Corbin Russwin 606K77 77A1 626 – Frequently Asked Questions

1) What does the 77A1 keyway mean for keying this plug into an existing master key system?
77A1 is a restricted Corbin Russwin keyway, so the plug only accepts keys cut on that keyway blank. It will integrate into a Corbin Russwin master key system that already uses 77A1, and it will not accept keys from any other Corbin Russwin section. If your building is bitted on a different keyway, order the plug in that keyway instead so the existing master and change keys still operate.
2) I manage a building with Corbin Russwin mortise locks. Can I just swap the plug instead of replacing the whole cylinder?
Yes, if the shell is sound. Rekeying or changing a keyway on a Corbin Russwin mortise lock can be done by changing the 7-pin plug rather than pulling and replacing the entire 2-1/2 inch cylinder, which keeps the housing, cam and collar in place. Replace the whole cylinder instead when the shell is worn, drilled, or the cam is wrong for the lock body.
3) If I need a complete mortise cylinder rather than just a replacement plug, what should I order instead of the Corbin Russwin 606K77?
The Corbin Russwin 606K77 is a 7-pin Individual X Class plug intended to go into an existing 2-1/2 inch Corbin Russwin mortise cylinder, so it is a replacement part rather than a whole cylinder. If the opening needs a complete mortise cylinder, the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security, and the Detex MC65 is a 1-1/8 inch six-pin commercial mortise cylinder cut to the Schlage C keyway. Both arrive as finished cylinders rather than a plug you install into an existing shell.
4) We want keys serviceable without pulling the lock apart. What is the alternative to the Corbin Russwin 606K77 approach?
Replacing the 606K77 plug means removing the mortise cylinder and rebuilding it, since the plug is a replacement cylinder part for commercial mechanical locks. An interchangeable core system swaps the keyed element with a control key instead. The BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill resistant patented interchangeable core 7-pin brass 150 Series core, and the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Those change the housing platform, so they suit rekeying programs planned at the facility level rather than a one-for-one plug swap.
5) What do I order instead of the Corbin Russwin 606K77 for an aluminum storefront with an Adams Rite deadlock?
The 606K77 is a plug for Corbin Russwin mortise cylinders and does not address storefront cylinder pull prep. For Adams Rite MS1847 deadlock and deadlatch systems, the Adams Rite 4024 is a cylinder pull with trim plate mounting and the 4025 is a five pin tumbler cylinder pull with through-screws. For a wood door with an Adams Rite 5017 deadlock or deadlatch, the 4026 five pin tumbler cylinder pull is the matching part.
6) Does the 606K77 plug come keyed, or does a locksmith have to pin and cut it?
Plan on a locksmith finishing it. The 606K77 is a bare Individual X Class plug on the 77A1 keyway, sold as a replacement cylinder component rather than a keyed-and-keys-included cylinder. It gets pinned to your existing keying schedule and the keys cut on 77A1 blanks. If you want a factory-keyed assembly out of the box, a complete cylinder is the better order.
7) I need a cylinder for a rim exit device, not a mortise lock. Is this the right part?
No. The 606K77 is a plug for a mortise cylinder, which threads into the lock body. A rim exit device takes a rim cylinder with a tailpiece. For that, look at the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam or the 20-022 with a horizontal tailpiece cam, and match the cam orientation to your device.
8) If I want to standardize a facility on interchangeable cores instead of rebuilding plugs, what should I look at?
Interchangeable core is a different keying architecture: cores pull with a control key, so rekeying is a swap at the door instead of a bench job on the plug. The BEST 1CB 150 Series interchangeable core, the 1CDF drill-resistant patented 7-pin brass core, or Schlage's 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam are the kinds of parts that support that. Sticking with the Corbin Russwin 606K77 plug and the 77A1 keyway makes sense when the building is already bitted on that system.
9) Is a rim cylinder an acceptable substitute for the Corbin Russwin 606K77 plug?
