Kaba Ilco 15395-AA-26D-KA – Frequently Asked Questions

1) Will an Ilco 1539 cylinder work in my Schlage key-in-knob lockset?
Yes, the Ilco 1539 universal cylinder is made for key-in-knob and key-in-lever locksets and is available in Schlage keyways: SC (Schlage C), SE (Schlage E), SF (Schlage F), SX (Schlage), plus EA and EB for Schlage Everest. Order the keyway that matches the keys already in use on the building so the new cylinder runs on the existing key system. Three rigid tailpieces come with the cylinder so it can be adapted to different lock bodies.
2) What keyways can I get the Ilco 1539 cylinder in?
31 keyways, covering most of what you will find on a commercial property: Arrow (AA), Corbin 60/67/77 and Corbin/Russwin (CA, CB, CC, CD, CE), Dominion 1054F (DA), Schlage Everest (EA, EB), Segal 9 (FA), Sargent LA, LA-LC and RA-RC (GA, GB, GC), Kwikset (KS), Lockwood (LA), two composite keyways (NA, NB), Russwin and Russwin D1 (RA, RB), Schlage C, E, F and SX, Ilco (UA), Lori L100, Lori 90 6-pin and Lori 80 5-pin (UB, UD, UE), Weiser E Falcon (WA), Weiser (WE), and Yale 8 and Yale (YA, YG). Match the keyway to the keys your tenants already carry.
3) Can I get Ilco 1539 cylinders keyed alike across a building?
Keyed alike and keyed different are both orderable on the 1539 cylinder. Keyed alike puts one key in every cylinder in the order, which is what you want when you are standardizing a run of unit doors or a common-area group. Keyed different gives each cylinder its own key. Whichever you pick, keep the keyway consistent across the order so the cylinders live on one key system.
4) What tailpieces come with the Ilco 1539 cylinder, and do I need to order extra?
Three rigid tailpieces ship with each 1539 cylinder, and two more (BA and BB) are included for Sargent keyways. That is what makes it a universal cylinder: one part number covers a range of knob, lever and deadbolt bodies because you fit the tailpiece that matches the lock instead of buying a body-specific cylinder. Nothing extra to add for the tailpiece itself.
5) I have Best interchangeable core locks. Can I use an Ilco 1539 cylinder in them?
No. Interchangeable core housings take a figure-eight core, not a conventional key-in-knob cylinder, so the 1539 will not go in. For small format IC you want a core such as the BEST 1C Series standard 5-pin core, the BEST Peaks 1CB 150 Series core, or the drill-resistant BEST 1CDF 7-pin. If the housing is full size interchangeable core on an exit device, the Schlage 20-057 FSIC rim cylinder with convertible tailpiece cam is the corresponding part.
6) Can I replace a worn cylinder without replacing the whole lockset?
That is exactly what the 1539 is for. It is a replacement cylinder, so on a knob or lever whose lock body and trim are still sound you swap the cylinder alone and leave the lockset on the door. Order it in the keyway your building already uses and the existing keys keep working, or order keyed different if the point of the swap is to retire a compromised key.
7) What is the difference between the Kaba Ilco 1539 cylinder and the Corbin Russwin 1070 mortise housing?
They fit two different lock preps. The Kaba Ilco 1539 is a key-in-knob and lever cylinder, the round cylinder that drops into the knob or lever itself, and it is also offered in a deadbolt function. The Corbin Russwin 1070 is a 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam, which threads into a mortise lock case body. If the door has a mortise lock, the 1539 will not seat in it; if the door has a cylindrical knob or lever set, the 1070 has nowhere to thread.
8) I need a key-in-lever cylinder for a Falcon lever set - is the Kaba Ilco 1539 an equivalent to the Falcon A23161-05 G?
