Q: How to replace the ignition switch and lock cylinder on Honda Fit?
A: Make sure to have the audio security codes handy for reprogramming the audio system. Disconnect the cable from the negative terminal of the battery. Remove the steering column covers and disconnect the electrical connector from the ignition switch. Remove the mounting fasteners and pull the switch from the lock cylinder housing, ensuring the hub of the new switch is aligned with the blade on the ignition Lock Cylinder during installation. The remainder of installation follows the reverse order of removal. Reconnect the battery and perform the necessary re-learn procedures. Remove the steering column from the car, then center punch and drill out the break off bolts securing the housing to the steering column shaft, discarding them. Remove the remaining sections of the break off bolts from the steering column housing and take out the lock housing. Install the replacement housing loosely with the new break off bolts provided, insert the key, and turn it several times to ensure it works freely, which will also help align the steering wheel lock correctly. Tighten the break off bolts until they shear off completely, and complete the installation in reverse order. Finally, reconnect the battery and perform the necessary re-learn procedures.
