Well, I disagree with your first statement, I haven’t had to “click a button” in probably 15 yrs. This is the first car I’ve ever had a problem with since the advent of keyless entry going back to my first experience with it in my 2003 Mercedes. As far as a battery, I will give it a try simply because it’s cheap and easy, but this has been going on for several months, often works like it should, sometimes gives me problems. I would think a weak or dead battery would cause it to fail most of the time. I would also think it wouldn’t allow the car to drive, and might even pop up a message about key fob battery being low on the screen (several of my other cars do that, not sure if the Lucid has that ability or not)
