How do you program the remote key fob on a 2001 Chevy Impala?
Turn off radio, leave ignition in accessory position... hold in tuner knob until it beeps into programming, and toggle into FOB Programming. Hold lock and unlock near dashboard for a few seconds. This should accomplish the task. Make sure your FOB is for an '01 Impala and the battery is good. Instructions are listed in the owners manual on how to do this. NOTE: If you have an aftermarket radio, then you are out of luck, as the Factory SRS Radio controls many of the ammenities of the vehicle.
