| check your owner's manual/factory stereo book. the number is on a little card somewhere in there or something (not sure).... press the code button on the on-board computer, type the number in using the 1000, 100, 10, 1 keys at the top... for example if the first number is 7 you press the 1000 key 7 times, etc. after that press the SR button.
if you dont have the code, you have to go visit a dealer... which will cost you much
