An ignition is a critical part of a vehicle. It is responsible for starting the engine, and without it, the car will not be able to run. If your ignition is not working properly, it is important to replace it as soon as possible. Replacing an ignition can be a challenging task, but it is one that can be completed with the right tools and knowledge.
The first step is to remove the old ignition. This can be done by removing the screws that hold it in place. Once the screws are removed, the ignition can be pulled out of the dashboard. Be careful not to damage any of the wires or connectors when removing the ignition.
Once the old ignition has been removed, the new ignition can be installed. The new ignition should be plugged into the same connectors as the old ignition. Once the new ignition is plugged in, the screws can be tightened to hold it in place. Be sure to tighten the screws securely, but do not overtighten them. Once the screws are tightened, the new ignition will be installed and the car will be able to start again.
Removing the Steering Wheel
Before removing the steering wheel, it’s crucial to ensure that the vehicle’s battery terminals are disconnected. This safety precaution prevents any potential electrical hazards.
To remove the steering wheel, follow these detailed steps:
-
Locate the steering wheel bolts: On most vehicles, there will be two or four bolts located behind the steering wheel. These bolts are typically covered by plastic covers or trim pieces that can be easily removed by prying them off with a flat-head screwdriver or trim removal tool.
-
Remove the bolts: Use an appropriate socket wrench or spanner to loosen and remove the steering wheel bolts.
-
Pull the steering wheel straight towards you: Once the bolts are removed, carefully pull the steering wheel straight towards you to detach it from the steering column. Avoid jerking or twisting the wheel, as this could damage the steering mechanism.
-
Disconnect any electrical connectors: If your steering wheel has any electrical connectors for airbags, cruise control, or audio controls, locate and carefully disconnect them.
-
The steering wheel is now removed: It can be set aside in a safe place while you move on to the next steps of the ignition replacement process.

- Screwdriver
- Wiring harness connector release tool (optional)
- Difficulty starting the car
- Engine stalling
- No power to the spark plugs
- No power to the fuel injectors
Disconnecting the Ignition Switch
Materials You’ll Need
Step 1: Locate the Ignition Switch
The ignition switch is typically located on the steering column. It’s usually behind a plastic cover that you’ll need to remove.
Step 2: Disconnect the Negative Battery Terminal
Important: Before you disconnect any electrical components, make sure the negative terminal of the battery is disconnected. This will prevent any accidental short circuits.
Step 3: Remove the Steering Column Cover
Use a screwdriver to remove any screws holding the steering column cover in place. Once the screws are removed, carefully pry off the cover.
Step 4: Disconnect the Electrical Connector
Find the electrical connector that connects to the back of the ignition switch. If you have a wiring harness connector release tool, use it to depress the locking tab on the connector. Otherwise, you can carefully pull the connector straight off the switch.
Step 5: Remove the Ignition Switch Mounting Screws
Typically, there are two screws that secure the ignition switch to the steering column. Locate these screws and remove them.
| Screw Size | Location |
|---|---|
| Phillips #2 | Top of the ignition switch |
| Phillips #2 | Bottom of the ignition switch |
Note: The screw sizes and locations may vary depending on the vehicle model.
Step 6: Pull Out the Ignition Switch
Once the mounting screws are removed, gently pull the ignition switch out of the steering column. The switch should come out easily.
Reconnecting the Ignition Switch
Step 8: Reassemble the Ignition Lock Cylinder
With the ignition switch removed, it’s time to reassemble the ignition lock cylinder. Begin by inserting the new ignition key into the cylinder and turning it clockwise until it clicks in place. This will align the lock cylinder with the key pins.
Next, insert the flathead screwdriver into the small hole located on the bottom of the ignition lock cylinder. This hole is designed to release a spring-loaded detent that secures the lock cylinder in place. Pressing inward on the screwdriver will release the detent, allowing you to pull the lock cylinder straight out of the housing.
With the lock cylinder removed, lubricate the shaft with a small amount of white lithium grease. This will help prevent wear and tear and ensure smooth operation. Carefully slide the lock cylinder back into the housing, aligning the key pins with the holes in the housing. Ensure that the lock cylinder is properly seated and locked in place with the detent.
Finally, reconnect the electrical wires to the ignition switch. Refer to the wiring diagram for the correct wire colors and connections. Make sure the wires are securely connected and protected with electrical tape.

| Red | +12V Battery Power |
| Black | Ground |
| Blue | Start Signal to Starter |
