Failing Ignition or Something Else?

Sometimes a bad ignition switch can be hard to identify. There are many different symptoms that can indicate that your ignition is failing. Some of those symptoms can also indicate other maintenance issues. Before we explore the most common symptoms tied to a failing ignition, lets first explore what your ignition switch is and what it does. With a little bit of understanding you can quickly identify the most common ignition issues and rule out the unrelated symptoms.

Your car’s ignition – Your cars ignition switch is similar to any electric switch, it interrupts the flow of electricity to and from one point to the next. In your car, the ignition switch operates the starter system for the engine and it controls the power source for a large part of the cars electronics.

Years ago all ignitions were similar, you put the key in and turned it. The turn sent power to the starter. You could also use the key to power other functions like the lights or the radio.

While modern cars still require an ignition, they look and operate a little differently. You will often find a transponder key system. The transponder key still requires you to put the key in and turn it to start, but it will also require the key to send the correct signal. If the proper signal isn’t received then the key will not turn. A keyless ignition system doesnt even require a key. Keyless ignition systems are growing in popularity. According to Edmunds, “by 2018, it was standard equipment on 62 percent of vehicles sold.” A keyless ignition system is defined as a passive RFID system. Your car sends out the code and the ignition chip receives it.
