The Ford Fusion is a mid-size car produced by the Ford Motor Company since the 2006 model year. As of 2018, all models of the Ford Fusion 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. However, most Ford Fusion's will require that you have 2 keyless entry remote fob smart keys in order to program a new keyless entry remote fob smart key.
