Corbin Russwin 574K05 59A1 626 – Frequently Asked Questions

1) Is the 574K05 a complete cylinder or just the plug?
Just the plug. It is an individual standard plug supplied as a single unit, so you can swap the plug into an existing cylinder shell instead of replacing the whole cylinder assembly. Pins, springs, cylinder body and keys are separate items.
2) What keyway is the Corbin Russwin 574K05 plug cut for, and will it accept my existing keys?
It is cut to the 59A1 keyway. Keys from a 59A1 system will enter it once the plug is pinned to your combination; a plug from a different Corbin Russwin keyway family will not take your 59A1 keys, so match the keyway before ordering.
3) Is this plug suitable for a hotel-function Corbin Russwin lock?
No. The CK4429 Hotel function is specifically excluded from the 574K05's compatibility list, even though the rest of the CK4400 series is covered. Hotel-function cylinders use different internal arrangements, so source the plug called out for that function instead.
4) Will a BEST 1C5 core work in a Corbin Russwin CK4400 lock?
No. The BEST 1C5 is a standard 5-pin cylinder core from the Standard and Premium Cores line, built for BEST interchangeable-core housings. The Corbin Russwin 574K05 is a 5 and 6-pin individual standard plug cut to the 59A1 keyway for CK4400 series (except CK4429 Hotel), CK4455, and CK4482 locks made before August 1993. They are different cylinder platforms and different keyways, so the BEST core is not a drop-in for CK-series hardware.
5) If the whole cylinder is worn out rather than just the plug, what should be used instead of a Corbin Russwin 574K05?
The Corbin Russwin 574K05 is an individual standard cylinder plug, a replacement part meant to restore a cylinder without changing out the full assembly. When the housing itself is damaged, a complete cylinder is the right call instead: the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder in a 6-pin G keyway supplied keyed different with two cut keys. Both replace the cylinder as a unit rather than just the plug.
6) Can I use the 574K05 plug on both 5-pin and 6-pin keying?
Yes. The plug is cut for 5-pin and 6-pin arrangements, so it drops into either keying setup on compatible Corbin Russwin cylinders. Pin count follows whatever your existing keying system uses.
7) What finishes does the 574K05 cylinder plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the existing lever or knob trim so the visible plug face doesn't stand out on the door.
8) I need to rekey a school or office building full of old Corbin Russwin CK-series locks. Does replacing plugs keep my master key system intact?
That is exactly what this part is for. Swapping the 574K05 plug lets you restore or rekey a damaged cylinder while staying inside the same 59A1 keying system, so existing master and change keys keep working across the rest of the facility. It is a commercial replacement part used in locksmith and facility maintenance rekeying work on office, education, healthcare, and government buildings.
9) My Corbin Russwin lock is newer than 1993 and this plug won't fit. What else can I use?
For post-8/93 CK-series hardware you need the plug or cylinder specified for that production run, not the 574K05. If you are willing to change the cylinder rather than the plug, replacement key-in-knob and key-in-lever cylinders are a common route: the Kaba Ilco 1539 Series key-in-knob/lever universal cylinder is one option, and for rim applications the Schlage 20-021 (vertical tailpiece cam) or 20-022 (horizontal tailpiece cam) 6-pin rim cylinders are stocked. Changing cylinder families means rekeying to that family's keyway.
10) Is a cylinder plug the same thing as an interchangeable core?
No, and they are not interchangeable. The 574K05 is a plug that goes inside a conventional Corbin Russwin cylinder and has to be pinned at the bench. An interchangeable core, such as the BEST 1C Series standard 5-pin core or the BEST 1CB 150 Series core, pulls out with a control key and drops back in with no disassembly. If your doors are already set up for cores, you want a core; if they are legacy CK-series conventional cylinders, the plug is the correct repair part.
11) What is the difference between the Corbin Russwin 574K05 and a Schlage 20-057 FSIC cylinder?
The Schlage Commercial 20-057 is a 6-pin full-size interchangeable core rim cylinder with a convertible tailpiece cam and two keys, so the core is pulled and swapped with a control key. The Corbin Russwin 574K05 is a 5 and 6-pin individual standard plug in the 59A1 keyway, pinned into an existing conventional cylinder to preserve a legacy CK4400, CK4455, or CK4482 keying system. One is an interchangeable-core rim assembly; the other is a component inside a conventional cylinder.
12) Is there a mortise cylinder option instead of rebuilding a plug like the 574K05?
Yes, if the opening allows a full cylinder change. The Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1 with a 1/2 inch minimum door thickness. Either replaces the cylinder outright, which means rekeying to a new keyway rather than keeping the 59A1 keying the 574K05 plug maintains.
13) For a deadbolt cylinder replacement, is the Corbin Russwin 574K05 the right part?
No. The 574K05 plug is specified for CK4400 series (except CK4429 Hotel), CK4455, and CK4482 lock families made before August 1993. For deadbolt work, 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.
14) What looks like a substitute for the 574K05 but is not?
Cylinder pulls and dummy cylinders are the usual mix-up. The BEST 12E Series is a dummy rim cylinder with a 1-5/32 inch diameter and carries no working plug, and the Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847 deadlock. Neither is a keyed plug for a Corbin Russwin conventional cylinder; the 574K05 is a 5 and 6-pin standard plug in the 59A1 keyway.
15) Is the 574K05 plug rated for residential use or commercial only?
It is a commercial part, built to Corbin Russwin's commercial-grade tolerances for CK-series mechanical locks. Nothing stops it working in a residential setting, but it is specified for commercial door hardware duty.
16) Does the Corbin Russwin 574K05 come in a chrome finish, and how does that compare with other cylinder finishes?
The Corbin Russwin 574K05 plug is offered in 606 Satin Brass and 626 Satin Chrome, so it can be matched to existing CK-series trim. Among comparable cylinders, the Schlage Commercial 20-057-C full size interchangeable core is specified in 643E Aged Bronze with a C keyway, a darker finish on a different cylinder platform.
