The Ford Explorer Sport is a 3 door model of the Ford Explorer, which came in both rear-wheel drive and four-wheel drive variants. The Ford Explorer Sport's final year as its own model would come in 2003 and would later be designated as a trim level of the regular ford Explorer. All models of the Ford Explorer sport that were offered with the keyless entry remote fob smart key option were on-board programmable, meaning a person could program the keyless entry remote fob smart key with no special equipment other than the keyless entry remote fob smart key programming instructions.
