Corbin Russwin 334K01 BL 626 – Frequently Asked Questions

1) Will the 334K01 plug work in a 5-pin master key system as well as a 6-pin?
Both. The plug is configured for 5-pin and 6-pin keying arrangements, so it can be pinned into an existing 5-pin system or a 6-pin master keyed system without switching to a different plug part number.
2) Does the BL keyway on this plug have to match my existing Corbin Russwin keys?
Yes. The plug comes factory-configured in the BL keyway, so it drops into an existing Corbin Russwin BL key system without modification. If your building is keyed in a different Corbin Russwin keyway, the BL plug will not accept your keys and you need the plug cut for your keyway instead.
3) I need a full interchangeable core cylinder, not just a plug - what should I order instead?
The Corbin Russwin 334K01 BL is a replacement plug component for an existing 8000-6 interchangeable core. For a complete core-level product, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and two keys, and the Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway with a 643E Aged Bronze finish. Those are assemblies you install; the 334K01 BL is the plug that goes inside a Corbin Russwin core.
4) Can a BEST 1C core be used in place of a Corbin Russwin 334K01 BL plug?
No. The Corbin Russwin 334K01 BL is an individual X Class plug for the Corbin Russwin 8000-6 interchangeable core, configured for 5-pin and 6-pin keying in the BL keyway. The BEST 1C5 is a complete standard 5-pin cylinder core, not a plug that drops into a Corbin Russwin 8000-6 core body. If you need a whole core rather than the plug component, the BEST 1C5 core or the BEST 1CB 150 Series interchangeable core cylinder are the core-level items; the 334K01 BL only serves an existing Corbin Russwin 8000-6 assembly.
5) For a key-in-lever or key-in-knob lock, is the 334K01 BL the right cylinder?
No. The 334K01 BL is a plug for the Corbin Russwin 8000-6 interchangeable core system. For key-in-knob and key-in-lever cylinders, the Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder, the Kaba Ilco 1599 is a key-in-knob replacement cylinder, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series 6-pin G keyway supplied keyed different with two cut keys.
6) What finishes does the 334K01 plug come in, and does it need to match the lock trim?
Two finishes: 606 Satin Brass and 626 Satin Chrome. Only the plug face shows through the core, so pick the one that matches the core and lock trim already on the door. In a mixed building, satin chrome is the usual match for 626 levers and exit trim, satin brass for 606.
7) Can I use the 334K01 plug to rekey a rim cylinder on an exit device?
Not on its own. This plug is built for the Corbin Russwin 8000-6 interchangeable core platform, so it serves cores that mount in 8000-6 housings. For a straight rim cylinder on an exit device you want a rim cylinder assembly, such as the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal cam, chosen to match the device's cam orientation.
8) What is the difference between the Corbin Russwin 334K01 BL and a mortise cylinder like the Detex MC65?
They sit at different levels of the lock. The 334K01 BL is an individual X Class plug for the Corbin Russwin 8000-6 interchangeable core in the BL keyway, sold as a replacement part. The Detex MC65 is a complete 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway, and the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder. A mortise cylinder threads into the lock body; the 334K01 BL only replaces the plug inside a Corbin Russwin core.
9) Which cylinder do I use for a rim exit device instead of the Corbin Russwin 334K01 BL?
Rim devices take a rim cylinder, which the 334K01 BL is not - it is a plug for the Corbin Russwin 8000-6 interchangeable core. The Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the Schlage 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. Pick the cam orientation your device requires. The BEST 12E Series is a dummy rim cylinder with a 1-5/32 inch diameter for openings where no keyed function is needed.
10) Is there a drill-resistant or patented-key alternative to the Corbin Russwin 334K01 BL plug?
The 334K01 BL is a genuine Corbin Russwin plug in the BL keyway for the 8000-6 interchangeable core, supporting 5-pin and 6-pin keying. If the requirement is a higher-security core rather than a Corbin Russwin plug, the BEST 1CDF is a drill resistant patented interchangeable core with 7 pins in brass, 150 Series. That is a different key system and a complete core, so it is a system change rather than a like-for-like plug swap.
11) Can the Corbin Russwin 334K01 BL be used on an Adams Rite storefront deadlock?
No. The 334K01 BL is a plug for the Corbin Russwin 8000-6 interchangeable core. Adams Rite deadlocks take their own cylinder items: the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws are both for the MS1847 deadlock/deadlatch, the 4026 five pin tumbler cylinder pull is for the 5017 wood door deadlock/deadlatch, and the 4036 is a Grade 1 five-pin mortise cylinder.
12) Will the 334K01 BL work in a residential deadbolt or handleset?
No. The 334K01 BL is a commercial Corbin Russwin part, a plug for the 8000-6 interchangeable core in the BL keyway. For deadbolts and handlesets, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1065244 is a 5-pin lazy motion rim cylinder with an Emtek tailpiece, and the Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. The Emtek CY4 cylinder is sold each as an Emtek part.
13) Is this plug suitable for high-traffic commercial doors like schools and hospitals?
It's a commercial-grade cylinder part, used in office buildings, schools, healthcare, government facilities, multi-tenant residential, warehouses and retail. It is not a residential-duty item.
14) Is the 334K01 a genuine Corbin Russwin part or an aftermarket copy?
Genuine Corbin Russwin cylinder component, made to the tolerances of the 8000-6 interchangeable core platform. That matters on plugs because an out-of-spec plug binds in the core shell and drags on the key.
15) I need a Corbin Russwin 334K01 plug to match satin chrome hardware - is there an option other than satin brass?
Yes. The 334K01 BL plug for the Corbin Russwin 8000-6 interchangeable core is offered in 606 Satin Brass and 626 Satin Chrome, so you can match either finish family across an opening. Both carry the BL keyway and 5-pin and 6-pin keying support. Among other-brand cores, the Schlage 20-057-C full size interchangeable core is offered in 643E Aged Bronze, a different finish direction and a different key system.
