Pretty much. My clicker can open the door from around the corner of the townhouse as I pull into the driveway, but the fob only opens it once I round the corner and start heading toward the garage. I suppose if you bent down and put the fob against your head it would boost the range just like it does for the locks.
"The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong, it usually turns out to be impossible to get at or repair."
-Douglas Adams, Mostly Harmless
