Corbin Russwin 606K76 57A2 626 – Frequently Asked Questions

1) Will the 606K76 plug work in my Corbin Russwin mortise cylinder if my system uses a different keyway?
No. This plug is cut for the 57A2 keyway, so it only accepts keys in that keyway family. Pinning it into a system on another Corbin Russwin section will not let your existing keys enter. Order the plug in the keyway your master key system is built on.
2) Can a 7-pin plug be used in a 6-pin Corbin Russwin cylinder housing?
No. The 606K76 is a 7-pin plug and has to go into a 7-pin shell with matching chamber spacing and length. A 6-pin housing will not take it. Count the chambers in the shell you are servicing before you order.
3) Can I use this plug in a rim cylinder or a key-in-knob cylinder?
No. The 606K76 plug is built for 2-1/4 inch mortise cylinders only. For a rim application, look at a rim cylinder such as the Schlage 20-021 with vertical tailpiece cam or the 20-022 with horizontal cam. For key-in-knob or lever replacement, a Kaba Ilco 1599 key-in-knob cylinder is the right family.
4) If I need a complete mortise cylinder rather than just a plug, what should I order instead of the Corbin Russwin 606K76?
The 606K76 is a cylinder plug only - a replacement component for 2-1/4 inch Corbin Russwin mortise cylinders with the 57A2 keyway. If the opening needs a whole cylinder body, the Detex MC65 is a mortise cylinder in 1-1/8 inch length with a Schlage C keyway and 6-pin configuration, and the Adams Rite 4036 is a five-pin mortise cylinder in the 4036 Series rated Grade 1 with a 1/2 inch minimum door thickness. Both are complete cylinders rather than plugs, and neither uses the Corbin Russwin 57A2 keyway, so they will not key into an existing 57A2 system.
5) We want to move away from fixed cylinders to an interchangeable core system - what is the alternative to a 606K76 plug?
The 606K76 is a fixed-cylinder plug that is pinned into a Corbin Russwin mortise cylinder, so rekeying means pulling and repinning the plug. For a core-swap system instead, the BEST 1C Series is a standard 5-pin interchangeable core, the BEST 1CB is a Peaks 150 Series interchangeable core, and the BEST 1CDF is a drill-resistant patented 7-pin brass core in the 150 Series. On the Schlage side, the 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam, and the 20-057-C is an FSIC core in C keyway, 643E aged bronze. Moving to any of these changes the cylinder housing as well as the key system.
6) The lock on our door is a key-in-lever, not a mortise lock - what cylinder do I need instead of the 606K76?
The 606K76 plug fits 2-1/4 inch Corbin Russwin mortise cylinders and will not go into a key-in-lever or key-in-knob chassis. For those, the Falcon A23161-05 G is a key-in-lever cylinder for the RU/T series with a 6-pin G keyway, keyed different with two cut keys. The Kaba Ilco 1539 Series is a universal key-in-knob and lever cylinder, the 1599 is a key-in-knob replacement cylinder, and the 1579 is a knob and lever cylinder made for Sargent locks. Match the cylinder to the lock chassis brand before ordering.
7) Is the 606K76 the right part for an aluminum storefront door with an Adams Rite deadlock?
It is not a match for that hardware. The 606K76 is a 7-pin X Class plug built for 2-1/4 inch Corbin Russwin mortise cylinders. Aluminum storefront openings running an Adams Rite MS1847 deadlock or deadlatch take the Adams Rite 4024 cylinder pull, which mounts with a trim plate, or the 4025 five pin tumbler cylinder pull, which uses through-screws. For a wood door running the Adams Rite 5017 deadlock or deadlatch, the 4026 is the five pin tumbler cylinder pull built for that application.
8) I manage a building keyed on Corbin Russwin X Class. Can I rekey doors by swapping this plug?
That is exactly what this part is for. Swapping the plug in a 2-1/4 inch mortise cylinder gives you a fresh keying without pulling the lock body or buying a whole new cylinder, and it keeps the opening inside your existing X Class 57A2 key system. Useful for tenant turnover or a compromised key in commercial offices, schools, healthcare, and multi-tenant residential.
9) What is the difference between an X Class plug like this and an interchangeable core such as the BEST 1CDF?
Different servicing models. The Corbin Russwin 606K76 is a plug that a locksmith pins and installs inside a fixed mortise cylinder shell, so rekeying means taking the cylinder apart. An interchangeable core like the BEST 1CDF 7-pin core pulls out with a control key and is swapped whole, no disassembly. If you want field-swappable cores across a facility, the IC route fits better; if your doors already carry conventional Corbin Russwin mortise cylinders, the plug is the direct service part.
10) Will a Schlage 20-021 or 20-022 rim cylinder work in place of the Corbin Russwin 606K76?
No. The 606K76 is a plug for a 2-1/4 inch mortise cylinder. The Schlage 20-021 and 20-022 are rim cylinders, differing from each other only in tailpiece cam - vertical on the 20-021 and horizontal on the 20-022 - and both ship 6-pin with two keys. Rim cylinders mount through the door and drive a rim exit device or rim deadlatch; they do not thread into a mortise lock body. Confirm whether the device on the door takes a mortise or a rim cylinder before ordering either.
11) What is the difference between ordering a 606K76 plug and ordering a dummy cylinder like the BEST 12E?
The 606K76 is a working 7-pin plug with the 57A2 keyway, meaning it accepts a key and carries the pinning for a keyed system. The BEST 12E Series is a dummy rim cylinder with a 1-5/32 inch diameter - it fills the cylinder opening and provides the correct appearance and trim without any keyed function. Use the 606K76 where the opening must be keyed and the 12E where the hole needs to be closed off on a non-keyed leaf.
12) Can I use a Kaba Ilco 1549 deadbolt cylinder as a substitute for the Corbin Russwin 606K76?
No. The Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, functionally a deadbolt cylinder, and the 1539 and 1599 Series are likewise deadbolt-function cylinders for knob and lever hardware. The 606K76 is a plug that drops into an existing Corbin Russwin 2-1/4 inch mortise cylinder body and carries the 57A2 keyway, so it is the only one of the group that will key into an existing 57A2 Corbin Russwin master key system.
13) For a high-security retrofit, what are my options next to the Corbin Russwin 606K76 7-pin plug?
The 606K76 is a 7-pin Individual X Class plug, and the X Class 57A2 keyway is proprietary to Corbin Russwin for controlled key duplication. If the goal is drill resistance and patented key control on a core-based system instead, the BEST 1CDF is a drill resistant preferred patented interchangeable core, 7-pin, brass, in the 150 Series. Both give 7-pin capacity; the difference is that the 606K76 stays inside the existing Corbin Russwin mortise cylinder while the 1CDF requires interchangeable core housings.
14) Is the 606K76 a genuine Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin cylinder hardware, which matters with a proprietary keyway like 57A2 since the plug has to match the factory keyway section and X Class pinning to stay inside your key control program.
