Corbin Russwin 564K59 AR 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 564K59 AR, a full cylinder or just the plug?
It's the plug only, not a complete cylinder. The 564K59 AR is an Individual X Class cylinder plug made as a replacement component for the Corbin Russwin CK4429 mortise cylinder, and it ships with a new tailpiece. If your existing CK4429 housing is damaged rather than the plug, this part alone won't fix it.
2) Will the 564K59 AR plug work in a 6-pin Corbin Russwin system, or only 5-pin?
Both. The plug supports 5-pin and 6-pin configurations, so a locksmith maintaining a building that runs 6-pin masters and 5-pin change keys can stock the one part for both.
3) Does the AR keyway on this Corbin Russwin plug matter if my building is keyed to a different keyway?
Yes, and it's the thing to check first. The 564K59 plug is factory cut to the AR keyway, so keys from a different Corbin Russwin keyway will not enter it. It has to match the keyway family already in your master key system, otherwise the plug can be pinned but the building's keys still won't work.
4) If a Corbin Russwin CK4429 mortise cylinder housing is damaged rather than just needing rekeying, what complete mortise cylinder can be used instead of the 564K59 AR plug?
The 564K59 AR is only the plug, factory-keyed to the AR keyway with a new tailpiece, and it is meant as a drop-in replacement inside an existing CK4429 mortise cylinder. If the housing itself is damaged, a complete mortise cylinder is the right part instead. The Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1 in the 4036 Series, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder cut to the Schlage C keyway. Both replace the whole cylinder, so neither will carry an AR-keyway key system the way the 564K59 AR plug does.
5) We want to be able to rekey doors without disassembling cylinders the way the Corbin Russwin 564K59 AR plug requires. What should we standardize on?
The 564K59 AR is an Individual X Class plug that is swapped into a CK4429 mortise cylinder to change keying. If you want keying changes made at the door without taking a cylinder apart, an interchangeable-core platform is the alternative. The BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented interchangeable core in seven-pin brass, and the Schlage 20-057 is a six-pin FSIC rim cylinder with a convertible tailpiece cam. Those use a control key to pull the core, whereas the 564K59 AR keeps you inside the Corbin Russwin AR keyway hierarchy.
6) The cylinder needing service is in a key-in-lever lockset, not a mortise cylinder. Is the Corbin Russwin 564K59 AR the right part?
No. The 564K59 AR is built specifically for the Corbin Russwin CK4429 mortise cylinder. For key-in-lever and key-in-knob bodies, the cylinder is a different format: the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series with a six-pin G keyway, keyed different with two cut keys, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, and the Kaba Ilco 1599 is a key-in-knob replacement cylinder. Confirm which lock body is on the door before ordering.
7) What does Individual X Class mean for keying this plug into a master key system?
X Class is Corbin Russwin's keying designation, and Individual means the plug is set up to be keyed on its own within that hierarchy rather than supplied keyed alike to a group. It drops into an existing Corbin Russwin X Class master key system, which is what keeps key control intact when you're only replacing one cylinder in a facility.
8) Do I need to buy a tailpiece separately when replacing a CK4429 plug?
No. A new tailpiece comes with the 564K59 AR plug, so you're not reusing a worn tailpiece off the old plug. You will still need pins, springs and keys cut to your system, which are not part of this item.
9) Can I use this Corbin Russwin plug in a rim cylinder or an interchangeable core?
No. It's a mortise cylinder plug for the CK4429 and nothing else. For a rim application you'd want a rim cylinder such as the Schlage 20-021 (6-pin, vertical tailpiece cam) or 20-022 (horizontal cam), and for interchangeable core work a BEST 1C 5-pin core or the 1CB 150 Series core is the right family.
10) Is a Schlage 20-021 rim cylinder a substitute for the Corbin Russwin 564K59 AR?
No. The Schlage 20-021 is a complete six-pin rim cylinder with a vertical tailpiece cam, and the 20-022 is the same cylinder with a horizontal cam; both mount through a door to drive a rim exit device. The Corbin Russwin 564K59 AR is the plug that goes inside a CK4429 mortise cylinder, supporting five- and six-pin configurations on the AR keyway. Different part of the assembly and a different cylinder format, so the two are not interchangeable.
