Corbin Russwin 596K31 27A1 626 – Frequently Asked Questions

1) Will the Corbin Russwin 596K31 cylinder plug work in my CL3329 hotel lockset?
Yes. The 596K31 plug is built as the replacement cylinder plug for Corbin Russwin CL3329 and CL3629 Hotel series mechanical locks. It is an OEM Corbin Russwin part, so it drops into the host cylinder in those locksets without modifying the lock body. If your hotel lock is a different Corbin Russwin series, this is not the plug for it.
2) Does the 596K31 plug take 5-pin or 6-pin keying?
Both. The X Class plug accommodates 5-pin and 6-pin configurations, so it can be pinned to match whichever chamber count the rest of the property's Corbin Russwin system uses. That matters for a hotel or multi-family retrofit where you are pinning new plugs into an existing masterkey system rather than starting over.
3) What keyway options does the Corbin Russwin 596K31 cylinder plug come in?
It is an A keyway plug, orderable in A1 or A2. Pick the one that matches the key blanks and the existing keying system on the doors, since an A1 plug will not accept an A2 key and vice versa.
4) Do I have to replace the whole hotel lock, or can I just swap the cylinder plug?
Just the plug. The 596K31 27A1 is sold as a replacement component so you can restore cylinder function on a CL3329 or CL3629 Hotel lock without buying a complete lockset. For a property manager running a rekeying program across many guest rooms, that is the difference between a parts order and a hardware replacement project.
5) Can I use a Schlage or BEST cylinder instead of the Corbin Russwin 596K31?
No, not in a CL3329 or CL3629 hotel lock. The 596K31 is a plug for the Corbin Russwin cylinder in those locks, keyed to the A keyway. Products like the Schlage 20-021 and 20-022 are rim cylinders, and BEST's 1C 5-pin core and 1CB interchangeable core belong to BEST's own core systems. Those are separate cylinder formats and separate key systems, so they do not substitute here.
6) What exactly do I need to specify when ordering the 596K31 plug?
Four things: the model 596K31, the keyway (A1 or A2), the lever design (27, 57, 67 or 77) and the finish (606 satin brass or 626 satin chrome). Pin count is handled at keying, since the plug supports both 5 and 6 pins.
7) Can a BEST 1C interchangeable core be used in place of the Corbin Russwin 596K31 plug on a CL3329 hotel lock?
No. The Corbin Russwin 596K31 27A1 is a cylinder plug engineered specifically for CL3329 and CL3629 Hotel series locks with an A keyway, in 5-pin and 6-pin configurations. The BEST 1C5 is a standard 5-pin cylinder core from the Standard and Premium Cores line, and the BEST 1CB is a 150 Series interchangeable core cylinder - both are figure-eight interchangeable cores that require a BEST-style housing in the lock, not a Corbin Russwin hotel cylinder. To keep a CL3329 or CL3629 on its existing Corbin Russwin key system, the 596K31 plug is the part that matches.
8) What is the difference between the Corbin Russwin 596K31 cylinder plug and a complete mortise cylinder like the Detex MC65?
The 596K31 27A1 is a replacement cylinder plug - the keyed core component that restores cylinder function inside an existing CL3329 or CL3629 Hotel lock without replacing the full lock assembly, supplied with an A keyway in 5-pin and 6-pin form. The Detex MC65 is a complete mortise cylinder, 1-1/8 inch, 6-pin, cut to the Schlage C keyway. Order the MC65 when the opening needs a whole mortise cylinder body on a Schlage C system; order the 596K31 when the host Corbin Russwin hotel lock stays in the door and only the plug is being changed.
9) I need a cylinder for a rim exit device, not a hotel mortise lock - what should I order instead of the 596K31?
The 596K31 27A1 plug fits CL3329 and CL3629 Hotel series locks and will not serve a rim device. For rim applications, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, the 20-022 is the same rim cylinder with a horizontal tailpiece cam, and the 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Choose the cam orientation the exit device chassis calls for.
10) What finishes is the 596K31 X Class plug available in?
Two: 606 satin brass and 626 satin chrome. Match the plug face to the existing lever trim so the repaired door does not stand out from the rest of the corridor.
11) Which lever designs does the 596K31 plug cover?
Lever designs 27, 57, 67 and 77 are all covered, each in 606 satin brass or 626 satin chrome with an A1 or A2 keyway. Order the design code that matches the CL3329 or CL3629 lever already on the door.
12) What is an X Class plug and why does it matter for a hotel keying system?
X Class is Corbin Russwin's keying classification, and the plug is supplied as an individual X Class plug so it keeps the security segregation of the host system intact when you pin it. On hotel hardware that segregation is what separates guest keys from housekeeping, floor and master keys, so using a plug outside the class breaks the hierarchy you already have on the property.
