diameter.
17) We have Emtek residential hardware in a few units alongside Corbin Russwin commercial doors. Can one plug cover both?
No. The 574K05 A1 plug is built for Corbin Russwin CK4400, CK4455 and CK4482 cylinders in the A keyway and is a commercial-grade part. Emtek hardware takes its own cylinder, the Emtek CY4, sold each; Medeco also offers the 1065244 5-pin rim lazy motion cylinder with an Emtek tailpiece and the 1065140 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder.
18) Does the 606 satin brass or 626 satin chrome finish choice on the plug need to match anything else?
The 574K05 A1 plug comes in 606 satin brass and 626 satin chrome, and since the plug face is the visible part of the cylinder, the choice should match the surrounding trim. Among comparable cylinders, the Schlage 20-057-C full size interchangeable core is offered in 643E aged bronze, so finish naming varies by maker and is worth confirming against the existing hardware rather than assumed.
