Corbin Russwin CR8000-L4 626 – Frequently Asked Questions

1) Is the Corbin Russwin CR8000 a whole cylinder or just the interchangeable core?

Core only. The CR8000 is the 6-pin large format interchangeable core itself, so the lock, exit device, or cylindrical set on the door already has to be built to take a Corbin Russwin large format core. Two operating keys and one control key come with it. The control key is the piece that matters on day one: it retracts the core's lug so you can pull the old core and drop this one in.

2) How do I know which keyway to order on a Corbin Russwin 8000 Series core?

Match the keyway your building is already keyed to, or the core will not accept your keys no matter how it is pinned. The 8000 Series core is offered in 92 keyways, covering the numbered families (252, 27 and its A/B variants, the 57, 59, 62D1, 67, 70, 77, 97, 98, 981, 982, 983 and 99 keyways), the N1 through N28 range, D1 through D4, H01 through H03 and H1 through H8, L1 through L4, plus G, AR, BL and BR. If you are extending an existing Corbin Russwin system, pull an existing key or the system's keying schedule and order that keyway. Starting fresh, pick one keyway and hold it across the whole facility.

3) Our doors use BEST small format cores. Can I drop a Corbin Russwin CR8000 core into them?

No. The CR8000 is a large format core cut for Corbin Russwin hardware and Corbin Russwin key systems, and it will not seat in a housing prepped for a small format figure-eight core. For BEST small format openings, stay with a BEST core such as the 1C 5-pin core, the Peaks 1CB, or the 1CDF drill resistant 7-pin. Mixing formats is the single most common way an interchangeable core order comes back.

4) Will a Corbin Russwin interchangeable core work in my Adams Rite deadlock on an aluminum storefront?

No. Those storefront deadlocks take a threaded mortise cylinder, and the CR8000 is a bare core with no threads and no cam. For an Adams Rite MS style storefront opening, look at the Adams Rite 4036 mortise cylinder, which is Grade 1 and works down to a 1/2 inch minimum door thickness, or a cylinder pull like the 4024 or 4025 where the door is set up for the MS1847 deadlock. Keep the CR8000 for Corbin Russwin hardware prepped for a large format core.

5) The opening is a mortise lock with a threaded cylinder hole rather than a core prep. What cylinder goes in place of the Corbin Russwin CR8000 core?

The Corbin Russwin CR8000 is a large format interchangeable core, so it drops only into hardware prepped to accept that core. Where the lock takes a conventional threaded mortise cylinder, the Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder in the Schlage C keyway. On narrow stile aluminum entrances, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder rated for doors from 1/2 inch minimum thickness. Either of those threads into a standard mortise prep, while the CR8000 route requires the lock body to be core-ready.

6) What is the closest interchangeable core to the Corbin Russwin CR8000 6-pin core from another manufacturer?

The Corbin Russwin CR8000 is a 6-pin large format interchangeable core, non-handed, supplied with two operating keys and one control key so the core can be pulled and replaced without taking the hardware off the door. The nearest counterparts by construction are the Schlage 20-057-C, a full size interchangeable core cylinder furnished in the C keyway and 643E aged bronze finish, and the BEST Peaks 1CB, a 150 Series interchangeable core cylinder. All three work on the same principle of a removable core, but each is cut to its own manufacturer's key system and seats in that manufacturer's core prep, so the deciding factor is which key system the building already runs, not the door itself.

7) What cylinder should be used on a rim exit device instead of the Corbin Russwin CR8000 core?

A rim exit device takes a rim cylinder with a tailpiece cam, which is a different part from the Corbin Russwin CR8000 large format 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, so the choice follows the cam orientation the device calls for. To keep core-swap capability on an exit device, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam that houses a full size interchangeable core.

8) A tenant moved out. Do I have to take the lock off the door to rekey it?

Not with interchangeable core. With the control key you pull the existing core out of the lock and seat a replacement in its place, hardware stays on the door, and the job does not need a locksmith on site. That is the whole point of the 8000 Series core: keep a few spare cores in the right keyway on the shelf and turnover becomes a two minute swap at the door instead of a service call and a lock teardown.

9) Can I use this core in an exit device that takes a rim cylinder?

Only if that device is already fitted with a Corbin Russwin large format interchangeable core rim housing. The CR8000 ships as the core alone, with no cam and no tailpiece, so it cannot go straight into a device drilled for a conventional rim cylinder. Where the device takes a conventional rim cylinder, you want one with the correct tailpiece for that chassis, for example the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal one. If you want interchangeable core on an exit device keyed to Schlage, the 20-057 is a 6-pin core with a convertible tailpiece cam.

10) We want interchangeable core but the campus is keyed Schlage, not Corbin Russwin. What do we order?

Stay in the Schlage family. The CR8000 core is built to key into Corbin Russwin systems, and its keyways are Corbin Russwin keyways, so it will not integrate with a Schlage master key system. For a Schlage full size interchangeable core opening, the 20-057 is the 6-pin FSIC core, and the 20-057-C comes in the C keyway with a 643E aged bronze finish. Order the CR8000 only where the hardware and the key system are both Corbin Russwin.

11) Can Corbin Russwin 8000 Series cores be master keyed into a system we already run?

Yes, provided the keyway matches your existing system and that system was laid out properly to begin with. These are conventional cylinders, so they pin into a standard conventional master key architecture with a change key at the door, a master above it, and room to expand. Six pins gives more usable cuts than a five pin core, which is what buys you the extra levels when a facility grows. Hand the keyway and your keying schedule to whoever maintains your system and have the cores pinned to it.