11) What cylinder do I order for a deadbolt instead of the Corbin Russwin 564K59 AR plug?
The 564K59 AR serves the CK4429 mortise cylinder, not a deadbolt. For deadbolt work, the Kaba Ilco 1549 is a key-in-deadbolt cylinder listed with a deadbolt function, and the Medeco 1075127 is a five-pin rim type lazy motion single cylinder for handlesets and deadbolts. The Medeco 1012040 is a six-pin lazy motion rim cylinder specific to Kwikset single-cylinder deadbolts.
12) Is the BEST 1C5 core an equivalent to the Corbin Russwin 564K59 AR since both are the keyed element inside a cylinder?
They fill a similar role but are not interchangeable. The BEST 1C5 is a standard five-pin cylinder core from the Standard and Premium Cores line, designed to drop into BEST interchangeable-core housings. The Corbin Russwin 564K59 AR is an Individual X Class plug for the CK4429 mortise cylinder, supporting five- and six-pin builds on the AR keyway and shipping with a new tailpiece. Each is matched to its own manufacturer's housing and keyway, so the choice follows the hardware already on the door.
13) I need a keyed cylinder for an Adams Rite MS1847 narrow stile deadlock. Does the Corbin Russwin 564K59 AR work?
No. The 564K59 AR is a replacement plug for the Corbin Russwin CK4429 mortise cylinder. For an MS1847 deadlock or deadlatch, the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 is a five-pin tumbler cylinder pull with through-screws, both designed for MS1847. For a wood door deadlock, the Adams Rite 4026 five-pin cylinder pull is designed for the 5017 wood door deadlock or deadlatch.
14) Is the Corbin Russwin 564K59 AR cross-keyable with a Sargent or Emtek system?
No. The 564K59 AR is factory-configured to the Corbin Russwin AR keyway and fits Corbin Russwin keying hierarchies through the CK4429 mortise cylinder. Other systems need their own parts: the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, the Emtek CY4 is an Emtek cylinder sold each, and the Medeco 1065244 is a five-pin rim lazy motion cylinder supplied with an Emtek tailpiece. Match the cylinder to the key system in place rather than mixing keyways.
15) Is there a five-pin retrofit cylinder option if the existing hardware is an Arrow interconnected lock rather than a Corbin Russwin mortise cylinder?
Yes, but not with the 564K59 AR, which is built for the Corbin Russwin CK4429 mortise cylinder on the AR keyway. The Medeco 1065140 is a five-pin retrofit cylinder for the Arrow JL interconnected lock and also serves as the outside cylinder on Emtek handlesets and deadbolts.
16) What finishes does the Corbin Russwin 564K59 AR plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder face already in the door, since the plug is the visible part at the keyhole. Satin chrome is the usual match for lever and mortise trim in 626, satin brass for 606 openings.
17) Is this a residential part or commercial door hardware?
Commercial. The 564K59 AR is built for commercial mechanical lock service, the kind of work done in office buildings, schools, healthcare facilities and multi-tenant properties where a Corbin Russwin keying system is already in place.
18) Is the 564K59 AR a genuine Corbin Russwin part or aftermarket?
Genuine Corbin Russwin, built to the manufacturer's own specification for the CK4429. That matters on a keyed system: an aftermarket plug can be dimensionally close and still bind or break key control in an X Class hierarchy.
19) We only need the opening to look keyed without actually locking. Does the Corbin Russwin 564K59 AR do that?
No. The 564K59 AR is a functional keyed plug for the CK4429 mortise cylinder, supplied with a new tailpiece so it operates the lock. For a non-functioning keyed appearance, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the part built for that purpose.
20) Does the finish choice on the Corbin Russwin 564K59 AR limit which door hardware it can go behind, compared with the Schlage 20-057-C?
The 564K59 AR plug is offered in 606 Satin Brass and 626 Satin Chrome, so it can be matched to brass or chrome-toned trim. The Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway supplied in 643E Aged Bronze. Because the plug sits in the CK4429 mortise cylinder, only its exposed face shows, so finish selection is about matching the surrounding trim.
