Corbin Russwin 197K51 L4 626 – Frequently Asked Questions

1) What exactly does the Corbin Russwin 197K51 include, just the plug or a whole cylinder?
Plug only. The 197K51 is the replacement plug portion for the Corbin Russwin 1001 Hotel Mortise Cylinder, so you reuse the existing cylinder housing, cam and mounting hardware. If your housing is damaged or you need a complete cylinder, this part will not get the door working on its own.
2) Which keyways can I get on the Corbin Russwin 197K51 hotel cylinder plug?
Two keyway sections are offered, L3 and L4, both in the Corbin Russwin L keyway family. Pick the one that matches the key section your building is already keyed to, since the plug's keyway sets which key blade will enter.
3) Can I re-key a hotel mortise cylinder by swapping the plug instead of buying a new cylinder?
That is what this part is for. Replacing the 197K51 plug lets you change the key section or refresh a worn plug while keeping the original housing in the lock, which is faster than pulling and replacing the whole cylinder on a run of guest room doors.
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 L3 is a plug-only replacement component for the 1001 Hotel Mortise Cylinder, so it preserves the existing housing. When the housing itself is being replaced, a complete mortise cylinder is required instead: 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. Neither carries the Corbin Russwin L keyway, so a complete-cylinder swap changes the key section for that opening.
5) Is a BEST interchangeable core the same kind of serviceable part as the Corbin Russwin 197K51 plug?
Both let you change key control without replacing the surrounding hardware, but they work differently. The 197K51 L3 is a replacement plug for the Corbin Russwin 1001 Hotel Mortise Cylinder, supplied with the L keyway and fitted into the existing cylinder housing by a locksmith. The BEST 1C5 is a standard 5-pin cylinder core, and the BEST 1CB is a Peaks 1CB 150 Series interchangeable core; those cores are pulled and dropped into BEST interchangeable-core housings rather than rebuilt into a conventional mortise cylinder. A BEST core is not a substitute for the 197K51 plug in a 1001 hotel cylinder.
6) The lock is a rim device, not a mortise cylinder - what should I order instead of the 197K51 plug?
The Corbin Russwin 197K51 L3 plug fits the 1001 Hotel Mortise Cylinder only, so a rim application needs a rim cylinder. The Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, the 20-022 is the same rim 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 rim device requires.
7) What finishes does the 197K51 hotel cylinder plug come in?
Satin brass (606) and satin chrome (626), and both are available in either the L3 or L4 keyway. Match the plug face to the rest of the cylinder and the escutcheon so the serviced door does not stand out from the others on the floor.
8) Can the 197K51 plug be used to re-key a key-in-knob or key-in-lever lockset?
No. The 197K51 L3 is a plug for the Corbin Russwin 1001 Hotel Mortise Cylinder. Key-in-knob and key-in-lever locksets take their own replacement cylinder: the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the 1579 Series is a knob and lever cylinder for Sargent, 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.
9) For a deadbolt cylinder, is the 197K51 plug the right part?
It is not - the 197K51 L3 serves the Corbin Russwin 1001 Hotel Mortise Cylinder. For deadbolt service, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder with a deadbolt function, and on the retrofit side the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts while the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
10) For an aluminum storefront with an Adams Rite deadlock, does a mortise cylinder plug like the 197K51 apply?
No. The 197K51 L3 is a plug for the Corbin Russwin 1001 Hotel Mortise Cylinder in commercial service. Adams Rite storefront deadlocks are keyed through their own cylinder pulls: the 4024 mounts with a trim plate for MS1847 Deadlock/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 5017 wood door deadlock or deadlatch.
11) What looks like a cylinder substitute but will not key anything?
The BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter and is a dummy, so it fills a cylinder hole without operating a lock. The Corbin Russwin 197K51 L3 is the opposite case - a working plug supplied in the L keyway, ordered with L3 or L4 key sections, to restore or re-key a 1001 Hotel Mortise Cylinder.
12) Is there a higher-security alternative if the hotel cylinders are being attacked or picked?
The 197K51 L3 is a genuine Corbin Russwin plug in the L keyway, which gives controlled key section access for hotel and commercial use. Where drill and pick resistance is the driver, the BEST 1CDF is a drill resistant preferred patented interchangeable core with 7 pins in brass, 150 Series, and Medeco offers patented retrofit cylinders such as the 1065140 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. Those are separate keying systems, so moving to them changes the master key plan for the doors involved.
13) Is the 197K51 plug suitable for anything beyond hotels?
It is a commercial-grade part, and the same 1001 hotel cylinders turn up in offices, healthcare, schools, government buildings and multi-tenant residential. Anywhere a Corbin Russwin 1001 hotel mortise cylinder is installed, this plug is the service part for it.
14) Will the 197K51 plug work in a residential Emtek handleset?
No. The 197K51 L3 is a commercial part built for the Corbin Russwin 1001 Hotel Mortise Cylinder. Emtek hardware uses its own cylinder, the Emtek CY4, and for Emtek retrofits Medeco lists the 1065244, a 5-pin rim lazy motion rim type cylinder with an Emtek tailpiece, and the 1065140, a 5-pin retrofit cylinder for Emtek handleset and deadbolt outside cylinders.
