Corbin Russwin 8001-034-27B1 626 – Frequently Asked Questions

1) Will the Corbin Russwin 8001-034-27B1 core work in a CL3329 lockset?
That's exactly what it's built for. The 8001-034-27B1 is a 6-pin Less Full Interchangeable Core made for the Corbin Russwin CL3329 lockset, so it drops into that lock's core cavity without pulling the lockset off the door.
2) What does the hotel indicator pin on this Corbin Russwin core actually do?
It supports occupied/vacant room status indication on the lock, which is why this core is specified for hospitality guestroom doors. If your CL3329 openings are hotel rooms with indicator function, this is the core version you want; a standard core without the indicator pin will not drive that feature.
3) What keyway does the 8001-034-27B1 use, and can my existing keys work with it?
It is cut for the Corbin Russwin 27B1 keyway, a proprietary restricted keyway. Your existing keys only operate it if your system is already on 27B1 and the core is keyed into that system. If your building runs a different Corbin Russwin section, the core has to be ordered in that keyway instead.
4) Can I use a Schlage interchangeable core in a Corbin Russwin CL3329 instead?
No. Schlage's 20-207 is an LFIC core, but it is built on Schlage's own S123 keyway and figure-eight core geometry, not Corbin Russwin's. Cores are brand-specific: a CL3329 takes a Corbin Russwin core such as the 8001-034-27B1. Use the Schlage 20-207 only where the lock body itself is Schlage full-size interchangeable core.
5) Can a Schlage 20-207 core be used in place of the Corbin Russwin 8001-034-27B1?
No. Both are interchangeable core cylinders - the Schlage 20-207 is a sub-assembled FSIC core in the S123 keyway, while the Corbin Russwin 8001-034-27B1 is a 6-pin LFIC core built for the Corbin Russwin CL3329 lockset with the 27B1 keyway. The keyways are proprietary to their own manufacturers and will not accept each other's keys, and the Corbin Russwin core carries a hotel indicator pin for occupied/vacant guestroom status that the Schlage core does not. Use the 8001-034-27B1 when the opening is a CL3329 on a Corbin Russwin 27B1 key system; specify the Schlage core only when the building is keyed to a Schlage S123 system.
6) Does this Corbin Russwin core come keyed, or do I need a locksmith to pin it?
It ships as a core component in the 27B1 keyway, not pre-keyed to your system. A locksmith or in-house key control shop pins the 6-pin core to your master/change key schedule, then it swaps into the CL3329 with the control key. That is the point of an interchangeable core: rekeying happens at the bench, not on the door.
7) What finishes can I get this LFIC core in to match the rest of my hardware?
Three: 606 Satin Brass, 626 Satin Chrome, and BSP Black Suede Powder Coat. Pick the one matching the CL3329 trim on the door so the core face doesn't stand out against the rose.
8) Why choose a 6-pin core over a 5-pin for a hotel or campus key system?
Six pin chambers give a much larger set of usable key combinations, which is what you need when a master key system has to cover hundreds of guestrooms or classrooms without cross-keying accidents. The 8001-034-27B1 is 6-pin, and paired with the restricted 27B1 keyway it gives both the combination depth and the duplication control an institutional key system needs.
9) Do I need a control key to change out this interchangeable core?
Yes. A full interchangeable core is retained by the control key, which releases the core from the CL3329 so you can pull it and drop in a replacement. No lock disassembly and no special tools beyond that control key.
10) Is an FSIC core the same thing as the LFIC core used on the CL3329?
They serve the same purpose - a removable core that lets you rekey an opening without pulling the lock off the door - but they are not cross-compatible parts. The Corbin Russwin 8001-034-27B1 is a Less Full Interchangeable Core sized and keyed for the CL3329 lockset in the 27B1 keyway, and the Schlage 20-207 is a sub-assembled full-size interchangeable core in the S123 keyway. Each drops into its own manufacturer's housing. Confirm which housing is in the door before ordering.
11) Is this core rated for commercial traffic or is it a residential part?
Commercial. It is catalogued by Corbin Russwin as a commercial-grade cylinder replacement part, used in hotels, offices, schools, healthcare, multi-tenant buildings and government facilities where managed key control is in place.
