How to Replace the Car Ignition Lock Cylinder?
2 Answers
Car ignition lock cylinder replacement method: 1. Remove the plastic cover and use a hex screwdriver to disassemble the ignition switch; 2. Unplug the ignition switch connector, detach the lock cylinder, and install the new lock cylinder. When installing the lock cylinder, insert the key into the lock cylinder, turn it to the I position, and press the metal block on the ignition switch surface. If the ignition switch is not removed, the metal block cannot be pressed. The ignition lock cylinder, also known as the ignition switch, is a multi-position switch that requires a corresponding key to operate. The ignition lock is typically used to control the ignition circuit, instrument circuit, electronic control system (engine), starting circuit, and auxiliary electrical circuits.
Replacing a car's ignition lock cylinder might sound professional, but just follow the steps. From my experience changing it a few times: First, safety first—disconnect the negative battery cable to prevent short circuits and damage. Next, remove the steering column cover underneath the wheel using a small screwdriver to take out the screws, but don’t force it to avoid damaging the plastic. Then locate the ignition lock cylinder, use pliers to loosen the retaining clip—you might need to turn the key to the "run" position to pull out the old cylinder. If it’s stuck, don’t yank it; gently wiggle it loose. When inserting the new cylinder, make sure it aligns with the slot, secure the clip, and don’t forget to test if the key turns smoothly. If it does, reattach the cover and reconnect the battery to test the car. The whole process takes about half an hour, with simple tools like a screwdriver and pliers. If you can’t manage it, visit a repair shop—accidentally triggering the anti-theft system could be troublesome.
