Kaba Ilco 26026-SE-26D-0B – Frequently Asked Questions

1) What does 0-bitted mean on an interchangeable core, and can I use it out of the box?
0-bitted means the core ships uncombinated, with no cuts assigned. A locksmith pins it to whatever key you already run, so the core joins your existing Schlage C keyway system rather than adding another key to the ring. That also means it is not ready to key straight from the box: it needs pinning to your bitting before it will operate. Two keys are supplied with it.
2) Can I put an interchangeable core into locks that currently have conventional Schlage cylinders?
Not directly. The core needs a housing or lock body prepped for a full size interchangeable core; a conventional mortise or rim cylinder body will not accept it. What does carry over is the keying: because the 26026-0B uses a shared keyway family, it can be pinned into an existing conventional Schlage C system and run on the same key. If you need the housing too, the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam that accepts a full size core.
3) What is the difference between the Kaba Ilco 26026-0B and the Schlage 20-057-C interchangeable core?
Both are full size interchangeable cores cut to the Schlage C keyway. The Kaba Ilco 26026-0B is a 6-pin brass FSIC core supplied 0-bitted, meaning it ships uncombinated for a locksmith to pin to an existing system, and it comes in 626 satin chrome with 2 keys. The Schlage 20-057-C is Schlage's own C keyway full size interchangeable core cylinder in 643E aged bronze. Choose on keying program and finish: 0-bitted brass core for a shop that pins its own, factory Schlage core in aged bronze where the finish has to match adjacent Schlage trim.
4) Will a BEST interchangeable core work in place of the Kaba Ilco 26026-0B?
They are different core systems and are not drop-in for each other. The Kaba Ilco 26026-0B is a 6-pin full size interchangeable core on the Schlage C keyway, built to the industry standard 1/2 inch plug diameter so it integrates with an existing conventional Schlage C keyway system. The BEST 1C is a standard 5-pin cylinder core and the BEST Peaks 1CB is a 150 Series interchangeable core; those run on BEST's own core format and keyway family. A door already carrying BEST cores takes a BEST core such as the 1C or 1CB, and a Schlage C keyway house takes the 26026-0B.
5) I need a rim cylinder for an exit device, not a core. What takes a Schlage C keyway core?
The Kaba Ilco 26026-0B is the core alone, so it needs a housing to land in. For a rim application the Schlage 20-057 is a 6-pin FSIC rim cylinder with a convertible tailpiece cam and 2 keys, and it accepts a full size interchangeable core rather than being a fixed cylinder. That pairing puts the 26026-0B core into an exit device rim prep. If the opening does not need interchangeable core at all, the Schlage 20-021 and 20-022 are fixed 6-pin rim cylinders with 2 keys, the 20-021 with a vertical tailpiece cam and the 20-022 with a horizontal one.
6) My mortise lock needs a Schlage C keyway cylinder. Is the Kaba Ilco 26026-0B the right part?
No. The 26026-0B is a full size interchangeable core, which drops into a housing built to accept a core, not into a mortise lock body directly. For a mortise prep, the Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder on the Schlage C keyway, so it holds the same key system without a core housing. If the opening does need interchangeable core in a mortise lock, the Corbin Russwin 1080 is a Grade 1 Series 1-1/2 inch large format interchangeable core mortise cylinder, 6-pin, for Schlage L9000 mortise locks with an A01 cam.
7) I manage a building and keep having to rekey units. Is an interchangeable core worth it over a standard cylinder?
That is exactly the case an FSIC core is built for. Rekeying a conventional cylinder means pulling the lock apart or sending the cylinder out; with an interchangeable core you turn a control key, pull the core, drop in another, and the door is back in service in seconds. Buying 0-bitted cores like the 26026-0B lets you stock blanks and have them pinned as turnover happens. The tradeoff is that every door has to be running an FSIC-prepped housing first.
8) I need a Schlage C keyway core already keyed, not 0-bitted. What else is there?
If you would rather not pin it yourself, the Schlage 20-057-C is a full size interchangeable core cylinder on the C keyway, finished in 643E aged bronze. For a mortise application on the C keyway rather than a core, the Detex MC65 is a 1-1/8 inch 6-pin commercial mortise cylinder cut to Schlage C. The 26026-0B itself comes 0-bitted, so plan on a locksmith combinating it.
