Corbin Russwin 596K31 57D1 626 – Frequently Asked Questions

1) Does the 596K31 work in both 5-pin and 6-pin cylinders?
Yes. The 596K31 plug accommodates 5-pin and 6-pin configurations, so the same part covers both pinning depths used in the CL3329 and CL3629 hotel cylinder family. That matters if a property has a mix of 5-pin and 6-pin masterkeying across floors, since you are not stocking two plugs.
2) What keyway do I have to specify when ordering the Corbin Russwin 596K31 plug?
Keyway is an order choice on the 596K31, offered as D1 or D2 within the 57D keyway family. Pick the one that matches the key blanks and master key system already in use in the building, because the plug is machined for that keyway and a mismatch will not accept your existing keys.
3) I need a complete cylinder, not just a plug. What should I be looking at instead?
The 596K31 is only the plug, the keyed core barrel of the cylinder, so it will not help if you have no serviceable cylinder body. For a complete unit you would order a full mortise or rim cylinder. Comparable complete cylinders we carry include the Detex MC65 mortise cylinder in a Schlage C keyway 6-pin, the Adams Rite 4036 Grade 1 mortise cylinder, and Schlage's 20-021 and 20-022 rim cylinders with vertical and horizontal tailpiece cams. None of those will carry a Corbin Russwin 57D key, so if you must stay on the existing hotel key system, the plug route is the one that preserves it.
4) If I want to rekey hotel doors without disassembling cylinders, what should I use instead of a 596K31 plug?
Servicing a 596K31 57D1 plug means pulling the Corbin Russwin CL3329 or CL3629 cylinder and swapping the plug at the bench. If the goal is field rekeying by hand, an interchangeable core platform is the different approach: the BEST 1CB is a 150 series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented 7-pin interchangeable core in the 150 series, and the Schlage 20-057-C is a full size interchangeable core in the C keyway. Those cores come out with a control key, but they are separate keying systems and will not run on 57D keys.
5) Can I rekey a hotel lock with just the plug instead of buying a whole new cylinder?
That is the point of the 596K31. It is a genuine Corbin Russwin replacement plug meant to restore or reconfigure an existing cylinder assembly, so a locksmith can repin to a revised master key system or replace a worn or damaged plug without pulling a full cylinder or lock. Useful for master key system reconfiguration and routine hotel lock servicing.
6) If I want interchangeable cores so housekeeping changes can be done without a locksmith, is this the right part?
No. The 596K31 is a conventional plug that has to be pinned and installed into the cylinder, not a swappable core. For a keying system where cores are pulled and replaced with a control key, look at interchangeable core products instead, such as the BEST 1CB 150 Series core, the BEST 1CDF 7-pin drill resistant core, or Schlage's 20-057 full size interchangeable core rim cylinder. Moving to interchangeable core means changing the cylinder, not just the plug.
7) What is the exact model designation for this Corbin Russwin plug so I order the right one?
The model is 596K31 57D1, the 596K31 X Class plug in the 57D keyway. When you order, confirm the keyway suffix (D1 or D2) and the finish, 606 satin brass or 626 satin chrome, since those are the variables on the part.
8) Will a Schlage rim cylinder work as a substitute for the Corbin Russwin 596K31?
No. The Schlage 20-021 and 20-022 are 6-pin rim cylinders, differing from each other in tailpiece cam orientation - vertical on the 20-021 and horizontal on the 20-022 - and they mount through a door to drive a rim exit device or rim lock. The 596K31 57D1 is a plug that seats inside an existing Corbin Russwin CL3329 or CL3629 Hotel mortise cylinder in the 57D keyway. Different part of the assembly entirely, so neither rim cylinder fits the mortise application.
9) What is the equivalent of the 596K31 plug for a knob or lever lock from another manufacturer?
The 596K31 57D1 serves Corbin Russwin CL3329 and CL3629 Hotel mortise cylinders. For key-in-knob and key-in-lever replacements on other lines, the Kaba Ilco 1539 is a key-in-knob/lever universal cylinder, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, the Kaba Ilco 1599 is a key-in-knob replacement cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T series 6-pin G keyway supplied keyed different with two cut keys. Those are complete cylinders for knob and lever hardware rather than plugs for a hotel mortise cylinder.
10) I need a keyed cylinder for a deadbolt, not a hotel mortise lock - what takes the place of the 596K31?
The 596K31 57D1 is built for Corbin Russwin CL3329 and CL3629 Hotel mortise cylinders, so it has no deadbolt application. For deadbolts, the Kaba Ilco 1549 is a key-in-deadbolt cylinder, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the Medeco 1065244 is a 5-pin lazy motion rim cylinder supplied with an Emtek tailpiece.
11) How does the 596K31 plug differ from a BEST 1C5 core?
Both are the keyed element that carries the pinning rather than a complete cylinder, but they belong to different systems. The BEST 1C5 is a standard 5-pin cylinder core from the standard and premium cores line and is removed with a control key from BEST housings. The Corbin Russwin 596K31 57D1 is an X Class plug machined for the 57D keyway, supports 5-pin and 6-pin configurations, and is fitted into Corbin Russwin CL3329 and CL3629 Hotel mortise cylinders. They are not interchangeable in either direction.
12) Does the 596K31 57D1 plug retrofit an Emtek or Arrow lock?
No. It is machined for the 57D keyway and fits Corbin Russwin CL3329 and CL3629 Hotel mortise cylinders only. For those other lines the retrofit parts are separate items: the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and for the Emtek handleset and deadbolt outside cylinder, and the Emtek CY4 is a cylinder sold each for Emtek hardware.
13) Is the 596K31 plug rated for commercial hotel use or is it a residential part?
Commercial. The 596K31 is classed as a commercial part and built to the standards of the Corbin Russwin 596K cylinder parts line, aimed at hotel and hospitality service work along with institutional, healthcare, education and multi-unit property lock maintenance.
14) Can a cylinder pull be used where a 596K31 plug is specified?
No. The Adams Rite 4024 is a cylinder pull with trim plate mounting and the 4025 is a five pin tumbler cylinder pull with through-screws, both for the Adams Rite MS1847 deadlock/deadlatch, while the 4026 is a five pin tumbler cylinder pull for the Adams Rite 5017 wood door deadlock/deadlatch. Those are pull handles with an integral cylinder for narrow stile and wood door deadlocks. The 596K31 57D1 is an internal replacement plug for a Corbin Russwin CL3329 or CL3629 Hotel mortise cylinder and does not serve as door trim.
15) I only need to fill a cylinder hole with no key function - is the 596K31 the right part?
No. The 596K31 57D1 is a keyed X Class plug that restores key operation in a Corbin Russwin CL3329 or CL3629 Hotel mortise cylinder. For a non-keyed opening, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is the blank-off option, with no keying and no cam action.
