Hi! I keep one fob wrapped in foil under a floormat. If I take a walk and lose the Fob in my pocket somewhere, I had a spare valet key made, cut off the top (to fit in my wallet) allowing enough for me to turn the key in the door lock and get in the vehicle.I like to carry a spare car key with me when I travel on long road trips. I carry it in my pocket at all times, while always using the primary key. Now that I have key fobs, what is the best way to do this? What are the implications of having both key fobs with me when I enter the car?
