How to Replace Car Ignition Switch?

If you’re having trouble starting your car, and you’ve ruled out the battery, starter, and alternator, your ignition switch may be the culprit. Over time, the contacts in the switch can wear out, which prevents the electrical current from making its way to your engine. However, replacing the ignition can be a relatively simple project as long as you have the right tools and know-how. Here’s everything you need to know about how to replace a car ignition switch.


What You’ll Need

Before you start any project, make sure you have all the necessary tools on hand. Here’s a list of everything you’ll need to replace your ignition switch:

  • Screwdrivers (flathead and Phillips head)
  • Pliers (needle-nose and regular)
  • Socket wrench set
  • New ignition switch

Step-by-Step Guide

Follow these steps, and you’ll be on your way to replacing your car’s ignition switch.

Step 1: Disconnect The Battery

Whenever you’re working on any electrical systems in your car, you want to make sure you disconnect the battery. This ensures that you don’t accidentally short out any circuits or damage your car’s computer.

Step 2: Remove The Steering Column Cover

To get at the ignition switch, you’ll need to remove the cover from around the steering column. This is usually held in place by a few screws that can be accessed from underneath the column.

Step 3: Disconnect The Ignition Switch Wiring

Once you have access to the ignition switch, you’ll need to disconnect the wiring harness that connects it to the rest of the car’s electrical systems. This can be done by gently pulling it apart or using pliers to help loosen any stuck connections.

Step 4: Remove The Old Ignition Switch

With the wiring disconnected, you can remove the old ignition switch from the steering column. This usually involves removing a few screws or bolts that hold the switch in place.

Step 5: Install The New Ignition Switch

Now that you’ve removed the old ignition switch, it’s time to install the new one. Follow the instructions that came with your new switch to make sure you attach it correctly. This might involve bolting it in place or screwing it down.

Step 6: Reattach The Wiring

Once the new switch is in place, you’ll need to reattach the wiring harness that you disconnected earlier. Make sure each connection is tight and secure, and that none of the wires are exposed.

Step 7: Reassemble The Steering Column

With the new switch installed and the wiring reattached, it’s time to put everything back together. Reattach the steering column cover using the screws you removed earlier, and double-check that everything is tight and secure.

Step 8: Reconnect The Battery

Finally, reconnect the battery. This should restore power to your car, and you should be able to turn the key and start the engine.
