Corbin Russwin 8001-034-7-57C1 626 – Frequently Asked Questions

1) Will the Corbin Russwin 8001-034-7-57C1 core fit a CL3329 lockset?
Yes. The 8001-034-7-57C1 large format interchangeable core is built for drop-in use in the Corbin Russwin CL3329 series lockset, with no modification to the lock required. Pull the old core with a control key and drop this one in.
2) Do I need my existing keys cut in the 57C1 keyway for this core to work?
Yes. This is a proprietary Corbin Russwin 57C1 keyway core, so it only accepts keys cut on 57C1 blanks. If the rest of your building runs a different Corbin Russwin keyway, this core will not take those keys and will sit outside your existing master key system. Order it only if 57C1 is the keyway your system is already built on, or if you are starting a new restricted system on 57C1.
3) Can I use a Schlage interchangeable core in a Corbin Russwin CL3329?
No. The Schlage Commercial 20-207 is an LFIC core on the Schlage S123 keyway and belongs in Schlage FSIC housings. The Corbin Russwin 8001-034-7-57C1 is the core made for the CL3329 and uses the Corbin Russwin 57C1 keyway. Keep the core brand matched to the lock brand.
4) What does the hotel indicator pin on this Corbin Russwin core actually do?
The indicator pin works with the lock to signal room occupancy status, which is why this core is specified for guest room doors and for healthcare openings where staff need privacy indication at the door. If your CL3329 openings are plain office or storeroom doors with no privacy indication, you do not need the indicator pin version.
5) Is a 7-pin core different from a 6-pin one, and does that change what fits?
The 8001 core here is a 7-pin cylinder, which gives more key differs and deeper masterkeying capacity than a standard 5- or 6-pin cylinder. The pin count has to match your system: a 7-pin core keys into a 7-pin Corbin Russwin system, and it will not operate on keys cut for a 6-pin system in a different keyway.
6) Can I re-key a building without pulling the locks apart?
That is the point of the large format interchangeable core format. The 8001 core comes out and goes back in without specialized tools, so a property manager or locksmith can re-key an individual opening or roll a whole master key system by swapping cores rather than disassembling locksets.
7) What finishes does the Corbin Russwin 8001 LFIC core come in?
Three: 606 satin brass, 626 satin chrome, and BSP black suede powder coat. Pick the one that matches the lever and rose already on the door, since the core face is visible in the opening.
8) Is this core suitable for a hotel or hospital, or is it an office part?
It is a commercial-grade part and gets specified on hotel and hospitality guest room doors, healthcare openings needing privacy indication, schools and government buildings on master key systems, and multi-tenant commercial property. The indicator pin and restricted 57C1 keyway are what make it a hospitality and high-security choice rather than a general office core.
