When you turn the radio on after the power was pulled it will say "code". If your code is 12345 you press the buttons in this order "1-2-3-4-5", the radio will beep and turn on.
That's it.
The only reason the stickers are on the car in anyplace is because the dealership may put them there. The cars do not come from the factory with the stickers anywhere but on the card they are supposed to be on. There is NO PLACE ON THE CAR THAT THE RADIO CODE IS STAMPED FROM THE FACTORY!!!
