Kaba Ilco 15985-AA-26D-KA – Frequently Asked Questions

1) Will the Kaba Ilco 1599 cylinder work in my Schlage knob lockset?
Yes. The Ilco 1599 is a replacement key-in-knob, lever, and deadbolt cylinder built for universal knob and lever locksets, including Schlage, plus Arrow and Schlage deadbolts. Order it in the Schlage keyway you already key to: SC Schlage C, SE Schlage E, SF Schlage F, SX Schlage, or EA/EB Schlage Everest. If your building is keyed on Schlage C, the SC keyway 1599 keys into the existing system.
2) Do I have to order a tailpiece separately for the Ilco 1599 cylinder?
No, the tailpieces come with it. Each 1599 cylinder ships with six: three rigid tailpieces in different lengths, one lazy tailpiece for a single deadbolt, and two lazy tailpieces in different lengths for a double cylinder deadbolt. That covers a knob or lever lockset and both deadbolt configurations out of one box, so you pick the right one at the door instead of ordering again.
3) Can I get Ilco 1599 cylinders keyed alike across a building?
Keyed alike is an ordering option on the 1599, alongside keyed different. For a property manager standardizing several doors, order keyed alike in one keyway and one pin count so every cylinder takes the same key. Mixed openings, some knobs, some deadbolts, all work off that key as long as the keyway and pinning match across the order.
4) Is the Ilco 1599 cylinder a mortise cylinder or a rim cylinder?
Neither. The 1599 is a key-in-knob style cylinder, the kind that drops into a knob or lever lockset or a deadbolt and drives the lock through a tailpiece. It has no threaded barrel like a mortise cylinder and no rim ring and back plate. If you are cylinder-swapping a mortise lock body, you want a threaded mortise cylinder such as the Corbin Russwin 1000 Series (1-1/2 inch, A02 straight cam) or the Detex MC65 in Schlage C. If you are feeding an exit device from the outside, that is a rim cylinder, like the Schlage 20-021 with a vertical tailpiece cam or the 20-022 with a horizontal cam.
5) What should I order instead of an Ilco 1599 if the lock takes a mortise cylinder?
The 1599 is a knob, lever and deadbolt cylinder, not a mortise cylinder, so it will not thread into a mortise lock case. For mortise applications the Corbin Russwin 1000 is a Grade 1 mortise cylinder in 1-1/2 inch length with an A02 straight cam, and the Corbin Russwin 1070 is a Grade 1 series 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. The Adams Rite 4036 is a Grade 1 five-pin mortise cylinder with a 1/2 inch minimum door thickness. Cam style is the deciding detail: match the cam to the lock case, the way you match the tailpiece on a key-in-knob cylinder.
6) If our facility is standardizing on interchangeable core, is the Ilco 1599 the right cylinder?
The 1599 is a conventional keyed cylinder ordered by keyway and pinning in 5 pin, 5 pin drilled 6, or 6 pin, keyed alike or keyed different. It is not an interchangeable core product. For an IC program, the BEST 1C series standard 5-pin cylinder core and the BEST Peaks 1CB 150 series interchangeable core cylinder are core-based, and the BEST 1CDF is a drill resistant patented interchangeable core 7-pin brass cylinder in the 150 series. On the Schlage side, the 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and the 20-057-C is a full size interchangeable core in C keyway with a 643E aged bronze finish. IC lets maintenance rekey by pulling cores with a control key rather than repinning; the 1599 is repinned or replaced.
7) Will an Ilco 1599 cylinder work in an Adams Rite MS1847 storefront deadlock?
No. The 1599 is a key-in-knob, lever and deadbolt replacement cylinder with rigid and lazy tailpieces. Adams Rite MS1847 deadlock systems take a cylinder pull: the Adams Rite 4024 mounts with a trim plate and the Adams Rite 4025 is a five pin tumbler cylinder pull with through-screws, both designed for use with the Adams Rite MS1847 deadlock/deadlatch. For a wood door deadlock, the Adams Rite 4026 is a five pin tumbler cylinder pull for the Adams Rite 5017 wood door deadlock/deadlatch.
8) We run Schlage L9000 mortise locks. Does the Ilco 1599 fit them?
No. The Schlage L9000 mortise lock takes a mortise cylinder, and the Corbin Russwin 1080 is a Grade 1 series 1-1/2 inch LFIC mortise cylinder, 6-pin, listed for Schlage L9000 mortise locks with an A01 Schlage L cam. The 1599 is a knob, lever and deadbolt cylinder supplied with rigid and lazy tailpieces, which is a different interface from a mortise cam.
9) What keyways does the Ilco 1599 replacement cylinder come in?
Thirty-one keyways, which is the point of the 1599: it lets you match a cylinder into an existing system instead of rekeying the building. The list spans Arrow AA, Corbin CA/CB/CC/CD and Corbin/Russwin CE, Russwin RA and RB, Dominion DA, Schlage SC/SE/SF/SX and Everest EA/EB, Sargent GA/GB/GC, Segal FA, Kwikset KS, Lockwood LA, Lori UB/UD/UE, Weiser WA and WE, Yale YA and YG, Ilco UA, and composite NA/NB. Note UD Lori 90 is 6-pin only and UE Lori 80 is 5-pin.
