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.

Changed throttle position sensor and lost the aux power to the radio,, the door locks do not work correctly and no dome light, what went wrong?


Try unhooking the positive battery cable for about ten minutes. This will reset the cpu and place it into limp mode. As you drive the computer relearns your driving habit and chances are you will never notice the difference. often when electronic parts are changed the computer does not recognize the new part, but will on reboot.

Locked radio


You have to go to a chevy dealership to have them unlock the radio. They use a special code that will unlock the radio and then allows you to pick a new code. Hope this helps.

How do you reset the radio for a 2002 GMC 1500?


You will need to contact your local GM dealer with the VIN # proof of ownership & possibly the radio SIN # they will be able to retrieve the code for you if it is the original radio for your truck.
I know it's kind of late now but, If you need to replace your battery & don't have the code I recomend attaching another battery to the battery cables via booster calbes while you install the new battery.

I hope this helps
Farrout!