They serve the same opening. The Falcon A23161-05 G is a key in lever cylinder in the RU/T series with a 6-pin G keyway, keyed different, supplied with 2 cut keys - a single fixed keyway from one manufacturer. The Kaba Ilco 1539 is a universal key-in-knob and lever cylinder offered across 31 keyways, including Corbin/Russwin, Schlage C, E and F, Sargent LA and RA-RC, Yale 8, Kwikset, Weiser, Arrow and Lockwood, in both 5-pin and 6-pin, and keyed alike or keyed different. Choose the Falcon when the opening is keyed on the Falcon G keyway; choose the 1539 when the cylinder has to land on an existing master key system in a different keyway.
9) What should I use instead of the Kaba Ilco 1539 cylinder on a rim exit device?
A rim exit device takes a rim cylinder, not a key-in-knob cylinder. The Schlage Commercial 20-021 is a 6-pin rim cylinder with a vertical tailpiece cam and 2 keys, and the Schlage Commercial 20-022 is the same 6-pin rim cylinder with a horizontal tailpiece cam - the cam orientation is picked to match the device. The Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece. The Kaba Ilco 1539 is a key-in-knob, lever and deadbolt cylinder and does not mount to a rim device.
10) Can the Kaba Ilco 1539 cylinder be used on an aluminum storefront door with an Adams Rite deadlock?
An Adams Rite MS1847 deadlock system is served by its own cylinder parts: the Adams Rite 4024 cylinder pull mounts with a trim plate and the 4025 is a five pin tumbler cylinder pull with through-screws, both designed for the MS1847 deadlock/deadlatch, while the 4026 five pin tumbler cylinder pull is the wood door version for the Adams Rite 5017 deadlock/deadlatch. For a mortise prep in that hardware the Adams Rite 4036 is a Grade 1 five-pin mortise cylinder with a 1/2 inch minimum door thickness. The Kaba Ilco 1539 is a key-in-knob, lever and deadbolt cylinder for cylindrical and deadbolt preps.
11) Will a Corbin Russwin 1000 mortise cylinder work where a Kaba Ilco 1539 is called out?
Only if the door has a mortise lock. The Corbin Russwin 1000 is a Grade 1 series mortise cylinder, 1-1/2 inch, with an A02 straight cam, and it threads into a mortise case. The Kaba Ilco 1539 is a key-in-knob and lever cylinder, also offered in deadbolt function, and it seats in a cylindrical knob, lever or deadbolt. Note that Corbin 60, Corbin 67, Corbin 77, Corbin, Corbin/Russwin, Russwin and Russwin D1 are all among the 1539 keyways, so a building keyed on a Corbin Russwin system can stay on its key whichever part the prep calls for.
12) Will an Ilco 1539 cylinder work in a deadbolt, or is it only for knobs and levers?
Deadbolt is one of the functions the 1539 covers, along with key-in-knob and key-in-lever. It is the same cylinder across all three; the tailpiece you fit decides which body it drives. That is useful on a unit door with a knob and a separate deadbolt, since one cylinder line and one keyway can serve both.
13) What do I have to specify when ordering an Ilco 1539 cylinder?
Four things: keyway (31 to choose from, matched to your existing keys), pinning (5 or 6 pin, matched to the same system), keying (keyed alike for a standardized group or keyed different), and finish (satin brass 04 or satin chrome 26D). Get the keyway and pin count from a key you already have in hand rather than from the door, since that is what the cylinder has to operate on.
14) Can I get an Ilco 1539 cylinder to work on a Sargent key system?
Yes, three Sargent keyways are available: GA (Sargent LA), GB (Sargent LA-LC) and GC (Sargent RA-RC). Sargent applications also get two extra tailpieces, BA and BB, on top of the three rigid tailpieces that ship with every 1539, so the cylinder can be driven correctly in a Sargent lock body.
15) My building is on a Corbin Russwin key system. Which Ilco 1539 keyway do I order?
