The Dodge Stratus was a mid-size 4-door family sedan introduced in 1995. Some model years of the Dodge Stratus 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 are not onboard programmable and require special equipment in order to program the keyless entry remote fob smart key. The Dodge Avenger replaced the Stratus nameplate in early 2007 for the 2008 model year.
