Corbin Russwin 564K59 27A1 626 – Frequently Asked Questions

1) Which keyway do I order for the Corbin Russwin 564K59 plug?
Two A keyway variations are offered, A1 and A2. Pick the one that matches the existing Corbin Russwin key blanks and master key system on the building, since the plug has to accept the keys already cut for that system. A1 and A2 are not interchangeable.
2) Can I use this plug to rekey a cylinder other than a CK4429?
No. The 564K59 plug is made specifically for CK4429 lock cylinders so it drops in without modifying the host device. For other platforms you want a cylinder built for that lock, for example the Kaba Ilco 1579 knob and lever cylinder for Sargent hardware, or the Falcon A23161-05 G key-in-lever cylinder in the 6-pin G keyway.
3) Is the Corbin Russwin 564K59 plug the same thing as a complete replacement cylinder?
No. The 564K59 27A1 is a 5 and 6-pin individual X Class cylinder plug supplied with a new tailpiece, a replacement component for CK4429 cylinders rather than a whole cylinder. If the job calls for a complete cylinder assembly instead, a full unit such as the Detex MC65 mortise cylinder, a 1-1/8 inch 6-pin with Schlage C keyway, or the Falcon A23161-05 G key-in-lever cylinder with 6-pin G keyway and two cut keys covers that. Those are complete cylinders in their own keyways, not parts that drop into a Corbin Russwin CK4429 housing.
4) We want to stop rekeying plugs and move to interchangeable cores - what replaces the 564K59 approach?
The 564K59 27A1 plug is a rekeying and servicing part: it comes in A1 and A2 keyways and fits inside the existing Corbin Russwin CK4429 cylinder. A facility standardizing on swappable cores instead would look at interchangeable core products such as the BEST 1CB Peaks 150 Series interchangeable core cylinder, the BEST 1CDF drill resistant patented 7-pin brass 150 Series core, or Schlage full size interchangeable core products like the 20-057-C in C keyway. Those let staff pull and replace a core without disassembling the cylinder, but they are a different keying platform from the Corbin Russwin X Class hierarchy.
5) What if the opening is a rim exit device rather than a CK4429 cylinder?
The Corbin Russwin 564K59 27A1 is built specifically for CK4429 lock cylinders and will not serve a rim device. For rim applications the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. The Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Choose the cam orientation the exit device requires.
6) What finishes does the Corbin Russwin 564K59 plug come in, and will it match my existing lever trim?
Two finishes: 606 satin brass and 626 satin chrome. 626 is the usual commercial standard and matches most satin chrome lever and mortise trim; 606 is for brass-finished openings. The visible face of the plug sits in the cylinder, so match it to the cylinder collar and trim already on the door.
7) What does the 27, 57, 67 or 77 design number mean when ordering this plug?
Those are the design codes carried on the order, four of them: 27, 57, 67 and 77. The catalogued model is 564K59 27A1, meaning design 27 with the A1 keyway. Specify the design number that matches the hardware family you are servicing along with the keyway and finish, since all three are separate choices on the order.
8) Is the 564K59 a genuine Corbin Russwin part or an aftermarket plug?
Genuine Corbin Russwin. It is an OEM cylinder component for commercial mechanical lock work, which matters if your facility runs restricted key control and you need the plug to stay inside the factory keying hierarchy.
9) Do I need to buy a tailpiece separately with this cylinder plug?
No, a new tailpiece ships with the plug, so it is ready to install and actuate the lock without sourcing that piece separately. You will still need to pin and key the plug to your system.
10) Will a universal key-in-knob cylinder work in place of the Corbin Russwin 564K59 plug?
They solve different problems. The 564K59 27A1 is an OEM X Class plug that preserves the existing Corbin Russwin A keyway and master key system in a CK4429 cylinder. Kaba Ilco universal replacement cylinders, such as the 1539 Series key-in-knob/lever universal cylinder, the 1599 key-in-knob replacement cylinder, or the 1579 knob and lever cylinder for Sargent, are complete aftermarket cylinders intended to replace a lock's cylinder outright. Going that route changes the cylinder, not just the plug, so the keying is set by the new cylinder.
11) Is there a Grade 1 mortise cylinder option if the door needs a new cylinder instead of a plug?
The Adams Rite 4036 mortise cylinder is a five-pin Grade 1 unit in the 4036 Series with a 1/2 inch minimum door thickness. That is a complete mortise cylinder for a new or replacement installation. The Corbin Russwin 564K59 27A1 is instead the 5 and 6-pin X Class plug that goes inside an existing CK4429 cylinder, so it is the choice when the cylinder body stays in the door and only the plug and tailpiece are being replaced.
12) What is the difference between ordering the 564K59 plug and ordering a 5-pin core like the BEST 1C5?
The BEST 1C5 is a standard 5-pin cylinder core from the Standard and Premium Cores line, a keyed core for a BEST interchangeable core housing. The Corbin Russwin 564K59 27A1 is a 5 and 6-pin individual X Class plug for CK4429 cylinders, supplied with a new tailpiece and offered in A1 and A2 keyways with 606 satin brass and 626 satin chrome finishes. One serves a BEST core housing; the other serves a Corbin Russwin CK4429 cylinder in the A keyway family.
13) Which cylinder should I use for a residential handleset or Kwikset deadbolt instead of the 564K59?
The Corbin Russwin 564K59 27A1 is a commercial part for CK4429 cylinders. For handleset and residential deadbolt retrofits, Medeco offers the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1065244 5-pin rim lazy motion cylinder with Emtek tailpiece, and the 1065140 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. Emtek also lists the CY4 cylinder as a parts item.
14) I need a non-keyed filler for an unused cylinder hole - is the 564K59 plug the right part?
No. Despite the word plug, the Corbin Russwin 564K59 27A1 is a keyed X Class cylinder plug in A1 or A2 keyway for CK4429 cylinders, not a blank filler. For a non-functioning opening, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the dummy component.
