As stated on another thread, an 'Altoids' case works perfectly, and as stated leaves your fob smelling good! Just place the fob inside the Altoids case and cover with your towel or clothes.I placed it in the rear compartment, took out the little metal door key and placed it around my neck on a nylon cord. Additionally, you can buy an extra key from Scott at [email protected] for $29.95. This is MUCH cheaper than buying a spare from the Toyota dealer. Scott states he can also cut the key as a regular shape key if you so desire.
