I have taken all of mine to the dealer, the codes are fixed according to your vin# and there is a sequence to putting that code in. It cost about $25.00 the last one I had done and took about 5 min.

    I once took off the factory radio from my s10 99 chev blazer... to install an MP3 player... Then I sold the Mp3 player and had to reinstall the factory radio back on my blazer... It asked me for a code... and I didn't know where to find it... So I entered the year of my truck "1999" and it unlocked it. Try entering the Year of the model! It should work.
