Access Tools' Spare Tire Kit provides the user with the right key for most vehicles with an under-mounted spare tire. These keys allows for quick and easy spare tire removal, eliminating the need to search the vehicle's truck for the spare tire key. The kit, which comes with 15 socket-based keys, works on any SUV and pickup truck, as well as many other new vehicles, including the Mini Cooper and Fiat 500. The kit is periodically updated to ensure functionality and usability, the manufacturer says.
