2000 Impala

I recently replaced the factory radio with a After market radio with digital display it will allow me to make changes to the security system but how can I change the other features ? Is this possible ? How do I reset the oil change light then ?

well i went throw all of that the thing is that the car has to have the original stereo install u cant take it off or else u cant reset nothing so what i did is they install the original stereo on my trunk for i could reset when i need to so i got 2 stereos install
