How To Bypass Ignition Switch – Step By Step Guide

Last updated on January 10th, 2023 at 08:50 pm

Ignition switches are an essential component of any vehicle, responsible for starting the engine and powering the electrical system. However, these switches can sometimes malfunction, rendering your vehicle unusable and leaving you stranded. In such cases, it may be necessary to bypass ignition switch to get your vehicle running again.

While this process can be intimidating for those who are not mechanically inclined, it is actually relatively straightforward and can be accomplished with a few basic tools.

In this article, we will provide a step-by-step guide on how to bypass ignition switch, including the tools and precautions you should take.

By following these steps, you can get your vehicle back on the road in no time.

What Is The Ignition Switch

The ignition switch, also known as the starter switch, is a switch found in most vehicles that allows the driver to start the vehicle’s engine. It is usually located on the dashboard or steering column, and is typically a spring-loaded button or lever.

The ignition switch has several functions, including turning on the electrical systems in the vehicle, such as the headlights and dashboard lights, and activating the starter motor to crank the engine.

It also has a locking function that prevents the vehicle from being started by anyone who does not have the key.

When the ignition switch is turned on, it sends an electrical signal to the starter motor, which then turns the engine over and starts it.

The ignition switch also sends a signal to the fuel system, which allows fuel to flow to the engine and begin the combustion process.

Can I Bypass Ignition Switch?

It is generally possible to bypass the ignition switch in a vehicle, but it is important to note that doing so can be complex and may require some mechanical knowledge and expertise.

It is also important to note that bypassing the ignition switch can potentially increase the risk of theft or misuse of the vehicle, and could cause issues with other systems in the vehicle.

We generally recommended to repair or replace a faulty ignition switch rather than attempting to bypass it. If you do decide to bypass the ignition switch, it is important to proceed with caution and to understand the risks involved.

How To Bypass the Ignition Switch


If you have a car that was manufactured before 1985, you may be able to hotwire it to bypass the ignition switch. Hotwiring a vehicle involves using a wire to connect the starter motor to the battery directly, allowing the vehicle to start without the use of a key.

This method is typically used for older vehicles that do not have complex electrical systems or security features.

To hotwire your vehicle, you will need to go beneath it and locate the steering column. Once you have found the steering column, remove the plastic covering the inside of the car.

You should see several wires inside. Look for the electrical harness that is usually placed at the center of the steering column, and be careful not to mix up the multiple connectors that may be located beneath the steering wheel.

Next, locate the battery, ignition, and starting connectors. The ignition is typically controlled through the yellow and brown wires, while the red wires are associated with the battery.

Strip the insulation off the red wires and twist them together. Then, connect the ignition on/off wire to the battery wire. This should turn on the lights and activate the electrical components in the vehicle.

To start the engine, cut the starting wire down to a half-inch length and attach it to the associated battery cables. Then, try revving the engine for a few minutes.

If the engine starts, allow it to run for a few more minutes to charge the battery, and then carefully disconnect the wire from the starter motor and the battery.

Jump Starting The Car

Here’s what you need to do:

  1. First, park the two cars close to each other but make sure they are not touching.
  2. Turn off both cars completely.
  3. Locate the positive terminal of the ignition coil and the positive side of the battery on your car.
  4. Take the red (+) clamp and attach it to the positive terminal of the ignition coil.
  5. Locate the starting solenoid and attach the other end of the red (+) clamp to it.
  6. Connect the solenoid’s terminal to the spot where the ignition switch is attached after removing the solenoid’s ignition switch wire.

The purpose of these steps is to provide electricity to the dashboard so that you can start your car using the starting solenoid.

Once you have completed these steps, you should be able to start your car. Just make sure to follow all safety precautions when working with cars and jumpstarting.

Signs Of A Faulty Ignition Switch – When You Bypass It?

Can You Bypass the Ignition Switch?

One common sign of a faulty ignition switch is difficulty starting the car. This can include having to jiggle the key in the ignition or repeatedly turning the key before the car will start. If you’re experiencing intermittent issues with starting the car, this can also be a sign of a faulty ignition switch.

Other electrical issues, such as flickering headlights or dashboard lights, can also indicate a problem with the ignition switch. If your car is stalling while driving or having difficulty staying on, this could also be a sign of a faulty ignition switch.

Finally, if the key is getting stuck in the ignition, this can be a sign of a problem with the ignition switch.

If you’re experiencing any of these issues, it’s a good idea to have a mechanic take a look at your ignition switch to determine if it needs to be repaired or replaced.

In conclusion, bypassing an ignition switch can be a useful solution in an emergency situation when you are unable to replace the faulty switch right away. However, it is important to remember that this is only a temporary fix and you should plan to have the ignition switch replaced as soon as possible

With the right tools and knowledge, you should be able to successfully bypass the ignition switch and get your car running again. Just be sure to follow all safety precautions and consult a mechanic if you are unsure of the process.

If you are unsure of the process or do not feel comfortable attempting it yourself, it is always best to consult a professional mechanic for assistance.
