Recently My husband lost our only set of car keys and are living on a fixed income and he thinks replacing ignition is gonna be cheaper but no matter what I tell him he won't listen it cost the same.. for a new ignition I think it cost about 400 for a new ignition. Not including the programing the new key. Well about a year before he lost our car keys the lil black button I guess it's called a key fob well he just found that. And I'm hoping that might be a way for us to save money it don't have the key on it it's just a button to lock and unlock the doors will that be of any help to us in hopes of getting a key made for our car or is that a useless part?as I'm sure you can tell by reading this I'm a woman and don't know anything about cars and hope we might have gotten lucky finding this lil lock button
