if you get a stock honda remote i have a honda-tech thread somewhere with instructions to program it. i say just buy the honda clicker. the 03 LX came stock with keyless. did you buy it certified used? if so the dealer OWES you (free of charge as per honda certification) 3 keys, 2 key fobs, all the owners manuals...and i think that's it. i sell hondas at a dealer so i know.
