Can someone please give me another way to get my 4 digit code from GM for a locked Delco radio ?? The number that is plastered every where is NOT working and I am NOT paying the dealer $80.00 for the work I just did. Yes $80 is what I was just told at the dealer. I own the radio because I own the truck, but I'm supposed to pay another $80 for a code that should be free. The 1-800-537-5140 IS NOT WORKING. Please help. I have my 6 digit of 872 880. Now I just need the 4 digit. PLEASE ANYONE ?????

 

the fee you pay at the dealer is to help pay for the tool. theres no cheaper way around this. unless you can buy an unlocked radio but then theres cons to these and will prob cost as much as the dealer charges
