Corbin Russwin 8001-034-7-57D1 626 – Frequently Asked Questions

1) Will the Corbin Russwin 8001-034-7 core fit any lock, or only the CL3329?
This LFIC core is built for the Corbin Russwin CL3329 lock series and drops in without modification. It is not a general-purpose core for other housings, so if your lock is a different Corbin Russwin series, order the core specified for that series instead.
2) Does the 57D1 keyway mean my existing Corbin Russwin keys will work?
Only if your system is already on the 57D1 keyway. 57D1 is a proprietary restricted keyway, so a core cut to it will not accept keys from a different Corbin Russwin keyway. Match the keyway stamped on your existing cores or control key before ordering, or the core will need to be keyed to your system.
3) Can a Schlage 20-207 core be used in place of a Corbin Russwin 8001-034-7-57D1 core?
No. Both are interchangeable cores, but they belong to different keyway families. The Corbin Russwin 8001-034-7-57D1 is a 7-pin LFIC cut to the proprietary 57D1 keyway and built for Corbin Russwin CL3329 locks, while the Schlage Commercial 20-207 is a sub-assembled FSIC core in the S123 keyway. A Schlage core will not key into a Corbin Russwin 57D1 master key system, and the cores are not dimensionally interchangeable between the two makers' housings. Choose the 8001-034-7-57D1 when the door and key system are Corbin Russwin.
4) What does the hotel indicator pin on this Corbin Russwin core actually do?
The indicator pin signals guest room occupancy status at the lock, which is why this core is specified for hospitality guest room doors rather than plain office openings. If you do not need occupancy indication, a standard 7-pin core in the same keyway is the simpler part.
5) Can I rekey a Corbin Russwin LFIC core without taking the lock apart?
That is the point of the interchangeable core design. The core swaps out with the control key, so you replace the core rather than disassembling the lockset, which is what makes it workable on high-turnover hotel and apartment doors.
6) Why a 7-pin core instead of a 6-pin for a master key system?
Seven pins give more available key combinations and deeper masterkeying levels than a 5- or 6-pin cylinder, which matters when one facility has to carry change keys, floor masters and a grand master. Cores in a system need to be the same pin count, so a 7-pin building stays 7-pin.
7) Does the Schlage 20-207 core offer a hotel occupancy indicator like the Corbin Russwin 8001-034-7-57D1?
The hotel indicator pin is specific to the Corbin Russwin 8001-034-7-57D1, which integrates it for guest room occupancy visibility in hospitality installations. The Schlage Commercial 20-207 is described as a sub-assembled interchangeable core in the S123 keyway, without that indicator feature. For guest room locks that rely on the indicator function, the Corbin Russwin core is the one to specify.
8) Is this core rated for commercial use or is it a residential part?
Commercial. It is a replacement cylinder part in the Corbin Russwin line, used on hotel guest rooms, schools, healthcare, multi-tenant residential and government buildings running a keying program.
9) How do I choose a finish when matching a replacement core to existing hardware?
Match the core face to the trim already on the door. The Corbin Russwin 8001-034-7-57D1 is offered in 606 Satin Brass, 626 Satin Chrome, and BSP Black Suede Powder Coat, so brass-trimmed hospitality doors, chrome-trimmed commercial openings, and dark-finish hardware can all be matched with the same 7-pin LFIC in the 57D1 keyway.
