Corbin Russwin 564K53 27A1 626 – Frequently Asked Questions

1) Which Corbin Russwin cylinders does the 564K53 plug actually fit?
The 564K53 plug is built for CK4400 series cylinders (the CK4429 Hotel function excepted), plus CK4455 and CK4482 cylinders manufactured before 8/93. That date cutoff is the part that trips people up: a CK4400 cylinder made after 8/93 is not covered, so check the vintage of the lock before you pull the plug.
2) Will a 564K53 plug rekey my existing Corbin Russwin lock, or do I need a whole new cylinder?
The plug is the keyed core component only, a drop-in replacement inside a compatible CK4400, CK4455, or CK4482 cylinder body. You reuse the existing cylinder shell and housing. If your cylinder is a post-8/93 build, or a CK4429 Hotel function, the plug is the wrong route and you need a complete cylinder instead.
3) Can a Kaba Ilco 1539 universal key-in-lever cylinder be used instead of a Corbin Russwin 564K53 plug?
They solve different problems. The Corbin Russwin 564K53 27A1 is a replacement cylinder plug only, sold as a part for rebuilding CK4400 series (except CK4429 Hotel), CK4455 and CK4482 cylinders made before 8/93, in an A keyway. The Kaba Ilco 1539 is a complete key-in-knob/lever universal cylinder, so it replaces the whole cylinder rather than repinning the existing one. Choose the 564K53 when the original Corbin Russwin cylinder housing stays in the lock and only the plug is being swapped; choose a full cylinder such as the 1539 when the housing itself is being replaced.
4) What should I use for a Sargent key-in-lever instead of the Corbin Russwin 564K53?
The 564K53 27A1 plug is cut for the Corbin Russwin keying system with an A keyway and fits CK4400, CK4455 and CK4482 cylinders, so it will not serve a Sargent lock. The Kaba Ilco 1579 is a knob and lever cylinder made for Sargent. For Falcon RU/T series levers, the Falcon A23161-05 G is a 6-pin key-in-lever cylinder in the G keyway supplied keyed different with two cut keys.
5) For an aluminum storefront door, what cylinder should I look at instead of the Corbin Russwin 564K53 plug?
The 564K53 27A1 is an internal plug for Corbin Russwin CK4400, CK4455 and CK4482 cylinders and does not address storefront deadlock prep. For aluminum storefront work, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security rated for a 1/2 inch minimum door thickness, and the Adams Rite 4024 and 4025 are cylinder pulls for MS1847 deadlock and deadlatch systems, the 4025 being a five pin tumbler pull with through-screws. For wood door deadlocks, the Adams Rite 4026 five pin tumbler cylinder pull suits the 5017 wood door deadlock.
6) What is the 27, 57, 67, 77 option on the Corbin Russwin 564K53 order?
Those are the design numbers you specify alongside the finish and keyway, and all four (27, 57, 67, 77) are orderable. The full model designation on the common build reads 564K53 27A1, combining the 27 design with the A1 keyway.
7) My Corbin Russwin cylinder is newer than 1993 or a different brand entirely. What cylinder should I look at instead?
The 564K53 plug only serves pre-8/93 CK4400, CK4455, and CK4482 cylinders, so for anything outside that you want a complete replacement cylinder. For key-in-knob and key-in-lever housings there are universal options such as the Kaba Ilco 1539 and the 1599 key-in-knob replacement cylinder. For an interchangeable-core program, the BEST 1C 5-pin standard core or the Schlage 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam are the usual routes. Rim device applications take a rim cylinder like the Schlage 20-021 (vertical tailpiece cam) or 20-022 (horizontal cam).
8) Can I use a BEST interchangeable core instead of replacing the Corbin Russwin plug?
No, not in the same cylinder. The 564K53 is a pinned plug that goes inside an existing Corbin Russwin CK-series cylinder body; a BEST 1C core or 1CB Peaks 150 series core is a figure-eight interchangeable core that needs a BEST-prepped housing. Going to an IC system means changing the cylinder, not the plug.
9) If I want an interchangeable core system rather than repinning plugs, what is the alternative?
The Corbin Russwin 564K53 27A1 is a conventional 5 and 6-pin plug that a locksmith pins to the existing Corbin Russwin A keyway system, so rekeying means pulling the cylinder apart. Interchangeable core hardware changes that workflow: the BEST 1C5 is a standard 5-pin cylinder core, the BEST 1CB is a Peaks 150 series interchangeable core, and the BEST 1CDF is a drill resistant patented 7-pin brass 150 series core. Schlage's 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Those swap with a control key instead of a bench rebuild, but they require housings prepped for that core format.
10) Is a Schlage 20-021 rim cylinder a substitute for the Corbin Russwin 564K53?
No. The Schlage 20-021 is a complete 6-pin rim cylinder with a vertical tailpiece cam supplied with two keys, and the 20-022 is the same cylinder with a horizontal tailpiece cam; both mount behind a door as rim cylinders, typically for exit device trim. The Corbin Russwin 564K53 27A1 is a plug component that goes inside an existing Corbin Russwin CK4400, CK4455 or CK4482 cylinder. The two are not interchangeable parts of the same assembly.
11) What is the difference between the Corbin Russwin 564K53 plug and a Detex MC65 mortise cylinder?
The Detex MC65 is a complete 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, so it threads into a mortise lock body and keys to a Schlage C system. The Corbin Russwin 564K53 27A1 is a 5 and 6-pin X Class plug in an A keyway, keyed into the Corbin Russwin system and installed inside an existing CK4400, CK4455 or CK4482 cylinder. Pick by keyway system first: an A keyway facility stays with the Corbin Russwin plug.
12) Is there a Medeco equivalent to the Corbin Russwin 564K53 plug for high security?
Medeco's comparable parts are complete retrofit cylinders rather than plugs. The Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. None pin into a Corbin Russwin CK4400, CK4455 or CK4482 housing the way the 564K53 27A1 does, so moving to Medeco means changing the cylinder and the key system, not just the plug.
13) What finishes does the Corbin Russwin 564K53 cylinder plug come in?
Two: 606 satin brass and 626 satin chrome. Pick the one that matches the visible cylinder face on the rest of the openings, since the plug is the part you see in the keyhole.
14) Is the 564K53 rated for commercial door traffic or is it a residential part?
It's a commercial component, made for Corbin Russwin keying systems in offices, schools, hospitals, government buildings, retail, warehouses, and multi-tenant residential properties. It is not a consumer retrofit part.
15) I need a non-keyed filler for a door where nothing has to lock. Does the 564K53 work?
No. The Corbin Russwin 564K53 27A1 is a functional 5 and 6-pin plug that carries an A keyway and is meant to restore keyed operation in a CK4400, CK4455 or CK4482 cylinder. For an opening that only needs the look of a cylinder, the BEST 12E series dummy rim cylinder has a 1-5/32 inch diameter and no keyed function.
16) Is the Corbin Russwin 564K53 a commercial part, and what are the residential-leaning alternatives?
The 564K53 27A1 is classed as commercial door hardware and is offered in 606 satin brass and 626 satin chrome with A1 and A2 keyway options. Cylinders aimed at residential-style handleset and deadbolt hardware include the Emtek CY4 cylinder, sold each, and the Medeco 1065244, a 5-pin rim lazy motion rim type cylinder with an Emtek tailpiece. Those serve Emtek trim rather than Corbin Russwin CK series cylinders.
