The Chevrolet Cobalt was a compact car initially introduced by Chevrolet in 2004 for the 2005 model year. The Cobalt ended production on June 23, 2010. The keyless entry remote key fob smart key option was available on every Chevrolet Cobalt model produced. However, the Chevrolet Cobalt's remote key fobs were never on-board programmable. On-board programmable means a person can program the keyless entry remote key fob with no special equipment other than the keyless entry remote key fob programming instructions.