No. The 606K77 is a mortise cylinder plug dimensioned for 2-1/2 inch Corbin Russwin mortise cylinders. Rim cylinders mount behind the door face and drive a tailpiece instead of a cam in a mortise body. 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. Neither will seat in a mortise lock prep, and neither accepts a Corbin Russwin plug.
10) Which alternative to the Corbin Russwin 606K77 is closest in pin count?
The 606K77 is a 7-pin plug with the 77A1 keyway. Among other cylinder products, the BEST 1CDF is also a 7-pin design, offered as a drill resistant patented interchangeable brass core. Options with fewer pins include the BEST 1C5 standard 5-pin cylinder core and the Adams Rite 4036 five-pin mortise cylinder. Pin count alone does not make a part interchangeable here, since the 77A1 keyway and the 2-1/2 inch Corbin Russwin mortise cylinder body determine what the plug will fit.
11) Can I use the Corbin Russwin 606K77 plug in a key-in-knob or key-in-lever lock?
No. The 606K77 plug is built for 2-1/2 inch Corbin Russwin mortise cylinders. Knob and lever cylinders are a different body entirely: the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the Kaba Ilco 1599 is a key-in-knob replacement cylinder, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent locks, and the Falcon A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway supplied keyed different with two cut keys.
12) We need a non-keyed filler where a cylinder was removed. Does the Corbin Russwin 606K77 work for that?
No. The 606K77 is a keyed 7-pin plug with the 77A1 keyway, intended to restore key control in a working mortise cylinder. For an opening that needs the look of a cylinder without operation, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the dummy option, though it is a rim format rather than a mortise plug.
13) Is the Corbin Russwin 606K77 the right part for a residential handleset or deadbolt retrofit?
It is not. The 606K77 is designated for commercial applications as a Corbin Russwin mortise cylinder part. Retrofit cylinders built for handlesets and residential deadbolts include the Medeco 1012040, a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts; the Medeco 1065140, a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders; the Medeco 1065244, a 5-pin lazy motion rim cylinder with an Emtek tailpiece; and the Medeco 1075127, a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. The Emtek CY4 cylinder is also sold as an individual part.
14) What finishes does the 606K77 mortise cylinder plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the visible cylinder face on the rest of the opening, since the plug face is what shows through the collar. Satin Chrome is the usual choice alongside 626 lever and exit hardware, Satin Brass alongside brass trim.
15) Is this part suitable for a house, or is it commercial only?
It's a commercial component. The 606K77 plug is built for commercial mechanical lock applications, typically offices, schools, healthcare, government buildings and multi-tenant properties where a restricted keyway and a master key system are already in place. For a residential deadbolt or knob, a Kaba Ilco 1549 key-in-deadbolt cylinder or 1599 key-in-knob replacement cylinder is the relevant kind of part.
16) Is the 606K77 a genuine Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin. Model designation is 606K77 77A1, and it is supplied as an authentic Corbin Russwin cylinder component, which matters on X Class restricted keyways where aftermarket plugs generally are not available on the 77A1 section at all.
17) Can I match the Corbin Russwin 606K77 finish to hardware from another line?
The 606K77 plug is offered in 606 Satin Brass and 626 Satin Chrome. Among other cylinder products, the Schlage 20-057-C full size interchangeable core is supplied in 643E Aged Bronze with a C keyway, which is a darker finish family and a different keyway, so it will not blend into a Satin Brass or Satin Chrome Corbin Russwin mortise cylinder assembly.
18) For deadbolt cylinders, what is the equivalent to the Corbin Russwin 606K77?
The 606K77 serves mortise cylinders in commercial mechanical lock hardware, not deadbolts. For deadbolt function, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder listed with a deadbolt function, and the Kaba Ilco 1539 universal knob and lever cylinder is also listed for deadbolt function. Those are complete cylinders for their own housings rather than a plug that drops into a Corbin Russwin mortise shell.
