Corbin Russwin 488K99 57D1 626 – Frequently Asked Questions

1) What keyway options are there on the Corbin Russwin 488K99 plug, and does it have to match my existing keys?
Two keyway choices are offered, D1 and D2, within the 57D family. The keyway has to match the Corbin Russwin key blanks and master key system already in the building, otherwise your existing keys will not enter the plug. Pull the keyway stamp from a working cylinder or check your keying schedule before you pick between D1 and D2.
2) Is this a full cylinder or just the plug? Will I get a housing and keys with it?
Just the plug. The 488K99 is an individual X-Class plug, the rotating pin tumbler core that sits inside a CK4200, UT5200 or 2000-051 housing. You supply the housing, pins, springs and cut keys. If you need a complete keyed cylinder instead of a rebuild part, look at a full mortise or rim cylinder such as the Detex MC65 mortise cylinder or the Schlage 20-021 rim cylinder, depending on the lock type.
3) Can I use this Corbin Russwin plug in a Schlage or BEST cylinder?
No. The 488K99 is machined to Corbin Russwin CK4200, UT5200 and 2000-051 dimensions with a 57D keyway, so it will not fit other manufacturers' housings. For a Schlage system use a Schlage part such as the 20-057 full size interchangeable core, and for BEST use a BEST core like the 1C 5-pin standard core.
4) Is the Corbin Russwin 488K99 plug a complete cylinder, or do I need a full cylinder assembly instead?
The 488K99 is a replacement plug only - the 5 and 6-pin X-Class individual plug that goes inside CK4200, UT5200 (.552") and 2000-051 Corbin Russwin cylinder housings. If the housing itself is damaged or missing, you need a complete cylinder rather than a plug: the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway, and the Schlage 20-021 and 20-022 are complete 6-pin rim cylinders with vertical and horizontal tailpiece cams respectively. Those ship as assembled cylinders; the 488K99 is a component for rebuilding one you already have.
5) We want to rekey doors without disassembling cylinders - what should we look at instead of the 488K99?
The 488K99 is a pinned plug that a locksmith rebuilds into a Corbin Russwin CK4200, UT5200 or 2000-051 cylinder, so rekeying means taking the cylinder apart at the bench. For swap-at-the-door rekeying, interchangeable core products are the different approach: the BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1C5 is a standard 5-pin core, and the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. With those, the core pulls with a control key and a new core drops in.
6) Will the 488K99 work in a Sargent or Arrow lock I am servicing?
No. The 488K99 plug is cut for Corbin Russwin CK4200, UT5200 (.552") and 2000-051 cylinder housings with the 57D keyway family, so it is brand-specific. For other manufacturers' locks, the retrofit cylinders are the route: the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder for the RU/T series in the 6-pin G keyway.
7) What finishes does the Corbin Russwin 488K99 plug come in, and does the finish need to match my other hardware?
Two finishes: 606 Satin Brass and 626 Satin Chrome, and both are offered with either the D1 or D2 keyway. The plug face is the only part visible once the cylinder is assembled, so match it to the cylinder housing and trim already on the opening, 626 with satin chrome/brushed nickel hardware and 606 with satin brass.
8) What exact model should I order to get the 57D keyway X-Class plug?
The model designation is 488K99 57D1 from Corbin Russwin, then specify the keyway (D1 or D2) and finish (606 or 626) on the order. Distributors stocking Corbin Russwin keying parts should note this covers both 5-pin and 6-pin pinning, so it is one line item rather than two.
9) What is the difference between ordering the 488K99 plug and a universal key-in-knob replacement cylinder?
The 488K99 is an OEM-style X-Class plug that preserves an existing Corbin Russwin keying system, including master keying, in CK4200, UT5200 and 2000-051 housings, and it comes in 606 satin brass and 626 satin chrome with D1 and D2 keyways. A universal replacement cylinder such as the Kaba Ilco 1539 key-in-knob/lever cylinder or the Kaba Ilco 1599 key-in-knob replacement cylinder swaps the whole cylinder into a variety of lock bodies rather than rebuilding the original, which means the new cylinder's keying replaces what was in the door.
10) I need a keyed cylinder for an Adams Rite deadlock, not a Corbin Russwin plug - what fits?
The 488K99 plug only serves Corbin Russwin CK4200, UT5200 and 2000-051 cylinders, so it has no application in an Adams Rite deadlock. For those openings the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security for doors 1/2 inch minimum thickness, and the cylinder pulls are matched to specific locks: the 4024 and the 4025 five pin tumbler cylinder pull are for the MS1847 deadlock/deadlatch, while the 4026 five pin tumbler cylinder pull is for the 5017 wood door deadlock/deadlatch.
11) The opening needs a keyed-looking cylinder that does not actually operate anything - is the 488K99 right?
No. The 488K99 is a functional pin tumbler plug that provides working cylinder operation inside Corbin Russwin CK4200, UT5200 and 2000-051 housings. When the hole needs to be filled without a working cylinder, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter is the part built for that purpose.
12) Does the 488K99 offer drill resistance or patented key control?
The 488K99 is a commercial-grade X-Class plug built to Corbin Russwin specifications for pin tumbler operation in CK4200, UT5200 and 2000-051 cylinders with the 57D keyway. If the specification calls for drill resistance and patented key control at the cylinder, the BEST 1CDF is a drill resistant preferred patented interchangeable core 7-pin brass 150 Series cylinder, which is a different security platform rather than a variation of the same plug.
13) We are standardizing a facility on one core across all doors - should we buy 488K99 plugs or something else?
The 488K99 keeps existing Corbin Russwin CK4200, UT5200 and 2000-051 cylinders in service on their original keyway, which suits maintaining a system already in place. A facility standardizing on one removable core instead usually moves to interchangeable core hardware, such as the BEST 1CB 150 Series interchangeable core cylinder or the Schlage 20-057-C full size interchangeable core in the C keyway, so every opening takes the same core going forward.
14) Is the 488K99 plug suitable for a commercial building, or is it a residential part?
It is a commercial part. Corbin Russwin cylinder components of this type are used in office buildings, schools, hospitals, government facilities, retail, warehouses and multi-tenant residential where a keyed system is maintained in-house. Facilities keeping a stock of plugs on hand can re-key a compromised cylinder without pulling the lock out of service for long.
15) For a deadbolt or handleset that needs a rim-type lazy motion cylinder, is the 488K99 a substitute?
It is not. The 488K99 is a plug component for Corbin Russwin mortise-style CK4200, UT5200 and 2000-051 cylinders. Lazy motion rim cylinders are a separate style: the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts.
