I had to buy a new radio for my 2002 grand am gt. I bought a oem monsoon radio just like the one I pulled out. How do I unlock the new radio I just bought without going to the dealer?

you cant, you have to have it programmed by a GM dealership.

Copied from kingbain.com (link (http://anonym.to/?http://old.kingbain.com/how-to/unlock-gm-theftlock-radio-s.html)) I don't have a locked OEM radio, so I couldn't tell you this would work. But give it a shot.. Good Luck!
