Corbin Russwin 579K14 D1 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 579K14 plug, and what cylinder does it go into?
The 579K14 is an individual standard cylinder plug, not a complete cylinder. It is built for the Corbin Russwin CK4429 cylinder and ships as a single plug unit, so it is what you order when you are servicing or rekeying a CK4429 rather than replacing the whole cylinder. It includes the new-style tailpiece.
2) Will the 579K14 plug work in a 6-pin cylinder, or is it 5-pin only?
Both. The 579K14 plug supports 5-pin and 6-pin configurations, so the same part covers a 5-pin CK4429 and a 6-pin one within a masterkeyed system.
3) Which Corbin Russwin D keyways can I get this standard plug in?
Four D-family keyways are offered: D1, D2, D3 and D4. Pick the one that matches the keyway already stamped on your existing Corbin Russwin cylinders, otherwise your building keys will not enter the plug.
4) I need a whole new cylinder, not just a plug. What should I be looking at instead?
If the cylinder shell is damaged or you are adding an opening, a plug will not do the job. A complete mortise cylinder such as the Detex MC65 in Schlage C keyway, 1-1/8 inch 6-pin, or the Adams Rite 4036 Grade 1 mortise cylinder covers that. For interchangeable-core standardization across a facility, BEST 1C 5-pin cores or the Schlage 20-057 full size interchangeable core are the route. Note those are different keyways and key systems from Corbin Russwin D.
5) Can a BEST 1C5 core be used in place of a Corbin Russwin 579K14 D1 plug?
No. The Corbin Russwin 579K14 D1 is an individual standard cylinder plug for the Corbin Russwin CK4429 cylinder, supplied with a new tailpiece and factory-configured for the D keyway. The BEST 1C5 is a standard 5-pin cylinder core from BEST's Standard and Premium Cores line, meaning it is a removable core that drops into BEST interchangeable-core housings, not a plug that rebuilds a CK4429 cylinder. They serve different servicing methods and are not interchangeable.
6) If the whole cylinder needs replacing instead of just the plug, what mortise cylinder can be used?
The Corbin Russwin 579K14 D1 is a replacement plug intended for targeted service of a CK4429 cylinder rather than full cylinder replacement. When the complete cylinder is being swapped, 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. Both are complete cylinders, so keying moves to their own keyways rather than staying in the Corbin Russwin D system.
7) For a rim exit device rather than a CK4429 cylinder, what should be ordered instead of the 579K14 D1?
The 579K14 D1 plug is engineered specifically for the Corbin Russwin CK4429 cylinder and will not serve a rim device. For rim applications, Schlage offers the 20-021 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 6-pin rim cylinder with a horizontal tailpiece cam, each supplied with 2 keys, so the tailpiece orientation is matched to the device.
8) What finishes does the 579K14 plug come in, and does the choice affect operation?
Two finishes: 606 Satin Brass and 626 Satin Chrome. Both are offered across all four D keyways. Finish is cosmetic here, so match it to the visible cylinder face on the door, typically 626 on commercial openings with satin chrome trim.
9) Does the 579K14 come with pins, springs or keys?
It is supplied as the standard plug itself with the new tailpiece. Plan on using your own pinning kit and cutting keys to your existing system, since the part is meant for locksmiths and maintenance shops already keying Corbin Russwin cylinders. If you need a cylinder that arrives keyed with cut keys, a complete cylinder such as the Schlage 20-021 rim cylinder ships with two keys instead.
10) Why does the tailpiece matter on this plug?
The tailpiece is what drives the lock mechanism when the key turns, so it has to match the cylinder generation. The 579K14 carries the new tailpiece design for correct engagement in compatible CK4429 assemblies. If your existing plug uses the older tailpiece, confirm you are replacing with the same style, or the key will turn without operating the lock.
11) Can I use this plug to keep new openings on the same key system as the rest of my building?
