Corbin Russwin 253K66 AR 626 – Frequently Asked Questions

1) Does the AR keyway mean it will work in my existing Corbin Russwin master key system?
The plug carries the AR keyway profile, so it keys into an existing AR-keyed Corbin Russwin system and keeps keyway consistency across the openings you already maintain. If your building is keyed on a different Corbin Russwin section, you need the plug in that keyway instead, not this one.
2) I need a complete rim cylinder, not a plug. What else do you carry?
Look at a full rim cylinder instead. Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and two keys, and 20-022 is the same cylinder with a horizontal cam. If you want a core you can swap later without pulling the cylinder, the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Note these are Schlage keyways, so they will not run on an existing Corbin Russwin AR key system.
3) If the whole Corbin Russwin 3000 Series rim cylinder needs replacing instead of just the plug, what complete rim cylinder can be used?
The Corbin Russwin 253K66 AR is a replacement plug for 3000 Series rim cylinders, so it only restores the plug and keyway of an existing cylinder body. When the full cylinder is being swapped out, complete rim cylinders include the Schlage Commercial 20-021 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the Schlage Commercial 20-022 6-pin rim cylinder with a horizontal tailpiece cam and two keys. Those are Schlage cylinders on a Schlage keyway rather than the Corbin Russwin AR keyway, so key control changes if you go that route.
4) For a facility that wants keys changed without disassembling cylinders, what is an alternative to rekeying a Corbin Russwin 3000 Series rim cylinder with a 253K66 AR plug?
Replacing the 253K66 AR plug is a bench operation on the existing cylinder body. Facilities that want to change keying by pulling a core instead use interchangeable core hardware: the Schlage Commercial 20-057 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam accepts an FSIC core, and the BEST Peaks 1CB 150 Series interchangeable core cylinder and BEST 1C Series standard 5-pin core are core products for that style of system. That approach changes the keyway and the platform away from Corbin Russwin AR.
5) We need a rim cylinder in a glass storefront door with an Adams Rite deadlock. Is the Corbin Russwin 253K66 AR the right part?
The 253K66 AR is a plug for Corbin Russwin 3000 Series rim cylinders, not a storefront cylinder pull. For Adams Rite deadlock and deadlatch openings, the Adams Rite 4024 cylinder pull mounts with a trim plate for MS1847 deadlock and deadlatch systems, and the 4025 five-pin tumbler cylinder pull uses through-screws for the same MS1847 platform. On wood doors, the Adams Rite 4026 five-pin tumbler cylinder pull is built for the 5017 wood door deadlock and deadlatch.
6) What finishes does the 253K66 AR rim cylinder plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the visible cylinder face on the rest of the door hardware, since the plug face is what shows through the rim cylinder collar.
7) Can I rekey a 3000 Series rim cylinder without buying a new cylinder?
That is the point of this part. Swapping the plug lets a locksmith service or rekey an installed 3000 Series rim cylinder rather than pulling and replacing the whole cylinder, which is how MRO and property maintenance shops keep cost down on a large keyed system.
8) If I want a swappable core system instead of replacing plugs, what should I buy?
An interchangeable core platform saves the plug work entirely. BEST 1C Series is a standard 5-pin core, the 1CB is a 150 Series interchangeable core, and the 1CDF is a drill resistant patented 7-pin brass core in the 150 Series. With cores like those, rekeying an opening means pulling the core with a control key rather than servicing the cylinder plug.
9) Will the 253K66 AR plug work in a Schlage or BEST rim cylinder?
No. It is machined for the Corbin Russwin 3000 Series rim cylinder body and the AR keyway. Schlage rim cylinders such as the 20-021 and BEST interchangeable cores are different platforms entirely and take their own parts.
10) Will a Kaba Ilco 1539 or 1599 cylinder work as a substitute for a Corbin Russwin 253K66 AR?
No. The 253K66 AR is a rim cylinder plug for the Corbin Russwin 3000 Series rim cylinder platform. The Kaba Ilco 1539 Series is a key-in-knob/lever universal cylinder and the 1599 is a key-in-knob replacement cylinder, both catalogued for deadbolt function, so they serve knob and lever locks rather than a rim cylinder body. The Kaba Ilco 1579 is likewise a knob and lever cylinder built for Sargent locks.
11) Is a mortise cylinder like the Adams Rite 4036 or Detex MC65 interchangeable with the Corbin Russwin 253K66 AR?
No. The 253K66 AR is a plug for a rim cylinder, which mounts through the door and drives a rim device tailpiece. The Adams Rite 4036 is a five-pin mortise cylinder in the 4036 Series rated Grade 1 with a 1/2 inch minimum door thickness, and the Detex MC65 is a 1-1/8 inch six-pin mortise cylinder on the Schlage C keyway. Mortise cylinders thread into a mortise lock body and are a different mounting style entirely.
12) What rim cylinder options exist for residential handlesets and deadbolts rather than a commercial Corbin Russwin 3000 Series rim cylinder?
The Corbin Russwin 253K66 AR plug is a commercial part for the 3000 Series rim cylinder platform. For handleset and deadbolt work, Medeco offers rim type lazy motion cylinders: the 1075127 five-pin rim type lazy motion single cylinder for handlesets and deadbolts, the 1012040 six-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, and the 1065244 five-pin rim lazy motion cylinder supplied with an Emtek tailpiece. Each is matched to a specific lock family, so confirm which brand of deadbolt or handleset is on the door.
13) What do I use where a rim cylinder is needed for appearance only and no key function is required?
The Corbin Russwin 253K66 AR is a working plug with an AR keyway used to rekey or restore a 3000 Series rim cylinder. Where no keying is wanted at the opening, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills the prep without key operation. That is a BEST part on the 12E Series platform, so it is not a component of a Corbin Russwin 3000 Series cylinder.
14) Does the Corbin Russwin 253K66 AR offer drill resistance or patented key control like the BEST 1CDF?
The 253K66 AR is described as a commercial-grade OEM-compatible plug built to Corbin Russwin cylinder parts specifications with the AR keyway for consistent key control across a system. If drill resistance and a patented restricted key are the requirement, the BEST 1CDF is a drill resistant preferred patented interchangeable core seven-pin brass cylinder in the 150 Series, which is a different platform and keyway.
15) Can the Corbin Russwin 253K66 AR be used to rekey a key-in-lever lock?
No. The 253K66 AR is engineered exclusively for the Corbin Russwin 3000 Series rim cylinder platform, so its plug dimensions suit a rim cylinder body. For key-in-lever work, the Falcon A23161-05 G is a key-in-lever cylinder for the RU/T Series with a six-pin G keyway, keyed different, supplied with two cut keys. The Medeco 1065140 is a five-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder.
16) Is this plug suitable for commercial door hardware or is it a residential part?
Commercial. It is built to Corbin Russwin's commercial cylinder parts specification and is used in offices, schools, healthcare, government buildings, retail, warehouses and multi-tenant residential properties.
17) We standardize on an interchangeable core with a specific keyway across a building. What is comparable to the AR keyway plug approach?
With the Corbin Russwin 253K66 AR, keyway consistency comes from ordering the AR plug for every 3000 Series rim cylinder in the system. An interchangeable core program achieves the same standardization differently: the Schlage Commercial 20-057-C is a full size interchangeable core cylinder on the C keyway in 643E Aged Bronze, and cores such as the BEST 1C Series standard five-pin core are stocked to a chosen keyway and swapped in the field. The 253K66 AR comes in 606 Satin Brass and 626 Satin Chrome for matching adjacent hardware.
