Schlage 33-236 C135 626 – Frequently Asked Questions

1) Will the Schlage 33-236 plug work in my Everest FSIC cores, or only Classic Schlage C keyway cylinders?
The 33-236 is built to the Schlage Everest Modular standard and is intended for Everest Modular full size interchangeable core cylinders using the C keyway. It is an Everest Modular component, not a Classic-family plug, so match it to Everest Modular FSIC hardware when you order.
2) Which keyway sections can I get on the Schlage 33-236 cylinder plug?
Three C-family Everest sections are offered: C123, C135 and C145. The keying section has to match the keys already cut for the building, so pull the section off your existing key bitting or your key control records before ordering.
3) Is the Schlage 33-236 a complete lock cylinder or just the plug?
Plug only. It is the rotating cylinder plug that carries the bottom pins and the keyway, supplied as a replacement component for an existing Everest Modular FSIC cylinder. You still need the core shell, springs, top pins and bottom pins to build a working core.
4) Is this a 6-pin plug, and can I use it in a 5-pin system?
It is drilled as a 6-pin plug. A 6-pin plug belongs in a 6-pin core and takes 6-pin keys; if your facility is keyed 5-pin throughout, mixing a 6-pin plug in means the existing 5-pin keys will not operate it. Standardize the pin count across the master key system before you swap.
5) What is the difference between the Schlage 33-236 cylinder plug and the Corbin Russwin 253K66 rim cylinder plug?
Both are cylinder plugs, but they belong to different manufacturers' cylinder systems. The Schlage 33-236 is an Everest Modular 6-pin full size interchangeable core (FSIC) plug supplied in the C keyway family, with C135, C123 and C145 keyway options. The Corbin Russwin 253K66 is a 3000 rim cylinder plug, so it is built for a Corbin Russwin rim cylinder housing rather than a Schlage FSIC core. A plug is keyway- and platform-specific, so the two are not interchangeable in each other's cylinders.
6) What finishes does the Schlage 33-236 plug come in, and does the finish matter if it is inside the lock?
Two finishes: 626 satin chrome and 606 satin brass. The plug face is visible at the keyway, so most specifiers match it to the trim on the door. 626 pairs with chrome and brushed nickel hardware, 606 with brass. Satin chrome is offered with the C123, C135 and C145 sections; satin brass is offered with C145.
7) I manage a campus on a master key system. Why buy plugs instead of whole cores?
Buying plugs lets a locksmith rebuild existing cores to new change keys instead of replacing the whole core, which is the cheaper route when you are rotating keying on a large FSIC installation. The 33-236 is a genuine Schlage Everest Modular plug, so it holds manufacturer tolerances inside cores already in service. It suits key control programs where cores get re-pinned rather than scrapped.
8) I need a mortise or rim cylinder plug, not a Schlage FSIC one. What are my options?
For Corbin Russwin hardware the plug-only parts are different pieces entirely: the 121K11-D2 and 121K11-L4 are 1000 Series mortise cylinder plugs, and the 253K66 is a 3000 Series rim cylinder plug. There is also a 219F88-8 cylinder plug retainer for Corbin Russwin cylinders. None of those interchange with a Schlage Everest Modular FSIC core, so pick by the cylinder housing you actually have in the door.
9) Can a Schlage 33-236 plug be keyed into an existing Everest C keyway master key system?
Yes, provided the section matches. Because the plug is manufactured to the Schlage Everest C keyway specification, a locksmith can pin it to your existing change key and master combination as long as the section you order (C123, C135 or C145) is the section your system was set up on.
10) Is the Corbin Russwin 219F88-8 an alternative to the Schlage 33-236 plug?
No. The 219F88-8 is a Grade 1 cylinder plug retainer, meaning it is the retaining component that holds a plug in place rather than the keyed plug itself. The Schlage 33-236 is the plug, a 6-pin Everest Modular FSIC component that carries the pin stack and keyway. If you are re-keying and need the keyed element, the 33-236 is the plug; the 219F88-8 is Corbin Russwin retaining hardware.
11) For standardizing a building on one key system, how do the Schlage 33-236 and Corbin Russwin 121K11 plugs compare?
They commit you to different key systems. The Schlage 33-236 is a commercial Everest Modular 6-pin FSIC plug ordered by C keyway (C135, C123 or C145) and in 626 satin chrome or 606 satin brass, and it suits facilities running master key or key control programs on Schlage interchangeable cores. The Corbin Russwin 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs, keyed to Corbin Russwin D2 and L4 designations for mortise cylinders. Standardize on whichever platform the existing cylinders in the building already use.