13) If I want interchangeable cores so I can rekey without pinning plugs, what are my options?
The 596K31 is a conventional individual plug, pinned by a locksmith rather than swapped by hand. If your goal is to pull and replace cores in seconds, look at a full-size or small-format interchangeable core system instead: the BEST 1CB 150 Series interchangeable core, the BEST 1CDF drill-resistant patented 7-pin core, or Schlage's 20-057 6-pin FSIC rim cylinder and 20-057-C FSIC core. Those are different key systems, so they are a standardization decision for the building, not a like-for-like swap on a hotel lock.
14) Is the Kaba Ilco 1539 or 1599 universal cylinder an alternative to the Corbin Russwin 596K31?
They address different openings. The Kaba Ilco 1539 is a key-in-knob and lever universal cylinder and the 1599 is a key-in-knob replacement cylinder, both listed for deadbolt function. The Corbin Russwin 596K31 27A1 is an X Class cylinder plug for CL3329 and CL3629 Hotel mortise locks with an A keyway, and it keeps the X Class keying system on those locks intact. If the hardware in the door is a Corbin Russwin hotel lock, the 596K31 is the matching part; the Ilco cylinders serve key-in-knob and lever or deadbolt retrofits.
15) We standardize on Sargent and Falcon key systems in other buildings - what cylinders match those instead of the 596K31 A keyway?
The 596K31 27A1 is offered in A1 and A2 keyways for Corbin Russwin CL3329 and CL3629 Hotel locks, so it stays on a Corbin Russwin key system. For a Sargent system, the Kaba Ilco 1579 is a knob and lever cylinder made for Sargent. For a Falcon system, the A23161-05 G is a key-in-lever cylinder, RU/T Series, 6-pin G keyway, keyed different with two cut keys. Each of those follows its own keyway family and will not key into an A keyway master system.
16) What looks like a substitute for the 596K31 cylinder plug but is not?
Cylinder pulls and dummy cylinders are the usual mix-ups. The Adams Rite 4024 is a cylinder pull with trim plate mounting and the 4025 a five pin tumbler cylinder pull with through-screws, both for the MS1847 deadlock, while the 4026 is a five pin cylinder pull for the 5017 wood door deadlock - those are pull hardware for narrow stile and wood door deadlocks. The BEST 12E is a dummy rim cylinder with a 1-5/32 inch diameter, which provides no keyed function at all. The Corbin Russwin 596K31 27A1 is a keyed X Class plug that restores cylinder operation in CL3329 and CL3629 Hotel locks.
17) For a high-security or drill resistant upgrade rather than a like-for-like hotel lock plug, what are the options?
The Corbin Russwin 596K31 27A1 is a genuine OEM plug that keeps CL3329 and CL3629 Hotel locks on their original X Class keying, in 5-pin or 6-pin form. If the goal is a higher attack-resistance specification on the opening, the BEST 1CDF is a drill resistant preferred patented interchangeable core, 7-pin brass, 150 Series, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder from the 4036 Series with a 1/2 inch minimum door thickness. Those change the cylinder platform and the key system, so plan the keying accordingly.
18) Will a Medeco retrofit cylinder work in a Corbin Russwin CL3629 hotel lock instead of the 596K31?
No. The Medeco retrofit cylinders are built for other host hardware: the 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, 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. For a CL3629 Hotel lock, the 596K31 27A1 X Class plug with an A keyway is the manufacturer-specified fit.
19) Our hotel is moving to full size interchangeable core so housekeeping cores can be swapped without a locksmith - is the 596K31 the right direction?
The 596K31 27A1 is a fixed X Class plug that is keyed as part of the Corbin Russwin hotel lock cylinder and is intended to restore the existing system on CL3329 and CL3629 locks. If the program calls for cores that pull and replace in the field, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and the 20-057-C is a full size interchangeable core in the C keyway, finish 643E Aged Bronze. Those require FSIC-prepped housings, so the change is a hardware decision, not just a keying one.
20) Is the 596K31 a residential part or is it rated for commercial use?
Commercial. It is a commercial door hardware component, used in hospitality, offices, multi-tenant residential, healthcare, education and government buildings. It is not a residential-grade cylinder.
21) Does the 596K31 finish choice matter when matching other cylinders on the job?
The Corbin Russwin 596K31 27A1 plug is offered in 606 Satin Brass and 626 Satin Chrome across the A1 and A2 keyways, so it can be matched to the visible trim on hotel openings. Comparable cylinders carry their own finish designations - the Schlage 20-057-C, for example, is listed in 643E Aged Bronze - so a mixed-brand set of cylinders on one elevation will not necessarily read as the same finish.
