Question about 2002 Chevrolet Blazer
There is no code in this year Blazer radio. The radio has the VIN encoded in it and when you turn on ignition the BCM (Body Computer Module) compares it's VIN to that of the radio and if they don't match, the radio is locked out.
Radio is unlocked through the GM Tech 2 scan tool. Dealers will do this for an outrageous fee ($40 - $100+) for just a few minutes time.
