To reset the key for a Chevrolet Impala, first, ensure that you have the vehicle's ignition key and the key fob. Insert the key into the ignition and turn it to the "On" position without starting the engine. Press and hold the "Lock" and "Unlock" buttons on the key fob simultaneously for about 15 seconds until you hear a chime, indicating the reset is complete. Finally, turn the ignition off and test the key fob to ensure it is functioning properly.

The key fob uses radio frequency signals to communicate with the car's security system. When the button on the key fob is pressed, it sends a signal to the car's receiver, which then unlocks the doors or starts the engine.
Well that question is too general. What year and what make is the vehicle? Is it a brand new key fob? If it is brand new it may need to be programed to the vehicle. The battery may be dead in the fob. The fob may also have a broken contact inside of it. I recommend taking your key fob and vehicle to the dealer for diagnosis.
