Corbin Russwin 488K99 AR 626 – Frequently Asked Questions

1) What keyway is the Corbin Russwin 488K99 plug cut for, and will it work in my existing master key system?
It is an AR keyway plug. That means it accepts Corbin Russwin AR key blanks and pins into an existing AR master key system. If the building is keyed on a different Corbin Russwin keyway, the AR plug will not take those keys, so match the keyway on the cylinder you are servicing before you order.
2) Is the Corbin Russwin 488K99 AR plug the same thing as a complete replacement cylinder?
No. The 488K99 AR is an individual 5 and 6-pin X-Class plug, a replacement component that drops into existing CK4200, UT5200 (.552 inch) and 2000-051 cylinder housings. If you need a whole cylinder rather than the plug, complete units are a different class of part - for example 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. Those replace the cylinder; the 488K99 AR only replaces the plug inside a Corbin Russwin cylinder.
3) If I want to rekey without disassembling the cylinder, what should I use instead of the 488K99 AR plug?
The 488K99 AR is a plug swap - it requires pulling the Corbin Russwin cylinder apart to service the CK4200, UT5200 or 2000-051 assembly. If your goal is field rekeying by core exchange instead, an interchangeable core platform is the alternative: the BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented interchangeable 7-pin brass core in the 150 Series, and the Schlage 20-057 is a 6-pin full size interchangeable core rim cylinder with a convertible tailpiece cam. Those let you change keying by pulling the core; the 488K99 AR keeps you in the Corbin Russwin AR keyway system you already have.
4) My opening uses an Adams Rite MS1847 deadlock - is the Corbin Russwin 488K99 AR the cylinder part I need?
No. The 488K99 AR is a Corbin Russwin X-Class plug for CK4200, UT5200 and 2000-051 cylinders. For an Adams Rite MS1847 deadlock/deadlatch the cylinder parts built for that lock are the Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws; for an Adams Rite 5017 wood door deadlock/deadlatch it is the 4026 five pin tumbler cylinder pull. The Adams Rite 4036 is a Grade 1 mortise cylinder in the 4036 Series with a 1/2 inch minimum door thickness.
5) Is a cylinder plug the right part, or do I need a whole new cylinder?
A plug like the 488K99 AR is the rotating core of the cylinder, bought when the housing is fine and you are rekeying, converting a keyway, or replacing a worn or damaged plug. If the housing itself is damaged, or you want a different cylinder type entirely, you want a complete cylinder instead, such as the Schlage 20-021 rim cylinder or the Detex MC65 mortise cylinder. Note the plug ships as a component: pins, springs and keys are separate.
6) Can I standardize a whole facility on the 488K99 AR plug?
Yes, where the openings already run Corbin Russwin CK4200, UT5200 or 2000-051 cylinders on the AR keyway. Ordering one plug type for the site keeps rekeying and master keying consistent across doors and lets a locksmith service any opening from the same stock. Mixed keyways in the building are the thing that breaks that plan, so survey the cylinders first.
7) What is the difference between the Corbin Russwin 488K99 AR plug and a BEST 1C5 core?
The BEST 1C5 is a standard 5-pin cylinder core from the BEST Standard and Premium Cores line - a core you insert into a BEST interchangeable core housing. The Corbin Russwin 488K99 AR is a 5 and 6-pin X-Class plug for Corbin Russwin CK4200, UT5200 (.552 inch) and 2000-051 cylinders in the AR keyway. They belong to separate keying platforms, so one does not substitute for the other; match the part to the cylinder family already in the door.
8) Can I use a Kaba Ilco universal cylinder in place of the Corbin Russwin 488K99 AR?
They solve different problems. The Kaba Ilco 1539 is a key-in-knob/lever universal cylinder and the 1579 is a knob and lever cylinder built for Sargent locks - those are complete cylinders sold to replace a cylinder in a knob or lever. The 488K99 AR is only the plug for Corbin Russwin CK4200, UT5200 (.552 inch) and 2000-051 cylinders in the AR keyway, so it is the right part when the housing stays in the door and you are restoring or rekeying within an existing Corbin Russwin AR system.
9) For a residential handleset or deadbolt retrofit, is the Corbin Russwin 488K99 AR the right cylinder part?
It is not the usual choice - the 488K99 AR is a commercial-grade Corbin Russwin replacement plug for CK4200, UT5200 and 2000-051 cylinders. For handleset and deadbolt retrofits the parts built for that duty include the Medeco 1075127, a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1065140 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the Emtek CY4 cylinder.
10) I need a keyed cylinder for a key-in-lever lock, not a plug - what compares to the Corbin Russwin 488K99 AR?
For a key-in-lever cylinder, the Falcon A23161-05 G is a key in lever cylinder in the RU/T series with a 6-pin G keyway, keyed different and supplied with 2 cut keys, and the Kaba Ilco 1599 is a key-in-knob replacement cylinder. The Corbin Russwin 488K99 AR is a different kind of purchase - an individual 5 and 6-pin X-Class plug in the AR keyway that goes inside a CK4200, UT5200 (.552 inch) or 2000-051 cylinder you already have.
11) For a deadbolt cylinder replacement, what takes the place of the Corbin Russwin 488K99 AR?
The 488K99 AR is a Corbin Russwin cylinder plug, not a deadbolt cylinder. Parts catalogued for deadbolt function include the Kaba Ilco 1549 key-in-deadbolt cylinder and the Medeco 1065244, a 5-pin rim lazy motion rim type cylinder with an Emtek tailpiece. Use the 488K99 AR when the work is rebuilding or rekeying a CK4200, UT5200 or 2000-051 cylinder already installed.
12) What finishes is the 488K99 AR plug available in?
Two: 606 Satin Brass and 626 Satin Chrome. Pick the one that matches the cylinder face and the rest of the trim on the opening, since the plug face is visible at the keyhole.
13) Is this a residential part or commercial door hardware?
Commercial. The 488K99 AR is a commercial-grade Corbin Russwin cylinder part, the kind of component stocked for office buildings, schools, healthcare and government facilities running CK4200 or UT5200 keying systems.
14) If an opening only needs the look of a cylinder with no keying, is the Corbin Russwin 488K99 AR appropriate?
No - the 488K99 AR is a functional keyed plug in the AR keyway for Corbin Russwin CK4200, UT5200 and 2000-051 cylinders. Where a non-functioning cylinder is wanted, the BEST 12E Series dummy rim cylinder with a 1-5/32 inch diameter fills the prep without keying. Choose the 488K99 AR only where the cylinder actually operates and needs to stay in your AR master key system.
