How To Start A Car With A Bad Ignition Switch – 2023 Guide

A car’s ignition switch is a critical component that allows the engine to start and run. It is responsible for connecting the battery to the rest of the electrical system and the starter motor. However, like any other part of a vehicle, the ignition switch can fail, making it difficult or impossible to start the car.

If you’re experiencing issues with your car’s ignition switch, there are several ways to start your car. In this guide, we’ll cover the steps you can take to start a car with a bad ignition switch.

Symptoms of a Bad Ignition Switch

Before we dive into the different methods of starting a car with a bad ignition switch, it’s essential to understand the common symptoms of a faulty ignition switch. These symptoms include:

• The car won’t start or crank when you turn the key in the ignition.
• The dashboard lights come on, but the car won’t start.
• The key gets stuck in the ignition.
• The car starts but stalls immediately.
• The radio and other electrical components don’t work even when the car is running.
• The engine continues to run even after you’ve removed the key from the ignition.
• You have to wiggle the key or turn it multiple times to start the car.

How To Start A Car With A Bad Ignition Switch

If you’re experiencing any of above symptoms, your ignition switch may be faulty. You can try the following methods to start your car.

Use a Screwdriver

One of the easiest ways to start a car with a bad ignition switch is by using a screwdriver. Here’s how you can do it:

• Locate the ignition switch and remove the plastic cover around it.
• Insert a flat-head screwdriver into the ignition switch and turn it to the “on” position.
• Next, use the screwdriver to touch the two metal pins inside the switch. This will bypass the switch and send power to the starter motor.
• The engine should start. If it doesn’t, try turning the screwdriver a bit to make sure you’re making proper contact with the pins.

Use a Jumper Wire

Another way to start a car with a bad ignition switch is by using a jumper wire. Here’s how you can do it:

• Locate the starter motor under the car.
• Disconnect the small wire that runs from the starter solenoid to the ignition switch.
• Use a jumper wire to connect the starter solenoid directly to the battery’s positive terminal.
• Turn the ignition key to the “on” position, and the engine should start.

Check the Battery and Starter Motor

If your car’s ignition switch is faulty, it’s essential to ensure that your battery and starter motor are functioning correctly. Here’s what you can do:

• Check the battery: A weak or dead battery can cause issues with starting the car. Check the battery’s voltage with a multimeter. It should read around 12.6 volts. If it’s lower than that, you may need to charge or replace the battery.
• Check the starter motor: The starter motor is responsible for turning the engine over. If it’s faulty, the engine won’t start. You can check the starter motor by turning the key to the “on” position and listening for a clicking sound. If you hear a clicking sound, the starter motor is likely faulty and needs to be replaced.

Replace the Ignition Switch

If you’ve tried all the methods above and still can’t start your car, it’s time to replace the ignition switch. Here’s how you can do it:

• Disconnect the battery: Before you start working on the ignition switch, make sure you disconnect the battery to avoid any electrical hazards.
• Remove the ignition switch: Locate the ignition switch and remove it from the steering column. You may need to remove the steering wheel and other components to access the switch.
• Install the new ignition switch: Install the new ignition switch in place of the old one. Make sure you connect all the wires correctly

Take Your Car to a Mechanic

If you’re not comfortable working on your car’s ignition switch or you’ve tried all the methods above and still can’t start your car, it’s time to take it to a mechanic. A professional mechanic will have the necessary tools and expertise to diagnose and fix the problem.

It’s important to note that driving a car with a faulty ignition switch is dangerous and can cause serious accidents. So if you’re unable to start your car, it’s best to take it to a mechanic as soon as possible.

Preventative Measures

To prevent issues with your car’s ignition switch, it’s essential to practice good maintenance habits. Here are a few preventative measures you can take:

• Keep your keys in good condition: Worn or damaged keys can cause issues with the ignition switch. So make sure your keys are in good condition and not bent or damaged.
• Clean your ignition switch: Dirt and debris can accumulate inside the ignition switch and cause it to malfunction. So make sure you clean it regularly using a non-conductive cleaner.
• Avoid overloading your keychain: A heavy keychain can put pressure on the ignition switch and cause it to wear out faster. So keep your keychain light and avoid overloading it with too many keys or other items.
• Get regular maintenance: Regular maintenance and inspections by a professional mechanic can help detect any potential issues early on and prevent them from becoming major problems. So make sure you take your car for scheduled maintenance and tune-ups as recommended by the manufacturer.
• Protect your car from extreme temperatures: Extreme temperatures can cause damage to your car’s electrical system, including the ignition switch. So make sure you protect your car from extreme heat or cold by parking it in a covered area or using a car cover if necessary.
• Address any issues promptly: If you notice any issues with your car’s ignition switch or any other electrical component, address them promptly to prevent them from becoming bigger problems. Don’t wait until it’s too late to get your car repaired.

Final Words

A faulty ignition switch can be frustrating, but it doesn’t have to be the end of the world. By following the steps outlined above, you can start your car even with a bad ignition switch. However, it’s important to remember that driving a car with a faulty ignition switch is dangerous and can cause serious accidents. So if you’re unable to start your car, it’s best to take it to a mechanic as soon as possible. And to prevent issues with your car’s ignition switch, make sure you practice good maintenance habits.
