this is probli a stupid q. and i probli kno the answer but im upset right now and totally cant think. ok. karl has a set of my keys which i gave to him so i alwayz had a set that my mom cudnt get a hold of. but now that i dont live with mom anymore. and karl and i are done. (im mostlikely getting a restraining order against him.) either way i want to kno if theres a way to change the key for the ignition. and how much it wud run me.... all the locks i can do myself. that much i can remember right now. but my car is my baby. and the last thing i need is karl tryin to **** with it.
