How to Bypass Ignition Switch to Start Car: 6 Methods Explained

Introduction

An ignition switch is a component of a car’s electrical system that is responsible for connecting and disconnecting the battery from the starter motor. When the key is inserted into the ignition and turned, it sends an electrical signal to the starter motor, which then allows the car to start. However, when the ignition switch fails, it can be difficult to start the car.

In this article, we will explore 6 different methods for bypassing an ignition switch to start a car. Each method will be explained in detail, with potential risks discussed.

Using a Screwdriver to Manually Bypass the Ignition Switch

This method involves using a screwdriver to manually bypass the ignition switch. The steps are as follows:

• Locate the starter solenoid on the engine block.
• Remove the two small screws that hold the ignition switch in place.
• Connect the positive terminal of the battery to the starter solenoid.
• Turn the screwdriver clockwise until the starter engages.
• Start the car.

The potential risks associated with this method include damage to the electrical system, as well as the risk of electric shock.

Re-Wiring the Ignition Switch with a Jumper Wire to Bypass It

This method involves removing the ignition switch and re-wiring it with a jumper wire. The steps are as follows:

• Disconnect the battery.
• Remove the two small screws that hold the ignition switch in place.
• Connect the positive terminal of the battery to one end of the jumper wire.
• Connect the other end of the jumper wire to the starter solenoid.
• Start the car.

The potential risks associated with this method include damage to the electrical system, as well as the risk of electric shock.

Installing an Aftermarket Bypass Switch to Start the Car

This method involves installing an aftermarket bypass switch to start the car. The steps are as follows:

• Disconnect the battery.
• Locate the starter solenoid on the engine block.
• Install the bypass switch between the positive terminal of the battery and the starter solenoid.
• Turn the switch clockwise until the starter engages.
• Start the car.

The potential risks associated with this method include damage to the electrical system, as well as the risk of electric shock.

Replacing the Ignition Switch with a New Switch

This method involves replacing the ignition switch with a new switch. The steps are as follows:

• Disconnect the battery.
• Remove the two small screws that hold the ignition switch in place.
• Install the new ignition switch.
• Reconnect the battery.
• Start the car.

The potential risks associated with this method include damage to the electrical system, as well as the risk of electric shock.

Bypassing the Ignition Switch using a Remote Starter

This method involves bypassing the ignition switch using a remote starter. The steps are as follows:

• Install the remote starter unit according to the manufacturer’s instructions.
• Program the remote starter unit with the vehicle’s make, model, and year.
• Test the remote starter unit to ensure it is working properly.
• Press the button on the remote starter unit to start the car.

The potential risks associated with this method include damage to the electrical system, as well as the risk of electric shock.

Shorting Out the Ignition Switch with a Metal Object

This method involves shorting out the ignition switch with a metal object. The steps are as follows:

• Disconnect the battery.
• Locate the starter solenoid on the engine block.
• Place a metal object such as a screwdriver between the positive terminal of the battery and the starter solenoid.
• Turn the screwdriver clockwise until the starter engages.
• Start the car.

The potential risks associated with this method include damage to the electrical system, as well as the risk of electric shock.

Conclusion

Bypassing an ignition switch to start a car can be a tricky process. In this article, we have explored 6 different methods for bypassing an ignition switch, each with its own set of potential risks. It is important to remember that any modifications made to the electrical system should be done by a professional mechanic.
