Corbin Russwin 197K51 N1 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 197K51 and does it include the whole cylinder?
The 197K51 is a plug only, not a complete cylinder. It is the replacement plug for the Corbin Russwin 1001 Hotel Mortise Cylinder, so you reuse the existing cylinder shell and housing and swap just the plug. If the shell itself is damaged or you need a new opening outfitted, you need a full mortise cylinder instead.
2) Will the 197K51 plug fit a standard Corbin Russwin mortise cylinder, or only the hotel version?
It is built specifically for the 1001 Hotel Mortise Cylinder platform. Hotel function cylinders carry different plug and cam geometry than a standard mortise cylinder, so do not order the 197K51 as a plug for a conventional 1000 series mortise cylinder. Confirm the housing on the door is a 1001 hotel cylinder before you pull it.
3) Which Corbin Russwin N keyways can I get this hotel cylinder plug in?
The plug is offered across the full N keyway family, N1 through N28, so a locksmith can match whatever section the property's existing Corbin Russwin system is keyed to. Pick the keyway stamped on the original plug or listed on the building's keying schedule; a plug in the wrong section will not accept the master or change keys already in the field.
4) If the whole 1001 hotel mortise cylinder needs to be replaced instead of just the plug, what complete mortise cylinder can be used?
The Corbin Russwin 197K51 is a plug only for the 1001 Hotel Mortise Cylinder, so it restores an existing cylinder body rather than replacing it. When the cylinder itself is being swapped out, a complete mortise cylinder is the Detex MC65, a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, or the Adams Rite 4036 mortise cylinder, a Grade 1 five-pin unit in the 4036 Series. Both are full cylinders with their own keyway, so the opening moves off the Corbin Russwin N keyway system and would need to be rekeyed into the site's key plan.
5) Can I rekey a hotel guest room lock by just replacing the plug instead of the whole cylinder?
That is the point of the 197K51. Swapping the plug restores or changes the keying on a 1001 hotel cylinder without buying a complete cylinder assembly, which is how most hospitality and multi-tenant maintenance shops handle a compromised or worn guest room key section.
6) I need a whole replacement cylinder, not a plug. What else could I use?
If the housing is going too, a complete cylinder is the right buy. For mortise applications the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder. For rim devices, Schlage's 20-021 (vertical tailpiece cam) and 20-022 (horizontal cam) are six-pin rim cylinders, and the 20-057 is a six-pin full size interchangeable core rim cylinder if you want swappable cores. None of these are hotel function and none accept a Corbin Russwin N keyway plug, so they replace the cylinder rather than repair it.
7) Is an interchangeable core a better option than replacing plugs on hotel doors?
Different maintenance model. Plug replacement like the 197K51 keeps the existing Corbin Russwin 1001 hotel cylinders and N keyway system intact. An interchangeable core system, such as the BEST 1C five-pin core or the 1CB 150 Series core, lets you pull and swap a core with a control key instead of disassembling a cylinder, but converting to it means changing the cylinder housings throughout the facility, not just the plugs.
8) Is a Schlage 20-021 rim cylinder a substitute for the Corbin Russwin 197K51 plug?
No. The Schlage Commercial 20-021 is a complete 6-pin rim cylinder with a vertical tailpiece cam, and the companion 20-022 is the same rim cylinder with a horizontal tailpiece cam. Rim cylinders mount through the door face and drive a rim device; the Corbin Russwin 197K51 is a replacement plug that goes inside an existing 1001 Hotel Mortise Cylinder body with an N keyway. The two are different levels of assembly and different mounting formats, so one cannot stand in for the other.
9) For a hotel that wants to rekey rooms without pulling cylinders, what interchangeable core option exists instead of replacing plugs?
Plug replacement on the Corbin Russwin 197K51 route means servicing each 1001 Hotel Mortise Cylinder itself. A facility that wants core swaps instead can standardize on an interchangeable core platform: the BEST 1C Series standard 5-pin cylinder core, the BEST Peaks 1CB 150 Series interchangeable core, or the BEST 1CDF drill resistant patented 7-pin brass core in the 150 Series. Schlage's equivalent is the 20-057 6-pin FSIC rim cylinder with convertible tailpiece cam, or the 20-057-C full size interchangeable core in the C keyway with a 643E aged bronze finish. Moving to any of these is a hardware conversion, not a like-for-like part swap into the 1001 body.
10) What should be used for a key-in-knob or key-in-lever lock rather than the 197K51 plug?
The Corbin Russwin 197K51 plug fits the 1001 Hotel Mortise Cylinder and nothing else. Key-in-knob and key-in-lever locks take a different cylinder format: the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the 1599 Series is a key-in-knob replacement cylinder, and the 1579 Series is a knob and lever cylinder made for Sargent locks. For Falcon, the A23161-05 G is a key-in-lever cylinder for the RU/T series with a 6-pin G keyway, keyed different with two cut keys. Deadbolt applications take the Kaba Ilco 1549 Series key-in-deadbolt cylinder.
11) Will the Corbin Russwin 197K51 plug work in an aluminum storefront deadlock?
No. The 197K51 is a plug for the Corbin Russwin 1001 Hotel Mortise Cylinder and is supplied in N keyway variants across N1 through N28 in 606 satin brass and 626 satin chrome. Aluminum storefront deadlocks use their own cylinder hardware: the Adams Rite 4036 is a five-pin mortise cylinder rated Grade 1 with a 1/2 inch minimum door thickness, and the Adams Rite 4024 and 4025 cylinder pulls are built for the MS1847 deadlock and deadlatch, the 4025 using through-screws and the 4024 a trim plate mounting. For a wood door deadlock, the Adams Rite 4026 five-pin cylinder pull suits the 5017 wood door deadlock and deadlatch.
12) What finishes does the 197K51 hotel cylinder plug come in?
Two: 606 satin brass and 626 satin chrome. On a mortise cylinder the plug face is the visible part inside the ring, so match it to the ring and trim already on the guest room door rather than to the lockset body.
13) Is this a commercial part or will it work on residential doors?
It is a commercial component for Corbin Russwin 1001 hotel mortise cylinders, used in hotels, offices, healthcare, schools, and multi-tenant residential buildings. Residential deadbolts and knobs do not take a mortise hotel plug at all.
14) Is the 197K51 a genuine Corbin Russwin part or an aftermarket copy?
It is an authentic Corbin Russwin cylinder component built to the brand's own commercial standards, which matters when the plug has to pin and key alongside the rest of an existing Corbin Russwin system.
15) Is there a non-keyed option if the opening only needs to look like it has a cylinder?
The Corbin Russwin 197K51 is a keyed plug carrying an N keyway for the 1001 Hotel Mortise Cylinder, so it always operates. Where the opening needs the appearance of a cylinder without key function, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter serves that purpose. It is a rim format part, so it mounts differently from a mortise cylinder and is not a drop-in for the 1001 platform.
16) Can a Medeco retrofit cylinder replace the 197K51 plug in a hotel guest room mortise lock?
Not directly. The Medeco retrofit cylinders in the set are built for residential-style handleset and deadbolt hardware: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, and the 1065244 and 1075127 are 5-pin rim type lazy motion cylinders, the 1065244 supplied with an Emtek tailpiece. The 197K51 is instead a plug that drops into the existing Corbin Russwin 1001 Hotel Mortise Cylinder body and keeps the N keyway system intact.
