How do you change ignition key sensor and is it in the cylinder?

To change the ignition key sensor, you'll typically need to remove the ignition cylinder or housing first, which may involve detaching the steering column covers and disconnecting electrical connectors. The sensor itself is often integrated within the ignition cylinder assembly, so replacing the entire assembly may be necessary. Ensure you disconnect the battery before starting the process to avoid any electrical issues. Always refer to your vehicle’s service manual for specific instructions related to your model.
