What is a Chevy Ignition Switch?
Your Chevy’s ignition switch is also called a starter switch.
It is a component of your Chevy’s control system.
Its primary function is to activate your vehicle’s electrical systems, including the power windows, radios, and more.
Chevys with an internal combustion engine have ignition switches that power the components of the ignition system.
The ignition system includes the ignition coil and the control unit of your Chevy’s engine.
The ignition switch also powers the vehicle’s starter solenoid for activating the starter motor.
Your Chevy’s ignition starts when you turn the ignition key after inserting it into the slot.
You can turn the key into four different positions, including on, lock, acc, and start.
How to Bypass Chevy Ignition Switch [03 Methods]
Newer Chevy models have put more security measures to prevent bypassing the ignition switch.
However, it is much easier to bypass the ignition switch of older Chevy truck models.
However, we advise that you take extreme caution when messing around with your Chevy’s wiring.
In addition, you should consult your Chevy’s manual to enable you to identify the correct color codes of your truck’s model.
Do not use any of these methods except if you own the Chevy truck.
Here are three different methods you can use to bypass your Chevy’s ignition switch:
01. Hot-Wiring Your Chevy’s Steering Column
One of the ways to bypass your Chevy’s ignition switch is by hot wiring the steering column.
Before starting the process, check your Chevy’s owner manual to be sure you can override the gear selector and steering column.
It is critical to need that you may damage your Chevy’s steering column and shifting mechanism while attempting this method.
The first step is removing your steering column’s plastic cover. The plastic covers are secured using concealed clips or screws.
Free the access panels by removing the screws or clips.
Some older Chevy models may require you to break the ignition locking pins by forcing a screwdriver into Chevy’s keyhole.
A hammer is needed for driving the screwdriver into the keyhole.
The next step is to locate your Chevy’s wiring harness connector.
Once you do that, the electrical wires become exposed.
You don’t have to be confused by the sight of different wires.
It is vital to know what each wire represents.
The wires may be categorized into three.
The first is the Wires that lead to the column controls, including cruise control.
The second category of wires controls your Chevy’s seat warmers or wipers.
Finally, the last set of wires leads to your Chevy’s starter, ignition, and battery.
Your primary focus is wired leading to the starter wire bundle, ignition, and wire.
There are three wires in this category, and each has a distinctive color.
It is vital to check your Chevy’s manual to identify each wire correctly.
In some cases, the starter wires are yellow, the battery wires are red, and the ignition wires are brown.
Strip and twist together 2.5cm of the battery wires.
Use an electrician tape to wrap the wires and avoid allowing them to touch any metal component in your Chevy’s truck.
By connecting these wires, you provide the ignition components with electricity.
It also powers your engine when you turn the starter.
The next step is to connect the battery wire to the ignition wire.
Once you do this, your Chevy’s electrical components will become active.
At this point, you can listen to the radio but may need to spark the starter wire to drive your truck.

However, before you can successfully drive your truck, there is one more thing to do.
You have to break the steering lock.
Some Chevy models require popping off the metal keyhole.
It releases the spring and breaks the steering lock.
Jamming a screwdriver into the keyhole would also break the lock for older models.
For some Chevy models, you may crank the wheel to either side for it to be free.

02. Drilling the Lock Pins
Drilling the lock pin is another method to bypass the ignition switch.
Your primary aim is to destroy the lock pins so that you can turn your truck with the aid of a screwdriver instead of a key.
You may use this method if you lose your Chevy’s key.
Once you are set, you should drill into the keyhole about the length of your Chevy’s key.
There are two sections and a spring in every lock pin.
To ensure the bits fall into place, it is advisable to drill the keyhole more than once.
The final step involves placing the screwdriver into the keyhole as if it were your Chevy’s key.
You may not need to insert the screwdriver deep into the keyhole since the pins are already broken.
Slightly turn the screwdriver in a clockwise direction to try and start your Chevy’s engine.
The drawback of this method is that it may damage your Chevy’s key switch.
It may also make your Chevy vulnerable to theft because anyone can steal your truck provided they have a strong fingernail or a screwdriver.

03. Powering the Dash
The final method you can bypass your Chevy’s ignition switch is by powering the dash.
Open your Chevy hood and find the red coil wire.
You can find the coil and plug wires at the end of all types of V8 engines.
If your Chevy uses a four-cylinder engine, the plug and coil wires may be spotted on the right side close to the engine centre.
For Chevy’s with six-cylinder engines, the coil and plug wires may lie on the left side close to the middle of the engine.
Once you have located the coil and plug wires location, the next thing is to bring out your jumper cables.
The approach involves running your jump cable from your battery’s positive terminal to the red wire leading to the coil or the positive sides of the coil itself.
Once you have made the connection, your Chevy dashboard becomes activated.
The next step is to locate your Chevy’s starter solenoid and place a screwdriver with a flat blade in the centre of your truck’s steering column.
Next, try to push the screwdriver between the column and the wheel.
The aim of doing this is to disengage the locking pin from your Chevy’s wheel.
You may have to apply some effort to achieve this.
Disengaging the locking pins may not set off any alarms.
After removing the locking pins, you may find the solenoid.
The final step is to connect the positive terminal of your truck’s battery to the solenoid.
You may find a small wire above the positive battery terminal and the solenoid.
First, ensure you separate the solenoid from the ignition switch wire with an insulated screwdriver.
Next, connect the positive post of the solenoid to the same terminal connecting your ignition switch.
Making this connection ensures your battery delivers 12 volts.
The voltage supply from your Chevy’s battery activates the solenoid.
It also helps the starter to crank your truck.
