Corbin Russwin 596K31 BL 626 – Frequently Asked Questions

1) Will the 596K31 plug work in a 6-pin cylinder, or only 5-pin?
Both. The 596K31 BL plug is built to accommodate 5-pin and 6-pin configurations across compatible CL3329 and CL3629 applications, so a hotel keyed to either pin count can use the same plug.
2) What does the BL keyway mean for keying a hotel property?
BL is the keyway profile this plug is cut for, and the plug has to match the keyway your property is already keyed to. The X Class designation is a restricted key control arrangement, so key duplication stays controlled. Ordering a plug in a different keyway than the rest of your master system means the existing keys will not enter it.
3) If I need a complete cylinder rather than just a plug, what should I order instead of the Corbin Russwin 596K31 BL?
The Corbin Russwin 596K31 BL is a 5 and 6-pin individual X Class cylinder plug for CL3329 and CL3629 Hotel cylinders - it is the keyed plug that goes into an existing cylinder housing, not a whole cylinder. When the job calls for a complete assembly, the Detex MC65 is a 6-pin mortise cylinder with a Schlage C keyway in a 1-1/8 inch length, and the Schlage Commercial 20-021 is a complete 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys.
4) I want an interchangeable core system so I can rekey without disassembling the cylinder - what are my options compared with the 596K31 BL?
Servicing the 596K31 BL means working at the plug level inside a CL3329 or CL3629 Hotel cylinder. For core-swap rekeying instead, the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam and 2 keys, the Schlage 20-057-C is an FSIC core in the C keyway with a 643E Aged Bronze finish, and the BEST 1CB is a 1CB 150 Series interchangeable core cylinder.
5) Does the 596K31 BL work on a deadbolt, and if not what does?
The 596K31 BL is a plug for CL3329 and CL3629 Hotel series cylinders, which are lockset cylinders rather than deadbolt cylinders. For deadbolt work, 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, and the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
6) I need a Grade 1 mortise cylinder for a narrow stile aluminum door - is the 596K31 BL the right part?
No. The 596K31 BL is a replacement X Class plug in the BL keyway for CL3329 and CL3629 Hotel cylinders, sold as a component rather than a rated cylinder assembly. For a narrow stile door, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder in the 4036 Series with a 1/2 inch minimum door thickness.
7) I need a replacement cylinder for a non-Corbin lock, not a Corbin hotel plug. What else is there?
The 596K31 BL only serves Corbin Russwin CL3329 and CL3629 hotel cylinders. For other platforms, look at the Kaba Ilco 1599 key-in-knob replacement cylinder, the Kaba Ilco 1579 knob and lever cylinder for Sargent, or the Falcon A23161-05 G key-in-lever cylinder in the 6-pin G keyway. For rim applications, the Schlage 20-021 (vertical tailpiece cam) and 20-022 (horizontal cam) are 6-pin rim cylinders.
8) Can I use an interchangeable core instead of rebuilding a plug like this?
Not in a CL3329 or CL3629 hotel cylinder, which takes this conventional X Class plug. Interchangeable core systems are a different platform entirely: the BEST 1C 5-pin standard core, the 1CB 150 Series core, or the Schlage 20-057 6-pin FSIC rim cylinder are examples. Those let you swap keying without disassembling a cylinder, but they require IC-prepped housings, so they are a system decision rather than a drop-in for this hotel plug.
9) Is a BEST 1C5 core an equivalent replacement for the Corbin Russwin 596K31 BL?
No. The BEST 1C5 is a standard 5-pin interchangeable core from the Standard and Premium Cores line, designed to drop into BEST interchangeable-core housings. The Corbin Russwin 596K31 BL is an individual X Class plug in the BL keyway built to fit inside CL3329 and CL3629 Hotel series cylinders, so the two serve different housings and different keying systems.
10) Is a cylinder pull like the Adams Rite 4025 a substitute for the 596K31 BL?
No. The Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws designed for use with the Adams Rite MS1847 deadlock/deadlatch, and the 4026 is a five pin tumbler cylinder pull for wood door applications with the 5017 wood door deadlock/deadlatch. Those are pull assemblies for specific Adams Rite deadlocks. The Corbin Russwin 596K31 BL is a 5 and 6-pin X Class plug that goes inside a CL3329 or CL3629 Hotel cylinder.
11) For a high security or drill resistant upgrade instead of replacing the 596K31 BL plug, what is available?
The 596K31 BL provides restricted key control through the BL keyway and X Class plug designation within CL3329 and CL3629 Hotel cylinders. If the specification calls for a drill resistant patented core instead, the BEST 1CDF is a drill resistant preferred patented interchangeable core, 7-pin brass, in the 150 Series.
12) What if the opening only needs a non-keyed filler and not the keyed 596K31 BL plug?
The 596K31 BL is a keyed X Class plug used where keying integrity must be maintained in CL3329 and CL3629 Hotel cylinders. Where no key function is needed, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills the prep without a working key mechanism.
13) Is this a residential part or commercial hotel hardware?
Commercial. The 596K31 BL plug is intended for commercial hotel locking applications, and typical use is hospitality cylinder replacement, property management rekeying programs, institutional and multi-tenant or extended-stay buildings.
14) Is the Corbin Russwin 596K31 a genuine factory part or an aftermarket copy?
Genuine Corbin Russwin. It is an authentic factory cylinder component, which matters on hotel cylinders because plug-to-shell tolerances and pin chamber spacing have to match the original for the cylinder to turn correctly and hold its keying.
15) Which finishes does the Corbin Russwin 596K31 BL plug come in, and how does that compare to other cylinder options?
The Corbin Russwin 596K31 BL X Class plug is offered in 606 Satin Brass and 626 Satin Chrome. Among comparable cylinders, the Schlage 20-057-C full size interchangeable core is listed in 643E Aged Bronze, so matching existing trim finish is worth confirming before substituting.
