How to enter code to unlock radio in 2001 aztek

Unless you had replaced the BCM on your Aztek there is no reason you will need a code to unlock your radio. You can not unlock the radio by just entering a code. The dealer has to program it and it is done threw the internet. Approx $95.00 will program your Aztek.
