Normal Saturday morning... out doing grocery shopping. I got what I needed and went back to the car, pushed the switch above the license plate to open the trunk like I have done many times... nothing. Ok... try it again... nothing. Huh. Fished the fob out of my pocket and double clicked the trunk button... nothing. Tried unlocking the doors... nothing. I don't know if something like this has ever happened to you, but I was dumbfounded. Standing there with the ice cream melting... holy crap... now what do I do? Tried every way known to man to push the fob buttons to make something happen... nothing. I was going through a list of who I could call to go to my house and get the other fob from my wife, when it dawned on me... CELL PHONE APP!!! Used it to unlock the car, and then start it so I could drive home. This technology is awesome!! Got home and tried the other fob (after putting away the ice cream), and everything worked fine with the other fob. First fob still does not work, even after replacing the battery. Apparently I have experienced sudden fob failure syndrome. I called the Scottsdale Service Center, but apparently they no longer have Saturday hours. I'll call them Monday and see what I need to do to get the bad fob replaced. Weirdest feeling In the world when nothing happened. I'm still chuckling about it.
