Schlage 33-058C 626 – Frequently Asked Questions

1) Will the Schlage 33-058C plug work with my existing Schlage C keyway master key system?
Yes. The 33-058C is factory cut for the Schlage C keyway, so it takes standard C keyway blanks and drops into an existing C keyway master key program. If your building is keyed in a different Schlage keyway (E, EF, F, and so on), this plug is the wrong part.
2) Is the Schlage 33-058C a full core or just the plug?
Plug only. The 33-058C is the cylinder plug that sits inside a Schlage full size interchangeable core, not a complete core and not a lock cylinder. You pin it and install it into your existing FSIC core shell, which is what makes it useful for repairing a core rather than buying a whole new one.
3) Does the 33-058C fit small format interchangeable core (SFIC) locks?
No. This plug is built for Schlage Full Size Interchangeable Core hardware. SFIC cores are a different, smaller format and use their own figure-eight plug, so a 33-058C will not go into one.
4) Is the Corbin Russwin 253K66 a substitute for the Schlage 33-058C cylinder plug?
No. The Schlage 33-058C is a standard 6-pin full size interchangeable core (FSIC) cylinder plug cut for the Schlage C keyway, so it belongs in a Schlage FSIC core and an existing Schlage C master key program. The Corbin Russwin 253K66 is a 3000 rim cylinder plug, a plug for a rim cylinder rather than an FSIC core, and it is keyed to Corbin Russwin keyways. They are not cross-compatible; the choice follows the lock family already on the door.
5) What do I order if the door has a Corbin Russwin mortise cylinder instead of a Schlage interchangeable core?
Use a Corbin Russwin plug for that lock. The 121K11-D2 and 121K11-L4 are Grade 1 1000 Series mortise cylinder plugs, sold as plug only, and they differ from each other by keyway designation (D2 and L4) so you match whichever your existing key system uses. The Schlage 33-058C is the equivalent part on the Schlage side, a 6-pin FSIC plug in the C keyway, and it fits Schlage full size interchangeable cores rather than a Corbin Russwin mortise cylinder.
6) How many pins does the Schlage 33-058C cylinder plug take?
It is a standard 6-pin plug, which is the common commercial Schlage configuration. If your master key system is pinned 5-pin, the chambers still line up on the standard Schlage spacing, but a locksmith pinning this should build it as a 6-pin plug to match the core it goes into.
7) What finishes does the Schlage 33-058C come in, and does the plug finish need to match my lock?
Two: 606 satin brass and 626 satin chrome. The plug face is the visible part of the core in the keyway, so on a building standardized in 626 satin chrome hardware, order 626 so the repaired core does not stand out against the rest of the openings.
8) Can I rekey a Schlage FSIC core by replacing just the plug?
That is exactly what the 33-058C is for. Swapping the plug lets you change the keying or replace a worn or picked plug without pulling and replacing the entire core or the lock body, which is how facility maintenance teams and locksmiths keep a master key program running with minimum parts.
9) Difference between the Corbin Russwin 121K11-D2 and 121K11-L4 mortise cylinder plugs?
Both are Grade 1 1000 Series mortise cylinder plugs supplied as the plug only; the D2 and L4 suffixes call out different keyway designations, so the one you order is set by the key system already in the building. Neither is interchangeable with the Schlage 33-058C, which is a 6-pin FSIC plug in the Schlage C keyway for Schlage interchangeable core systems.
10) Is the Corbin Russwin 219F88-8 the same kind of part as the Schlage 33-058C?
No. The 219F88-8 is a Grade 1 cylinder plug retainer, the small component that holds a plug in place, not the plug itself. The Schlage 33-058C is the plug: the keyed 6-pin barrel for a Schlage full size interchangeable core in the C keyway. If you are rebuilding a Schlage FSIC core, the 33-058C is the piece that carries the key cuts.
11) Is a cylinder plug the same thing as a plug retainer?
No, and buying one for the other is a common mix-up. The Schlage 33-058C is the keyed plug itself, the rotating barrel the key enters. A retainer, like the Corbin Russwin 219F88-8 cylinder plug retainer, is the small hardware piece that holds a plug in its shell. If your plug spins free or falls out, you likely need a retainer, not a new plug.
12) Is the 33-058C suitable for residential locks or commercial only?
It is a commercial part. Schlage lists the 33-058C under commercial mechanical lock hardware, which is where FSIC cores are used: offices, schools, healthcare, government buildings, and multi-tenant properties on a master key program. Residential Schlage knobs and levers generally do not use an interchangeable core at all.
13) I need to match the finish on existing hardware - what finishes does the 33-058C come in versus the Corbin Russwin plugs?
The Schlage 33-058C 6-pin FSIC plug is offered in 606 satin brass and 626 satin chrome, so it can be matched to either brass-tone or chrome-tone Schlage trim. The Corbin Russwin alternatives are ordered by their own designations: 121K11-D2 and 121K11-L4 as 1000 Series mortise cylinder plugs and 253K66 as a 3000 rim cylinder plug.
