Corbin Russwin 487K13 77A2 626 – Frequently Asked Questions

1) What is the 77A2 keyway and can I key this plug into my building's existing system?
77A2 is a Corbin Russwin proprietary keyway profile, and the plug is cut for it. If your facility is already keyed on 77A2 under an X Class 7-pin system, this plug can be pinned into that system so one key continues to run the opening. If your masterkey system uses a different Corbin keyway, this plug will not accept those keys.
2) I need to re-key a rim device, not a mortise lock. Is the 487K13 the right part?
No. The 487K13 is a mortise format plug for 1-1/4 inch mortise cylinder housings. Rim exit devices take a rim cylinder with a tailpiece, for example the Schlage 20-021 six-pin rim cylinder with vertical tailpiece cam or the 20-022 with a horizontal cam. If you are standardizing on interchangeable cores instead, the Schlage 20-057 FSIC rim cylinder takes a full size core.
3) If the whole mortise cylinder needs replacing instead of just the plug, what should be ordered?
The Corbin Russwin 487K13 is a replacement plug for 1-1/4 inch mortise cylinder housings, so it only helps if the housing itself is sound and being re-plugged or re-keyed. When the complete mortise cylinder is being swapped, a full cylinder is the right part: 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 five-pin mortise cylinder rated Grade 1. Both are complete cylinders rather than plug components, and both use their own keyways rather than the Corbin Russwin 77A2.
4) For a facility that wants to rekey doors without disassembling cylinders, what is the alternative to a plug like the 487K13?
Swapping the Corbin Russwin 487K13 plug is a bench operation on the 1-1/4 inch mortise cylinder. An interchangeable-core approach lets the core come out 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 in 7-pin brass, and the Schlage 20-057-C is a full size interchangeable core in the C keyway. Those run on their own keying systems, not the Corbin Russwin 77A2 keyway.
5) What finishes does the Corbin Russwin 487K13 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder ring and trim already on the door, since the plug face is the visible part once installed. Satin chrome is the common match for brushed or satin stainless trim, satin brass for brass-finished hardware.
6) Why choose a 7-pin X Class plug over a standard 6-pin cylinder?
The seventh pin and the X Class restricted profile give you key control, meaning keys are not duplicated over the counter, plus added pick resistance. That matters on schools, healthcare, government and multi-tenant buildings where unauthorized key copies are the real security failure. A standard 6-pin commercial cylinder like the Detex MC65 in Schlage C is easier to source and key, but the keyway is open and offers no duplication control.
7) Should I use a fixed keyway plug like this or switch the building to interchangeable cores?
Two different service models. The 487K13 plug is pinned and installed into the mortise cylinder housing, so re-keying means a locksmith at the door with the cylinder apart. Interchangeable core systems, such as the BEST 1C standard 5-pin core or the 1CDF drill resistant 7-pin patented core in the 150 series, let facility staff pull and swap a core with a control key in seconds. Stay with the 487K13 if the building is already on Corbin Russwin 77A2 X Class keying; move to cores only if you are converting the whole facility.
8) How do I identify the right Corbin Russwin plug to order?
Order by model and keyway together: the model is 487K13 with the 77A2 keyway, for a 1-1/4 inch mortise cylinder, then pick the finish (606 satin brass or 626 satin chrome). The pin count and class matter too, this is the 7-pin X Class version, so confirm the cylinder you are servicing is X Class 7-pin before ordering.
9) Is a rim cylinder such as the Schlage 20-021 an acceptable substitute for the 487K13?
No. The Corbin Russwin 487K13 is a plug for a 1-1/4 inch mortise cylinder. The Schlage 20-021 and 20-022 are rim cylinders, differing from each other in tailpiece cam orientation - vertical on the 20-021 and horizontal on the 20-022 - and rim cylinders mount through the door to a surface-applied device rather than threading into a mortise lock body. Different mounting format and a different keyway from the 77A2.
10) What should be used for a key-in-lever or key-in-knob lock instead of a mortise cylinder plug?
The Corbin Russwin 487K13 serves 1-1/4 inch mortise cylinders. Key-in-lever and key-in-knob locksets take a different cylinder format: the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent locks, the 1599 is a key-in-knob replacement cylinder, 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.
11) For a deadbolt cylinder replacement, is the 487K13 the right part?
No. The Corbin Russwin 487K13 is a 7-pin X Class plug for 1-1/4 inch mortise cylinders. Deadbolt cylinder work calls for a deadbolt-function cylinder, such as the Kaba Ilco 1549 key-in-deadbolt cylinder, or the Medeco 1075127, a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. The Medeco 1012040 is a 6-pin lazy motion rim cylinder specific to Kwikset single cylinder deadbolts.
12) How does the 7-pin count of the 487K13 compare with other cylinder options?
The Corbin Russwin 487K13 is a 7-pin X Class plug, and the BEST 1CDF is likewise a 7-pin interchangeable core, in brass with drill resistance. Several alternatives are built on shorter pin stacks: the BEST 1C5 is a standard 5-pin cylinder core, the Adams Rite 4036 is a five-pin mortise cylinder, and the Detex MC65 is 6-pin. Pin count is tied to the keying system in use, so it has to match the master key plan on the building rather than be chosen on its own.
13) Will the 487K13 work in an Adams Rite MS1847 narrow stile deadlock application?
Adams Rite narrow stile deadlocks are served by cylinder pulls built for them: 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 the Adams Rite 5017 wood door deadlock and deadlatch. The Corbin Russwin 487K13 is instead a plug component for 1-1/4 inch mortise cylinders on the 77A2 keyway.
14) Is this Corbin Russwin plug suitable for high traffic commercial doors?
Yes, it is a commercial-duty part. The 487K13 is built for commercial mortise lock assemblies in offices, schools, hospitals, retail, government buildings, multi-tenant residential and warehouses. It is not a residential item, and a homeowner-grade deadbolt cylinder such as the Kaba Ilco 1549 key-in-deadbolt cylinder serves a different job entirely.
15) Is this a genuine Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin. The 487K13 is manufactured as an authentic Corbin Russwin cylinder component to OEM dimensions, which is what keeps it functioning correctly inside a factory mortise cylinder housing. Aftermarket universal cylinders such as the Kaba Ilco 1539 universal key-in-knob or lever cylinder exist for other platforms, but they are not a substitute for a Corbin X Class plug.
16) For a door that needs the look of a keyed cylinder but no locking function, what is used instead?
The Corbin Russwin 487K13 is a working 7-pin plug for commercial mortise cylinders. Where an opening needs the appearance of a cylinder without keyed operation, the BEST 12E Series dummy rim cylinder with 1-5/32 inch diameter fills the prep instead, in rim format rather than mortise.
17) Is the 487K13 suitable for a residential handleset cylinder swap?
The Corbin Russwin 487K13 is specified for commercial use as a replacement part for mortise cylinder assemblies. Residential handleset and interconnected lock retrofits are served by cylinders built for those bodies, such as the Medeco 1065140, a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, the Medeco 1065244 with Emtek tailpiece, or the Emtek CY4 cylinder sold each.
18) The 487K13 comes in Satin Brass and Satin Chrome - what if a darker finish is needed to match existing trim?
The Corbin Russwin 487K13 plug is offered in 606 Satin Brass and 626 Satin Chrome. For a darker cylinder face, the Schlage 20-057-C full size interchangeable core is listed in 643E Aged Bronze, though it is an FSIC core on the Schlage C keyway rather than a 77A2 mortise plug, so it is a finish alternative only where the keying system and cylinder format also change.
