Kwikset 3103 Bottom Pins Size 3 100 Pack Rekey Kit

Product Description

The KWIKSET 3103 is a pack of 100 size 3 bottom pins designed for use in Kwikset pin tumbler lock cylinders. Bottom pins are the lowest-level components in a pin stack, sitting directly above the key cuts and working in tandem with driver pins and springs to establish the shear line when the correct key is inserted. This pack supports locksmiths and security professionals performing high-volume rekeying work, allowing them to restock a single pin size without purchasing a full assorted kit. Each pin measures 0.75 inches in length and 0.25 inches in height, with a pack width of 3 inches.

Size 3 bottom pins are a commonly consumed pin size in residential rekeying operations. This pack suits locksmiths, property managers, and security technicians who rekey Kwikset pin tumbler cylinders at scale, such as during tenant turnover, lock standardization projects, or service call restocking. The 100-count quantity supports sustained workflow without frequent reorder interruptions.

Installation Notes

Bottom pin replacement and rekeying work should be performed by a licensed locksmith or qualified security professional using a rekeying kit and follower tool. Remove the cylinder from the door hardware before disassembling the pin stack to prevent loss of springs and driver pins. Work on a clean, flat surface and keep pin sizes organized to avoid mixing during reassembly. Verify the new key operates the cylinder smoothly through a full rotation before reinstalling the hardware.