Yes, that is the point of specifying the keyway. Ordering the 579K14 in the same D-family keyway already in use (D1 through D4 are available) keeps the plug inside your existing Corbin Russwin keying and key control, so master and change keys carry over. Mixing keyways on the same building breaks masterkeying.
12) What is the difference between the Corbin Russwin 579K14 D1 plug and a Schlage 20-057 FSIC cylinder?
The 579K14 D1 is a single standard plug that supports 5-pin and 6-pin configurations and rebuilds a Corbin Russwin CK4429 cylinder in the D keyway. The Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, supplied with 2 keys; a related version, the 20-057-C, is an FSIC core in the C keyway with a 643E aged bronze finish. The Schlage parts are core-and-housing products for rim applications, while the Corbin Russwin part is a plug for cylinder-level service.
13) Is a Kaba Ilco 1539 universal cylinder an alternative to the Corbin Russwin 579K14 D1?
They are different kinds of part. The 579K14 D1 is an individual standard plug for the Corbin Russwin CK4429 cylinder, offered in 606 satin brass and 626 satin chrome with D1 through D4 keyway options. The Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, a complete cylinder assembly rather than a plug, as is the 1599 key-in-knob replacement cylinder. Choose the 579K14 D1 when the CK4429 cylinder body stays in the lock and only the plug and tailpiece are being renewed.
14) Does a Falcon A23161-05 G key-in-lever cylinder replace a Corbin Russwin 579K14 D1?
No. The Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series with a 6-pin G keyway, keyed different and supplied with 2 cut keys. The Corbin Russwin 579K14 D1 is a plug only, configured for the Corbin Russwin D keyway so existing D-system keys continue to operate the opening. Swapping to the Falcon cylinder moves that door to the G keyway.
15) What is a comparable part for a residential handleset or deadbolt instead of the Corbin Russwin 579K14 D1?
The 579K14 D1 is a commercial-grade Corbin Russwin cylinder part. For handleset and deadbolt work, Medeco offers the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1065244 5-pin lazy motion rim cylinder with an Emtek tailpiece, and the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts. Those are complete cylinders matched to specific consumer lock bodies, not plugs for a CK4429.
16) Is the Corbin Russwin 579K14 D1 an interchangeable core like the BEST 1CB or 1CDF?
No. The 579K14 D1 is an individual standard plug installed into a CK4429 cylinder during service. The BEST 1CB is a 1CB series interchangeable core cylinder in the Peaks 150 series, and the BEST 1CDF is a drill resistant patented interchangeable core 7-pin brass core in the 150 series. Interchangeable cores are pulled and replaced with a control key, whereas the Corbin Russwin plug is fitted at the bench as part of rebuilding the cylinder.
17) For a Sargent knob or lever instead of a Corbin Russwin CK4429, which cylinder applies?
The Corbin Russwin 579K14 D1 plug is built for the CK4429 cylinder in the D keyway and should not be fitted to other manufacturers' locks. For Sargent knob and lever work, the Kaba Ilco 1579 knob and lever cylinder is made for Sargent, and the Ilco 1549 is a key-in-deadbolt cylinder for deadbolt function.
18) Is this suitable for residential locks or is it a commercial part?
Commercial. The 579K14 plug is a mechanical lock service part for commercial-grade Corbin Russwin cylinders, used in offices, schools, hospitals, government buildings, multi-tenant residential and warehouses. For a residential retrofit cylinder you would look at something like the Medeco 1075127 5-pin rim type cylinder for handlesets and deadbolts.
19) What looks like a substitute for the 579K14 D1 but is not a keyed cylinder part at all?
Two cases worth ruling out. The BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is a non-keyed dummy, so it provides no key function. The Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are pull trims designed for the Adams Rite MS1847 deadlock, and the 4026 is a five pin tumbler cylinder pull for the 5017 wood door deadlock. None of those rebuild a Corbin Russwin CK4429 cylinder the way the 579K14 D1 plug does.
