i used one from a 1992 lesabre -
Answer 1
The system will not let that key start the engine as it has no chip or the wrong one in it! Get some help from a locksmith or let a mechanic check it out. May be able to cut a key from the new one that has the right resistance chip in it. Will need the orginal key also. Locksmith should know what to do. -
