Corbin Russwin 596K31 AR 626 – Frequently Asked Questions

1) Which Corbin Russwin locks does the 596K31 AR cylinder plug fit?
The 596K31 AR plug is built for Corbin Russwin CL3329 and CL3629 Hotel lock cylinders. It drops into those cylinder bodies as an OEM part with no modification. It is not a complete cylinder, so if the whole cylinder body is damaged or worn you need the cylinder assembly rather than the plug alone.
2) Will the 596K31 plug work with my existing Corbin Russwin master key system?
Only if your system runs the AR keyway. This plug is cut for the AR keyway, and a plug in the wrong keyway will not accept your existing keys no matter how it is pinned. It takes both 5-pin and 6-pin Individual X Class configurations, so it can be pinned into a hotel keying hierarchy with guest, master and grand master levels.
3) Is a Schlage 20-057 FSIC core an alternative to the Corbin Russwin 596K31 AR plug?
No. The Corbin Russwin 596K31 AR is a 5 and 6-pin Individual X Class cylinder plug made to go into existing Corbin Russwin CL3329 and CL3629 hotel cylinders on the AR keyway, so the cylinder housing stays in the door and only the plug is replaced. 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, 643E Aged Bronze. Those are Schlage-keyed cores and rim cylinders, not Corbin Russwin plugs, so they will not key into or fit a CL3329 or CL3629 hotel cylinder.
4) Do I need a locksmith to install a 596K31 hotel cylinder plug?
Practically, yes. Swapping a plug means pulling the cylinder, shearing the pin stack, loading the correct bottom pins and masters for your X Class chart, and reassembling to the existing key bitting. There are no keys or pins supplied with the plug itself, so whoever installs it needs the keying records and a pin kit.
5) Can I use a BEST interchangeable core instead of replacing the Corbin Russwin plug?
Not in a CL3329 or CL3629 hotel cylinder. BEST cores such as the 1C5 5-pin core or the 1CB 150 Series interchangeable core need a figure-eight core housing, which is a different cylinder format entirely. Converting an opening to interchangeable core means changing the cylinder, not the plug. If you want IC as a standard going forward, the BEST 1CDF drill resistant 7-pin core is a patented option worth pricing against a plug-level repair.
6) Should I order 5-pin or 6-pin for the 596K31 AR plug?
The plug itself covers both. It accepts 5-pin and 6-pin Individual X Class configurations, so the decision is made by your existing keying chart, not by ordering a different plug. Pin it to match whatever depth the rest of the property runs so one master still passes.
7) How does the 596K31 AR plug differ from a BEST interchangeable core?
The Corbin Russwin 596K31 AR is a 5 and 6-pin Individual X Class plug pinned for the AR keyway and used inside Corbin Russwin CL3329 and CL3629 hotel cylinders; servicing it means working the plug into the cylinder. BEST offers interchangeable cores instead: the 1C5 is a standard 5-pin cylinder core, the 1CB is a Peaks 150 Series interchangeable core, and the 1CDF is a drill-resistant patented 7-pin brass 150 Series core. Interchangeable cores pull and swap with a control key in BEST-prepped housings, which is a different service approach and a different key system from Corbin Russwin AR.
8) Will a Kaba Ilco universal cylinder work in place of the Corbin Russwin 596K31 AR?
They serve different openings. The 596K31 AR is a plug for Corbin Russwin CL3329 and CL3629 hotel mortise cylinders. The Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the 1549 Series is a key-in-deadbolt cylinder, and the 1579 Series is a knob and lever cylinder for Sargent. Those replace knob, lever, or deadbolt cylinders rather than seating a plug in a Corbin Russwin hotel cylinder, and none of them are cut for the AR keyway.
9) I need a keyed cylinder for an aluminum storefront deadlock, not a hotel lock plug. What fits that?
The Corbin Russwin 596K31 AR is a hotel cylinder plug for CL3329 and CL3629 cylinders and is not a storefront part. For Adams Rite deadlock service, the 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch 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 Adams Rite 5017 wood door deadlock and deadlatch. Choose by the deadlock model already in the door.
10) For a residential handleset or deadbolt retrofit, is the 596K31 AR the right cylinder?
No. The 596K31 AR is a commercial Corbin Russwin hotel cylinder plug on the AR keyway. For handleset and deadbolt retrofits the Medeco options apply instead: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, 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.
11) What is the difference between the 596K31 AR plug and a rim cylinder like the Schlage 20-021 or 20-022?
The 596K31 AR is a cylinder plug that goes inside an existing Corbin Russwin CL3329 or CL3629 hotel cylinder on the AR keyway, in 606 Satin Brass or 626 Satin Chrome. The Schlage 20-021 and 20-022 are complete 6-pin rim cylinders supplied with two keys, the 20-021 with a vertical tailpiece cam and the 20-022 with a horizontal tailpiece cam; rim cylinders mount through the door to drive exit device or rim lock hardware. The cam orientation is what separates the two Schlage numbers from each other.
12) Is the 596K31 AR rated for commercial hotel use or is it a residential part?
Commercial. It is an OEM Corbin Russwin mechanical lock component intended for hotel and hospitality, healthcare, education, government and multi-tenant residential openings, not a consumer-grade replacement.
13) Can I use a dummy cylinder instead of the 596K31 AR plug on a door that does not need to be keyed?
If an opening needs the look of a cylinder without key function, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter covers that role. The Corbin Russwin 596K31 AR is the opposite case: it is a working 5 and 6-pin Individual X Class plug that carries the AR keyway and supports master keying hierarchies, so it belongs on doors that must stay in the hotel key system.
14) I need a lever lock cylinder on a different key system than Corbin Russwin AR. What is the equivalent part?
The Corbin Russwin 596K31 AR plug is tied to the AR keyway and to CL3329 and CL3629 hotel cylinders, so it cannot be used on another manufacturer's key system. For a lever application on a Falcon system, the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series 6-pin G keyway, keyed different, supplied with two cut keys. Emtek's CY4 cylinder is sold individually as a parts item for Emtek hardware.
