All I have for my 99' LC is one of these keys seen below and the lock /unlock remote end that broke off of another key. How do I get another key with the transponder in it, (like below, i don't need they keyless fob I have an aftermarket alarm system) without going to a st(d)ealer? There are a bunch of keys on ebay but how do I know that they will really work? Stealer here quoted me $280 just for the key without programing??? huh??? I need a !!!!!!!!!
