Corbin Russwin 596K31 57C1 626 – Frequently Asked Questions

1) Will a 596K31 plug work in my existing Corbin Russwin keying system?
Only if your system uses the 57C keyway. The 596K31 is made exclusively for 57C, and it is an Individual X Class plug, so it sits inside Corbin Russwin's X Class key control hierarchy. If your hotel doors are keyed on a different Corbin Russwin keyway, this plug will not accept your keys.
2) What is the difference between the C1 and C2 keyway options on the 596K31?
C1 and C2 are the two keyway choices offered on the 596K31 within the 57C family. Which one you order has to match the keyway already cut into the rest of your hotel cylinders, because a key cut for one will not enter the other. Pick the code that matches the doors you are servicing.
3) Can a BEST 1C core replace a Corbin Russwin 596K31 plug in a CL3329 hotel lock?
No. The Corbin Russwin 596K31 is a cylinder plug built for Corbin Russwin CL3329 and CL3629 hotel mortise lock cylinders in the 57C keyway, so it goes inside an existing Corbin Russwin cylinder housing. The BEST 1C5 is a standard 5-pin interchangeable cylinder core from BEST's Standard and Premium Cores line, which drops into BEST-style small format interchangeable core housings instead. The two are different key systems and different housings, so one does not serve as the other.
4) If I need a complete mortise cylinder rather than just a plug, what should I look at?
The Corbin Russwin 596K31 is a replacement plug only - the 5 and 6-pin X Class plug that carries the pins inside a CL3329 or CL3629 hotel lock cylinder. If the whole cylinder body is damaged or missing, a complete mortise cylinder is the right buy: the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder. Both are separate key systems from the Corbin Russwin 57C keyway, so keying has to be planned accordingly.
5) My opening is a rim exit device, not a hotel mortise lock - what cylinder do I use instead of the 596K31?
The 596K31 plug is specific to Corbin Russwin CL3329 and CL3629 hotel mortise lock cylinders and will not serve a rim device. For rim applications, look at the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam or the 20-022 with a horizontal tailpiece cam, matching the cam orientation your device requires. The BEST 12E dummy rim cylinder, with a 1-5/32 inch diameter, fills a rim prep where no key function is needed.
6) I have an Adams Rite MS1847 narrow stile deadlock - can I order the 596K31 for it?
No. The 596K31 plug is matched to Corbin Russwin CL3329 and CL3629 hotel mortise lock cylinders. For an MS1847, the Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both designed for use with the Adams Rite MS1847 deadlock/deadlatch. For a wood door, the 4026 five pin tumbler cylinder pull is designed for the Adams Rite 5017 wood door deadlock/deadlatch.
7) Does this Corbin Russwin plug come in 5-pin or 6-pin?
Both. The 596K31 supports 5-pin and 6-pin configurations, so it can be pinned to suit a straightforward guest-room key or a deeper master keying system with an extra pin chamber.
8) What finishes is the 596K31 hotel lock cylinder plug available in?
Two: 606 satin brass and 626 satin chrome. The plug face is the visible part once the key is out, so match it to the existing cylinder collar and lever trim on the guest room doors rather than choosing at random. Both finishes are offered in the C1 and C2 keyways.
9) Can I use a BEST interchangeable core in a Corbin Russwin CL3329 hotel lock instead of this plug?
No. BEST cores such as the 1C 5-pin standard core or the 1CB Peaks 150 Series interchangeable core are a different cylinder platform and do not drop into a Corbin Russwin CL3329 or CL3629 cylinder. Converting a door to a BEST core means replacing the cylinder housing, not just the plug, and it takes that door out of your 57C key system.
10) What is the difference between the Corbin Russwin 596K31 plug and a Schlage 20-057 FSIC core?
The 596K31 is an Individual X Class plug for the 57C keyway, keyed and pinned to fit Corbin Russwin CL3329 and CL3629 hotel lock cylinders, and it is offered in 606 satin brass and 626 satin chrome. The Schlage 20-057 is a 6-pin full size interchangeable core with a convertible tailpiece cam, and the 20-057-C is an FSIC core in the Schlage C keyway. FSIC cores are pulled and swapped with a control key in Schlage-prepped housings; the Corbin Russwin plug is serviced inside its own cylinder.
11) Is a Kaba Ilco replacement cylinder a substitute for the Corbin Russwin 596K31?
They solve different problems. The Kaba Ilco 1539 is a key-in-knob and lever universal cylinder and the 1579 is a knob and lever cylinder made for Sargent locks - both are complete aftermarket cylinders for knob and lever bodies. The Corbin Russwin 596K31 is the plug component for CL3329 and CL3629 hotel mortise lock cylinders in the 57C keyway, so it is what you order to keep an existing Corbin Russwin hotel cylinder in its original key system.
12) Which cylinder options offer high-security or drill resistance compared with the Corbin Russwin 596K31?
The 596K31 is a genuine Corbin Russwin Individual X Class plug for the 57C keyway, supporting 5-pin and 6-pin configurations for master keying within the Corbin Russwin key control hierarchy. If drill resistance and patented key control are the requirement, the BEST 1CDF is a drill resistant, preferred patented interchangeable core in 7-pin brass from the 150 series, and the BEST Peaks 1CB is a 150 series interchangeable core cylinder. Those are BEST small format core systems, so switching means moving that opening off the Corbin Russwin keyway.
13) For a residential-style handleset or deadbolt, is the Corbin Russwin 596K31 the right cylinder part?
No. The 596K31 is a commercial replacement plug for Corbin Russwin CL3329 and CL3629 hotel mortise lock cylinders. For handlesets and deadbolts, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts. Emtek's own CY4 cylinder is sold as a single part as well.
14) Will a Falcon key-in-lever cylinder work in place of the Corbin Russwin 596K31?
No. The Falcon A23161-05 G is a key-in-lever cylinder for the RU/T series in a 6-pin G keyway, supplied keyed different with two cut keys, and it fits Falcon lever bodies. The Corbin Russwin 596K31 is the X Class plug for CL3329 and CL3629 hotel mortise lock cylinders on the 57C keyway, available in C1 and C2 keyway variations with 606 satin brass or 626 satin chrome plugs.
15) Is the 596K31 a genuine Corbin Russwin part or an aftermarket copy?
It is a genuine Corbin Russwin cylinder component, made to OEM tolerances so it drops into CL3329 and CL3629 cylinders without fitting work. For a property running a factory Corbin Russwin key system, using the OEM plug keeps the key control records and pinning charts valid.
16) Is this plug suitable for anything other than hotels?
It is a commercial-duty part, and it turns up anywhere Corbin Russwin CL3329 or CL3629 locks are installed: office entries, multi-tenant and mixed-use buildings, healthcare, schools, and municipal buildings running scheduled rekeying programs. The deciding factor is the lock and keyway, not the building type.
