The bag is not a bad size for a key fob and worked perfectly the first time I used it. It leaked the second time, however, and my electronic car key fob ended up soaked. Thank God it still worked! I would have been stranded otherwise. I really need a reliable product for my keys so the search continues....
Instructor Bill: FYI, these are not made to be submerged for any length of time. We generally put the keys in a hide a key magnetic holder and attach it to the car. Hope this helps.
