Corbin Russwin 580K99 27A1 626 – Frequently Asked Questions

1) Which Corbin Russwin keyways can I get this X Class plug in?
The A keyway family, in two profiles: A1 and A2. Both are offered across all the lever design options, so you order the plug to match the keyway already cut into your building's keys. If your system runs a different Corbin keyway section, this plug is not the one.
2) Can I rekey the 580K99 plug into my existing Corbin Russwin master key system?
Yes, that is the point of buying the plug rather than a whole cylinder. It takes standard pinning in 5 or 6 chambers and comes in the A1 or A2 keyway, so a locksmith can pin it to your existing change and master cuts and keep the building on one key system.
3) Can I use a mortise or rim cylinder in place of the Corbin Russwin 580K99 plug?
No. The 580K99 is a replacement plug that restores key function inside existing Corbin Russwin CK4455 and CK4482 cylinders. Mortise and rim cylinders are separate threaded or rim-mounted assemblies: the Adams Rite 4036 is a five-pin mortise cylinder in Grade 1, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway, and the Schlage 20-021 and 20-022 are 6-pin rim cylinders with vertical and horizontal tailpiece cams. Those replace a cylinder, not a plug.
4) What is the difference between a cylinder plug and an interchangeable core?
The Corbin Russwin 580K99 27A1 is a plug - the keyed rotating component that goes inside an existing cylinder housing, supplied for 5 and 6-pin arrangements in A keyway. An interchangeable core is a complete keyed unit you drop in and out with a control key; the BEST 1CB 150 Series and the BEST 1CDF 7-pin drill resistant core are interchangeable cores, and the Schlage 20-057 is a full size interchangeable core rim cylinder. If your housings are not IC-prepped, the plug is the part that matches.
5) My lock is Sargent, not Corbin Russwin - what cylinder do I order?
The Corbin Russwin 580K99 27A1 plug is keyed to the Corbin Russwin A keyway and fits CK4455 and CK4482 cylinders, so it does not serve other manufacturers' locks. For Sargent knob and lever hardware, the Kaba Ilco 1579 is the cylinder made for Sargent; for Falcon RU/T series key-in-lever, the Falcon A23161-05 G is a 6-pin cylinder in G keyway supplied keyed different with two cut keys.
6) Does the 580K99 work with both 5-pin and 6-pin keying?
It does. The 580K99 X Class plug supports 5-pin and 6-pin tumbler arrangements, so a locksmith can pin it to match whichever chamber count the existing master key system uses without changing the plug.
7) What are the 27, 57 and 67 options on the Corbin Russwin 580K99?
Those are the lever design codes the plug is ordered against, and all three are available. The catalog model reads 580K99 27A1 for the 27 design with the A1 keyway. Match the design number to the lever trim already on the door so the replacement plug lines up with the existing lockset family.
8) My Corbin cylinder isn't a CK4455 or CK4482. What replacement cylinder should I look at instead?
This plug only services the CK4455 and CK4482 pre-8/93 cylinders, so a different Corbin body needs a different part. If you are replacing a whole cylinder rather than a plug, the Kaba Ilco 1539 Series key-in-knob/lever universal cylinder or the 1579, made for Sargent knob and lever locks, cover common aftermarket swaps. For rim applications, Schlage's 20-021 with a vertical tailpiece cam and the 20-022 with a horizontal cam are the usual pair.
9) Should I replace just the plug or the whole cylinder on an older Corbin lock?
Replacing the plug keeps the original cylinder shell, housing and lock body in the door, which is why locksmiths use the 580K99 on legacy CK4455 and CK4482 hardware where a full cylinder swap would mean changing trim or keying. If you would rather move away from conventional pinning entirely, an interchangeable core route such as the BEST 1C Series standard 5-pin core or the Schlage 20-057 6-pin FSIC rim cylinder lets maintenance staff rekey by pulling the core instead of disassembling the lock.
10) I need a 5-pin core rather than a plug for my keying system - what are my options?
The Corbin Russwin 580K99 27A1 covers 5 and 6-pin tumbler arrangements as an X Class plug for Corbin Russwin CK4455 and CK4482 cylinders. If your system uses BEST-style interchangeable cores instead, the BEST 1C Series standard 5-pin cylinder core is a 5-pin core unit. Keyways are not interchangeable between the two systems, so the choice follows the hardware already in the door.
11) What do I use for a deadbolt cylinder instead of the 580K99?
The 580K99 X Class plug serves Corbin Russwin CK4455 and CK4482 cylinder locks. For deadbolt applications, the Kaba Ilco 1549 is a key-in-deadbolt cylinder, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts.
12) Is the 580K99 plug suitable for high-traffic commercial doors?
It is a commercial-rated part, catalogued by Corbin Russwin as a genuine replacement component for mechanical locks, and it is the plug facilities use on office, school, healthcare and municipal openings still running pre-1993 Corbin hardware. Because it is the original manufacturer's part, the key engagement matches what the lock was built around.
13) Does the 580K99 plug come in satin chrome, and what if I need a different finish family?
The Corbin Russwin 580K99 27A1 plug is offered in 606 satin brass and 626 satin chrome, in A1 and A2 keyways. If an aged bronze appearance is required and the hardware runs a Schlage keyway, the Schlage 20-057-C full size interchangeable core is supplied in 643E aged bronze with C keyway.
14) Is a cylinder pull an alternative to the 580K99?
No - they solve different problems. The 580K99 is a keyed plug that restores operation inside a Corbin Russwin CK4455 or CK4482 cylinder. Cylinder pulls are door-mounted pull assemblies that accept a cylinder: the Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847 deadlock, the Adams Rite 4024 mounts with a trim plate for MS1847 systems, and the Adams Rite 4026 is for the 5017 wood door deadlock.
