Forum Thread: Can I Replace My Isuzu Ignition Switch After I Have Lost My Keys?

Not sure, but you should call your nearest dealership and ask about getting a new set of keys. If you've got proof of ownership and give them the VIN, they might be able to cut you a new key without even seeing the vehicle. You can even try and ask them what the key code is for your vehicle and give it to the locksmith to do instead.
