Corbin Russwin 8001-034-77A2 626 – Frequently Asked Questions

1) Will the Corbin Russwin 8001-034-77A2 core work in a CL3329 lockset?
That is exactly what it is built for. The 8001-034-77A2 is a 6-pin interchangeable core made for the Corbin Russwin CL3329 lockset series, so it drops into that lock's core housing without modification. It will not key into another manufacturer's lock, and it will not work in a Corbin Russwin cylinder cut for a different keyway than 77A2.
2) Can I order this Corbin Russwin core keyed to my existing hotel master key system?
The core is supplied in the 77A2 keyway, a proprietary Corbin Russwin keyway that supports restricted duplication and master keying. If your property already runs 77A2, this core can be worked into that system. If your existing cylinders are a different Corbin Russwin keyway section, a 77A2 core will not accept your keys.
3) Can a Schlage 20-207 core be used in place of a Corbin Russwin 8001-034-77A2 core?
No. Both are interchangeable-core cylinders - the Schlage 20-207 is a sub-assembled FSIC core in the S123 keyway, while the Corbin Russwin 8001-034-77A2 is a 6-pin LFIC core cut to the 77A2 keyway and built for the Corbin Russwin CL3329 lockset. The keyways are different proprietary sections, so keys from one system will not enter the other, and the core body is matched to its own housing. Keep Corbin Russwin 77A2 cores in Corbin Russwin CL3329 openings and use the Schlage core in Schlage IC housings.
4) For a hotel guest room where a Schlage IC core is already installed, which core handles room status indication?
The Corbin Russwin 8001-034-77A2 is the one built with a Hotel Indicator Pin for visual guest room status, as a 6-pin LFIC core in the 77A2 keyway. The Schlage 20-207 is a sub-assembled FSIC core in the S123 keyway with no indicator feature stated. If the opening is a Schlage IC housing and you want indication, the Corbin Russwin core is not a drop-in - it belongs in a Corbin Russwin CL3329 lockset, so the lock itself would need to change.
5) What does the hotel indicator pin on this Corbin Russwin core actually do?
It gives visual room status indication at the lock, which is why this core is specified on hotel and hospitality guest room doors rather than plain office openings. If your CL3329 locks do not use the indicator function, you want a standard 6-pin LFIC core instead of the -034 indicator version.
6) Do I need special tools to swap an LFIC core like this?
No. A Less Full Interchangeable Core is removed and replaced with a control key, so a maintenance tech can rekey a guest room door in seconds without pulling the lock apart or drilling anything. That is the whole point of running interchangeable cores on a property with turnover.
7) What else could I use if I am not on a Corbin Russwin keyway?
Stay within the brand if your locks are Corbin Russwin, because the core has to match both the housing and the keyway. If the openings are Schlage instead, the Schlage Commercial 20-207 is an LFIC core in the S123 keyway. It is a different keyway family and a different lock platform, so it is an alternative for a Schlage property, not a substitute in a CL3329.
8) Is the 8001-034-77A2 a whole lock or just the cylinder core?
Core only. It is a replacement cylinder component, so you get the interchangeable core itself, not the lever, chassis, or latch. Order it when the keying needs to change or a core is worn or compromised and the CL3329 lock body is still good.
9) What is the difference between an LFIC core and an FSIC core when ordering a replacement cylinder?
The Corbin Russwin 8001-034-77A2 is supplied as a Less Full Interchangeable Core assembly for the CL3329, exchanged with a control key without special tools. The Schlage 20-207 is sold as a sub-assembled full-size interchangeable core only, in the S123 keyway - a core body on its own. Both approaches support key control programs; the practical difference is which manufacturer's housing and keyway the core is cut for, so confirm the existing lock brand before ordering either.
10) We are standardizing key control across a property on Schlage - does the Corbin Russwin 8001-034-77A2 fit that plan?
Not on the same key system. The 8001-034-77A2 runs the proprietary 77A2 keyway for restricted duplication and is a commercial replacement part for Corbin Russwin CL3329 locksets; the Schlage 20-207 core uses the S123 keyway. A single master key cannot span both sections, so a property standardizing on Schlage IC cores would carry the Corbin Russwin 77A2 cores only for the CL3329 doors that remain, typically hotel guest rooms where the indicator pin is wanted.
11) Is this a full six-pin core or a five-pin?
Six-pin. The extra chamber gives more key differs for a large master keyed property and more depth in the keying system than a 5-pin core. It is a commercial-grade component, not a residential cylinder.
12) Does finish choice affect which of these two cores I can order?
The Corbin Russwin 8001-034-77A2 core is offered in 606 Satin Brass, 626 Satin Chrome, and BSP Black Suede Powder Coat, so you can match the trim on existing CL3329 hardware. Finish does not change keyway or pinning - the 77A2 keyway and 6-pin LFIC configuration are the same across all three. The Schlage 20-207 is identified by its S123 keyway core rather than a finish selection, so match the core to the housing brand first and the finish second.
