The Mazda3 or Mazda 3 is a compact car manufactured in Japan by the Mazda Motor Corporation. It was introduced for the 2004 model year. Some model years of the Mazda 3 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 Mazda 3 are not onboard programmable and require special equipment in order to program the keyless entry remote fob smart key.
