Weister42: I'm going to try the antenna extension trick you posted as my RKE is pathetic too. I can be right up to the car and press unlock over and over turning the darn remote in all directions before it works. Yes - the batteries are new too. My 91 Eldo was fantastic and one press 40 feet away always worked.
I also want to see if I can access the "box" from the trunk. There is a felt panel that easily removes revealing all kinds of components hidden behind the rear seat. That would be easier than taking the back seat out.
