Ready to Ship Ignition Lock Cylinder for 81900-2GF00
An ignition lock cylinder (also called an ignition cylinder, key cylinder, or ignition barrel) is the core mechanical component in a vehicle’s ignition system that receives and validates the physical key. It is typically mounted on the steering column or dashboard, acting as the primary mechanical interface between the driver and the car’s electrical and starting systems.
Core Components

- Tumblers/Pins: Spring-loaded metal pins (wafer or pin-tumbler design) that match the key’s unique cuts.
