Corbin Russwin 197K51 H1 626 – Frequently Asked Questions

1) What keyways can I order the 197K51 hotel cylinder plug in?
Eight keyway sections are offered: H1 through H8. Pick the one that matches the section already running in your Corbin Russwin system so the plug falls under your existing master keying rather than forcing a new key section on the guest room doors.
2) Can a Detex MC65 mortise cylinder be used instead of a Corbin Russwin 197K51 plug?
No - they are different kinds of part. The Corbin Russwin 197K51 is supplied as the plug only, for targeted replacement of a worn or damaged plug inside an existing 1001 Hotel Mortise Cylinder, and it carries the Corbin Russwin H keyway. The Detex MC65 is a complete 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway. If the cylinder shell and housing in the door are sound and you only need the keyed plug, the 197K51 is the matching component; if you are replacing the whole mortise cylinder and moving to a Schlage C keyed system, the MC65 is the whole-cylinder route.
3) What is the alternative to a Corbin Russwin 197K51 plug if we want to stop rekeying and switch to interchangeable cores?
The 197K51 is a fixed replacement plug for the Corbin Russwin 1001 Hotel Mortise Cylinder, so servicing it means pulling the cylinder and changing the plug. Buyers standardizing on removable cores instead look at interchangeable core products such as the BEST 1CB 150 Series interchangeable core cylinder, the BEST 1CDF drill resistant 7-pin brass 150 Series core, or the Schlage 20-057-C full size interchangeable core in the C keyway. Those let a core be swapped at the door without disassembling the cylinder, but they are a different platform and require the lock to accept an IC housing rather than a 1001 hotel mortise cylinder.
4) Is the Corbin Russwin 197K51 the right part for a rim exit device cylinder?
No. The 197K51 is the plug for a mortise-format cylinder, specifically the Corbin Russwin 1001 Hotel Mortise Cylinder. Rim exit devices take a rim cylinder with a tailpiece cam, such as the Schlage 20-021 6-pin rim cylinder with vertical tailpiece cam, the 20-022 with horizontal tailpiece cam, or the 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam. Confirm the cam orientation the device requires before ordering, since vertical and horizontal are not interchangeable.
5) We have aluminum storefront doors with Adams Rite deadlocks - does the Corbin Russwin 197K51 fit those?
The 197K51 belongs to the Corbin Russwin 1001 Hotel Mortise Cylinder platform and is a plug-only component, not a standalone cylinder for a storefront deadlock. For Adams Rite hardware, the 4036 mortise cylinder is a Grade 1 five-pin mortise cylinder in the 4036 Series with a 1/2 inch minimum door thickness, and the 4024 and 4025 cylinder pulls are made for use with the Adams Rite MS1847 deadlock/deadlatch - the 4024 using trim plate mounting and the 4025 using through-screws. For a wood door deadlock, the 4026 five-pin cylinder pull is intended for the Adams Rite 5017 wood door deadlock/deadlatch.
6) What finishes does the 197K51 plug come in, and will it match my existing cylinder face?
Two finishes: 606 satin brass and 626 satin chrome. Both are available across all eight H keyway sections. Since only the plug face shows once installed, match it to the cylinder ring and lock trim already on the door, 626 for chrome or brushed nickel trim, 606 for brass.
7) Can I rekey a hotel guest room lock by just replacing the plug instead of the whole cylinder?
That is exactly what this part is for. Replacing the plug on a Corbin Russwin 1001 Hotel Mortise Cylinder lets you deal with a worn or compromised plug, or reset a key section, without buying and installing a complete cylinder on every door. For a property manager running a floor of guest rooms, it keeps the shells and cams in place.
8) Is a hotel mortise cylinder plug different from a standard mortise cylinder plug?
Yes. The 1001 Hotel platform this plug belongs to is built for hospitality keying, where guest, maid, master and emergency levels all have to work through one cylinder. That is why the part is designated a Hotel Mortise Cylinder plug rather than a general commercial one, and why it goes into hotels, motels and multi-unit lodging as well as offices, healthcare, schools and government buildings.
9) I need a full mortise cylinder, not a plug. What else is available?
For a complete mortise cylinder rather than a replacement plug, look at the Detex MC65, a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, or the Adams Rite 4036 five-pin mortise cylinder, which is a Grade 1 cylinder with a 1/2 inch minimum door thickness. Neither carries a Corbin Russwin H keyway, so they will not key into an existing Corbin Russwin system.
10) What replaces a key-in-knob or key-in-lever cylinder rather than a hotel mortise cylinder plug?
The Corbin Russwin 197K51 is a plug for a mortise cylinder and does not serve knob or lever lock bodies. For those, the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder and the 1579 Series is a knob and lever cylinder made for Sargent locks, while the 1599 is a key-in-knob replacement cylinder. The Falcon A23161-05 G is a key in lever cylinder in the RU/T Series with a 6-pin G keyway, keyed different and supplied with two cut keys. Match the cylinder to the lock brand and chassis, since knob and lever cylinders are not cross-brand universal.
11) Will the Corbin Russwin 197K51 work in a residential deadbolt or handleset?
It will not - it is a commercial part, supplied as the plug for the Corbin Russwin 1001 Hotel Mortise Cylinder. Residential deadbolts and handlesets use their own cylinder formats: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, the 1065244 is a 5-pin lazy motion rim type cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Kaba Ilco also offers the 1549 Series key-in-deadbolt cylinder for deadbolt function.
12) For a door that needs the look of a keyed cylinder but no key function, is the 197K51 plug the right buy?
No. The 197K51 is a functioning keyed plug in a Corbin Russwin H keyway, intended to restore key operation in a 1001 Hotel Mortise Cylinder. When an opening needs a cylinder appearance without keyed operation, a dummy cylinder is the correct item - for example the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter. Use the 197K51 only where the lock is actually keyed into your Corbin Russwin system.
13) Is a BEST 1C core the same idea as a Corbin Russwin 197K51 plug?
They are both the keyed working element rather than a full lock, but they are not interchangeable. The BEST 1C5 is a standard 5-pin cylinder core from the Standard and Premium Cores line, designed to drop into a BEST interchangeable core housing. The Corbin Russwin 197K51 is a plug that fits inside the Corbin Russwin 1001 Hotel Mortise Cylinder and is offered in H1 through H8 keyways with 606 satin brass and 626 satin chrome finishes. The two belong to separate keying platforms, so choose by which system the building is already keyed to.
14) Can I use an interchangeable core instead of replacing this plug?
Not in a Corbin Russwin 1001 Hotel Mortise Cylinder, which is a conventional fixed-plug cylinder. If you want core-swap rekeying across a property you would be changing to an interchangeable core platform altogether, such as a BEST 1C 5-pin core or the Schlage 20-057 FSIC rim cylinder, which means new cylinders and new keys rather than a plug change.
15) Is the 197K51 plug suitable for commercial and institutional buildings, not just hotels?
It is a commercial-grade part, and the applications run past hospitality into office buildings, healthcare facilities, schools, government and municipal buildings, and multi-tenant residential. Anywhere a Corbin Russwin 1001 Hotel Mortise Cylinder is installed, this is the plug that services it.
