8 Steps on How to Change a Ignition Lock Cylinder Without Key
Step 1: Disconnect the Negative Battery Terminal
Before starting the process, it is crucial to disconnect the negative terminal of the car battery. This step ensures your safety by preventing accidental electrical shocks or short circuits while you work on the ignition system. Locate the car battery, typically found under the hood, and identify the negative terminal, marked with a “-” symbol. Use a wrench to loosen the nut securing the negative cable.
Once loosened, carefully remove the cable and set it aside, ensuring it does not come into contact with the battery or any metal components. This precautionary measure provides a safe working environment throughout the replacement process.
Step 2: Remove the Steering Column Cover
To access the ignition lock cylinder, you will need to remove the steering column cover. The cover is usually held in place by screws that are located underneath or on the sides of the steering column. Use the appropriate screwdriver, either Phillips or flathead depending on your vehicle, to carefully remove these screws.
Once the screws are undone, gently pry apart the upper and lower sections of the steering column cover. Take care not to apply excessive force to avoid damaging the plastic components. If necessary, refer to your vehicle manual for the exact screw placement and cover removal instructions. Set the screws and cover pieces aside in a safe location to ensure they are not misplaced. With the cover removed, you now have clear access to the ignition lock cylinder and adjacent components.
Step 3: Remove the Ignition Switch
Next, you will need to remove the ignition switch, which is located behind the ignition lock cylinder. Use a wrench to loosen and remove any bolts or screws securing the switch in place. Carefully disconnect any electrical connectors attached to the back of the ignition switch.
Depending on your vehicle’s make and model, there may be multiple connections that need to be removed. Keep track of these connectors to ensure they are reconnected properly during reassembly.
