The Isuzu Ascender was a mid-size SUV built by General Motors for Isuzu. It was introduced for the 2003 model year and ended production on June 6, 2008, as part of Isuzu's withdrawal from the United States market. All model years of the Isuzu Ascender 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.
