Shain, What isn't clear in your message is the description of your keys. If your ignition & door locks use the same key blank, then you have the one-key system. But someone may have replaced your ignition lock or who-knows-what. If your door key is shorter than the ignition key and (if OEM) has a small battery operated light then you have the earlier two-key system. Also, two-key system door locks are all black and a little larger than the one-key system which has a wide black ring and stainless keyhole. Walt Tampa, FL
