Schlage C603-827 – Frequently Asked Questions

1) What is the Schlage C603-827 and where does it go in an FSIC core?
The C603-827 is a genuine Schlage core cap pin for Full Size Interchangeable Core cylinders. It is the small pin that retains the cap on an FSIC core, so it is a service part consumed when a locksmith opens a core to repin it and rebuilds it. It is not a top pin, bottom pin or master wafer, and it does not change a keying combination on its own. Schlage lists it as a commercial replacement part for FSIC rekeying.
2) Can I buy just a few Schlage C603-827 core cap pins, or is there a minimum?
They only sell in multiples of 100. That is a hard ordering rule on the C603-827, not a suggested pack, so a shop that needs a handful still orders a hundred. For a maintenance department or a locksmith running a rekey program that is usually fine, since cap pins get lost and deformed during core rebuilds and are worth carrying on the truck in bulk.
3) Will the Schlage C603-827 cap pin work in a small format interchangeable core?
No. The C603-827 is built for Schlage Full Size Interchangeable Core cylinders. SFIC cores, the Best-style figure-eight format, are a different housing entirely and take their own retainer parts. If the cores on your building are the small figure-eight shape, this is the wrong part.
4) We standardize our whole campus on Schlage FSIC. Is the C603-827 the right consumable to stock for that?
Yes, for cap retention on Schlage FSIC cores. Schlage sells the C603-827 as the commercial rekey part for that platform, and the multiples-of-100 buy is aimed at exactly this kind of program: a stocking shelf for offices, schools, healthcare, government and multi-tenant residential portfolios where cores get pulled and recombinated on a schedule. It does not replace the core itself, only the cap pin inside it.
5) Does buying the Schlage C603-827 mean I have to replace the whole lock or cylinder?
No, that is the point of it. The cap pin is a component-level replacement that keeps an existing Schlage FSIC installation serviceable without pulling the lockset or buying a new core. You repin the core, refit the cap, set a fresh cap pin, and the opening goes back into service on the same hardware.
6) Is the Schlage C603-827 an aftermarket pin or a factory Schlage part?
Factory. The C603-827 is sourced from Schlage and made to their commercial spec, which matters on interchangeable core work because a cap pin that sits a thousandth off can bind the cap or let it walk loose. If you are maintaining an existing Schlage FSIC keying system, this keeps the rebuilt cores to the same standard as the original install.
