To disable the alarm on a 2003 Chevy Impala, you can use the key fob to unlock the driver's door, which typically deactivates the alarm. If the remote is not available, insert the key into the driver's side door lock and turn it to the unlock position. If the alarm continues to sound, you may need to start the engine, as this can also reset the alarm system. If problems persist, consult the owner's manual for further instructions or consider disconnecting the battery temporarily.
