reset oil change light will not reset, any suggestions?

the change oil light will not go out after i follow the procedure in the owner's manual. any ideas for a cure??

What year is the car? Do you have an information panel? Or so, take it to oil %. Hold reset for about 10 sec. and it should change.

This worked on my girlfriend's Grand AM:
just put the keys in the ignition, turn it to "ON"(engine should be off) then depress the gas pedal all the way down 3 times, then turn the car on. The computer gets reset and the change oil light goes away. Try that.

I cant belive that no one asked him what type of GP he has :wink: ,is it a S.E/GT/GTP??? Since it makes a difference :iceslolan
