Mazda 3 Ignition Lock Cylinder

The Mazda 3 Ignition Lock Cylinder provides drivers with secure and easy access to engine start-up, as well as steering wheel lock-up against theft. The steering column has a lock cylinder where a uniquely cut key is accepted, which will turn the unlocked ignition switch through the OFF, ACC, ON, and START positions that will successively switch battery power to the parts and engine management, and eventually to the starter motor. Once the key is released, the internal wafers of the cylinder fall, the column shaft engages, and an automatic transmission shift interlock prevents the lever from moving while it remains parked. Early automobiles applied basic key slots on the dashboard, but as 1970s laws compelled all manufacturers, including Mazda, to column-mount switch locks, physically barring the steering, this type of lock is now employed. The coded or transponder key system was a second evolution that came about in the 1980s. The same approach is employed with the mechanical Ignition Lock Cylinder, but it is equipped with a chip in the key that needs to transmit the right code to the computer to allow the fuel and spark to be turned on, thus even when crooks force the lock the engine remains quiet. Subsequent push-button and keyless fob systems reduce fumbling, but are based on the same principles in modern Mazda 3 models. Even in newer examples, worn wafers or internal switch contacts might still result in no-crank, stalling, or part dropout, warning Mazda 3 owners that the Ignition Lock Cylinder or its companion switch might require replacement.
