Corbin Russwin 488K99 BL 626 – Frequently Asked Questions

1) Does the 488K99 plug work for both 5-pin and 6-pin keying?
It handles either. The 488K99 accepts both 5-pin and 6-pin arrangements, so a locksmith servicing a mixed system does not have to stock two plugs. Pinning is done at the bench to whatever the existing system uses.
2) Is the Corbin Russwin 488K99 plug a replacement for a whole cylinder, or do I need a complete cylinder instead?
The 488K99 is a replacement plug only - the keyed core component that drops into CK4200, UT5200 (.552") and 2000-051 cylinder assemblies, in 5-pin and 6-pin arrangements. If the housing itself is damaged or you are cylinder-ing a new opening, you need a complete cylinder rather than a plug: the Detex MC65 is a 1-1/8" 6-pin mortise cylinder in Schlage C keyway, and the Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security. Those are assemblies, not plugs, so they do not go into a CK4200 or UT5200 housing.
3) Can I use an interchangeable core instead of a 488K99 plug if I want to rekey without disassembling the lock?
No - the 488K99 is an individual X-Class plug that is serviced inside the CK4200, UT5200 (.552") or 2000-051 cylinder, so rekeying means pinning the plug. If your goal is core swaps by key rather than pinning, that requires an interchangeable-core system: the BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented interchangeable core in 7-pin brass, and the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam. Those are different cylinder platforms and will not accept a 488K99 plug.
4) My opening is an Adams Rite MS1847 deadlock on an aluminum storefront. Does the 488K99 apply?
No. The 488K99 is a Corbin Russwin plug for CK4200, UT5200 (.552") and 2000-051 cylinders. For an MS1847 deadlock or deadlatch, Adams Rite lists the 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws, both designed for use with the MS1847. For a wood door, the Adams Rite 4026 five pin tumbler cylinder pull is designed for the 5017 wood door deadlock/deadlatch.
5) What finishes does the 488K99 cylinder plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Match the plug face to the rest of the cylinder and trim on the opening, since the plug face is the part that shows through the collar.
6) Can I use this plug to rekey a building instead of replacing whole cylinders?
That is what it is for. Swapping plugs in CK4200, UT5200 and 2000-051 cylinders lets you re-establish key control on offices, schools, healthcare and multi-tenant buildings without buying new cylinder bodies or pulling locks off doors beyond removing the cylinder.
7) I need a complete cylinder, not just a plug. What should I look at instead?
The 488K99 is only the plug, so it is the wrong buy if your cylinder body is damaged or you have no Corbin Russwin cylinder in the door yet. For a complete mortise cylinder, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder; for a rim device, Schlage's 20-021 (vertical tailpiece cam) and 20-022 (horizontal cam) are six-pin rim cylinders. For an interchangeable core system, BEST's 1C 5-pin core is a full core rather than a plug.
8) Is the 488K99 an interchangeable core, or does the cylinder have to come apart?
It is an individual X-Class plug, not an IC core, so servicing means pulling the cylinder and changing the plug at the bench. If you want core swaps done at the door without disassembly, a small or full size interchangeable core system is the different animal, for example the BEST 1CB 150 Series interchangeable core or the Schlage 20-057 FSIC rim cylinder.
9) Is the BEST 1C5 core an equivalent to the Corbin Russwin 488K99 plug?
They are both the keyed insert rather than the full housing, but they are not interchangeable. The 488K99 is a 5 and 6-pin X-Class plug in the BL keyway built for Corbin Russwin CK4200, UT5200 (.552") and 2000-051 cylinders. The BEST 1C5 is a standard 5-pin cylinder core from the Standard and Premium Cores line and belongs in BEST housings. Match the plug or core to the cylinder family already in the door.
10) I need to rekey a key-in-knob or key-in-lever lock, not a mortise cylinder. Is the 488K99 the right part?
The 488K99 plug fits Corbin Russwin CK4200, UT5200 (.552") and 2000-051 cylinders. For knob and lever cylinders on other platforms, the peers to look at are the Kaba Ilco 1539 universal key-in-knob/lever cylinder, the Kaba Ilco 1599 key-in-knob replacement cylinder, the Kaba Ilco 1579 knob and lever cylinder for Sargent, and the Falcon A23161-05 G key-in-lever cylinder in RU/T Series 6-pin G keyway, keyed different with two cut keys. Those are complete cylinders for their own lock families, not plugs for a Corbin Russwin housing.
11) What should I order for a rim exit device instead of the 488K99 plug?
Rim exit devices take a rim cylinder, which is a different body style from the CK4200 and UT5200 (.552") cylinders the 488K99 plug serves. Schlage rim options include the 20-021 6-pin rim cylinder with a vertical tailpiece cam and two keys, and the 20-022 6-pin rim cylinder with a horizontal tailpiece cam and two keys - the cam orientation is what matches the device. BEST also lists the 12E Series dummy rim cylinder with a 1-5/32" diameter for openings where no keyed function is needed.
12) Is this plug rated for commercial door traffic or is it a residential part?
Commercial. Corbin Russwin builds the 488K99 to its commercial cylinder parts standard, and the typical use is institutional work: offices, schools, hospitals, government buildings, hotels and mixed-use properties.
13) If I want a keyway other than BL, is there an alternative in this comparable group?
The 488K99 plug is supplied in the BL keyway for Corbin Russwin CK4200, UT5200 (.552") and 2000-051 cylinders, in Satin Brass and Satin Chrome finishes. Where the lock family allows a different keyway, the peers name theirs: the Detex MC65 mortise cylinder is Schlage C keyway, the Schlage 20-057-C is a full size interchangeable core in C keyway with a 643E Aged Bronze finish, and the Falcon A23161-05 G is a 6-pin G keyway. Those keyways belong to their own cylinder platforms, so the choice follows the lock rather than the plug.
