Diagnosing a Failing Ignition Switch

The ignition switch turns on when you insert a key into the ignition, use a push button starting system or remotely start a vehicle. This switch sends signals to activate critical vehicle systems. As a result, a failing switch may lead to a variety of electrical problems, including a complete loss of power. Newer vehicles rely heavily on electronics, and a failing ignition switch may cause more than one system to malfunction.

If a vehicle stalls without indications of power loss, the ignition switch may be failing. If contacts are not made, open circuits may prevent a vehicle from starting. Start by checking the condition of the fuse and testing the voltage of the battery. If the engine does not crank and you also do not hear a click, the ignition switch could be the source of the problem.
