The steering column of a vehicle and the dashboard are the two common locations for a car's ignition switch, according to Your Mechanic. This location makes it easy for the driver to start a vehicle and enables the transfer of power to the starter after a turn of the key.
If a car doesn't start or accessories don't work, it is a sign that the ignition switch isn't working. Replacing an ignition switch is often easy, according to Your Mechanic. Some repairs just require the removal of a few screws. However, others require the removal of the entire steering column to access the ignition switch.
