Corbin Russwin 580K99 27B1 626 – Frequently Asked Questions

1) What is the difference between the B1 and B2 keyway options on this Corbin Russwin plug?
B1 and B2 are two different blade profiles within the Corbin Russwin B keyway family, and they are not interchangeable. The plug is bored and milled for one or the other, so order the one that matches the keys already cut for your system. Both are offered in 606 Satin Brass and 626 Satin Chrome.
2) What does the pin depth number (27, 57, 67) mean when ordering a Corbin Russwin X Class cylinder plug?
Pin depth identifies the plug's bottom pin chamber setup, and three are offered: 27, 57 and 67. A locksmith matches this to the existing X Class keying records so the plug pins up to the keys already in the system. Get it wrong and the plug will not accept your operating or master key even with the correct B keyway.
3) Is the 580K99 a complete cylinder or just the plug?
Just the plug. This is the cylinder plug (the rotating key-bearing core piece) for a Corbin Russwin CK4455 or CK4482 cylinder, sold as a replacement part. If you need a whole cylinder rather than a component, look at a complete mortise or rim cylinder instead, such as the Detex MC65 mortise cylinder or the Schlage 20-021 rim cylinder.
4) We want to stop rebuilding plugs and move to interchangeable cores - what would we switch to?
The 580K99 27B1 is a replacement plug that keeps a legacy Corbin Russwin CK4455 or CK4482 cylinder in its original keying system. If the goal is to rekey by swapping cores instead, the BEST 1C Series is a standard 5-pin interchangeable cylinder core, the BEST 1CB is a 150 Series interchangeable core cylinder, and the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Those are a different keying architecture, so the existing Corbin Russwin B keyway keys will not carry over.
5) I need a cylinder for an aluminum storefront deadlock, not a Corbin Russwin plug - what should I order?
The 580K99 27B1 is a plug for Corbin Russwin CK4455 and CK4482 cylinder bodies and has no application in a storefront deadlock. For Adams Rite MS1847 deadlock and deadlatch systems, the 4024 is a cylinder pull with trim plate mounting and the 4025 is a five pin tumbler cylinder pull with through-screws. For a wood door with an Adams Rite 5017 deadlock or deadlatch, the 4026 five pin tumbler cylinder pull is the matching part, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder for doors 1/2 inch minimum thickness.
6) Can this plug be used in both 5-pin and 6-pin Corbin Russwin cylinders?
Yes. The 580K99 plug is made for both 5-pin and 6-pin arrangements within the X Class system, so a single part number covers either chamber count in a compatible CK4455 or CK4482 housing.
7) I am maintaining a legacy Corbin Russwin master key system in a school. Will replacing the plug break my keying?
No, that is the point of this part. The 580K99 is an Individual X Class plug, so specifying the correct B1 or B2 keyway and the matching pin depth (27, 57 or 67) lets you rebuild the cylinder inside the existing master key hierarchy rather than rekeying the building. It is a commercial-grade part, which is what pre-1993 CK-series hardware in schools, hospitals and municipal buildings was installed with.
8) My Corbin Russwin cylinders are not CK4455 or CK4482. What should I use instead?
Don't force this one. The 580K99 27B1 plug is specific to CK4455 and CK4482 pre-August-1993 cylinders. For a different housing you need the plug matched to that cylinder, or a complete replacement cylinder. Interchangeable-core routes are a different architecture entirely, for example the BEST 1C 5-pin standard core or the Schlage 20-057 FSIC rim cylinder, and neither drops into a Corbin CK housing.
9) Which option gives higher key control than the Corbin Russwin 580K99 27B1 B keyway plug?
The 580K99 27B1 is an Individual X Class plug in the B keyway, which keeps key control inside the existing Corbin Russwin system on CK4455 and CK4482 cylinders. If you are specifying new key control rather than maintaining the old system, the BEST 1CDF is a drill resistant preferred patented interchangeable core in a 7-pin brass 150 Series build, and the BEST Peaks 1CB is a 150 Series interchangeable core cylinder. Both are separate key systems and will not operate existing B keyway keys.
10) Can I use a Detex MC65 mortise cylinder instead of rebuilding the Corbin Russwin cylinder with a 580K99 plug?
The Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder cut to the Schlage C keyway, so it is a whole-cylinder replacement on a different key system - existing Corbin Russwin B keyway keys will not operate it. The 580K99 27B1 plug preserves the original keying by rebuilding the CK4455 or CK4482 cylinder you already have, and is offered in 606 satin brass and 626 satin chrome in B1 and B2 keyways.
11) My Corbin Russwin deadbolt needs a cylinder, not a CK plug - what are the options?
The 580K99 27B1 only serves Corbin Russwin CK4455 and CK4482 cylinder bodies. For deadbolt cylinders, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder and the 1579 Series is a knob and lever cylinder for Sargent, both catalogued for deadbolt function. Medeco also lists the 1012040, a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1075127, a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
12) Which finishes does the Corbin Russwin 580K99 27B1 plug come in, and does it matter for a plug?
Two: 606 Satin Brass and 626 Satin Chrome, both available with B1 or B2 keyway and pin depth 27, 57 or 67. The plug face is visible at the keyway, so pick the finish that matches the surrounding cylinder and trim on the other doors in the building.
13) Is the BEST 12E dummy rim cylinder a cheaper stand-in for a keyed Corbin Russwin plug?
No. The BEST 12E Series is a dummy rim cylinder with a 1-5/32 inch diameter - it fills the prep and does not key or operate a lock. The Corbin Russwin 580K99 27B1 is a working keyed plug for CK4455 and CK4482 cylinders built before August 1993, so use the dummy only where an opening needs the appearance of a cylinder with no locking function.
14) Do Medeco or Emtek retrofit cylinders cross over to the Corbin Russwin 580K99 27B1?
They do not. The Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece, and the Emtek CY4 is sold as a single cylinder part for Emtek hardware. All three serve Arrow and Emtek housings. The Corbin Russwin 580K99 27B1 plug is dedicated to CK4455 and CK4482 cylinders in the B keyway.
