Medeco CP-030018 – Frequently Asked Questions

1) What exactly is the Medeco CP-030018 and what does the sidebar spring do inside the cylinder?
The CP-030018 is Medeco's genuine sidebar spring, a small internal component that loads the sidebar so it can engage and release properly as the pins rotate to position. It is a replacement part from Medeco's Tools, Parts and Accessories program, used when rebuilding or servicing compatible Medeco mechanical lock cylinders. It is not a pin, a cam, or a cylinder assembly, just the spring.
2) Is the Medeco CP-030018 sidebar spring sold individually or only in bulk?
It comes as a 100-pack, one part number per pack. That quantity suits a locksmith building service kits or a facility running a cylinder rebuild program rather than someone repairing a single lock. If you only need one spring, you are still buying the full hundred.
3) Will the CP-030018 work in any Medeco cylinder?
It is the correct OEM sidebar spring for compatible Medeco mechanical lock cylinders, and Medeco publishes it under that one part number for those cylinders. Match the part number to the cylinder generation you are servicing before you pull it apart, because the spring is specified by Medeco per cylinder platform, not universally across the whole line.
4) Can a Corbin Russwin swivel spindle pin and set screw be used in place of a Medeco CP-030018 sidebar spring?
No. The Medeco CP-030018 is a sidebar spring, an internal cylinder component that restores sidebar engagement in compatible Medeco mechanical lock cylinders, and it is supplied as a genuine OEM replacement part in a 100-pack. The Corbin Russwin swivel spindle pin x set screw is a spindle retention part for a lock's trim and spindle assembly, listed for 1-3/4 inch door thickness. They serve entirely different mechanisms, so neither one substitutes for the other in a cylinder rebuild.
5) Can I substitute a generic sidebar spring instead of the Medeco part?
No. The sidebar spring sets the load that determines whether the sidebar drops into the gates reliably, and Medeco specifies the CP-030018 as the OEM component for that job. A substitute with different rate or free length changes sidebar behavior and can leave a high-security cylinder binding or, worse, operating when it should not.
6) I need a spindle part, not a sidebar spring. What else is there in this category?
If you are after a swivel spindle rather than a cylinder spring, the Corbin Russwin Swivel Spindle Pin x Set Screw covers that, and it is listed for 1-3/4 inch doors. It does nothing for a Medeco cylinder rebuild, though; the CP-030018 is a cylinder internal, while the Corbin Russwin part belongs to the lock chassis and spindle side of a door.
7) I need a small lock part but my door is 1-3/4 inch thick - does that matter when choosing between the Medeco CP-030018 and the Corbin Russwin 499F838?
Door thickness is a selection factor for the Corbin Russwin swivel spindle pin x set screw, which is listed for 1-3/4 inch doors because a spindle part has to span the door. The Medeco CP-030018 sidebar spring sits inside the lock cylinder, so it is selected by cylinder compatibility rather than by door thickness. If your task is fitting trim and spindle hardware to a 1-3/4 inch door, the Corbin Russwin part is the one keyed to that dimension; if you are rebuilding a compatible Medeco cylinder, the CP-030018 is the genuine OEM spring for that job.
8) Is this Medeco spring rated for commercial lock service work?
Yes, the CP-030018 is classed as a commercial-grade component and is aimed at professional locksmith, institutional, healthcare, education, and government lock maintenance work rather than residential DIY repair.
