The Oldsmobile Alero was a compact car produced by the Oldsmobile division of General Motors from 1998 to 2004. The Alero was Oldsmobile's last compact car as well as the last vehicle sold under the brand. Oldsmobile Alero models do not have keyless entry remote fob smart keys that are onboard programmable and therefore require special equipment in order to program the keyless entry remote fob smart key.
