Corbin Russwin 574K05 L1 626 – Frequently Asked Questions

1) Will the Corbin Russwin 574K05 plug fit my CK4400 lock?
The 574K05 standard plug is built for Corbin Russwin CK4400 Series locks, plus CK4455 and CK4482 cylinders, with one important exclusion: the CK4429 Hotel function is not covered, and the CK4455 and CK4482 cylinders must be ones manufactured before August 1993. If your CK4455 or CK4482 cylinder is post-8/93 production, this plug is not the right part for it.
2) My Corbin Russwin cylinder is newer than 1993 or a different brand. What should I look at instead?
A 574K05 plug won't serve a post-8/93 CK4455 or CK4482, or hardware from another manufacturer. For key-in-knob and key-in-lever replacements outside that range, the Kaba Ilco 1539 Series is a universal key-in-knob/lever cylinder, and the Kaba Ilco 1599 is a key-in-knob replacement cylinder. For a Sargent lock, the Kaba Ilco 1579 is the knob and lever cylinder made for Sargent. Rim applications are a different part altogether: the Schlage 20-021 (vertical tailpiece cam) and 20-022 (horizontal cam) are 6-pin rim cylinders.
3) Can I use a 574K05 plug to re-key hotel function locks?
No. The CK4429 Hotel function is specifically excluded from the CK4400 Series coverage for this plug. Hospitality properties can use it on other pre-1993 Corbin Russwin CK-series cylinders in the building, but not on the hotel-function lock.
4) I need a whole key-in-lever cylinder, not just the plug. What are the options?
The Corbin Russwin 574K05 L1 is only the plug unit, intended for targeted replacement inside an existing cylinder. For a complete key-in-lever cylinder, the Falcon A23161-05 G is a 6-pin cylinder in the G keyway supplied keyed different with two cut keys for RU/T series levers, and the Kaba Ilco 1599 is a key-in-knob replacement cylinder. Note that neither uses the Corbin Russwin L keyway, so keys will not interchange with an existing L-keyway system.
5) We want cores that can be swapped without disassembling anything. Is the 574K05 L1 that kind of part?
No. Changing a 574K05 L1 plug means opening the Corbin Russwin cylinder to service it, which is why it is sold as an individual standard plug for locksmith and maintenance work. For tool-free core swapping, look at interchangeable core products: the BEST 1CB is a 150 series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented 7-pin interchangeable core in brass, and the Schlage 20-057 is a 6-pin full-size interchangeable core rim cylinder with a convertible tailpiece cam. Those change key control approach, so plan the keying system before standardizing.
6) Does the 574K05 work in both 5-pin and 6-pin Corbin Russwin cylinders?
Yes. The 574K05 plug is made to accept both 5-pin and 6-pin configurations, so a locksmith re-keying a mixed set of CK-series cylinders in one building can use the same plug either way.
7) Do I have to replace the whole cylinder, or can I just swap the plug?
The 574K05 is supplied as an individual standard plug, so you replace only the plug in a worn or damaged CK-series cylinder rather than the complete cylinder assembly. That keeps the existing housing and cam in the door and is the cheaper route when the housing is still sound.
8) I want to standardize a facility on interchangeable cores instead of pinning plugs. What are my options?
Replacing a plug keeps you in a standard pinned cylinder, which means a locksmith visit every time a key is lost. If you would rather rotate cores in-house, look at small format interchangeable core lines such as the BEST 1C Series standard 5-pin core, the BEST 1CB 150 Series core, or the drill-resistant BEST 1CDF patented 7-pin core. Schlage's full size interchangeable core option is the 20-057 FSIC rim cylinder with convertible tailpiece cam. Those require hardware prepped for cores, so it's a retrofit decision, not a like-for-like swap for a 574K05.
9) Can I use the 574K05 L1 in a rim exit device cylinder?
No. The 574K05 L1 plug is matched to Corbin Russwin CK4400 series (excluding the CK4429 Hotel), CK4455, and CK4482 cylinders made before August 1993. Rim applications use a different cylinder format entirely: the Schlage 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and the 20-022 is the same cylinder with a horizontal cam, each supplied with two keys. Pick the rim cylinder by the cam orientation the exit device requires.
10) What is the closest 5-pin alternative if the opening is not a Corbin Russwin CK series lock?
The 574K05 L1 plug supports 5-pin and 6-pin configurations but only fits the designated Corbin Russwin CK4400, CK4455, and CK4482 cylinders. For other openings, the BEST 1C5 is a standard 5-pin cylinder core, the Medeco 1065140 is a 5-pin retrofit cylinder for Arrow JL interconnected locks and Emtek handleset and deadbolt outside cylinders, and the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Match by the lock the cylinder has to enter, not by pin count alone.
11) Is there a mortise cylinder option instead of rekeying the Corbin Russwin plug?
For mortise prep, the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder in the 4036 series with a 1/2 inch minimum door thickness, and the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder in the Schlage C keyway. Both are complete cylinders with their own keyways, whereas the Corbin Russwin 574K05 L1 keeps the existing L keyway system intact by replacing only the plug inside the original CK series cylinder.
12) What should I order for a deadbolt rather than a CK series lever lock?
The Corbin Russwin 574K05 L1 is a plug for CK4400, CK4455, and CK4482 lock cylinders, not a deadbolt part. For deadbolt work, the Kaba Ilco 1549 is a key-in-deadbolt cylinder and the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts. Confirm which deadbolt family is in the door before choosing between them.
13) What finishes does the 574K05 plug come in?
Two: 606 Satin Brass and 626 Satin Chrome. Both are available with any of the L1 through L4 keyways. Match the plug finish to the visible cylinder face on the existing hardware so a re-keyed lock doesn't stand out from the rest of the openings.
14) Is this a genuine Corbin Russwin part or an aftermarket plug?
It's a genuine Corbin Russwin component, a factory replacement part for the designated CK-series cylinders, and it is specified for commercial use rather than residential hardware.
15) I need a non-functioning cylinder for a pull-only door. Can the 574K05 L1 be used unkeyed?
The 574K05 L1 is a keyed plug in the Corbin Russwin L keyway and is intended for working CK series cylinders. Where no key function is wanted, the BEST 12E series dummy rim cylinder with a 1-5/32 inch diameter is the purpose-built choice, and for aluminum or wood door cylinder pull applications the Adams Rite 4025 is a five-pin cylinder pull with through-screws for the MS1847 deadlock while the 4026 is a five-pin cylinder pull for wood door 5017 deadlocks.
16) Is the Emtek CY4 a substitute for the Corbin Russwin 574K05 L1?
No. The Emtek CY4 is a single cylinder sold as a part for Emtek hardware, while the 574K05 L1 is an individual standard plug for commercial Corbin Russwin CK4400, CK4455, and CK4482 cylinders in the L keyway. For Emtek handleset and deadbolt outside cylinders, the Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece. The Corbin Russwin plug and the Emtek parts serve different lock families and are not interchangeable.
