Repeat these steps for any additional remotes that you wish to program.The 2000 Chevrolet Impala has a driver-information center built into the factory radio. You'll use the factory radio to program a keyless remote to the vehicle. If your Impala has an aftermarket radio, you'll not be able to program a remote to the vehicle; the keyless-entry module is within the radio. Consider purchasing an aftermarket keyless-entry system if your Impala doesn't have the factory radio and you'd like to program a remote.
