Corbin Russwin CR2000-052-L4-626 – Frequently Asked Questions
1) Can I get a Corbin Russwin 052 cylinder keyed into the master key system already in my building?
That is what the keyway and pin selection is for. The 052 is offered across 84 Corbin Russwin keyways and in 6-pin or 7-pin, so a facility standardized on a given Corbin Russwin keyway can order the 052 on that same keyway and fold it into the existing master key hierarchy. Matching the keyway is not optional: a 6-pin N1 cylinder will not take a key cut on a 57A1 keyway.
2) Is the 2000-052 a full replacement cylinder or just an interchangeable core?
It is a complete conventional cylinder, catalogued as a replacement part for UT5200 and CK4200 Series hardware, not a removable core. Conventional means the pin stack is in the cylinder body, so rekeying is a bench job on the cylinder. If you want to swap keying at the door without disassembly, you want an interchangeable core product such as the BEST 1CB 150 Series interchangeable core or the BEST 1CDF 7-pin drill resistant core instead, but those work in BEST housings, not in a Corbin Russwin key-in-lever.
3) Can I use the Corbin Russwin 052 cylinder in an exit device or a rim application?
No. The 052 is a key-in-lever cylinder, it keys the lever of a UT5200 or CK4200 lock. Rim devices take a rim cylinder with a tailpiece cam: the Schlage 20-021 (6-pin, vertical tailpiece cam) or the 20-022 (6-pin, horizontal cam) cover that, and the Schlage 20-057 is the full size interchangeable core rim version. A mortise case needs a mortise cylinder instead, such as the Detex MC65 6-pin, 1-1/8 inch on the Schlage C keyway.
4) What is the closest key-in-lever replacement cylinder to a Corbin Russwin 2000-052 if the lock body is a Falcon rather than a Corbin Russwin?
The Corbin Russwin 2000-052 is a Conventional Key-In-Lever cylinder built for UT5200 and CK4200 Series hardware, so it belongs in Corbin Russwin lever bodies. For a Falcon lever, the equivalent part is the Falcon A23161-05 G Key in Lever Cylinder for the RU/T Series, a 6-pin G keyway cylinder supplied keyed different with 2 cut keys. Both are key-in-lever cylinders and both ship with two keys; the difference is the lock body each one is cut to seat in, which is why the cylinder follows the lock brand rather than the other way around.
5) Is there a universal key-in-lever cylinder that covers more than one lock brand instead of a brand-specific one?
Yes. The Kaba Ilco 1539 Series is a Key-In-Knob / Lever Universal Cylinder, and Kaba Ilco also builds brand-targeted versions such as the 1579 Series Knob and Lever Cylinder for Sargent and the 1599 Key-in-Knob Replacement Cylinder. The Corbin Russwin 2000-052 takes the opposite approach: it is a Conventional Key-In-Lever cylinder cut specifically for UT5200 and CK4200 Series hardware. Pick the Corbin Russwin part when you are keeping the opening within an existing Corbin Russwin master key system, and look at the Ilco universal route when a mixed building of knob and lever bodies has to be serviced from one shelf part.
6) The opening is an exit device with a rim cylinder, not a lever - what should be ordered instead of a 2000-052?
A rim cylinder, not a key-in-lever cylinder. The 2000-052 is a Conventional Key-In-Lever cylinder for UT5200 and CK4200 Series lever hardware and will not seat in a rim application. For rim prep, the Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and 2 keys, and the 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam and 2 keys. Confirm which cam orientation the device calls for before ordering, since that is the one difference between those two parts.
7) Can a 2000-052 be used where a mortise cylinder is specified?
No - those are two different cylinder formats. The 2000-052 is a Conventional Key-In-Lever cylinder that drops into UT5200 and CK4200 Series lever hardware. A mortise prep takes a threaded mortise cylinder such as the Adams Rite 4036 Mortise Cylinder, a Grade 1 five-pin cylinder in the 4036 Series, or the Detex MC65 Mortise Cylinder, a 1-1/8 inch 6-pin commercial cylinder in the Schlage C keyway. Check the housing on the lock body you are servicing: a lever body wants the key-in-lever part, a mortise case wants the mortise part.
8) For a facility standardizing on interchangeable cores so a core can be pulled and rekeyed without removing the lock, is a Corbin Russwin 2000-052 the right part?
The 2000-052 is a Conventional Key-In-Lever cylinder, meaning the cylinder itself is the keyed unit in the lever body. Facilities that want to swap keying at the core instead look at interchangeable core products: the BEST 1CB is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill-resistant patented interchangeable core 7-pin brass 150 Series core, and the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and 2 keys, with the 20-057-C supplied as a full size interchangeable core in the C keyway and 643E Aged Bronze. The conventional route keys into an existing Corbin Russwin master key hierarchy; the core route changes how rekeying is performed in the field.
9) Is a key-in-lever cylinder like the 2000-052 interchangeable with a deadbolt cylinder?
No, and this is the substitution that most often comes back. The 2000-052 is a Conventional Key-In-Lever cylinder for UT5200 and CK4200 Series lever hardware. Deadbolt cylinders are a separate function: the Kaba Ilco 1549 Series is a Key-In-Deadbolt Cylinder, and the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, while the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts. The tailpiece and the drive that turns the bolt differ from what a lever body accepts, so match the cylinder to the lock function on the door.
10) A 7-pin cylinder is needed for a large master key system - does the 2000-052 go that high, or is a different part required?
