Corbin Russwin 488K99 BR 626 – Frequently Asked Questions

1) Is the 488K99 a whole cylinder or just the plug?
Just the plug. The 488K99 is an individual X-Class cylinder plug sold as a replacement component for Corbin Russwin cylinder assemblies. If you need a complete keyed cylinder rather than the core plug, look at a full mortise or rim cylinder instead, such as the Schlage 20-021 rim cylinder with vertical tailpiece cam or the Detex MC65 mortise cylinder.
2) Will the 488K99 plug work in my existing BR keyway master key system?
It carries the Corbin Russwin BR keyway profile, so it pins and keys into an existing BR system on the same keyway. Order it in BR only if your building is already on BR keys; a plug in the wrong keyway will not accept your cut keys.
3) Is the Corbin Russwin 488K99 a complete cylinder or just the plug?
The 488K99 is an individual X-Class cylinder plug - a replacement component that goes into an existing CK4200, UT5200 (.552 inch) or 2000-051 cylinder housing, in 5-pin or 6-pin configuration with a BR keyway. If the job needs a complete cylinder rather than the plug alone, a whole-cylinder part is the right direction: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam supplied with 2 keys, and the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder in the Schlage C keyway.
4) What should I use instead of a 488K99 plug if I want to rekey doors without disassembling cylinders?
The 488K99 plug is rekeyed at the bench, since it is a plug that installs inside a CK4200, UT5200 or 2000-051 cylinder body. For facilities that want key changes without cylinder teardown, an interchangeable-core platform is the alternative: the BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1C5 is a standard 5-pin cylinder core, and the Schlage 20-057 is a 6-pin full-size interchangeable core rim cylinder with a convertible tailpiece cam. Cores pull with a control key rather than requiring the housing to come apart.
5) Will a BEST 1C5 core work in place of a Corbin Russwin 488K99 plug?
No. The 488K99 is a Corbin Russwin X-Class plug cut to the BR keyway and dimensioned for CK4200, UT5200 (.552 inch) and 2000-051 cylinder bodies. The BEST 1C5 is a standard 5-pin cylinder core from BEST's own core system and seats in BEST interchangeable-core housings, not in a Corbin Russwin X-Class cylinder. Both are 5-pin parts that look interchangeable in a bin, but the plug and the core belong to different cylinder platforms.
6) Does the 488K99 take 5-pin or 6-pin?
Both. The plug supports 5-pin and 6-pin configurations, so a locksmith can pin it to whatever depth your system runs. That matters when a facility standardizes on 6-pin for masterkeying headroom while older openings still run 5-pin.
7) I need a cylinder for a key-in-lever lockset, not an X-Class plug. What fits that?
The 488K99 is a plug for CK4200, UT5200 (.552 inch) and 2000-051 cylinder assemblies. For a key-in-knob or key-in-lever cylinder replacement, the Kaba Ilco 1539 is a universal key-in-knob/lever cylinder, the 1579 is a knob and lever cylinder for Sargent locks, the 1599 is a key-in-knob replacement cylinder, and the Falcon A23161-05 G is a key-in-lever cylinder in the RU/T Series 6-pin G keyway, keyed different with 2 cut keys.
8) We need a higher-security replacement than a standard BR plug - what are the options?
The 488K99 is a commercial-grade Corbin Russwin plug in the BR keyway, available in 5-pin and 6-pin. Where a specification calls for patented key control or drill resistance, the BEST 1CDF is a drill-resistant patented interchangeable core with 7 pins in a brass 150 Series body, and Medeco cylinders such as the 1012040 6-pin lazy-motion rim cylinder are built around Medeco's own key system. Those are separate keying platforms, so they will not key alike with existing BR-keyed Corbin Russwin cylinders.
9) What cylinder do I order for an aluminum storefront deadlock rather than a Corbin Russwin X-Class plug?
The 488K99 plug is matched to Corbin Russwin CK4200, UT5200 and 2000-051 cylinders. Storefront deadlocks take their own parts: the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security in the 4036 Series suited to doors from 1/2 inch minimum thickness, and the 4024 and 4025 are cylinder pulls for the Adams Rite MS1847 deadlock/deadlatch, the 4025 mounting with through-screws and the 4024 with a trim plate. For a wood-door deadlock, the Adams Rite 4026 five-pin cylinder pull is made for the 5017 wood door deadlock/deadlatch.
10) I need a deadbolt cylinder, not a 488K99 plug - what are the equivalents?
The 488K99 covers CK4200, UT5200 (.552 inch) and 2000-051 cylinder bodies as a plug only. For deadbolt work, the Kaba Ilco 1549 is a key-in-deadbolt cylinder, 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, and the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and Emtek handleset and deadbolt outside cylinder.
11) What finishes does the 488K99 cylinder plug come in?
Two: 606 satin brass and 626 satin chrome. Pick the one that matches the face of the cylinder and the surrounding trim, since the plug face is the visible part around the keyhole.
12) Is this plug suitable for commercial openings or residential?
Commercial. The 488K99 is built as a commercial-grade mechanical lock component and is used in offices, schools, healthcare, government buildings, retail, warehouses and multi-tenant residential properties where the hardware is commercial spec.
13) Can I use a dummy cylinder instead of a 488K99 plug on a door that is not keyed?
Only where no key function is wanted at all. The 488K99 is a working plug in 5-pin or 6-pin form with a BR keyway, so it carries the keying. The BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills a rim cylinder prep for appearance and does not operate a lock. They serve different purposes and are not substitutes for one another.
14) Does the finish of a 488K99 plug have to match the cylinder it goes into?
The 488K99 is offered in 606 satin brass and 626 satin chrome so the exposed plug face can be coordinated with surrounding hardware. Peer cylinders are sold in their own finishes as well - for example the Schlage 20-057-C is a full-size interchangeable core cylinder in the C keyway with a 643E aged bronze finish. Finish selection is cosmetic coordination; keyway and cylinder platform are what govern fit.
15) Is the Emtek CY4 cylinder an alternative to the Corbin Russwin 488K99?
They address different jobs. The 488K99 is a commercial X-Class plug for Corbin Russwin CK4200, UT5200 (.552 inch) and 2000-051 cylinders. The Emtek CY4 is a cylinder sold individually as an Emtek part, and Emtek-based openings are also served by the Medeco 1065244, a 5-pin rim lazy-motion cylinder supplied with an Emtek tailpiece. Choose by which lock platform is already in the door.
