Do any of you know how I can go from "two pushes" to open all 4 doors to just 1 "push" of the remote to open all 4 doors? I know the dealer can do this but it's a pain to go to the dealer and I am not due for any service anytime soon. '03 LS430.

 

Yeah I hate that 2 button push thing. Very annoying since if you don't push it the second time quick enough, the other 3 doors don't unlock. The only way to change the way this works is to reprogram the function in the CBEST system (Customized Body Electronics). Anyway, there's no way for the owner to reprogram CBEST unless they have the Lexus specific OBD II diagnostic tool.
