I'm replacing my ignition cylinder with the key. I know they come with a key code but if I buy one without a key code will the car turn on or do I have to do something extra. My original one was turning and wouldn't turn on. I bought a used one but it had a key code and thus I was forced to used my old key and the new one but my old one was damaged so my car won't start since it doesn't have the original key code, now I want to buy a new onewithout a key code but will it work
