Answer 1

Answer 2

Your radio is probably one of the radios using Theftlock I, which requires a code to be entered. You'll usually have to ask a dealer for the code to reset the radio, which is unique to each radio.

Answer 3

You, or a previous owner, activated the theft deterrent option by entering a personal security code. If the code is unknown, press and hold the 2 and 3 buttons at the same time until 3 number show on the display. Write them down. Then press the AM/FM button and 3 more numbers will show. Write them down. With these 6 numbers, a GM dealer can call and get your security code. You will use the HR and MIN buttons to enter the code and then press AM/FM.