12) The lever has a key-in-lever cylinder, not an interchangeable core. What replaces it?

Key-in-knob and key-in-lever cylinders are a separate part from the Corbin Russwin CR8000 large format interchangeable core, which ships with two operating keys plus a control key and is pulled with that control key. For hardware built around a key-in-lever cylinder, the Kaba Ilco 1539 is a key-in-knob and lever universal cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series, 6-pin G keyway, keyed different and supplied with two cut keys. Those thread into the knob or lever they were built for, whereas the CR8000 needs a lock prepped for a large format core.

13) What is a higher pin count interchangeable core alternative to the Corbin Russwin CR8000 6-pin core?

The Corbin Russwin CR8000 core is a 6-pin large format interchangeable core built for conventional cylinder master key architectures with room to expand. The BEST 1CDF is a drill resistant, patented interchangeable core with a 7-pin brass construction in the 150 Series, so it carries an extra chamber and patent-controlled key blanks. Both are removable cores, but they belong to different key systems, so moving between them means moving the whole keying scheme, not just the core.

14) The building has Sargent hardware on some doors alongside Corbin Russwin. What cylinder covers the Sargent openings?

The Corbin Russwin CR8000 core is cut to Corbin Russwin keyways, offered across keyway families including the 27, 57, 59, 67, 77 and N series along with L1 through L4 and D1 through D4. For knob and lever hardware built by Sargent, the Kaba Ilco 1579 is a knob and lever cylinder made for Sargent. Mixed-manufacturer buildings normally settle this at the key system level, choosing one system and fitting each door with the cylinder body its hardware accepts.

15) The narrow stile aluminum door has an Adams Rite MS1847 deadlock. Is an Adams Rite cylinder pull a substitute for the Corbin Russwin CR8000 core?

No, those are different parts. The Adams Rite 4024 is a cylinder pull with trim plate mounting for MS1847 deadlock and deadlatch systems, the 4025 is a five pin tumbler cylinder pull with through-screws for the same MS1847 deadlock, and the 4026 is a five pin tumbler cylinder pull for the 5017 wood door deadlock and deadlatch. Each is a door pull with the keyed cylinder built into it, sized and drilled for a specific Adams Rite lock. The Corbin Russwin CR8000 is a large format interchangeable core on its own, meant to be seated in hardware already prepped for a core.

16) What cylinder handles a keyed deadbolt on the same commercial doors as the Corbin Russwin CR8000 core?

The Corbin Russwin CR8000 is a large format interchangeable core for hardware with a core prep. A deadbolt built for a conventional cylinder takes a cylinder made for that body instead, such as the Kaba Ilco 1549 key-in-deadbolt cylinder, which is a deadbolt-function cylinder. The practical split is the prep: doors whose deadbolts accept a large format core stay on the CR8000, and the rest get a cylinder matched to the deadbolt body.

17) Some units have residential handlesets and deadbolts rather than commercial locksets. Does the Corbin Russwin CR8000 core cover those?

The CR8000 core is a commercial large format interchangeable core and needs hardware prepped to accept that core. Residential-style handlesets and deadbolts take rim and retrofit cylinders built for those bodies instead: the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the Emtek CY4 is sold as a single cylinder for Emtek hardware.

18) Do I need to specify left hand or right hand when ordering a CR8000 core?

No hand to call out. The 8000 Series core is non-handed, so the same part goes into a left hand or right hand opening, and a facility can stock one core in one keyway and one finish rather than splitting the shelf. What you do have to specify is the keyway and the finish.

19) Will the core face match the satin chrome levers already on our doors?

626 satin chrome is one of six finishes on the 8000 Series core, alongside 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, and 619 satin nickel. Only the core face and key plug show once it is seated, so match it to the trim it sits in rather than to the door. In commercial work 626 is the finish most buildings are standardized on.

20) Is a 6-pin core worth ordering over a 5-pin one?

Six pins gives you a deeper pool of key combinations and one more pin stack a pick has to defeat, which is why it is the usual choice where a master key system has to grow without running out of changes. The trade off is that the whole system has to be built around it. Five pin cores exist in other formats, like the BEST 1C standard core, and seven pin options like the BEST 1CDF drill resistant core go the other way. Pin count is not something you mix inside one system, so match it to what the building already runs.

21) Is a dummy cylinder an acceptable stand-in for the Corbin Russwin CR8000 core on a door that does not need to be keyed?

They serve opposite purposes. The BEST 12E is a dummy rim cylinder with a 1-5/32 inch diameter, which fills the cylinder opening and matches the look of a keyed door without operating anything. The Corbin Russwin CR8000 is a working 6-pin large format interchangeable core that comes with two operating keys and one control key and turns the hardware into a keyed access point. Use the dummy on inactive leaves and pull-side trim, and the CR8000 wherever the opening actually has to be locked and keyed into the system.

22) The existing trim is satin chrome. Which core finishes match, and how does that compare to a Schlage full size core?

The Corbin Russwin CR8000 core is offered in 626 satin chrome, along with 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed and 619 satin nickel, so it can be matched to the surrounding lever and rose finish across a floor. The Schlage 20-057-C full size interchangeable core is furnished in 643E aged bronze. Where the face of the core is visible in the trim, matching the number on the existing hardware is the deciding detail.
