Corbin Russwin 606K79 57B1 626 – Frequently Asked Questions

1) Will the 606K79 plug work in my existing keyway if my system is not 57B1?
No. The 606K79 as supplied is cut for the 57B1 keyway, so the plug only accepts 57B1 keys. A plug is keyway-specific, so if your building is keyed on a different Corbin Russwin section you need the matching plug for that section, not this one. Match the keyway before ordering, because the keyway is what determines whether your existing master and change keys enter.
2) Can a locksmith rekey a Corbin Russwin mortise cylinder with just this plug instead of replacing the whole cylinder?
That is exactly what it is for. Swapping the 7-pin X Class plug into the existing 3 inch mortise cylinder shell lets you change key control on the opening without pulling and replacing the entire cylinder, and it keeps the lock on genuine Corbin Russwin components. The 7-pin X Class architecture is the part that carries the restricted key control, so the plug is what has to change when the keying system changes.
3) I need a complete mortise cylinder, not just the plug - what should I order instead of the Corbin Russwin 606K79?
The 606K79 is a 7-pin Individual X Class plug intended for use inside a 3 inch Corbin Russwin mortise cylinder, so it only replaces the keyed core of an existing cylinder. If you need a whole mortise cylinder to drop into the lock case, the Adams Rite 4036 is a complete mortise cylinder with five-pin security in the 4036 Series, Grade 1, for doors 1/2 inch minimum thickness. The Detex MC65 is another complete mortise cylinder, 1-1/8 inch, 6-pin, with a Schlage C keyway.
4) We want a keying system where maintenance can rekey doors without pulling cylinders - what is the alternative to the Corbin Russwin 606K79 plug?
Swapping the 606K79 plug means disassembling the mortise cylinder and repinning it to the 57B1 keyway. If you want field-changeable keying instead, interchangeable core hardware lets a control key pull the core. The BEST 1CB is a 150 Series interchangeable core cylinder, and the BEST 1CDF is a drill-resistant patented interchangeable core in 7-pin brass, also 150 Series. On the Schlage side, the 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam.
5) Will the 606K79 7-pin plug work in a key-in-lever or key-in-knob lockset?
No. The 606K79 is built for 3 inch Corbin Russwin mortise cylinders, not for knob or lever cylinder housings. For key-in-lever service use a cylinder made for that body, such as the Falcon A23161-05 G, a key-in-lever cylinder with a 6-pin G keyway supplied keyed different with two cut keys. The Kaba Ilco 1539 is a universal key-in-knob and lever cylinder, and the Kaba Ilco 1599 is a key-in-knob replacement cylinder.
6) We have aluminum storefront doors with Adams Rite deadlocks - is the Corbin Russwin 606K79 the right part?
No. The 606K79 plug serves Corbin Russwin 3 inch mortise cylinders. For Adams Rite storefront deadlocks, the 4036 mortise cylinder is a Grade 1 five-pin cylinder for doors 1/2 inch minimum. If the opening needs a pull with an integral cylinder, the Adams Rite 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch systems, and the 4025 is a five-pin tumbler cylinder pull using through-screws for the same MS1847 hardware.
7) Why choose a 7-pin plug over a 6-pin cylinder for a school or hospital keying system?
Pin count drives how many distinct changes a master key system can hold and how tightly duplication can be controlled. The 606K79 runs 7 pins in the Individual X Class configuration, which gives more key control depth than common 6-pin commercial cylinders such as the Detex MC65 6-pin or the Falcon A23161-05 G 6-pin key-in-lever cylinder. For a facility standardizing one restricted system across many doors, the higher pin count and X Class section are the reason to spec it.
8) Would a 5-pin cylinder core do the same job as the 7-pin 606K79 plug?
Pin count is part of the keying system, not a free choice. The 606K79 is a 7-pin Individual X Class plug cut for the 57B1 keyway, so it belongs in a Corbin Russwin 7-pin system. A 5-pin option such as the BEST 1C standard 5-pin cylinder core is a different core format and keying platform, and the BEST 1CDF is the 7-pin interchangeable core in that family. Match the plug to the cylinder body and the existing key system rather than substituting on pin count.
9) The 606K79 comes in Satin Brass and Satin Chrome - what if I need a bronze cylinder to match existing trim?
The 606K79 plug is offered in 606 Satin Brass and 626 Satin Chrome. If the opening calls for a bronze-toned cylinder, the Schlage 20-057-C is a full size interchangeable core cylinder with a C keyway in 643E Aged Bronze. Note that it is a different cylinder format and keyway, so it suits a new or converted opening rather than a Corbin Russwin 57B1 mortise cylinder rebuild.
10) What should I use instead of the 606K79 on a residential handleset or deadbolt?
The 606K79 is a commercial replacement part for Corbin Russwin mortise cylinders and is not intended for residential handleset bodies. For those openings, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders.
11) Is there an equivalent to the 606K79 plug for a Sargent lock?
The 606K79 is a Corbin Russwin cylinder part matched to Corbin Russwin mortise cylinder assemblies and the 57B1 keyway, so it does not cross to other manufacturers' lock bodies. For Sargent knob and lever hardware, the Kaba Ilco 1579 is a knob and lever cylinder made for Sargent. For Emtek hardware, the Emtek CY4 cylinder is sold each, and the Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece.
12) I need a non-keyed filler for an opening that does not require a key - is the 606K79 an option?
No. The 606K79 is a keyed 7-pin plug that accepts the 57B1 keyway, so it always operates by key. Where a cylinder opening needs to be filled without key function, a dummy unit is the right part - the BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter. It fills the prep without providing key operation.
13) For a wood door deadlock, is the 606K79 the correct cylinder part?
The 606K79 plug is a component of a Corbin Russwin 3 inch mortise cylinder and suits mortise lock assemblies. For a wood door deadlock or deadlatch, the Adams Rite 4026 is a five pin tumbler cylinder pull built for Adams Rite 5017 wood door deadlock and deadlatch applications. For a keyed deadbolt cylinder, the Kaba Ilco 1549 is a key-in-deadbolt cylinder.
14) What finishes does the Corbin Russwin 606K79 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder face and the lock trim on the door, since the plug face is visible at the keyhole. Satin Chrome is the usual match for 626 brushed chrome lever and mortise trim; Satin Brass suits 606 brass hardware.
15) Is this Corbin Russwin plug rated for commercial traffic or is it a residential part?
Commercial. The 606K79 is classified as a commercial replacement part and is intended for high-use door hardware in offices, schools, healthcare, government buildings, retail, warehouses and multi-tenant residential. It is not a residential-grade retrofit cylinder part.
16) I need a drill resistant high security cylinder part instead of a standard plug. What else is there?
For drill resistance in a patented restricted system, the BEST 1CDF is a drill resistant preferred patented interchangeable core, 7-pin, brass, 150 Series. That is an interchangeable core rather than a mortise plug, so it only applies if the lock takes a BEST style core. If you are staying in a Corbin Russwin mortise cylinder shell, the 606K79 7-pin X Class plug is the component that fits it.
