Tip:
Before you try making an ignition key for your car by using one of your car’s door locks, you will need to confirm that your previous older key was working on both the door lock as well as the ignition lock.

Check if you have a chip key

Check to see if your ignition switch has an anti theft system installed, (also known as a transponder chip key system), by the manufacturer. If your ignition switch does have an anti-theft system, making a key to start your car will require a professional locksmith to come to your vehicle’s location in order to connect a diagnostic key programming machine to your vehicle’s ECU, (your car’s computer), in order to register the new key to your car. You cannot program a key to your car without your car being present.

Tip:

Another good thing about the dealership is that you can provide them with your car’s VIN number and get information about what type of key your car requires.

  4. After you have the lock in your hand, take it to a local locksmith shop and ask them to make you a new key to your ignition using your door lock as a reference.
