Corbin Russwin 579K14 L1 626 – Frequently Asked Questions

1) I need a whole replacement cylinder, not just a plug. What should I look at instead?
A plug only rebuilds an existing cylinder housing. For a complete cylinder, look at a mortise or rim cylinder in the keyway your building uses: the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in Schlage C keyway, and the Schlage Commercial 20-021 and 20-022 are 6-pin rim cylinders differing only in tailpiece cam orientation (vertical versus horizontal). None of those are keyed to a Corbin Russwin L section, so if you are staying on the existing Corbin Russwin key system, keep the 579K14 plug and reuse the housing.
2) Will the 579K14 plug fit a Sargent, Schlage or Arrow lock?
No. It is cut for the Corbin Russwin CK4429 series and the L keyway family only. For other brands you need a cylinder made for them, such as the Kaba Ilco 1579 knob and lever cylinder for Sargent, or the Medeco 1065140 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handlesets and deadbolts.
3) I need a key-in-lever cylinder, not a plug. What are the alternatives to the Corbin Russwin 579K14?
The 579K14 L1 is a plug for the CK4429 cylinder, not a key-in-lever cylinder. For key-in-knob or lever service cylinders, the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, and the Kaba Ilco 1599 is a key-in-knob replacement cylinder. The Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series with a 6-pin G keyway, keyed different with two cut keys.
4) What should I use instead of the 579K14 plug if the opening needs an interchangeable core system?
The Corbin Russwin 579K14 L1 is a standard plug keyed into the CK4429 cylinder itself, so rekeying means servicing the cylinder. For a small-format interchangeable core approach, the BEST 1CB is a 150 Series interchangeable core cylinder and the BEST 1CDF is a drill-resistant patented interchangeable core in 7-pin brass, 150 Series. For full-size interchangeable core, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and two keys.
5) Will the Corbin Russwin 579K14 plug work in an Adams Rite deadlock or a Detex mortise application?
No. The 579K14 L1 plug is built for the Corbin Russwin CK4429 cylinder with an L keyway and is not a mortise cylinder. For Adams Rite MS1847 deadlock/deadlatch work, the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 uses through-screws; the 4026 is for the Adams Rite 5017 wood door deadlock/deadlatch. The Adams Rite 4036 is a Grade 1 five-pin mortise cylinder in the 4036 Series. For a Schlage C keyway mortise cylinder, the Detex MC65 is 1-1/8 inch and 6-pin.
6) What finishes does the 579K14 plug come in, and does the plug finish need to match my lock trim?
Two finishes: 606 satin brass and 626 satin chrome, and both are available in each of the L1 through L4 keyways. Only the exposed face of the plug shows once it is assembled, so match it to the cylinder collar or lock trim rather than the door hardware as a whole. 626 satin chrome is the usual pairing with satin chrome or brushed stainless trim; 606 pairs with brass.
7) Do I need to buy a tailpiece separately for this Corbin Russwin plug?
No. A new tailpiece is supplied with the plug, so it arrives as a complete ready-to-install replacement with no additional components to source.
8) Can I use an interchangeable core instead of rekeying a plug every time a tenant changes?
The 579K14 is a standard plug, so rekeying means taking the cylinder apart and repinning it. If you want cores you can swap by hand, that is a different platform: the BEST 1C Series standard 5-pin core, the BEST Peaks 1CB 150 Series interchangeable core, or Schlage's 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam. Moving to interchangeable core means new housings and a new key system, not a drop-in for CK4429 hardware.
9) What is the difference between the Corbin Russwin 579K14 plug and a Medeco retrofit cylinder?
The Corbin Russwin 579K14 L1 is an OEM plug that goes back into an existing CK4429 cylinder, matching the L keyway family in L1 through L4 and finishes 606 satin brass or 626 satin chrome. Medeco cylinders are complete retrofit units for other manufacturers' locks: the 1065140 is a 5-pin retrofit for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, the 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece, the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts.
10) If I am replacing a deadbolt cylinder rather than a CK4429 plug, what fits?
The Corbin Russwin 579K14 L1 plug is specific to the CK4429 cylinder. For deadbolt cylinder work, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder with a deadbolt function, and the Kaba Ilco 1539 and 1599 Series are also listed with a deadbolt function. On Schlage rim prep, the 20-022 is a 6-pin rim cylinder with a horizontal tailpiece cam and two keys, versus the vertical cam on the 20-021.
11) Does buying the 579K14 plug lock me into the Corbin Russwin L keyway?
Yes. The 579K14 plug is offered in the L keyway family, with L1, L2, L3 and L4 available in 606 satin brass and 626 satin chrome, so it keys into an existing Corbin Russwin L system. If a facility is standardizing on a different keyway instead, the Schlage 20-057-C is a full size interchangeable core in the C keyway with a 643E aged bronze finish, and the Detex MC65 is a 6-pin mortise cylinder in the Schlage C keyway.
12) Is this an OEM Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin. The 579K14 is an authentic OEM replacement cylinder component made to original Corbin Russwin specifications, which is what keeps it interchanging correctly with the rest of a CK4429 keying system.
13) Is the 579K14 suitable for a high-traffic commercial building or is it a residential part?
It is a commercial-grade part. Corbin Russwin rates it for commercial use in high-use lock cylinder applications, and typical installs are office buildings, schools, hospitals, government facilities, retail, warehouses and multi-tenant residential properties.
14) Is there a non-keyed option if the CK4429 opening does not need to lock?
The Corbin Russwin 579K14 L1 is a keyed standard plug for the CK4429 cylinder. Where an opening needs only the cylinder appearance without keyed operation, the BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter. The Emtek CY4 is a cylinder sold each in the Parts series.
