Corbin Russwin 488K85 57C1 626 – Frequently Asked Questions

1) Can a locksmith re-key an existing Corbin Russwin rim cylinder with this plug instead of replacing the whole cylinder?
That is what it is for. Swapping the plug lets you move a 3000-7 rim cylinder onto a different keyway or key change without buying a new housing, which is the usual approach on cylinder maintenance and re-keying work in commercial buildings.
2) I need a complete rim cylinder, not just a plug — what should I order instead of the Corbin Russwin 488K85?
The 488K85 57C1 is a replacement part — a 7-pin individual X Class plug for the Corbin Russwin 3000-7 rim cylinder — so it only serves you if you are rebuilding or re-keying an existing cylinder housing. For a complete rim cylinder assembly, the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam and 2 keys. Pick the cam orientation your exit device or rim latch requires.
3) My cylinder is a mortise, not a rim — does the 488K85 work?
No. The 488K85 57C1 plug is built specifically for the Corbin Russwin 3000-7 rim cylinder platform. For mortise applications, the Adams Rite 4036 is a five-pin mortise cylinder, Grade 1, in the 4036 series with a 1/2 inch minimum door thickness, and the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway.
4) We want interchangeable cores so we can re-key without tearing down cylinders — what is the alternative to the 488K85?
The 488K85 57C1 plug is serviced at the parts level: you disassemble the 3000-7 rim cylinder to swap or re-pin the plug. If you would rather pull a core, the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam and 2 keys, and the Schlage 20-057-C is an FSIC core in the C keyway, 643E aged bronze. The BEST Peaks 1CB is a 150 series interchangeable core cylinder for small-format housings.
5) Which finishes are available on the 488K85 rim cylinder plug?
Two: 606 Satin Brass and 626 Satin Chrome. The plug face is the visible part once the cylinder is installed, so match it to the existing cylinder ring and exit device trim rather than the door hardware in general.
6) What does X Class mean on a Corbin Russwin 7-pin plug?
X Class is Corbin Russwin's individual key control designation. Ordered as an individual X Class plug, it fits into restricted keyway and master key hierarchies, which is why it shows up on institutional and multi-tenant systems where key control has to be tracked.
7) Does the 488K85 plug come with keys or pins?
It is supplied as the plug itself, a genuine Corbin Russwin service component. Keys, pins, and springs for the key change you are setting up are separate, so plan on having your pinning kit and key blanks in the correct 57C section on hand. Complete cylinders that ship with cut keys, like the Schlage 20-021, are a different purchase.
8) Is a BEST interchangeable core a substitute for the Corbin Russwin 488K85 plug?
No. The 488K85 57C1 is a loose plug that goes inside a Corbin Russwin 3000-7 rim cylinder housing, keyed to the 57C keyway. A BEST core is a self-contained figure-eight core that drops into a BEST housing — the BEST 1C is a standard 5-pin cylinder core and the 1CDF is a drill-resistant patented interchangeable core in 7-pin brass, 150 series. Those serve BEST small-format interchangeable core hardware, not a Corbin Russwin 3000-7 rim cylinder.
9) I am replacing a key-in-lever or key-in-knob cylinder — is the 488K85 the right part?
No. The 488K85 57C1 is a rim cylinder plug for the Corbin Russwin 3000-7. For key-in-lever and key-in-knob work, the Falcon A23161-05 G is a key-in-lever cylinder for RU/T series, 6-pin G keyway, keyed different with 2 cut keys; the Kaba Ilco 1539 is a key-in-knob/lever universal cylinder and the 1579 is a knob and lever cylinder for Sargent. For deadbolts, the Kaba Ilco 1549 is a key-in-deadbolt cylinder and the 1599 is a key-in-knob replacement cylinder.
10) What is the difference between the Corbin Russwin 488K85 plug and a residential rim cylinder like the Medeco lazy motion cylinders?
The 488K85 57C1 is a commercial 7-pin X Class plug for the Corbin Russwin 3000-7 rim cylinder, keyed in the 57C keyway and offered in 606 satin brass and 626 satin chrome with C1 or C2 keying. The Medeco lazy-motion rim cylinders are complete cylinders built for residential deadbolt and handleset hardware: 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 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
11) I need a rim cylinder for a narrow stile aluminum door with an Adams Rite deadlock — what do I use instead of the 488K85?
The 488K85 57C1 plug serves the Corbin Russwin 3000-7 rim cylinder and is not an Adams Rite part. For Adams Rite MS1847 deadlock and deadlatch openings, the 4024 is a cylinder pull with trim plate mounting and the 4025 is a five pin tumbler cylinder pull with through-screws. On wood doors, the Adams Rite 4026 five pin tumbler cylinder pull is made for the 5017 wood door deadlock and deadlatch.
12) I just need a rim cylinder shell that does not have to operate a key — is the 488K85 overkill?
Yes, for a non-operating opening. The 488K85 57C1 is a functioning 7-pin keyed plug for the Corbin Russwin 3000-7 rim cylinder and exists to carry real keying in the 57C keyway. Where you only need to fill the prep and match the look, the BEST 12E series dummy rim cylinder has a 1-5/32 inch diameter and no working key mechanism.
