I have only one master key (w/remote) and a new cut OEM remote key and a new cut valet key. Is it possible to “program” these new keys so that they can be used as a spare if need be?
I‘ve tried different methods but one published one states that for ’03 and ’04, a computer is needed to communicate with the ECU (to get it to recognize the new keys).
Anyone program their ‘03 LC without needing Techstream?
