Corbin Russwin 334K00 L1 626 – Frequently Asked Questions

1) What exactly is the Corbin Russwin 334K00 plug, and does it come as a complete core?
It's just the plug, the rotating barrel that the key enters, sold as a single standalone component for the Corbin Russwin 8000-6 interchangeable core system. You are not getting a finished, keyed core. Locksmiths buy this to rebuild or rekey an existing 8000-6 IC core rather than replace the whole assembly. If you need a drop-in core ready to go, a complete interchangeable core is the part to order instead.
2) Will the 334K00 plug work in a 6-pin core, or only 5-pin?
Both. The 334K00 plug is chambered to support 5-pin and 6-pin arrangements, so the same plug covers a standard 5-pin keying setup or a 6-pin system where the extra chamber is used for added master keying levels or a higher security tier.
3) Which Corbin Russwin keyways can I get this plug in?
The L keyway family, in L1, L2, L3 and L4. The keyway has to match the keys already cut for your system, so pull the keyway stamp off an existing key or core before you pick. A plug in the wrong L section will not accept your keys even though the plug body is otherwise identical.
4) Can I use this plug in a BEST or Schlage interchangeable core?
No. The 334K00 is built to the Corbin Russwin 8000-6 interchangeable core geometry and the Corbin Russwin L keyway, and it will not interchange with other manufacturers' core platforms. For a BEST small format core, the BEST 1C Series 5-pin core or the 1CB 150 Series interchangeable core is the part to look at; for Schlage full size IC, the 20-057 FSIC core.
5) If a Corbin Russwin 8000-6 interchangeable core is damaged beyond the plug, what complete core can be used instead of the 334K00 plug?
The 334K00 L1 is an individual standard plug for the 8000-6 interchangeable core, supplied as a single standalone plug for targeted service rather than a whole core. When the core body itself is compromised, a complete interchangeable core is the replacement: the BEST 1CB Peaks 150 Series interchangeable core cylinder and the BEST 1C Series standard 5-pin cylinder core are both sold as finished cores rather than loose plugs. Those are BEST small format cores and key to BEST keyways, so they suit an opening being converted to a BEST system rather than one staying on Corbin Russwin L keyways.
6) What is the difference between the Corbin Russwin 334K00 plug and a full size interchangeable core like the Schlage 20-057-C?
The 334K00 L1 is a cylinder replacement part - the plug alone, built for the Corbin Russwin 8000-6 interchangeable core in 5-pin and 6-pin arrangements with the L keyway. The Schlage 20-057-C is a full size interchangeable core cylinder in the C keyway, furnished in 643E aged bronze. One is a component you install inside an existing core; the other is a complete core you drop into a housing. They also sit on different keyway families, so the Schlage core will not operate keys cut to a Corbin Russwin L keyway.
7) I need a rim cylinder for an exit device, not a plug. What should I order instead of the 334K00?
The 334K00 L1 is an interior plug for an 8000-6 interchangeable core and will not mount to a rim device on its own. For a rim application, the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with two keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam. If the opening is to stay on an interchangeable core program, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Match the cam orientation to the device you are fitting.
8) What finishes does the 334K00 IC core plug come in?
Two: 606 satin brass and 626 satin chrome. The plug face is the only part of it a user sees once the core is assembled, so most people match it to the core housing and the lock trim already on the door. Satin chrome pairs with 626 levers and locksets, satin brass with 606.
9) Do I get pins, springs and a key with the 334K00 plug?
No, it ships as the individual plug only. Pin stacks, springs, the core shell and cut keys are separate, so a locksmith rebuilding a core orders the pinning kit and key blanks alongside it. Plan the keying before you order so you know how many chambers you are loading, 5 or 6.
10) I'm standardizing a building on Corbin Russwin L keyway. Does ordering this plug keep my existing master key system intact?
Yes, provided you order the same L section your system was built on. The plug carries the Corbin Russwin L keyway for controlled key compatibility, so a rebuilt core drops back into the existing hierarchy without recutting keys. Mixing L1 and L3 plugs across the same facility splits your keyway and breaks that.
11) Will a mortise cylinder work in place of the Corbin Russwin 334K00 L1 plug?
No - a mortise cylinder is a threaded standalone cylinder that screws into a mortise lock case, while the 334K00 L1 is the plug that sits inside a Corbin Russwin 8000-6 interchangeable core. If the lock actually takes a mortise cylinder, the Detex MC65 is a 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 rated for doors from 1/2 inch minimum thickness. Both key to their own keyway families rather than the Corbin Russwin L keyway.
12) I need to rekey a key-in-lever lock, not an interchangeable core. Is the 334K00 the right part?
Not for that application. The 334K00 L1 is a plug for the Corbin Russwin 8000-6 interchangeable core system. For a key-in-knob or key-in-lever body, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, the 1579 is a knob and lever cylinder for Sargent locks, and the 1599 is a key-in-knob replacement cylinder. On a Falcon RU/T lever, the Falcon A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway, keyed different with two cut keys. Choose by the lock body brand you are servicing.
13) Is there a higher-security core option than a standard 334K00 plug for a high-risk opening?
The 334K00 L1 is a standard plug for the 8000-6 interchangeable core, supporting 5-pin and 6-pin arrangements in the L keyway with no patented or drill-resistant feature stated. Where a facility wants patented key control and drill resistance, the BEST 1CDF is a drill resistant preferred patented interchangeable core in 7-pin brass, 150 Series. It is a complete BEST-format core on a BEST keyway, so it changes the keying system rather than serving the existing Corbin Russwin L program.
14) Will the 334K00 L1 plug fit an Adams Rite storefront deadlock?
No. The 334K00 L1 is a plug for the Corbin Russwin 8000-6 interchangeable core and is not a storefront cylinder assembly. For Adams Rite MS1847 deadlock and deadlatch systems, the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull using through-screws. For a wood door, the 4026 five pin tumbler cylinder pull is designed for the Adams Rite 5017 wood door deadlock and deadlatch. Select by the lock the door already carries.
15) What should I use instead of the 334K00 for a residential handleset or deadbolt retrofit?
The 334K00 L1 is specified for commercial applications as part of the Corbin Russwin 8000-6 interchangeable core system. For handleset and deadbolt retrofits, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders. Emtek owners can also use the Medeco 1065244, a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece, or the Emtek CY4 cylinder sold each.
16) Is this a commercial part or is it fine for a house?
It's a commercial cylinder component. Corbin Russwin 8000-6 IC hardware shows up in offices, schools, hospitals, government buildings, retail and multi-tenant residential, where the point of interchangeable cores is that a facility can rekey a door in seconds without pulling the lock. A single-family home with standard residential deadbolts has no 8000-6 core to put this plug into.
17) I need a non-keyed filler for an opening that does not need to lock. Does the 334K00 come as a dummy?
The 334K00 L1 is a working standard plug for the 8000-6 interchangeable core and is keyed to the Corbin Russwin L keyway. For a non-functioning filler, the BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter and is built to fill a rim cylinder opening without providing key operation. Use the dummy only where no locking function is required.
18) For a key-in-deadbolt cylinder replacement, is the Corbin Russwin 334K00 an option?
The 334K00 L1 serves the 8000-6 interchangeable core rather than a deadbolt cylinder housing. For deadbolt function, the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, and the 1539, 1579 and 1599 Series cylinders are also catalogued with a deadbolt product function. Confirm the lock body brand before ordering, since these are specific to the housings they were designed for.