9) Do I get a control key with the 26026-0B core to pull it out of the housing?
Two keys ship with the core. Because it arrives 0-bitted, the control function is set when the core is pinned, so tell your locksmith whether the control should match the control key already in use across the building. Keeping one control on the whole system is what makes swapping cores a one-key job instead of a key ring.
10) What is a higher security alternative to a standard 6-pin interchangeable core?
The BEST 1CDF is a drill resistant patented interchangeable core in brass, 7-pin, from the 150 Series. Against it the Kaba Ilco 26026-0B is a 6-pin brass full size interchangeable core on the Schlage C keyway supplied 0-bitted. The 1CDF adds a seventh pin chamber, drill resistance and patented key control, and it runs on the BEST core format; the 26026-0B stays inside a Schlage C keyway program and can be pinned into an existing conventional system. Facilities that want restricted key control across a building go to the patented core; sites standardized on Schlage C stay with the 26026-0B.
11) What should I order for a conventional mortise cylinder if I do not want interchangeable core at all?
Conventional mortise cylinders are fixed, so rekeying means pulling and repinning the cylinder rather than swapping a core, which is the tradeoff against a core like the Kaba Ilco 26026-0B that is designed for quick rekeying. The Corbin Russwin 1000 is a Grade 1 Series mortise cylinder, 1-1/2 inch, 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. Match the cam to the lock body and the length to the door and trim thickness.
12) Is a cylinder pull the same thing as an interchangeable core?
No, and they solve different problems on the opening. The Kaba Ilco 26026-0B is the keyed core itself, a 6-pin full size interchangeable core on the Schlage C keyway that carries the key cuts and swaps out for rekeying. An Adams Rite cylinder pull is the door pull with a cylinder in it: the 4025 is a five pin tumbler cylinder pull with through-screws for the MS1847 deadlock, the 4024 mounts with a trim plate for the same MS1847 deadlock system, and the 4026 is a five pin tumbler cylinder pull for wood door applications with the Adams Rite 5017 wood door deadlock. Those are chosen by the lock body and door material they serve, not by keyway system.
13) I need a keyed cylinder for an aluminum storefront deadlock, not a core. What do I use?
The Kaba Ilco 26026-0B is a full size interchangeable core and needs a core-accepting housing, which a storefront deadlock prep generally is not. The Adams Rite 4036 is a Grade 1 mortise cylinder with five-pin security in the 4036 Series, with a 1/2 inch minimum door thickness, which is the cylinder shape that suits narrow stile aluminum work. Confirm the cam and cylinder length against the deadlock body before ordering.
14) I need a keyed cylinder for a residential handleset or deadbolt. Does the Kaba Ilco 26026-0B fit?
The 26026-0B is a commercial full size interchangeable core, so it is aimed at commercial core-accepting hardware rather than residential handlesets. For handleset and deadbolt retrofits, the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, 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 Emtek handleset and deadbolt outside cylinder. Pick by the lock brand being retrofitted.
15) Does an interchangeable core have a handing, and does it matter which way the door swings?
No handing on this one. The Kaba Ilco 26026-0B core is non-handed, so the same part works on left and right hand doors, in and swing. Handing is decided by the lock body it goes into, not the core.
16) What finish does the Kaba Ilco 26026-0B core come in, and will it match my other hardware?
Satin chrome, 626, which is the standard commercial finish on most lever sets, exit devices and mortise locks, so it blends with typical office and institutional openings. That is the only finish offered on this core. If your doors are on a bronze scheme, the Schlage 20-057-C FSIC cylinder is a C keyway option in 643E aged bronze.
17) Is the Ilco 26026-0B core suitable for a commercial building or is it a residential part?
Commercial. The 26026-0B is a brass 6-pin full size interchangeable core intended for commercial door hardware, sold as a replacement part for locks already running an FSIC housing. Brass is the standard core material and it pins with conventional bottom pins and top pins on the C keyway.
18) The opening does not need to be keyed, it just needs a cylinder to fill the hole. What is the alternative?
A dummy cylinder fills the prep without a key system. The BEST 12E Series dummy rim cylinder has a 1-5/32 inch diameter and is the part for a rim prep that needs to look complete but not lock. The Kaba Ilco 26026-0B is the opposite case: a keyed 6-pin full size interchangeable core supplied with 2 keys and designed to be swapped for rekeying.