10) I have an Emtek handleset and deadbolt. Will the Ilco 1599 cylinder fit it?
The 1599 covers universal knob and lever locksets plus Arrow and Schlage deadbolts, and Emtek is not among the applications named for it. For Emtek hardware, use a cylinder built for it: the Medeco 1065140 is a 5-pin retrofit for the Emtek handleset and deadbolt outside cylinder, and the Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece. The Emtek CY4 cylinder is the factory part.
11) I have a Kwikset deadbolt but the rest of the building is on a different key. What are my options with the Ilco 1599?
The 1599 comes in KS Kwikset keyway, so you can replace the cylinder and stay on the existing Kwikset keys. If instead you want the Kwikset deadbolt brought onto the building's key, order the 1599 in the building's keyway (Schlage SC, Sargent, Corbin/Russwin, whichever it runs on) keyed alike with the other cylinders, since the 1599 is designed to key into universal knob, lever, and deadbolt hardware. A Medeco 1012040 6-pin lazy motion rim cylinder is the alternative built specifically for Kwikset single cylinder deadbolts.
12) What do I need to specify when ordering an Ilco 1599 cylinder?
Four things settle the order on the 1599: keyway (31 to choose from, matched to your existing keys), pinning (5 pin, 6 pin, or 5 pin drilled 6), keying (keyed alike if several cylinders share a key, keyed different if not), and finish (satin brass 04 or satin chrome 26D). Tailpieces are not a separate line, six ship in the box.
13) For a handleset with a single deadbolt, what are my cylinder choices besides the Ilco 1599?
The 1599 ships with 6 tailpieces, one of which is a lazy tailpiece for a single deadbolt and two more lazy tailpieces in different lengths for a double deadbolt, so one cylinder covers both arrangements. The Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts. All three use lazy motion; the difference is that the 1599 is ordered in your choice of 31 keyways while the Medeco parts are fixed to their own platform.
14) What is the difference between the Ilco 1599 and a Medeco retrofit cylinder for an Arrow or Emtek handleset?
Both replace the cylinder in an existing lockset. The 1599 covers a broad range with 31 keyways, including AA Arrow, and comes with 6 tailpieces so one part number adapts to several locksets. The Medeco 1065140 is a 5-pin retrofit cylinder built for the Arrow JL interconnected lock and the Emtek handleset and deadbolt outside cylinder, and the Medeco 1065244 is a 5-pin rim lazy motion cylinder supplied with an Emtek tailpiece. The Medeco parts are single-application retrofits on a patented platform; the 1599 is a multi-keyway program you key into whatever system the building already runs.
15) I need to match an existing Schlage C keyway system across a building. Ilco 1599 or something else?
The 1599 is offered in SC Schlage C along with SE Schlage E, SF Schlage F, SX Schlage and both Schlage Everest keyways EA and EB, in satin brass and satin chrome, keyed alike or keyed different, so one series can cover knobs, levers and deadbolts on a single key system. If the opening in question is a mortise application rather than a knob or lever, the Detex MC65 is a mortise cylinder in Schlage C keyway, 1-1/8 inch, 6-pin. Match the cylinder type to the lock first, then the keyway.
16) Is the Ilco 1599 an equivalent to a Falcon key-in-lever cylinder?
They serve the same role. The Falcon A23161-05 G is a key in lever cylinder for the RU/T series, 6-pin, G keyway, keyed different, supplied with 2 cut keys. The 1599 covers key-in-lever applications as well and is ordered in 5 pin, 5 pin drilled 6 or 6 pin, keyed alike or keyed different, across 31 keyways including WA Weiser E Falcon. The Falcon part is a single fixed configuration; the 1599 is configured at order time to the keyway and pinning of the system you are matching.
17) What looks like a cylinder substitute but will not actually key a door?
The BEST 12E series dummy rim cylinder, 1-5/32 inch diameter, is a dummy: it fills the cylinder opening and is not a keyed function. The Adams Rite 4024, 4025 and 4026 are cylinder pulls, which combine a pull with a cylinder for specific Adams Rite deadlocks rather than replacing a cylinder in a knob or lever. The Ilco 1599 is a keyed replacement cylinder for knob, lever and deadbolt locksets, ordered by keyway, pinning and keying.
18) What finishes does the Ilco 1599 cylinder come in, and will it match my existing hardware?
Two finishes: satin brass (04) and satin chrome (26D). Satin chrome 26D is the standard commercial finish and will read as a match against the satin chrome and brushed stainless lever and knob trim on most commercial openings. Satin brass suits older brass-trimmed doors. Since only the cylinder face shows through the knob or deadbolt collar, pick whichever is closer to the surrounding trim.
19) Is the Ilco 1599 cylinder suitable for a commercial building or is it residential grade?
Commercial. The 1599 is a commercial-duty replacement cylinder, which is why it carries keyways for the systems commercial buildings actually run on, Sargent LA and RA/RC, Corbin/Russwin, Schlage Everest, Yale 8, and Lockwood. It also offers Kwikset KS and Weiser keyways, so a mixed portfolio with residential units and commercial common doors can be handled from the same part.