The 1539 covers five in that family: CA (Corbin 60), CB (Corbin 67), CC (Corbin 77), CD (Corbin), CE (Corbin/Russwin), plus RA (Russwin) and RB (Russwin D1). They are not interchangeable, so identify the exact keyway stamped on your key or read it off the existing cylinder before ordering. If the opening turns out to be a mortise lock rather than a knob or lever, the Corbin Russwin 1070 Grade 1 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam is the mortise-side part.
16) What is the difference between the Kaba Ilco 1539 cylinder and the Medeco retrofit cylinders for handlesets and deadbolts?
The Medeco parts are cut for specific host locks: the 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and for Emtek handleset and deadbolt outside cylinders, the 1065244 is a 5-pin lazy motion rim type cylinder with an Emtek tailpiece, and the 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts. Each is matched to the lock it replaces. The Kaba Ilco 1539 is a universal key-in-knob, lever and deadbolt cylinder that ships with 3 rigid tailpieces, plus BA and BB tailpieces for Sargent keyways, so the tailpiece is selected at install rather than fixed to one brand of host lock.
17) We rekey our own buildings - is the Kaba Ilco 1539 an alternative to a BEST interchangeable core?
They are two different keying systems. The BEST 1C is a standard 5-pin cylinder core and the BEST Peaks 1CB is a 150 series interchangeable core cylinder; an interchangeable core is pulled with a control key and swapped without taking the lock apart, so a facility that has standardized on cores stays with that family. The BEST 1CDF is a drill resistant patented interchangeable core in 7-pin brass for openings that need a restricted key. The Kaba Ilco 1539 is a conventional key-in-knob, lever and deadbolt cylinder pinned to a chosen keyway, ordered keyed alike or keyed different, in 5-pin or 6-pin. It suits buildings keyed conventionally rather than on a core system.
18) Is the BEST 12E dummy rim cylinder a substitute for a Kaba Ilco 1539 cylinder?
No. The BEST 12E is a dummy rim cylinder with a 1-5/32 inch diameter - a blank that fills the cylinder hole and gives the outside of the door a finished look with no key function behind it. The Kaba Ilco 1539 is a working key-in-knob, lever and deadbolt cylinder, pinned to one of 31 keyways and supplied keyed alike or keyed different. Use the 12E only where the opening is not meant to be keyed.
19) Our facility is moving to interchangeable core - is the Kaba Ilco 1539 or a Schlage FSIC cylinder the right choice?
For a full size interchangeable core program, the Schlage Commercial 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and 2 keys, and the 20-057-C is a full size interchangeable core cylinder on the C keyway in 643E aged bronze. The Corbin Russwin 1080 is a Grade 1 1-1/2 inch LFIC 6-pin mortise cylinder with an A01 cam for Schlage L9000 mortise locks, which is the small format core route in a mortise body. The Kaba Ilco 1539 is a conventional key-in-knob, lever and deadbolt cylinder in Satin Brass or Satin Chrome, pinned to a fixed keyway rather than accepting a removable core.
20) I am replacing the cylinder in an Emtek lock - do I order the Emtek CY4 or a Kaba Ilco 1539?
The Emtek CY4 is the cylinder sold as an Emtek part, sold each. If the Emtek host lock is being kept and the intent is a like-for-like factory cylinder, that is the direct part. Medeco also makes Emtek-specific pieces: the 1065140 is a 5-pin retrofit for Emtek handleset and deadbolt outside cylinders and the 1065244 is a 5-pin lazy motion rim type cylinder with an Emtek tailpiece. The Kaba Ilco 1539 is the choice when the cylinder needs to come out of the factory keyway and onto a building key system, since it covers 31 keyways in 5-pin and 6-pin, keyed alike or keyed different.
21) Is the Ilco 1539 cylinder suitable for commercial doors or is it residential grade?
Commercial. The 1539 is a commercial door hardware cylinder, which is why the keyway list runs to brands like Sargent, Corbin Russwin, Yale and Lockwood rather than just residential keyways. It does carry Kwikset (KS) and Weiser (WE) keyways as well, which is what you use on the residential-keyed doors inside a mixed portfolio.
