How to disconnect and replace the ignition lock cylinder and ignition switch on Mazda 3?

Disconnect the cable on the negative on the battery. Disassemble the lower side of the trim panel of the driver side, knee bolster (where fitted), the bottom cover of the upper and bottom cover of the steering column, and also the steering column to the lowest level. Be careful and do not take the ignition switch and the key lock cylinder at the same time because it may harm the steering column. Turn the locking lever down and pull the electrical connector off the ignition switch, and press the release tabs to remove the ignition switch out of the steering column. When installing, make sure that the switch needs to be turned on and on the other hand, it needs to be turned off. In the case of the key lock cylinder, insert a small screwdriver or pick on the release button of the key lock cylinder and remove the key lock cylinder with the ignition key on ACC position. Installation To install the key lock cylinder, position the key lock cylinder into the housing and push it until it clicks. Ensure that the ignition switch is in a good working condition in the OFF, ACC, BIN, and Start positions, and fit it in the reverse order of removal. Lock cylinder replacement does not require the lock cylinder to be removed to strip off the illumination ring, but should be disconnected off the illumination ring, the lock tabs disengaged and the illumination ring removed, making sure it clips together during installation.

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.
