Corbin Russwin 606K77 67B1 626 – Frequently Asked Questions

1) What keyway is the 606K77 cylinder plug cut for, and can I use my existing Corbin Russwin keys?
The plug comes in the 67B1 keyway. Keys cut on that keyway, including a master keyed or restricted system already using 67B1, will enter it. Keys from a different Corbin Russwin keyway family will not.
2) If I need a complete mortise cylinder rather than just a plug, what should I order instead of the Corbin Russwin 606K77?
The Corbin Russwin 606K77 is a 7-pin Individual X Class cylinder plug for 2-1/2 inch mortise cylinders - it is the plug only, used for rekeying and cylinder rebuilds, not a full cylinder housing. If the opening needs a complete mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder with a Schlage C keyway, and the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security. Both are assembled cylinders that thread into the lock case, so no plug work is required.
3) Is a BEST interchangeable core the same thing as a Corbin Russwin 606K77 plug?
No. The 606K77 is a 7-pin Individual X Class plug that goes inside an existing 2-1/2 inch Corbin Russwin mortise cylinder with the 67B1 keyway. A BEST 1CDF is a drill resistant patented interchangeable core in the 150 Series, and the BEST 1C 5-pin cylinder core and the Peaks 1CB 150 Series core are also complete removable cores. Interchangeable cores drop into a core housing and are pulled with a control key; the 606K77 plug is fitted during a cylinder rebuild.
4) I need a cylinder for a rim exit device, not a mortise lock - what is the alternative to the 606K77?
The 606K77 plug is built for 2-1/2 inch mortise cylinders, so it 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 the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam; the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Match the cam orientation to what the exit device chassis requires.
5) Why choose a 7-pin plug over a 6-pin for a commercial building?
The seventh pin chamber is about key control. A 7-pin Individual X Class plug supports deeper masterkeying hierarchies and restricted key systems, which is what facilities standardizing a campus or multi-tenant building generally want. Six-pin commercial cylinders such as the Detex MC65 in Schlage C keyway are common where key control is handled by the building rather than a restricted keyway.
6) I need a full replacement mortise cylinder, not a plug. What else is there?
For a complete mortise cylinder, the Adams Rite 4036 is a five-pin Grade 1 mortise cylinder, and the Detex MC65 is a 6-pin 1-1/8 inch mortise cylinder in the Schlage C keyway. Neither will keep you on a Corbin Russwin 67B1 key system, so if the building is keyed to 67B1 you want a Corbin Russwin cylinder rather than a cross-brand swap.
7) Can I use the 606K77 plug to convert a lock to an interchangeable core system?
No. This is a conventional mortise cylinder plug, not a core. Interchangeable core work uses a figure-eight core such as the BEST 1C 5-pin standard core or the BEST 1CDF drill resistant 7-pin core, or a full size interchangeable core like the Schlage 20-057 FSIC, and those require an IC-prepped housing.
8) What do I use if the cylinder I am replacing is in a key-in-knob or key-in-lever lock?
The 606K77 is a mortise cylinder plug and does not fit knob or lever cylinder housings. For those, the Kaba Ilco 1599 is a key-in-knob replacement cylinder, the 1539 Series is a key-in-knob and lever universal cylinder, and the 1579 covers knob and lever cylinders for Sargent locks. The Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series with a 6-pin G keyway, keyed different with two cut keys.
9) I have a full size interchangeable core system - can I standardize on the 606K77?
No. The 606K77 is a 7-pin Individual X Class plug tied to the 67B1 keyway and is fitted into a 2-1/2 inch mortise cylinder body. An FSIC program is served by cores such as the Schlage 20-057-C, a full size interchangeable core in the C keyway finished 643E Aged Bronze. FSIC cores are swapped at the door with a control key, while the 606K77 route keeps key control inside the Corbin Russwin X Class system.
10) What if the door needs a cylinder pull on a narrow stile aluminum door instead of a mortise cylinder rebuild?
The 606K77 plug addresses an existing 2-1/2 inch mortise cylinder. Narrow stile openings running Adams Rite deadlocks are served by cylinder pulls: the 4024 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 wood door applications with the 5017 wood door deadlock or deadlatch.
11) I need a non-keyed filler for an unused cylinder hole - does the 606K77 work for that?
No. The 606K77 is a functioning 7-pin keyed plug for 2-1/2 inch Corbin Russwin mortise cylinders and is intended for rekeying and cylinder rebuilds. For a hole that needs to be closed off without key function, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the non-operating option.
12) What is the alternative if the cylinder is going into a residential-style handleset or deadbolt rather than commercial mortise hardware?
The 606K77 is a commercial mortise cylinder plug. Handleset and deadbolt retrofits are covered by Medeco rim type cylinders: the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. The Emtek CY4 cylinder is also sold each.
13) What finishes does the Corbin Russwin 606K77 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder ring and the rest of the trim on the door, since the plug face is the visible part.
14) Is this part suitable for residential door locks?
It is a commercial part. The 606K77 plug is made for Corbin Russwin mortise cylinder assemblies found in offices, schools, healthcare, government buildings and multi-tenant residential. For a house deadbolt or knob, a Kaba Ilco 1539 universal key-in-knob cylinder or a Medeco 1012040 rim cylinder for Kwikset deadbolts is the right shape of part.
15) Does the 606K77 plug come with pins, springs or keys?
Treat it as the plug alone. It is sold as a genuine Corbin Russwin replacement component for rebuilds and rekeying, so a locksmith supplies the pinning and cuts keys to the existing 67B1 system.
16) Does the finish of the 606K77 need to match a replacement cylinder from another brand?
The 606K77 plug comes in 606 Satin Brass and 626 Satin Chrome, so it can be matched to the visible cylinder face already in the door. If the job moves to a complete cylinder instead, finish is part of that part number - the Schlage 20-057-C, for example, is specified in 643E Aged Bronze, which would not match a satin brass or satin chrome cylinder collar.
