Corbin Russwin 606K76 AR 626 – Frequently Asked Questions

1) Will the 606K76 AR plug work with my existing Corbin Russwin keys?
Only if your system is on the AR keyway. This plug is cut for the AR keyway and takes AR key blanks, so it integrates with an existing Corbin Russwin AR keying system. A different Corbin Russwin keyway will not accept AR keys, and the plug is 7-pin, so your keys have to be 7-pin AR cuts.
2) If I need a complete mortise cylinder rather than just a replacement plug, what should I order instead of the Corbin Russwin 606K76 AR?
The 606K76 AR is a 7-pin plug that goes inside an existing Corbin Russwin mortise cylinder housing, so it is not a standalone cylinder. If you need a whole mortise cylinder for the opening, the Detex MC65 is a complete mortise cylinder with a Schlage C keyway, 1-1/8 inch diameter, 6-pin. The Adams Rite 4036 is also a complete mortise cylinder, five-pin, Grade 1, for doors from 1/2 inch minimum thickness. Both of those key to their own keyways rather than the Corbin Russwin AR keyway, so choose them when you are not tied into an existing AR system.
3) What is the difference between the Corbin Russwin 606K76 AR plug and an interchangeable core like the BEST 1CDF?
The 606K76 AR is a fixed 7-pin plug that is pinned and installed inside a Corbin Russwin mortise cylinder housing, so rekeying means disassembling the cylinder. The BEST 1CDF is a 7-pin patented interchangeable core in the 150 series that pulls out with a control key, and the BEST 1C is a standard 5-pin core in the same removable format. Interchangeable cores let you swap keying without taking the lock apart; the 606K76 AR keeps you inside the Corbin Russwin AR keying system you already have.
4) My opening uses a rim exit device, not a mortise lock. Is the 606K76 AR the right cylinder part?
No. The 606K76 AR is built for Corbin Russwin mortise cylinder assemblies. For a rim device you want a rim cylinder: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the 20-022 is the same cylinder with a horizontal tailpiece cam. If the building runs full size interchangeable cores, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Match the cam orientation to what your exit device requires.
5) What finishes is the Corbin Russwin 606K76 AR plug available in?
Two: 606 satin brass and 626 satin chrome. Both are offered in every mortise length from 2-1/4 up to 3 inches. Pick the one that matches the cylinder collar and the lock trim on the rest of the opening, since the plug face is the visible part.
6) Why choose a 7-pin plug over a 5- or 6-pin cylinder for a commercial master key system?
The seventh pin chamber gives you more usable key combinations, which matters when a facility runs a master key hierarchy across a lot of doors. The 606K76 AR is also an Individual X Class plug, meaning it sits at a defined key control level within the Corbin Russwin hierarchy, so it can be pinned into an organized master key system rather than standing alone. Most buildings on 5- or 6-pin cylinders run out of combinations before they run out of doors.
7) I need a mortise cylinder on a Schlage C keyway, not Corbin Russwin AR. What should I look at?
The 606K76 AR plug is AR keyway only and won't serve a Schlage-keyed system. For a Schlage C mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder cut to Schlage C. If the opening is a rim device rather than a mortise lock, the Schlage 20-021 (vertical tailpiece cam) and 20-022 (horizontal cam) are 6-pin rim cylinders.
8) If my facility is standardizing on interchangeable cores instead of maintaining AR-keyed mortise plugs, what is the path?
The 606K76 AR keeps you on the Corbin Russwin AR keyway with a 7-pin plug pinned into the mortise housing. Moving to cores means changing the cylinder format: BEST offers the 1CB Peaks 150 series interchangeable core, the 1CDF drill resistant patented 7-pin brass core in the 150 series, and the standard 5-pin 1C core. On the Schlage side, the 20-057-C is a full size interchangeable core in the C keyway with a 643E aged bronze finish. Pick one core platform and carry it across the facility rather than mixing formats.
9) Can I use the 606K76 AR plug to rekey a key-in-lever or key-in-knob lock?
No. The 606K76 AR is a mortise cylinder plug and the mortise lengths offered are 2-1/4, 2-1/2, 2-3/4 and 3 inch. Key-in-lever and key-in-knob locks take a different cylinder body entirely. For those, the Kaba Ilco 1539 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 for Sargent locks. The Falcon A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway supplied keyed different with two cut keys.
10) Is there a simpler five-pin option instead of the 7-pin 606K76 AR plug?
The 606K76 AR is a 7-pin Individual X Class plug, which raises key combination capacity over 5- and 6-pin cylinders. If a five-pin cylinder is acceptable for the opening, the Adams Rite 4036 is a five-pin Grade 1 mortise cylinder and the BEST 1C is a standard 5-pin core. Those are complete cylinders or cores rather than plugs, and they do not run in the Corbin Russwin AR keyway, so they suit a new or standalone opening rather than one already on an AR master key system.
11) For a narrow stile aluminum storefront door, would I use the 606K76 AR or something else?
The 606K76 AR is a Corbin Russwin mortise cylinder plug and belongs in a mortise cylinder housing in a mortise lock. Narrow stile storefront hardware is usually served by the Adams Rite line: the 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. For a wood door version, the Adams Rite 4026 five pin tumbler cylinder pull is built for the 5017 wood door deadlock and deadlatch.
12) Is this plug suitable for commercial buildings or is it a residential part?
Commercial. The 606K76 AR is built as a commercial-grade cylinder component and is used in offices, schools, healthcare, government buildings, hotels and warehouses running Corbin Russwin mortise locks. Facilities and locksmith crews use it when rekeying or servicing those cylinders rather than swapping whole locks.
13) Is the 606K76 AR a genuine Corbin Russwin part or an aftermarket copy?
Genuine OEM. It's a Corbin Russwin cylinder part, so it fits and functions in Corbin Russwin mortise cylinder assemblies without the tolerance issues that show up when mixing aftermarket plugs into a keying system you need to stay consistent.
14) I need to fill a cylinder hole on a door that is not keyed. Does the 606K76 AR work for that?
No. The 606K76 AR is a working 7-pin keyed plug for Corbin Russwin mortise cylinders. For a non-keyed opening where you only need to fill the prep, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is the part designed for that purpose.
15) Will the 606K76 AR plug work in a residential deadbolt or handleset?
It is a commercial part intended for Corbin Russwin mortise cylinder assemblies, not for residential deadbolt or handleset bodies. For those, Medeco offers retrofit cylinders: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin lazy motion single cylinder for handlesets and deadbolts. Emtek also lists the CY4 cylinder sold each.
