The unlock code varies from vehicle to vehicle and model to model, please check the owner's manual under radio and follow the instructions in the process you still have to knw the code for your radio which is usualy a sticker behind the radio unit itself un fortunately you have to remove the radio in order to read the code to instal it back into your radio

I heard that if you have the serial number of the car, that you can get the radio code to get it to work. Also, if the reason for having the code is so thieves that steal the radio cannot use the radio unless they have the code. If all they have to do is take out the radio and look at the sticker, they will have the code. What kind of protection is that.

    just google for the unlock code! it will give you like twenty or thirty ! print it off and try them till you find the right one ! circle it and keep it in your glove compartment

Who would be the dealership for a saturn 2000 ls ,i bought it used and radio needs code


Saturn is a GM product, take it to any Chevy dealer and they should be able to help you. Although, if the previous owner left the car manual in the glove box then the factory unlock code should be there, unless they previous owner changed the code then the dealer will have to reset it.

Try this site below. Seems like the only other choice besides the dealer. It's only costs $7.99, much cheaper than the dealer and they do GM vehicles. Follow the instructions on their Chevy site page to retrieve your radio serial number, which you will have to email to them, in order for you to get your unlock code.

I would have them take a good look at the fuel preasure and also the coil pack, as the car may run good at times and then skip whenever,hope this helps, also have they scanned the computer for stored codes as if its skipping the check engine light must be on.
