Schlage C503-0116 – Frequently Asked Questions
1) Will the Schlage C503-116 cap pin work with an interchangeable core cylinder?
No. The C503-116 cap pin is specified for non-IC (conventional) Schlage cylinders only. If you are servicing a Schlage interchangeable core (Everest or classic IC) housing, this is the wrong retaining part and you need the IC-specific component instead.
2) I need pins and springs to rekey a Schlage cylinder. Is the C503-116 what I want?
No. The C503-116 is the cap pin, the retainer for the cylinder cap, not a top pin, bottom pin, or spring. For rekeying you need Schlage bottom pins and springs in the correct sizes; order the cap pin only if the cap retainer itself is missing or damaged.
3) What does the cap pin in a Schlage conventional cylinder actually do?
It is the small retaining pin that holds the cylinder cap in place over the pin chamber stack, keeping the springs and top pins captive in the cylinder body. When you pin up or rekey a conventional Schlage cylinder and the cap comes off or the original pin is lost, the C503-116 is the replacement that puts it back together.
4) Is the Schlage C503-116 cap pin OK for commercial lock service work?
Yes, it is classified as a commercial door hardware part and is a genuine Schlage replacement component, so it is what a locksmith or facilities shop uses when rebuilding Schlage conventional cylinders across an institutional or multi-family keying system.
5) Does the cap pin come in a finish to match my cylinder?
The C503-116 is a single model with no finish options. Note that many Schlage service parts are finish specific, so if you are also ordering visible parts such as cylinder collars or plates, specify the finish on those; the cap pin is an internal component and is not finish selected.
