The Ford Expedition is a full-size SUV built by the Ford Motor Company. Introduced in 1996 for the 1997 model year as a replacement to the Ford Bronco, it was previously slotted between the smaller Ford Explorer and the larger Ford Excursion, but as of the 2005 model year, it is Ford's largest and last truck-based, off-road and tow-capable SUV. Some model years of the Ford Expedition have keyless entry remote fob smart keys that are onboard programmable, which means a person can program the keyless entry remote fob smart key with no special equipment other than the keyless entry remote fob smart key programming instructions. However, other model years of the Ford Expedition are not on-board programmable and require special equipment in order to program the keyless entry remote key fob.
