Sand in the fob or no key at all, we handle it at the car.

Sand and salt water are the two ingredients that ruin keys here, and the beach makes both unavoidable. A day near the sand line at Fort Lauderdale Beach or Lauderdale-by-the-Sea leaves grit packed into a key blade and worked into the seams of a fob case, where it grinds against the contacts every time the button gets pressed. Anyone who takes the fob into the water is on a shorter clock, because salt keeps drawing current across the board long after the plastic looks dry. Then there is the volume side of it. Port Everglades turns over entire ships of passengers at once, and the terminal lots and offsite cruise parking fill with cars nobody touches for a week or two while a key sits at the bottom of a suitcase somewhere in the Caribbean. Long-term parking at the airport does the same on a daily cycle. Add a boating town where crew and owners hop between the docks along the New River and the Intracoastal with keys shared among several people, and drawbridge traffic that makes any unplanned trip across town expensive in time. We come to whichever slab of concrete your car is sitting on.
