Corbin Russwin 596K31 27 626 – Frequently Asked Questions

1) Does the 596K31 plug take 5-pin or 6-pin keying?
Both. The 596K31 supports 5-pin and 6-pin configurations, so it can be pinned to match whichever depth your existing Corbin Russwin hotel key system uses. That matters when you are standardizing guest room doors across a property that was originally pinned one way and expanded later.
2) Which keyways can I order the Corbin Russwin 596K31 plug in?
Five X Class keyway choices: 27, 67, 77, 97 and 99. Pick the one that matches the keyway already in your master key system, since a plug in the wrong keyway will not accept your existing guest and master keys.
3) I need a full mortise cylinder, not just a plug - what should I order instead?
The Corbin Russwin 596K31 27 is supplied as an individual cylinder plug for targeted replacement inside CL3329 and CL3629 Hotel series locks, not as a complete cylinder body. If the whole cylinder is being replaced, a full mortise cylinder is the right item: the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder in the 4036 series, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway. Both are separate cylinders rather than components that drop into an existing Corbin Russwin housing.
4) Is there a cross-brand equivalent to the Corbin Russwin 596K31 27 cylinder plug?
No. The 596K31 27 is a genuine Corbin Russwin cylinder plug built to the X Class keyway specification for CL3329 and CL3629 Hotel series mortise locks, so the key control and plug geometry are specific to Corbin Russwin systems. Other-brand cylinders are keyed and built to their own systems: the Detex MC65 mortise cylinder uses a Schlage C keyway in a 1-1/8 inch 6-pin body, the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T 6-pin G keyway, and the Kaba Ilco 1579 knob and lever cylinder is made for Sargent. If the door has a Corbin Russwin X Class system, the plug is the part that keeps that system intact.
5) What finishes does the 596K31 hotel lock cylinder plug come in?
Two: 606 Satin Brass and 626 Satin Chrome, and both are available across all five keyways (27, 67, 77, 97, 99). Match the plug finish to the existing lock trim so a single replaced guest room door does not stand out on the floor.
6) I need a rim cylinder for an exit device, is this the right part?
No. The 596K31 is a mortise lock cylinder plug for Corbin Russwin hotel locks and has no rim cam or tailpiece. For an exit device you need a rim cylinder, for example the Schlage 20-021 6-pin with vertical tailpiece cam or the 20-022 with horizontal tailpiece cam.
7) Do the 596K31 plugs come pinned and keyed, or do I need a locksmith?
Order it by keyway (27, 67, 77, 97 or 99) and finish; the pinning to your 5-pin or 6-pin key system is keying work, so plan on a locksmith or in-house shop with the right pin kit and your key bitting. Buying the keyway that matches your existing X Class system is what lets them pin it into your master key hierarchy.
8) Will a rim cylinder work in place of the Corbin Russwin 596K31 27?
No - rim cylinders mount through the door and drive an exit device or rim lock with a tailpiece, while the 596K31 27 is a plug that goes into an existing CL3329 or CL3629 Hotel series mortise lock cylinder. If the opening actually needs a rim cylinder, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam, each supplied with two keys. Those are rim-function parts and will not seat in a mortise cylinder housing.
9) Can I use an interchangeable core instead of the 596K31 plug for easier rekeying?
Not in a CL3329 or CL3629 Hotel lock - the 596K31 27 is a fixed X Class plug that pins to the Corbin Russwin key system and supports 5-pin and 6-pin configurations. Interchangeable-core hardware is a different platform: the BEST 1C 5-pin standard core and the BEST 1CB 150 series interchangeable core are made to pull and swap from an IC housing, and the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Those require IC-prepped hardware rather than a Corbin Russwin plug replacement.
10) What do I order for a deadbolt or key-in-knob rekey instead of the 596K31 27 plug?
The 596K31 27 plug is for Corbin Russwin CL3329 and CL3629 Hotel series mortise locks. For deadbolt and knob or lever applications, the Kaba Ilco line covers those functions: the 1539 is a key-in-knob/lever universal cylinder, the 1549 is a key-in-deadbolt cylinder, and the 1599 is a key-in-knob replacement cylinder. Each is a separate cylinder assembly rather than a plug component for a hotel mortise lock.
11) What is the difference between the 596K31 27 and a retrofit cylinder like the Medeco 1065140?
The Corbin Russwin 596K31 27 is an OEM plug that keeps an existing Corbin Russwin CL3329 or CL3629 Hotel lock on its own X Class key system, offered in 606 satin brass and 626 satin chrome. The Medeco retrofit cylinders are aftermarket cylinders built to adapt other manufacturers' locks: the 1065140 is a 5-pin retrofit cylinder 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, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Those change the lock over to a Medeco key system rather than preserving the original one.
12) Is the 596K31 plug suitable for anything other than hotels?
It is a commercial-grade part, and the same Corbin Russwin hotel-function hardware shows up well beyond lodging: office buildings, healthcare, schools, government facilities and multi-tenant residential where key-controlled access is in place. The limit is the lock, not the building type, it has to be a CL3329 or CL3629.
13) Is a cylinder pull like the Adams Rite 4024 or 4025 a substitute for this Corbin Russwin plug?
No. The Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock systems, the 4025 is a five-pin tumbler cylinder pull with through-screws for the MS1847, and the 4026 is a five-pin tumbler cylinder pull for the 5017 wood door deadlock - all are door pull assemblies that carry a cylinder, typically on narrow stile or storefront hardware. The Corbin Russwin 596K31 27 is an internal X Class plug for a CL3329 or CL3629 Hotel series mortise lock and has no pull or trim function.
14) I need a non-keyed filler for an unused cylinder hole - does the 596K31 27 do that?
No. The 596K31 27 is a keyed X Class plug that carries the pinning for a Corbin Russwin CL3329 or CL3629 Hotel lock. For an opening where no key function is wanted, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter fills a rim cylinder prep without operating hardware.
