Corbin Russwin 574K05 59B1 626 – Frequently Asked Questions

1) Which Corbin Russwin lock cylinders does the 574K05 plug fit?
The 574K05 plug is built for Corbin Russwin CK4400 (with the exception of the CK4429 Hotel function), CK4455, and CK4482 series cylinders manufactured before 8/93. The date matters: if the cylinder was made after August 1993, this is the wrong plug. Pull the cylinder and confirm the series stamp before ordering.
2) What keyway and finish choices do I have to specify when ordering the 574K05?
Two things get specified: keyway and finish. Keyway is B1 or B2 within the 59B family, and finish is 606 Satin Brass or 626 Satin Chrome. Both keyways are offered in both finishes, so pick the keyway that matches your existing key system and the finish that matches the rest of the cylinder.
3) Can I just replace the plug instead of buying a whole new cylinder?
That is exactly what the 574K05 is for. It is supplied as an individual standard plug so a locksmith can service or rekey a cylinder without swapping the full cylinder assembly, which keeps the existing housing, cam and trim in place.
4) Will the 574K05 plug keep my building keyed the same way?
It will, provided you order the matching keyway. The plug carries the 59B keyway with B1 or B2 designation, so it stays inside the same key control system and can be pinned to your existing masterkey schedule. Order the wrong keyway and your existing keys will not enter.
5) Is a BEST interchangeable core the same kind of part as the Corbin Russwin 574K05 plug?
No. The 574K05 59B1 is a standard cylinder plug that goes inside a conventional Corbin Russwin cylinder in the CK4400, CK4455 and CK4482 series. The BEST 1C Series is a standard 5-pin cylinder core and the BEST Peaks 1CB is a 150 Series interchangeable core cylinder - those are removable cores that drop into IC housings and are pulled with a control key, a different servicing method entirely. An IC core cannot be fitted into a conventional Corbin Russwin cylinder shell.
6) If the whole Corbin Russwin cylinder needs replacing instead of just the plug, what should be ordered?
The Corbin Russwin 574K05 59B1 is an individual standard cylinder plug supplied as a replacement part for servicing a cylinder without replacing the full assembly, so it only helps when the existing cylinder housing stays in the door. When the complete cylinder is being swapped, a full cylinder is the right item instead - for example the Kaba Ilco 1539 Series key-in-knob / lever universal cylinder, or the Kaba Ilco 1599 key-in-knob replacement cylinder. Those are complete cylinders rather than plugs, so they do not carry the Corbin Russwin 59B keyway and will not re-key into an existing 59B system without new keys.
7) Our doors take a rim cylinder for an exit device, not a lock plug. What is the alternative?
The Corbin Russwin 574K05 59B1 is a plug for mortise-style CK4400, CK4455 and CK4482 cylinders, not a rim cylinder. For a rim application, the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the Schlage 20-022 is the same rim cylinder with a horizontal tailpiece cam. Choose the cam orientation the exit device chassis calls for.
8) We are standardizing on Schlage C keyway across the building - what replaces the Corbin Russwin plug?
The 574K05 59B1 plug is keyed to the Corbin Russwin 59B keyway, offered in B1 and B2 keyway options, so it stays within a Corbin Russwin key system. If the facility is moving to a Schlage C keyway, the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, and the Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway in 643E aged bronze. Both are complete cylinders, so the existing Corbin Russwin cylinder body comes out of the lock.
9) My cylinder is too far gone to rebuild. What can I use instead of a replacement plug?
If the housing itself is worn or damaged, a plug will not save it and you want a complete cylinder. For non Corbin Russwin openings or where you are re-keying a whole site to a new system, complete cylinders we carry include the Schlage Commercial 20-021 rim cylinder with a vertical tailpiece cam and the 20-022 with a horizontal cam, or the Kaba Ilco 1539 universal key-in-knob/lever cylinder. Note that those are not 59B keyed, so going that route means new keys for that opening.
10) Is the 574K05 plug appropriate for a CK4429 hotel function lock?
No. The Corbin Russwin 574K05 59B1 covers CK4400 series cylinders with the CK4429 Hotel function specifically excluded, along with CK4455 and CK4482 cylinders made before 8/93. Hotel function cylinders use different plug construction. For hospitality openings outside the hotel-function locks, the 574K05 remains the matching part in 606 satin brass or 626 satin chrome with a B1 or B2 keyway.
11) Will the 574K05 plug work in an aluminum storefront deadlock?
No. The Corbin Russwin 574K05 59B1 is built for CK4400 (except CK4429 Hotel), CK4455 and CK4482 series cylinders manufactured before 8/93. Aluminum storefront deadlocks use their own cylinders - the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder for a minimum 1/2 inch door thickness, and the Adams Rite 4025 is a five-pin cylinder pull with through-screws for the MS1847 deadlock/deadlatch. Those are the correct family for storefront work.
12) What is the equivalent plug for a Sargent lock rather than Corbin Russwin?
The 574K05 59B1 is specific to Corbin Russwin CK4400, CK4455 and CK4482 cylinders with the 59B keyway and will not fit another manufacturer's chassis. For Sargent knob and lever locks, the Kaba Ilco 1579 Series cylinder is made for Sargent. Note that the 1579 is a complete replacement cylinder rather than a plug, so it is a cylinder swap rather than a rebuild of the one in the door.
13) What if the opening is a deadbolt rather than a CK4400 lockset?
The Corbin Russwin 574K05 59B1 plug is intended for CK4400, CK4455 and CK4482 lock cylinders. For deadbolt openings, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, and the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Confirm the tailpiece and cam arrangement matches the deadbolt chassis before ordering.
14) Is there a higher-security alternative if key control is the concern rather than a like-for-like plug?
The 574K05 59B1 is a standard plug that keeps an existing Corbin Russwin 59B system intact, so it does not change the level of key control. If the goal is upgrading protection, the BEST 1CDF is a drill resistant preferred patented interchangeable core in 7-pin brass, 150 Series. That is a different cylinder format - an interchangeable core - so it requires an IC-prepped housing and re-keys the opening to a new system.
15) Is the 574K05 a residential part or a commercial one?
Commercial. It is a Corbin Russwin replacement cylinder part intended for commercial mechanical lock service, the kind of work done in offices, schools, healthcare and municipal buildings running legacy CK4400 or CK4455 hardware.
