Last week, I saw a poor victim of this dilemma.. She had driven 600 miles from her home and shut off the vehicle. THEN she realized that she has lost her key fob !!. She had the entire car torn up looking for it with all four doors and trunk open.. It was a lexus or infinity SUV model. Who knows where the fob ended up but she DID have a large (and expensive) dilemma on her hands.. She would have to have it towed to a dealer, and they would have to custom build a new fob for her. $$$

I did a post last year when I was in the middle of a New Mexico desert and the situation occurred to me that if somehow the fob gets lost you are pretty much SOL!. One poster suggested always carrying the spare fob with it's battery removed just for this possible occasion.

KEEP TRACK OF YOU KEY FOB AT ALL TIMES!
