Corbin Russwin 580K99 57C1 626 – Frequently Asked Questions

1) What keyway options does the Corbin Russwin 580K99 plug come in?
It's machined for the 57C keyway family, ordered as either C1 or C2. Both are offered in 606 satin brass and 626 satin chrome. The plug has to match the keyway of the keys already in service on the building, so pull an existing key and confirm the section before you pick C1 or C2.
2) Will a Schlage 20-021 rim cylinder work in place of a Corbin Russwin 580K99 cylinder plug?
No. The Corbin Russwin 580K99 is a 5 and 6-pin individual X Class cylinder plug, a component that goes inside a CK4455 or CK4482 cylinder built before 8/93, cut for the 57C keyway. The Schlage 20-021 is a complete 6-pin rim cylinder with a vertical tailpiece cam and two keys, so it replaces an entire cylinder mounted through the door rather than the plug inside an existing Corbin Russwin housing. If your CK4455 or CK4482 housing is sound and you only need to restore the keyed plug, the 580K99 is the part; if the whole cylinder is being changed out to a rim application, a rim cylinder is the direction to look.
3) What is the difference between replacing a plug like the Corbin Russwin 580K99 and swapping an interchangeable core?
The Corbin Russwin 580K99 is an individual X Class plug for CK4455 and CK4482 cylinders made before August 1993, so rekeying means disassembling the cylinder and fitting the plug, which is locksmith work at the bench or in the door. An interchangeable-core product such as the BEST 1CB, a 1CB Series 150 interchangeable core cylinder, or the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam, is designed so the core pulls with a control key and a new core drops in. Facilities that expect frequent tenant turnover often standardize on interchangeable cores; sites already built on legacy Corbin Russwin CK4455 and CK4482 cylinders use the 580K99 to keep the original assemblies in service.
4) I need a complete mortise cylinder, not a plug. What should I look at instead of the Corbin Russwin 580K99?
The 580K99 is a cylinder plug only, intended for Corbin Russwin CK4455 and CK4482 cylinder assemblies. For a complete mortise cylinder, 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 Grade 1 five-pin mortise cylinder in the 4036 Series with a 1/2 inch minimum door thickness. Both are full cylinders with their own keyway, so they will not key into an existing Corbin Russwin 57C system the way the 580K99 plug does.
5) Do keys come with the 580K99 cylinder plug?
No keys are part of it. The 580K99 is the bare X Class plug for a CK4455 or CK4482 cylinder, so your locksmith pins and cuts keys to the existing system. If you need a cylinder that arrives with cut keys, a Schlage 20-021 rim cylinder ships with 2 keys and a Falcon A23161-05 G key-in-lever cylinder comes keyed different with 2 cut keys.
6) Can I use the 580K99 for both 5-pin and 6-pin keying?
Yes. The plug supports 5-pin and 6-pin configurations, so it works whether the existing Corbin Russwin cylinder is pinned to a 5-pin or a 6-pin system. You supply the pinning to match the master key system already in the building.
7) My Corbin Russwin cylinder is newer than 1993, what are my options?
The 580K99 plug won't serve you, it's cut for pre-8/93 CK4455 and CK4482 cylinders. Rather than chase a plug, most shops replace the whole cylinder on newer locks. Full-size interchangeable core options like the Schlage 20-057 FSIC rim cylinder or a BEST 1C 5-pin core let you re-key by swapping the core instead of rebuilding a plug, though changing keyway means re-keying the building.
8) Is the BEST 1C5 cylinder core an equivalent to the Corbin Russwin 580K99 plug?
They fill different roles. The BEST 1C5 is a standard 5-pin interchangeable cylinder core from the Standard and Premium Cores line, a self-contained core that seats in BEST-style interchangeable core housings. The Corbin Russwin 580K99 is a 5 and 6-pin individual X Class plug machined for the 57C keyway and built for CK4455 and CK4482 cylinders made before 8/93. A 1C5 core cannot be fitted into a Corbin Russwin CK4455 cylinder, and the 580K99 plug does not serve as a core.
9) Can a Kaba Ilco 1579 aftermarket cylinder substitute for a Corbin Russwin 580K99 on a CK4455 lock?
No. The Kaba Ilco 1579 is a knob and lever replacement cylinder built for Sargent locks, and the related 1539 is a key-in-knob and lever universal cylinder; those are complete aftermarket cylinders for knob and lever bodies. The Corbin Russwin 580K99 is the plug component inside a CK4455 or CK4482 cylinder produced before August 1993, cut for the 57C keyway, so it keeps a legacy Corbin Russwin assembly on its existing key system rather than replacing the cylinder outright.
10) For a high-security upgrade instead of restoring a Corbin Russwin CK4455 with a 580K99 plug, what are the options?
The 580K99 preserves the factory X Class security classification of the original CK4455 or CK4482 assembly. If the goal is to move up rather than restore, the BEST 1CDF is a drill-resistant patented interchangeable core in 7-pin brass, 1CDF Series, 150 housing style, and Medeco offers patented cylinders such as the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts. Those routes change the key system and the housing type; the 580K99 keeps the 57C keyway and the existing Corbin Russwin hardware in place.
11) My opening uses an Adams Rite deadlock. Does the Corbin Russwin 580K99 apply?
No. The 580K99 is a Corbin Russwin plug for CK4455 and CK4482 cylinders. For Adams Rite deadlock openings the cylinder hardware is matched to the lock body: the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both for the MS1847 deadlock/deadlatch, and the 4026 five pin tumbler cylinder pull is for the 5017 wood door deadlock/deadlatch. Those are aluminum-storefront and wood-door pull assemblies rather than a plug for a mortise cylinder.
12) Do the Medeco retrofit cylinders cover Corbin Russwin CK4455 mortise cylinders?
The Medeco retrofit cylinders in this range target other platforms: the 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. For a Corbin Russwin CK4455 or CK4482 cylinder built before August 1993, the 580K99 X Class plug in the 57C keyway is the like-for-like component.
13) Which finish should I order, 606 or 626?
Two finishes: 606 satin brass and 626 satin chrome. Match it to the cylinder collar and lock trim already on the door, since the plug face is the part you see when the key is out. Satin chrome is the usual pick where the surrounding trim is 626 satin chrome commercial hardware.
14) Is the 580K99 plug rated for commercial use?
It's a commercial-duty Corbin Russwin cylinder part, used in offices, schools, hospitals, government buildings, warehouses, retail and multi-tenant residential. It isn't a residential-grade component.
15) What is the difference between the Schlage 20-021 and 20-022 rim cylinders if I am moving off legacy Corbin Russwin cylinder parts?
Both Schlage commercial rim cylinders are 6-pin and ship with two keys; the 20-021 uses a vertical tailpiece cam and the 20-022 uses a horizontal tailpiece cam, so the cam orientation is matched to the exit device or rim lock behind the door. The Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway with a 643E aged bronze finish. None of these key into the 57C keyway the Corbin Russwin 580K99 plug is machined for, so moving to them means rekeying the opening to a new system.
