I have a 97 Pontiac Trans sport minivan that the previous owner must have locked up the GM cd player possibly by trying too many codes. Nothing is displayed such as LOC or INOP but the theftlock led is blinking. I found these instructions but they didn't work. The dealer wants to charge me $44. The dealer and the manual says I have to leave the key in the on position for 1 hour but then after that I'm not sure what to do. The manual says to press 1 and 4 for 10 seconds but that didn't work. These instructions say to hold 2 and 3 for 10 seconds but that didn't work. Any ideas? Thanks.
I also found these instructions that didn't work
pm me if you know the answer but don't want to announce it to the world. thanks
