I bought this key fob because my Ford truck chip key had a ring hole torn off and I wanted the key to be on a keychain. My F150 key wouldn't fit in this well-made leather holder until I'd worn off most of the plastic. Note: Be careful when sharpening the chip key! After removing most of the plastic to the point where I could see the metal of the key itself, it fit snugly and worked to start the truck.
