Corbin Russwin 197K51 59A1 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 197K51 - a full cylinder or just the plug?
It is the plug only, not a complete cylinder. The 197K51 is the replacement plug for the Corbin Russwin 1001 Hotel Mortise Cylinder, so it restores a cylinder you already have in the door rather than replacing the whole housing. If your cylinder shell is damaged or you need a complete mortise cylinder, this is the wrong part to order.
2) Will the Corbin Russwin 197K51 plug work in a standard mortise cylinder, or only the hotel cylinder?
Only the 1001 Hotel Mortise Cylinder. The 197K51 is built as a drop-in for that series specifically, and hotel-function cylinders differ from standard mortise cylinders in how the plug and cam interact. Putting it into a standard mortise cylinder is not a fit the manufacturer supports.
3) Which keyway does the Corbin Russwin 197K51 plug come in?
It is configured for the 59A keyway, and you choose between A1 and A2 when ordering. The plug must match the keyway family already in use on the property, otherwise your existing keys will not enter it and the plug cannot be keyed into the existing system.
4) If the whole 1001 hotel mortise cylinder needs replacing instead of just the plug, what complete mortise cylinder can be used?
The Corbin Russwin 197K51 is a replacement plug only for the 1001 Hotel Mortise Cylinder, so it restores an existing cylinder body rather than replacing it. When the body itself is damaged, a complete mortise cylinder is the correct order: the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security in the 4036 series, and the Detex MC65 is a 1-1/8 inch six-pin commercial mortise cylinder cut to the Schlage C keyway. Both are full cylinders with their own keyways, so they will not follow an existing Corbin Russwin 59A key system the way the 197K51 plug does.
5) Is a BEST interchangeable core an equivalent way to service a Corbin Russwin 1001 hotel cylinder?
No. The Corbin Russwin 197K51 is a plug that drops into the existing 1001 Hotel Mortise Cylinder body and is factory configured to the 59A keyway. BEST small format interchangeable cores such as the 1C 5-pin standard core, the Peaks 1CB 150 series core, or the drill-resistant 7-pin 1CDF are figure-eight cores that require a housing built to accept an interchangeable core. They are a different service model - pull and swap the core - rather than a plug replacement inside a conventional mortise cylinder.
6) What should I order for a rim exit device instead of the 197K51 plug?
The Corbin Russwin 197K51 is a mortise cylinder plug and has no tailpiece or rim cam, so it does not serve a rim exit device. Rim cylinders are the correct part there: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with two keys, the 20-022 is the same cylinder with a horizontal tailpiece cam, and the 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Match the cam orientation to what the exit device chassis requires.
7) What finishes is the 197K51 hotel cylinder plug available in?
Two: 606 satin brass and 626 satin chrome. Both are offered with either the A1 or A2 keyway. Since the plug face is the visible part of the cylinder, match it to the existing cylinder ring and trim so a serviced door does not stand out from the rest of the floor.
8) Does the 197K51 plug come already keyed, or does a locksmith need to pin it?
It ships as a factory plug configured to the 59A keyway, which sets the keyway profile only. The pinning to your specific key change or masterkey schedule is bench work for a locksmith, so plan on pinning it into your existing system before it goes back in the door.
9) Can I swap in an interchangeable core instead of replacing the plug on a hotel cylinder?
Not in the same housing. The 1001 hotel cylinder is a conventional keyed cylinder serviced by replacing its plug; interchangeable core systems like the BEST 1C five-pin core or the 1CB 150 Series core require an IC-prepped cylinder housing. Moving a property to IC means changing the cylinders, not just the plugs.
10) Will a Kaba Ilco universal replacement cylinder work in place of the Corbin Russwin 197K51?
Not for the same opening. The Corbin Russwin 197K51 is a plug for the 1001 Hotel Mortise Cylinder in a 59A keyway, ordered in 606 satin brass or 626 satin chrome with A1 or A2 keying. The Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1599 is a key-in-knob replacement cylinder, the 1549 is a key-in-deadbolt cylinder, and the 1579 is a knob and lever cylinder for Sargent locks. Those are bored-lock and deadbolt cylinders, not mortise cylinder plugs.
11) What cylinder do I use on an aluminum storefront door rather than the 197K51 plug?
The 197K51 plug services a Corbin Russwin 1001 Hotel Mortise Cylinder in a mortise lock body. Aluminum storefront deadlocks take a different part: the Adams Rite 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 deadlock, the Adams Rite 4026 five pin tumbler cylinder pull is built for the 5017 wood door deadlock and deadlatch.
12) I need a cylinder that does not operate anything, just fills the hole - is the 197K51 plug the right choice?
No. The Corbin Russwin 197K51 is a functioning keyed plug configured to the 59A keyway to restore operation of a 1001 Hotel Mortise Cylinder. For a non-operating fill, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is the part built for that purpose.
13) Can I keep the Corbin Russwin 59A key system if I switch to a high security cylinder?
The Corbin Russwin 197K51 plug is factory configured to the 59A keyway specifically so an existing 59A key system stays intact when a 1001 Hotel Mortise Cylinder is serviced. High security alternatives operate on their own restricted systems and will not accept a 59A key - the BEST 1CDF is a drill resistant preferred patented 7-pin brass interchangeable core in the 150 series, and Medeco retrofit cylinders such as the 1065140 5-pin for Arrow JL interconnected locks and Emtek handlesets carry their own keying. Moving to any of those means rekeying the affected doors to a new system.
14) Does the 197K51 plug fit a residential handleset or deadbolt?
No. The Corbin Russwin 197K51 is a commercial part, a plug for the 1001 Hotel Mortise Cylinder. Handleset and deadbolt applications call for a rim type cylinder with a tailpiece: the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1065244 is a 5-pin lazy motion rim cylinder supplied with an Emtek tailpiece. Emtek's own CY4 cylinder is another option for Emtek hardware.
15) Is the Corbin Russwin 197K51 suitable for high-traffic commercial buildings, or is it a residential part?
Commercial. It is catalogued as a commercial-duty Corbin Russwin cylinder part, and the typical uses are hotel and hospitality maintenance, office buildings, schools, healthcare, government facilities and multi-tenant residential where the door hardware sees constant keying traffic.
16) Is a Falcon key-in-lever cylinder a substitute for the Corbin Russwin 197K51?
They serve different lock types. The 197K51 is a mortise cylinder plug for the Corbin Russwin 1001 Hotel Mortise Cylinder in the 59A keyway. The Falcon A23161-05 G is a key in lever cylinder for the RU/T series, 6-pin in the G keyway, keyed different and supplied with two cut keys - it fits a Falcon lever lock chassis, not a mortise cylinder body.