The Corbin Russwin 2000-052 is offered in both 6 pin and 7 pin, so a deeper master key hierarchy stays within the same part, and it is available across a wide keyway range including the 27, 57, 59, 67, 77 and N series keyways. Among comparable 7-pin options, the BEST 1CDF is a drill resistant patented interchangeable core 7-pin brass 150 Series core. The Corbin Russwin part keeps the keying in a Conventional Key-In-Lever cylinder matched to UT5200 and CK4200 Series hardware, while the BEST part puts the 7 pins into an interchangeable core format.
11) Do I have to order the Corbin Russwin 052 cylinder by hand of door?
No handing to figure out. The 052 is non-handed, so one part covers left and right hand openings, inswing or outswing. What you do have to specify is finish, keyway, and pin count.
12) Should I choose 6-pin or 7-pin on a Corbin Russwin 052 cylinder?
Match whatever your system runs on. The 052 is built both ways. Six pins is the common commercial chamber count; seven gives a larger master keying hierarchy, which is why larger campuses and multi-building portfolios sit on 7-pin. Mixing pin counts inside one system breaks the master keying, so a property manager replacing one cylinder on an existing system copies the count already in the door.
13) Can I rekey a handful of doors by swapping just the cylinder instead of replacing the locks?
On UT5200 and CK4200 Series locks, yes, and that is the usual move. The 052 is the replacement cylinder for those locks, so you change keying by changing the cylinder and leave the lever, chassis, and door prep alone. Order one per door, on the keyway and pin count your system runs, and each arrives with two keys.
14) What is the difference between ordering a 2000-052 and ordering a cylinder core like a BEST 1C5?
A complete cylinder versus a core. The Corbin Russwin 2000-052 is a Conventional Key-In-Lever replacement cylinder for UT5200 and CK4200 Series hardware, supplied with 2 keys, in 606 Satin Brass or 626 Satin Chrome. The BEST 1C5 is a standard 5-pin cylinder core from the Standard and Premium Cores line - a core that goes into a housing already in the door. If the lever body needs the whole keyed cylinder replaced, the Corbin Russwin part is what fits; if only the keying element is being changed in an existing core housing, a core is the part to order.
15) Does the 2000-052 work on an aluminum storefront door with a narrow stile deadlock?
Narrow stile storefront deadlocks use their own cylinder hardware, not a key-in-lever cylinder. The 2000-052 is a Conventional Key-In-Lever cylinder for UT5200 and CK4200 Series lever hardware. For an Adams Rite MS1847 deadlock or deadlatch, the matching parts are the Adams Rite 4024 cylinder pull with trim plate mounting and the 4025 five pin tumbler cylinder pull with through-screws; for the Adams Rite 5017 wood door deadlock or deadlatch it is the 4026 five pin tumbler cylinder pull. Identify the deadlock model in the stile first, because the cylinder pull is selected from it.
16) Is the 2000-052 the right cylinder for a residential handleset or an Emtek lock?
No - the 2000-052 is a commercial Conventional Key-In-Lever cylinder for UT5200 and CK4200 Series hardware. Handleset and residential-style openings are served by different parts: the Emtek CY4 Cylinder is sold as a single unit for Emtek hardware, the Medeco 1065244 is a 5-pin rim lazy motion rim type cylinder with an Emtek tailpiece, and the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and for an Emtek handleset or deadbolt outside cylinder. The tailpiece is what decides it, so identify the hardware the cylinder is going into before ordering.
17) Does handing need to be confirmed when choosing between a 2000-052 and another key-in-lever cylinder?
Not for the Corbin Russwin 2000-052 - it is non-handed, so the same cylinder serves left and right hand openings and one part number covers both sides of a corridor. The comparable key-in-lever options are selected the same way, by lock body rather than by hand: the Falcon A23161-05 G is specified to the RU/T Series with a 6-pin G keyway, and the Kaba Ilco 1539 Series is a universal key-in-knob and lever cylinder. What does need confirming on any of them is the keyway and pin count, since that is what ties the cylinder into the building's key system.
18) Does a Corbin Russwin 052 cylinder come with keys, or do I order those separately?
Two keys ship with it. For a straight swap that is enough to test and hand off the opening. If you need more than two per door, or you want them keyed alike across a run of doors, that is a keying instruction at order time, not something the standard pack covers.
19) Which finish of the Corbin Russwin 052 matches the lever trim already on my doors?
Two finishes are made: 606 Satin Brass and 626 Satin Chrome. 626 is the one that lines up with the satin chrome and brushed nickel lever trim most commercial openings are specified in; 606 is for brass-finished hardware. The cylinder face is the visible part, so pick the finish of the lever it is going into.
20) Is the Corbin Russwin 2000-052 rated for commercial traffic or is it a residential part?
Commercial. It is a 2000 Series cylinder for commercial door hardware, used in offices, schools, healthcare, retail, warehouse, multi-tenant residential, and government buildings. For residential handleset and deadbolt cylinders you would be looking at something like the Medeco 1075127 5-pin rim type lazy motion cylinder or the Emtek CY4 instead.
21) What should be ordered for a door that needs the trim to look keyed but not actually lock?
A dummy cylinder rather than a functioning one. The BEST 12E Series Dummy Rim Cylinder has a 1-5/32 inch diameter and fills a rim prep without operating anything. The Corbin Russwin 2000-052 is the opposite case: a Conventional Key-In-Lever cylinder supplied with 2 keys that becomes an operating part of a master key system in UT5200 and CK4200 Series hardware. Use the dummy where only the prep needs to be covered and the keyed cylinder where the opening is actually being secured.
