How to Start A Car With A Bad Ignition Switch? (Detailed)

How to Start A Car With A Bad Ignition Switch – An ignition switch is a vital component in any vehicle’s electrical system. It provides the electrical power to start the engine and also controls various functions of the vehicle, including the lights and accessories.

A bad ignition switch can cause numerous problems, including the inability to start the car or the car stalling while in use.

In this article, we will discuss the signs of a bad ignition switch, how to start a car with a bad ignition switch, how to test an ignition switch, what happens when the ignition switch goes out, and how to fix a bad ignition switch.

Signs of a Bad Ignition Switch

If your car is experiencing problems starting, it could be a sign of a bad ignition switch. Here are some common signs of a bad ignition switch:

Hard to Turn the Key

If you have trouble turning the key in the ignition, it could be due to a bad ignition switch. When the ignition switch is faulty, the key might not turn smoothly, and it might require more effort to turn.

The Vehicle Cannot Start

If you insert the key into the ignition and try to start the vehicle but nothing happens, it could be due to a bad ignition switch. If the ignition switch fails, the engine will not receive the necessary electrical power to start.

No Starter Motor Sound

When you turn the key in the ignition, and you don’t hear a starter motor sound, it could be due to a bad ignition switch. The starter motor requires electrical power from the ignition switch to start the engine, and if the switch is faulty, it won’t deliver the necessary power to the motor.

Stalling Vehicle

A faulty ignition switch can cause the vehicle to stall while in use. When the ignition switch is not working correctly, the engine might not receive the necessary electrical power to keep running, resulting in a stalled vehicle.

Stuck Steering Wheel

If the steering wheel is stuck or locked, it could be due to a bad ignition switch. The steering wheel could be locked in place because the ignition switch isn’t turning the wheel unlock mechanism.

How to Diagnose A Bad Ignition Switch

If you experience any of the above symptoms, it is advisable to get your vehicle checked by a mechanic. However, there are some steps you can take to diagnose a bad ignition switch.

First, check the battery to ensure it is charged and working correctly. If the battery is fine, you can try turning the key in the ignition and checking for any clicking or whirring sounds.

If you don’t hear any sounds, it could be due to a bad ignition switch.

How to Start A Car With A Bad Ignition Switch

If you find yourself with a bad ignition switch, there are some methods to start your car without replacing the switch. Here are some ways to start a car with a bad ignition switch:

Hotwiring

Hotwiring is a method used to start a car without a key. It is not legal and should only be used in emergency situations. Hotwiring a car is a complex process that requires an understanding of the vehicle’s electrical system.

If you have experience with electrical systems, you can try hotwiring your car. Here are the steps to hotwire a car:

Find the ignition wires: These wires are usually located under the steering wheel column and can be identified by their color codes.
Strip the wires: Cut off the insulation of the ignition wires and strip them to expose the copper wires.
Connect the wires: Connect the two wires, usually a red and a black wire, by twisting them together.
Turn the key: Turn the key to the “on” position, and the engine should start. If the engine doesn’t start, you might have connected the wrong wires, or the process wasn’t done correctly.

Hotwiring a car is not a recommended method to start a vehicle, and it should only be used in emergency situations. It is illegal and can cause serious damage to the vehicle’s electrical system.

The Drill and Screwdriver

Another method to start a car with a bad ignition switch is using a drill and screwdriver. This method is not recommended and should only be used in emergency situations. Here are the steps to start a car with a drill and screwdriver:

Remove the ignition switch cover: Use a screwdriver to remove the cover of the ignition switch. This will expose the lock cylinder.
Insert the screwdriver: Insert the screwdriver into the lock cylinder and turn it to the “on” position.
Use the drill: Use the drill to turn the screwdriver. The drill will create the necessary torque to turn the lock cylinder and start the car.

This method is not recommended as it can cause damage to the ignition switch and the vehicle’s electrical system.

Jumper Cables

Using jumper cables is a safer and legal method to start a car with a bad ignition switch. Here are the steps to start a car with jumper cables:

Locate the battery: Locate the battery of the car and the car with a good battery.
Connect the jumper cables: Connect the positive end of the jumper cables to the positive terminal of the good battery and the other positive end to the positive terminal of the bad battery.
Connect the negative end of the jumper cables: Connect the negative end of the jumper cables to the negative terminal of the good battery and the other negative end to a metal part of the car with the bad battery.
Start the car: Start the car with a good battery and let it run for a few minutes. Then, try starting the car with a bad battery.

Using jumper cables to start a car is a safe and legal method, but it requires another vehicle with a good battery.

How to Test An Ignition Switch

If you suspect a faulty ignition switch, you can test it using a test light. Here are the steps to test an ignition switch:

Connect the test light: Connect the test light to the ground on the vehicle.
Turn the key: Turn the key in the ignition to the “on” position.
Touch the test light: Touch the test light on the ignition switch’s connector, and it should light up.
Test the starter: Touch the test light to the starter relay connector. If it lights up, the ignition switch is working correctly.

Testing an ignition switch requires a test light, and it should only be done by a mechanic or someone with experience working on electrical systems.

What Happens When the Ignition Switch Goes Out

If the ignition switch goes out, it can cause numerous problems, including the inability to start the vehicle, stalling while driving, and failure of the electrical system.

It can also cause damage to other components of the vehicle, including the fuel pump, starter, and battery.

How to Fix A Bad Ignition Switch

If you have a bad ignition switch, you can fix it by replacing the switch. Here are the steps to replace the ignition switch:

Disconnect the battery: Disconnect the battery to avoid any electrical shocks.
Remove the steering wheel column cover. Use a screwdriver to remove the steering wheel column cover and expose the ignition switch.
Disconnect the wires: Disconnect the wires connected to the ignition switch. Note the position of each wire to ensure proper reinstallation.
Remove the ignition switch: Use a screwdriver to remove the screws holding the ignition switch in place. Remove the ignition switch from the steering column.
Install the new ignition switch: Install the new ignition switch and connect the wires to the proper positions.
Reinstall the steering wheel column cover: Reinstall the steering wheel column cover and reconnect the battery.

Replacing an ignition switch can be challenging, and it should only be done by a mechanic or someone with experience working on electrical systems.

Can You Force Reset A Switch?

Force resetting an ignition switch is not recommended, and it can cause serious damage to the electrical system.

If you suspect a problem with the ignition switch, it’s best to have it inspected and repaired by a qualified mechanic.
